详细描述 ¶

QNetworkConfiguration encapsulates a single access point or service network. In most cases a single access point configuration can be mapped to one network interface. However a single network interface may not always map to only one access point configuration. Multiple configurations for the same network device may enable multiple access points. An example device that could exhibit such a configuration might be a Smartphone which allows the user to manage multiple WLAN configurations while the device itself has only one WLAN network device.

QNetworkConfiguration also supports the concept of service networks. This concept allows the grouping of multiple access point configurations into one entity. Such a group is called service network and can be beneficial in cases whereby a network session to a particular destination network is required (e.g. a company network). When using a service network the user doesn’t usually care which one of the connectivity options is chosen (e.g. corporate WLAN or VPN via GPRS) as long as he can reach the company’s target server. Depending on the current position and time some of the access points that make up the service network may not even be available. Furthermore automated access point roaming can be enabled which enables the device to change the network interface configuration dynamically while maintaining the applications connection to the target network. It allows adaption to the changing environment and may enable optimization with regards to cost, speed or other network parameters.

Special configurations of type UserChoice provide a placeholder configuration which is resolved to an actual network configuration by the platform when a session is opened . Not all platforms support the concept of a user choice configuration.

Configuration States ¶

The list of available configurations can be obtained via allConfigurations() . A configuration can have multiple states. The Defined configuration state indicates that the configuration is stored on the device. However the configuration is not yet ready to be activated as e.g. a WLAN may not be available at the current time.

Discovered state implies that the configuration is Defined and the outside conditions are such that the configuration can be used immediately to open a new network session. An example of such an outside condition may be that the Ethernet cable is actually connected to the device or that the WLAN with the specified SSID is in range.

Active state implies that the configuration is Discovered . A configuration in this state is currently being used by an application. The underlying network interface has a valid IP configuration and can transfer IP packets between the device and the target network.

Undefined state indicates that the system has knowledge of possible target networks but cannot actually use that knowledge to connect to it. An example for such a state could be an encrypted WLAN that has been discovered but the user hasn’t actually saved a configuration including the required password which would allow the device to connect to it.

Depending on the type of configuration some states are transient in nature. A GPRS/UMTS connection may almost always be Discovered if the GSM/UMTS network is available. However if the GSM/UMTS network loses the connection the associated configuration may change its state from Discovered to Defined as well. A similar use case might be triggered by WLAN availability. updateConfigurations() can be used to manually trigger updates of states. Note that some platforms do not require such updates as they implicitly change the state once it has been discovered. If the state of a configuration changes all related QNetworkConfiguration instances change their state automatically.

PySide2.QtNetwork.QNetworkConfiguration. Type ¶

This enum describes the type of configuration.

常量	描述
QNetworkConfiguration.InternetAccessPoint	The configuration specifies the details for a single access point. Note that configurations of type may be part of other QNetworkConfigurations of type .
QNetworkConfiguration.ServiceNetwork	The configuration is based on a group of QNetworkConfigurations of type . All group members can reach the same target network. This type of configuration is a mandatory requirement for roaming enabled network sessions. On some platforms this form of configuration may also be called Service Network Access Point (SNAP).
QNetworkConfiguration.UserChoice	The configuration is a placeholder which will be resolved to an actual configuration by the platform when a session is opened. Depending on the platform the selection may generate a popup dialog asking the user for his preferred choice.
QNetworkConfiguration.Invalid	The configuration is invalid.

New in version 4.7.

PySide2.QtNetwork.QNetworkConfiguration. 目的 ¶

Specifies the purpose of the configuration.

常量	描述
QNetworkConfiguration.UnknownPurpose	The configuration doesn’t specify any purpose. This is the default value.
QNetworkConfiguration.PublicPurpose	The configuration can be used for general purpose internet access.
QNetworkConfiguration.PrivatePurpose	The configuration is suitable to access a private network such as an office Intranet.
QNetworkConfiguration.ServiceSpecificPurpose	The configuration can be used for operator specific services (e.g. receiving MMS messages or content streaming).

New in version 4.7.

PySide2.QtNetwork.QNetworkConfiguration. StateFlag ¶

Specifies the configuration states.

常量	描述
QNetworkConfiguration.Undefined	This state is used for transient configurations such as newly discovered WLANs for which the user has not actually created a configuration yet.
QNetworkConfiguration.Defined	Defined configurations are known to the system but are not immediately usable (e.g. a configured WLAN is not within range or the Ethernet cable is currently not plugged into the machine).
QNetworkConfiguration.Discovered	A discovered configuration can be immediately used to create a new `QNetworkSession` . An example of a discovered configuration could be a WLAN which is within in range. If the device moves out of range the discovered flag is dropped. A second example is a GPRS configuration which generally remains discovered for as long as the device has network coverage. A configuration that has this state is also in state . If the configuration is a service network this flag is set if at least one of the underlying access points configurations has the Discovered state.
QNetworkConfiguration.Active	The configuration is currently used by an open network session (see `isOpen()` ). However this does not mean that the current process is the entity that created the open session. It merely indicates that if a new `QNetworkSession` were to be constructed based on this configuration `state()` would return `Connected` . This state implies the state.

New in version 4.7.

PySide2.QtNetwork.QNetworkConfiguration. BearerType ¶

Specifies the type of bearer used by a configuration.

常量	描述
QNetworkConfiguration.BearerUnknown	The type of bearer is unknown or unspecified. The `bearerTypeName()` function may return additional information.
QNetworkConfiguration.BearerEthernet	The configuration is for an Ethernet interfaces.
QNetworkConfiguration.BearerWLAN	The configuration is for a Wireless LAN interface.
QNetworkConfiguration.Bearer2G	The configuration is for a CSD, GPRS, HSCSD, EDGE or cdmaOne interface.
QNetworkConfiguration.Bearer3G	The configuration is for a 3G interface.
QNetworkConfiguration.Bearer4G	The configuration is for a 4G interface.
QNetworkConfiguration.BearerCDMA2000	The configuration is for CDMA interface.
QNetworkConfiguration.BearerWCDMA	The configuration is for W-CDMA/UMTS interface.
QNetworkConfiguration.BearerHSPA	The configuration is for High Speed Packet Access (HSPA) interface.
QNetworkConfiguration.BearerBluetooth	The configuration is for a Bluetooth interface.
QNetworkConfiguration.BearerWiMAX	The configuration is for a WiMAX interface.
QNetworkConfiguration.BearerEVDO	The configuration is for an EVDO (3G) interface.
QNetworkConfiguration.BearerLTE	The configuration is for a LTE (4G) interface.

PySide2.QtNetwork.QNetworkConfiguration. bearerType ( ) ¶

返回类型: BearerType

Returns the type of bearer used by this network configuration.

If the bearer type is unknown the bearerTypeName() function can be used to retrieve a textural type name for the bearer.

An invalid network configuration always returns the BearerUnknown 值。
