GI.Soup.Objects.Session

Soup session state object.

Session is the object that controls client-side HTTP. A Session encapsulates all of the state that libsoup is keeping on behalf of your program; cached HTTP connections, authentication information, etc. It also keeps track of various global options and features that you are using.

Most applications will only need a single Session; the primary reason you might need multiple sessions is if you need to have multiple independent authentication contexts. (Eg, you are connecting to a server and authenticating as two different users at different times; the easiest way to ensure that each [classmessage] is sent with the authentication information you intended is to use one session for the first user, and a second session for the other user.)

Additional Session functionality is provided by [ifacesessionFeature] objects, which can be added to a session with [methodsession.add_feature] or [methodsession.add_feature_by_type] For example, [classlogger] provides support for logging HTTP traffic, [classcontentDecoder] provides support for compressed response handling, and [classcontentSniffer] provides support for HTML5-style response body content sniffing. Additionally, subtypes of [classauth] can be added as features, to add support for additional authentication types.

All SoupSessions are created with a [classauthManager], and support for SOUP_TYPE_AUTH_BASIC and SOUP_TYPE_AUTH_DIGEST. Additionally, sessions using the plain Session class (rather than one of its deprecated subtypes) have a [classcontentDecoder] by default.

Note that all async methods will invoke their callbacks on the thread-default context at the time of the function call.

Arguments

:: (HasCallStack, MonadIO m, IsSession a)

=> a

session: the session

-> m ()

Cancels all pending requests in session and closes all idle persistent connections.

addFeature

sessionAddFeature

Arguments

:: (HasCallStack, MonadIO m, IsSession a, IsSessionFeature b)

=> a

session: a Session

-> b

feature: an object that implements SessionFeature

-> m ()

Adds feature's functionality to session. You cannot add multiple features of the same [aliasgLib.Type] to a session.

See the main Session documentation for information on what features are present in sessions by default.

addFeatureByType

sessionAddFeatureByType

Arguments

:: (HasCallStack, MonadIO m, IsSession a)

=> a

session: a Session

-> GType

featureType: a GType

-> m ()

If featureType is the type of a class that implements [ifacesessionFeature], this creates a new feature of that type and adds it to session as with [methodsession.add_feature]. You can use this when you don't need to customize the new feature in any way. Adding multiple features of the same featureType is not allowed.

If featureType is not a [ifacesessionFeature] type, this gives each existing feature on session the chance to accept featureType as a "subfeature". This can be used to add new [classauth] types, for instance.

See the main Session documentation for information on what features are present in sessions by default.

sessionSend

Arguments

:: (HasCallStack, MonadIO m, IsSession a, IsMessage b, IsCancellable c)

-> b

msg: a Message

-> Maybe c

cancellable: a Cancellable

-> m InputStream

Returns: a InputStream for reading the response body, or Nothing on error. (Can throw GError)

Synchronously sends msg and waits for the beginning of a response.

On success, a InputStream will be returned which you can use to read the response body. ("Success" here means only that an HTTP response was received and understood; it does not necessarily mean that a 2xx class status code was received.)

If non-Nothing, cancellable can be used to cancel the request; [methodsession.send] will return a IOErrorEnumCancelled error. Note that with requests that have side effects (eg, POST, PUT, DELETE) it is possible that you might cancel the request after the server acts on it, but before it returns a response, leaving the remote resource in an unknown state.

If msg is requeued due to a redirect or authentication, the initial (3xx/401/407) response body will be suppressed, and [methodsession.send] will only return once a final response has been received.

Properties

acceptLanguage

If non-Nothing, the value to use for the "Accept-Language" header on [classmessage]s sent from this session.

Setting this will disable [propertysession:accept-language-auto].

constructSessionAcceptLanguage :: (IsSession o, MonadIO m) => Text -> m (GValueConstruct o)

set session [ #acceptLanguage := value ]

acceptLanguageAuto

If True, Session will automatically set the string for the "Accept-Language" header on every [classmessage] sent, based on the return value of getLanguageNames.

Setting this will override any previous value of [propertysession:accept-language].

constructSessionAcceptLanguageAuto :: (IsSession o, MonadIO m) => Bool -> m (GValueConstruct o)

set session [ #acceptLanguageAuto := value ]

idleTimeout

Connection lifetime (in seconds) when idle. Any connection left idle longer than this will be closed.

Although you can change this property at any time, it will only affect newly-created connections, not currently-open ones. You can call [methodsession.abort] after setting this if you want to ensure that all future connections will have this timeout value.

constructSessionIdleTimeout :: (IsSession o, MonadIO m) => Word32 -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “idle-timeout” property. This is rarely needed directly, but it is used by new.

Get the value of the “max-conns-per-host” property. When overloading is enabled, this is equivalent to

get session #maxConnsPerHost

proxyResolver

A ProxyResolver to use with this session.

If no proxy resolver is set, then the default proxy resolver will be used. See [funcgio.ProxyResolver.get_default]. You can set it to Nothing if you don't want to use proxies, or set it to your own ProxyResolver if you want to control what proxies get used.

clearSessionProxyResolver :: (MonadIO m, IsSession o) => o -> m ()

get session #proxyResolver

setSessionProxyResolver :: (MonadIO m, IsSession o, IsProxyResolver a) => o -> a -> m ()

Set the value of the “proxy-resolver” property. When overloading is enabled, this is equivalent to

set session [ #proxyResolver := value ]

remoteConnectable

Sets a socket to make outgoing connections on. This will override the default behaviour of opening TCP/IP sockets to the hosts specified in the URIs.

This function is not required for common HTTP usage, but only when connecting to a HTTP service that is not using standard TCP/IP sockets. An example of this is a local service that uses HTTP over UNIX-domain sockets, in that case a UnixSocketAddress can be passed to this function.

constructSessionRemoteConnectable :: (IsSession o, MonadIO m, IsSocketConnectable a) => a -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “remote-connectable” property. This is rarely needed directly, but it is used by new.

Get the value of the “remote-connectable” property. When overloading is enabled, this is equivalent to

get session #remoteConnectable

timeout

The timeout (in seconds) for socket I/O operations (including connecting to a server, and waiting for a reply to an HTTP request).

Although you can change this property at any time, it will only affect newly-created connections, not currently-open ones. You can call [methodsession.abort] after setting this if you want to ensure that all future connections will have this timeout value.

Not to be confused with [propertysession:idle-timeout] (which is the length of time that idle persistent connections will be kept open).

constructSessionTimeout :: (IsSession o, MonadIO m) => Word32 -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “timeout” property. This is rarely needed directly, but it is used by new.

getSessionTimeout :: (MonadIO m, IsSession o) => o -> m Word32

Get the value of the “timeout” property. When overloading is enabled, this is equivalent to

get session #timeout

setSessionTimeout :: (MonadIO m, IsSession o) => o -> Word32 -> m ()

Set the value of the “timeout” property. When overloading is enabled, this is equivalent to

set session [ #timeout := value ]

tlsDatabase

Sets the TlsDatabase to use for validating SSL/TLS certificates.

If no certificate database is set, then the default database will be used. See tlsBackendGetDefaultDatabase.

clearSessionTlsDatabase :: (MonadIO m, IsSession o) => o -> m ()

Set the value of the “tls-database” property to Nothing. When overloading is enabled, this is equivalent to

clear #tlsDatabase

constructSessionTlsDatabase :: (IsSession o, MonadIO m, IsTlsDatabase a) => a -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “tls-database” property. This is rarely needed directly, but it is used by new.

getSessionTlsDatabase :: (MonadIO m, IsSession o) => o -> m (Maybe TlsDatabase)

Get the value of the “tls-database” property. When overloading is enabled, this is equivalent to

get session #tlsDatabase

setSessionTlsDatabase :: (MonadIO m, IsSession o, IsTlsDatabase a) => o -> a -> m ()

Set the value of the “tls-database” property. When overloading is enabled, this is equivalent to

set session [ #tlsDatabase := value ]

tlsInteraction

A TlsInteraction object that will be passed on to any TlsConnections created by the session.

This can be used to provide client-side certificates, for example.

clearSessionTlsInteraction :: (MonadIO m, IsSession o) => o -> m ()

Set the value of the “tls-interaction” property to Nothing. When overloading is enabled, this is equivalent to

clear #tlsInteraction

constructSessionTlsInteraction :: (IsSession o, MonadIO m, IsTlsInteraction a) => a -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “tls-interaction” property. This is rarely needed directly, but it is used by new.

getSessionTlsInteraction :: (MonadIO m, IsSession o) => o -> m (Maybe TlsInteraction)

Get the value of the “tls-interaction” property. When overloading is enabled, this is equivalent to

get session #tlsInteraction

setSessionTlsInteraction :: (MonadIO m, IsSession o, IsTlsInteraction a) => o -> a -> m ()

Set the value of the “tls-interaction” property. When overloading is enabled, this is equivalent to

set session [ #tlsInteraction := value ]

userAgent

User-Agent string.

If non-Nothing, the value to use for the "User-Agent" header on [classmessage]s sent from this session.

RFC 2616 says: "The User-Agent request-header field contains information about the user agent originating the request. This is for statistical purposes, the tracing of protocol violations, and automated recognition of user agents for the sake of tailoring responses to avoid particular user agent limitations. User agents SHOULD include this field with requests."

The User-Agent header contains a list of one or more product tokens, separated by whitespace, with the most significant product token coming first. The tokens must be brief, ASCII, and mostly alphanumeric (although "-", "_", and "." are also allowed), and may optionally include a "/" followed by a version string. You may also put comments, enclosed in parentheses, between or after the tokens.

If you set a [propertysession:user-agent] property that has trailing whitespace, Session will append its own product token (eg, libsoup/2.3.2) to the end of the header for you.

constructSessionUserAgent :: (IsSession o, MonadIO m) => Text -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “user-agent” property. This is rarely needed directly, but it is used by new.

getSessionUserAgent :: (MonadIO m, IsSession o) => o -> m (Maybe Text)

Get the value of the “user-agent” property. When overloading is enabled, this is equivalent to

get session #userAgent

setSessionUserAgent :: (MonadIO m, IsSession o) => o -> Text -> m ()

Set the value of the “user-agent” property. When overloading is enabled, this is equivalent to

set session [ #userAgent := value ]

Signals

requestQueued

type SessionRequestQueuedCallback

Arguments

 = Message

msg: the request that was queued

-> IO ()

Emitted when a request is queued on session.

When sending a request, first signalsession[requestQueued] is emitted, indicating that the session has become aware of the request.

After a connection is available to send the request various [classmessage] signals are emitted as the message is processed. If the message is requeued, it will emit signalmessage[restarted], which will then be followed by other [classmessage] signals when the message is re-sent.

Eventually, the message will emit signalmessage[finished]. Normally, this signals the completion of message processing. However, it is possible that the application will requeue the message from the "finished" handler. In that case the process will loop back.

Eventually, a message will reach "finished" and not be requeued. At that point, the session will emit signalsession[requestUnqueued] to indicate that it is done with the message.

To sum up: signalsession[requestQueued] and signalsession[requestUnqueued] are guaranteed to be emitted exactly once, but signalmessage[finished] (and all of the other [classmessage] signals) may be invoked multiple times for a given message.

afterSessionRequestQueued :: (IsSession a, MonadIO m) => a -> ((?self :: a) => SessionRequestQueuedCallback) -> m SignalHandlerId

Connect a signal handler for the requestQueued signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after session #requestQueued callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onSessionRequestQueued :: (IsSession a, MonadIO m) => a -> ((?self :: a) => SessionRequestQueuedCallback) -> m SignalHandlerId

Connect a signal handler for the requestQueued signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on session #requestQueued callback

requestUnqueued

type SessionRequestUnqueuedCallback

Arguments

 = Message

msg: the request that was unqueued

-> IO ()

Emitted when a request is removed from session's queue, indicating that session is done with it.

See signalsession[requestQueued] for a detailed description of the message lifecycle within a session.

afterSessionRequestUnqueued :: (IsSession a, MonadIO m) => a -> ((?self :: a) => SessionRequestUnqueuedCallback) -> m SignalHandlerId

Connect a signal handler for the requestUnqueued signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after session #requestUnqueued callback

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onSessionRequestUnqueued :: (IsSession a, MonadIO m) => a -> ((?self :: a) => SessionRequestUnqueuedCallback) -> m SignalHandlerId

Connect a signal handler for the requestUnqueued signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on session #requestUnqueued callback
