Elenco dei parametri

uri

A » mongodb:// connection URI:

mongodb://[username:password@]host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[defaultAuthDb][?options]]

Defaults to "mongodb://127.0.0.1:27017" if unspecified.

For details on supported URI options, see » Connection String Options in the MongoDB manual. » Connection pool options are not supported, as the extension does not implement connection pools.

The uri is a URL, hence any special characters in its components need to be URL encoded according to » RFC 3986. This is particularly relevant to the username and password, which can often include special characters such as @, :, or %. When connecting via a Unix domain socket, the socket path may contain special characters such as slashes and must be encoded. The rawurlencode() function may be used to encode constituent parts of the URI.

The defaultAuthDb component may be used to specify the database name associated with the user's credentials; however the authSource URI option will take priority if specified. If neither defaultAuthDb nor authSource are specified, the admin database will be used by default. The defaultAuthDb component has no effect in the absence of user credentials.

uriOptions

Additional » connection string options, which will overwrite any options with the same name in the uri parameter.

uriOptions

Option	Type	Description
appname	string	MongoDB 3.4+ has the ability to annotate connections with metadata provided by the connecting client. This metadata is included in the server's logs upon establishing a connection and also recorded in slow query logs when database profiling is enabled. This option may be used to specify an application name, which will be included in the metadata. The value cannot exceed 128 characters in length.
authMechanism	string	The authentication mechanism that MongoDB will use to authenticate the connection. For additional details and a list of supported values, see » Authentication Options in the MongoDB manual.
authMechanismProperties	array	Properties for the selected authentication mechanism. For additional details and a list of supported properties, see the » Driver Authentication Specification. Nota: When not specified in the URI string, this option is expressed as an array of key/value pairs. The keys and values in this array should be strings.
authSource	string	The database name associated with the user's credentials. Defaults to the database component of the connection URI, or the admin database if both are unspecified. For authentication mechanisms that delegate credential storage to other services (e.g. GSSAPI), this should be "$external".
canonicalizeHostname	bool	If true, the driver will resolve the real hostname for the server IP address before authenticating via SASL. Some underlying GSSAPI layers already do this, but the functionality may be disabled in their config (e.g. krb.conf). Defaults to false. This option is a deprecated alias for the "CANONICALIZE_HOST_NAME" property of the "authMechanismProperties" URI option.
compressors	string	A prioritized, comma-delimited list of compressors that the client wants to use. Messages are only compressed if the client and server share any compressors in common, and the compressor used in each direction will depend on the individual configuration of the server or driver. See the » Driver Compression Specification for more information.
connectTimeoutMS	int	The time in milliseconds to attempt a connection before timing out. Defaults to 10,000 milliseconds.
directConnection	bool	This option can be used to control replica set discovery behavior when only a single host is provided in the connection string. By default, providing a single member in the connection string will establish a direct connection or discover additional members depending on whether the "replicaSet" URI option is omitted or present, respectively. Specify false to force discovery to occur (if "replicaSet" is omitted) or specify true to force a direct connection (if "replicaSet" is present).
gssapiServiceName	string	Set the Kerberos service name when connecting to Kerberized MongoDB instances. This value must match the service name set on MongoDB instances (i.e. » saslServiceName server parameter). Defaults to "mongodb". This option is a deprecated alias for the "SERVICE_NAME" property of the "authMechanismProperties" URI option.
heartbeatFrequencyMS	int	Specifies the interval in milliseconds between the driver's checks of the MongoDB topology, counted from the end of the previous check until the beginning of the next one. Defaults to 60,000 milliseconds. Per the » Server Discovery and Monitoring Specification, this value cannot be less than 500 milliseconds.
journal	bool	Corresponds to the default write concern's journal parameter. If true, writes will require acknowledgement from MongoDB that the operation has been written to the journal. For details, see MongoDB\Driver\WriteConcern.
loadBalanced	bool	Specifies whether the driver is connecting to a MongoDB cluster through a load balancer. If true, the driver may only connect to a single host (specified by either the connection string or SRV lookup), the "directConnection" URI option cannot be true, and the "replicaSet" URI option must be omitted. Defaults to false.
localThresholdMS	int	The size in milliseconds of the latency window for selecting among multiple suitable MongoDB instances while resolving a read preference. Defaults to 15 milliseconds.
maxStalenessSeconds	int	Corresponds to the read preference's "maxStalenessSeconds". Specifies, in seconds, how stale a secondary can be before the client stops using it for read operations. By default, there is no maximum staleness and clients will not consider a secondary’s lag when choosing where to direct a read operation. For details, see MongoDB\Driver\ReadPreference. If specified, the max staleness must be a signed 32-bit integer greater than or equal to MongoDB\Driver\ReadPreference::SMALLEST_MAX_STALENESS_SECONDS (i.e. 90 seconds).
password	string	The password for the user being authenticated. This option is useful if the password contains special characters, which would otherwise need to be URL encoded for the connection URI.
readConcernLevel	string	Corresponds to the read concern's level parameter. Specifies the level of read isolation. For details, see MongoDB\Driver\ReadConcern.
readPreference	string	Corresponds to the read preference's mode parameter. Defaults to "primary". For details, see MongoDB\Driver\ReadPreference.
readPreferenceTags	array	Corresponds to the read preference's tagSets parameter. Tag sets allow you to target read operations to specific members of a replica set. For details, see MongoDB\Driver\ReadPreference. Nota: When not specified in the URI string, this option is expressed as an array consistent with the format expected by MongoDB\Driver\ReadPreference::__construct().
replicaSet	string	Specifies the name of the replica set.
retryReads	bool	Specifies whether or not the driver should automatically retry certain read operations that fail due to transient network errors or replica set elections. This functionality requires MongoDB 3.6+. Defaults to true. See the » Retryable Reads Specification for more information.
retryWrites	bool	Specifies whether or not the driver should automatically retry certain write operations that fail due to transient network errors or replica set elections. This functionality requires MongoDB 3.6+. Defaults to true. See » Retryable Writes in the MongoDB manual for more information.
safe	bool	If true, specifies 1 for the default write concern's w parameter. If false, 0 is specified. For details, see MongoDB\Driver\WriteConcern. This option is deprecated and should not be used.
serverSelectionTimeoutMS	int	Specifies how long in milliseconds to block for server selection before throwing an exception. Defaults to 30,000 milliseconds.
serverSelectionTryOnce	bool	When true, instructs the driver to scan the MongoDB deployment exactly once after server selection fails and then either select a server or raise an error. When false, the driver blocks and searches for a server up to the "serverSelectionTimeoutMS" value. Defaults to true.
socketCheckIntervalMS	int	If a socket has not been used recently, the driver must check it via a hello command before using it for any operation. Defaults to 5,000 milliseconds.
socketTimeoutMS	int	The time in milliseconds to attempt a send or receive on a socket before timing out. Defaults to 300,000 milliseconds (i.e. five minutes).
srvMaxHosts	int	The maximum number of SRV results to randomly select when initially populating the seedlist or, during SRV polling, adding new hosts to the topology. Defaults to 0 (i.e. no maximum).
srvServiceName	string	The service name to use for SRV lookup in initial DNS seedlist discovery and SRV polling. Defaults to "mongodb".
ssl	bool	Initiates the connection with TLS/SSL if true. Defaults to false. This option is a deprecated alias for the "tls" URI option.
tls	bool	Initiates the connection with TLS/SSL if true. Defaults to false.
tlsAllowInvalidCertificates	bool	Specifies whether or not the driver should error when the server's TLS certificate is invalid. Defaults to false. Avviso Disabling certificate validation creates a vulnerability.
tlsAllowInvalidHostnames	bool	Specifies whether or not the driver should error when there is a mismatch between the server's hostname and the hostname specified by the TLS certificate. Defaults to false. Avviso Disabling certificate validation creates a vulnerability. Allowing invalid hostnames may expose the driver to a » man-in-the-middle attack.
tlsCAFile	string	Path to file with either a single or bundle of certificate authorities to be considered trusted when making a TLS connection. The system certificate store will be used by default.
tlsCertificateKeyFile	string	Path to the client certificate file or the client private key file; in the case that they both are needed, the files should be concatenated.
tlsCertificateKeyFilePassword	string	Password to decrypt the client private key (i.e. "tlsCertificateKeyFile" URI option) to be used for TLS connections.
tlsDisableCertificateRevocationCheck	bool	If true, the driver will not attempt to check certificate revocation status (e.g. OCSP, CRL). Defaults to false.
tlsDisableOCSPEndpointCheck	bool	If true, the driver will not attempt to contact an OCSP responder endpoint if needed (i.e. an OCSP response is not stapled). Defaults to false.
tlsInsecure	bool	Relax TLS constraints as much as possible. Specifying true for this option has the same effect as specifying true for both the "tlsAllowInvalidCertificates" and "tlsAllowInvalidHostnames" URI options. Defaults to false. Avviso Disabling certificate validation creates a vulnerability. Allowing invalid hostnames may expose the driver to a » man-in-the-middle attack.
username	string	The username for the user being authenticated. This option is useful if the username contains special characters, which would otherwise need to be URL encoded for the connection URI.
w	int|string	Corresponds to the default write concern's w parameter. For details, see MongoDB\Driver\WriteConcern.
wTimeoutMS	int|string	Corresponds to the default write concern's wtimeout parameter. Specifies a time limit, in milliseconds, for the write concern. For details, see MongoDB\Driver\WriteConcern. If specified, wTimeoutMS must be a signed 32-bit integer greater than or equal to zero.
zlibCompressionLevel	int	Specifies the compression level to use for the zlib compressor. This option has no effect if zlib is not included in the "compressors" URI option. See the » Driver Compression Specification for more information.

driverOptions

driverOptions

Option	Type	Description
allow_invalid_hostname	bool	Disables hostname validation if true. Defaults to false. Allowing invalid hostnames may expose the driver to a » man-in-the-middle attack. This option is a deprecated alias for the "tlsAllowInvalidHostnames" URI option.
autoEncryption	array	Provides options to enable automatic client-side field level encryption. Nota: Automatic encryption is an enterprise-only feature that only applies to operations on a collection. Automatic encryption is not supported for operations on a database or view, and operations that are not bypassed will result in error (see » libmongocrypt: Auto Encryption Allow-List). To bypass automatic encryption for all operations, set bypassAutoEncryption to true. Automatic encryption requires the authenticated user to have the » listCollections privilege action. Explicit encryption/decryption and automatic decryption is a community feature. The driver can still automatically decrypt when bypassAutoEncryption is true. The following options are supported: Options for automatic encryption Option Type Description keyVaultClient MongoDB\Driver\Manager The Manager used to route data key queries to a separate MongoDB cluster. By default, the current Manager and cluster is used. keyVaultNamespace string A fully qualified namespace (e.g. "databaseName.collectionName") denoting the collection that contains all data keys used for encryption and decryption. This option is required. kmsProviders array A document containing the configuration for one or more KMS providers, which are used to encrypt data keys. Supported providers include "aws", "azure", "gcp", "kmip", and "local" and at least one must be specified. If an empty document is specified for "aws", "azure", or "gcp", the driver will attempt to configure the provider using » Automatic Credentials. The format for "aws" is as follows: aws: { accessKeyId: <string>, secretAccessKey: <string>, sessionToken: <optional string> } The format for "azure" is as follows: azure: { tenantId: <string>, clientId: <string>, clientSecret: <string>, identityPlatformEndpoint: <optional string> // Defaults to "login.microsoftonline.com" } The format for "gcp" is as follows: gcp: { email: <string>, privateKey: <base64 string>|<MongoDB\BSON\Binary>, endpoint: <optional string> // Defaults to "oauth2.googleapis.com" } The format for "kmip" is as follows: kmip: { endpoint: <string> } The format for "local" is as follows: local: { // 96-byte master key used to encrypt/decrypt data keys key: <base64 string>|<MongoDB\BSON\Binary> } tlsOptions array A document containing the TLS configuration for one or more KMS providers. Supported providers include "aws", "azure", "gcp", and "kmip". All providers support the following options: <provider>: { tlsCaFile: <optional string>, tlsCertificateKeyFile: <optional string>, tlsCertificateKeyFilePassword: <optional string>, tlsDisableOCSPEndpointCheck: <optional bool> } schemaMap array|object Map of collection namespaces to a local JSON schema. This is used to configure automatic encryption. See » Automatic Encryption Rules in the MongoDB manual for more information. It is an error to specify a collection in both schemaMap and encryptedFieldsMap. Nota: Supplying a schemaMap provides more security than relying on JSON schemas obtained from the server. It protects against a malicious server advertising a false JSON schema, which could trick the client into sending unencrypted data that should be encrypted. Nota: Schemas supplied in the schemaMap only apply to configuring automatic encryption for client side encryption. Other validation rules in the JSON schema will not be enforced by the driver and will result in an error. bypassAutoEncryption bool If true, mongocryptd will not be spawned automatically. This is used to disable automatic encryption. Defaults to false. bypassQueryAnalysis bool If true, automatic analysis of outgoing commands will be disabled and mongocryptd will not be spawned automatically. This enables the use case of explicit encryption for querying indexed fields without requiring the enterprise licensed crypt_shared library or mongocryptd process. Defaults to false. encryptedFieldsMap array|object Map of collection namespaces to an encryptedFields document. This is used to configure queryable encryption. See » Field Encryption and Queryability in the MongoDB manual for more information. It is an error to specify a collection in both encryptedFieldsMap and schemaMap. Nota: Supplying an encryptedFieldsMap provides more security than relying on an encryptedFields obtained from the server. It protects against a malicious server advertising a false encryptedFields. extraOptions array The extraOptions relate to the mongocryptd process. The following options are supported: mongocryptdURI (string): URI to connect to an existing mongocryptd process. Defaults to "mongodb://localhost:27020". mongocryptdBypassSpawn (bool): If true, prevent the driver from spawning mongocryptd. Defaults to false. mongocryptdSpawnPath (string): Absolute path to search for mongocryptd binary. Defaults to empty string and consults system paths. mongocryptdSpawnArgs (array): Array of string arguments to pass to mongocryptd when spawning. Defaults to ["--idleShutdownTimeoutSecs=60"]. cryptSharedLibPath (string): Absolute path to crypt_shared shared library. Defaults to empty string and consults system paths. cryptSharedLibRequired (bool): If true, require the driver to load crypt_shared. Defaults to false. See the » Client-Side Encryption Specification for more information. Nota: Automatic encryption is an enterprise only feature that only applies to operations on a collection. Automatic encryption is not supported for operations on a database or view, and operations that are not bypassed will result in error. To bypass automatic encryption for all operations, set bypassAutoEncryption=true in autoEncryption. For more information on allowed operations, see the » Client-Side Encryption Specification.
ca_dir	string	Path to a correctly hashed certificate directory. The system certificate store will be used by default.
ca_file	string	Path to file with either a single or bundle of certificate authorities to be considered trusted when making a TLS connection. The system certificate store will be used by default. This option is a deprecated alias for the "tlsCAFile" URI option.
context	resource	SSL context options to be used as fallbacks if a driver option or its equivalent URI option, if any, is not specified. Note that the extension does not consult the default stream context (i.e. stream_context_get_default()). The following context options are supported: SSL context option fallbacks Driver option Context option (fallback) ca_dir capath ca_file cafile pem_file local_cert pem_pwd passphrase weak_cert_validation allow_self_signed This option is supported for backwards compatibility, but should be considered deprecated.
crl_file	string	Path to a certificate revocation list file.
disableClientPersistence	bool	If true, this Manager will use a new libmongoc client, which will not be persisted or shared with other Manager objects. When this Manager object is freed, its client will be destroyed and any connections will be closed. Defaults to false. Nota: Disabling client persistence is not generally recommended.
driver	array	Allows a higher level library to append its own metadata to the server handshake. By default, the extension submits its own name, version, and platform (i.e. PHP version) in the handshake. Strings can be specified for the "name", "version", and "platform" keys of this array, and will be appended to the respective field(s) in the handshake document. Nota: Handshake information is limited to 512 bytes. The extension will truncate handshake data to fit within this 512-byte string. Higher level libraries are encouraged to keep their own metadata concise.
pem_file	string	Path to a PEM encoded certificate to use for client authentication. This option is a deprecated alias for the "tlsCertificateKeyFile" URI option.
pem_pwd	string	Passphrase for the PEM encoded certificate (if applicable). This option is a deprecated alias for the "tlsCertificateKeyFilePassword" URI option.
serverApi	MongoDB\Driver\ServerApi	This option is used to declare a server API version for the manager. If omitted, no API version is declared.
weak_cert_validation	bool	Disables certificate validation if true. Defaults to false This option is a deprecated alias for the "tlsAllowInvalidCertificates" URI option.
