@Generated("org.javagi.JavaGI")
public final class ServerMessage
extends GObject

An HTTP server request and response pair.

A ServerMessage represents an HTTP message that is being sent or received on a Server.

Server will create ServerMessages automatically for incoming requests, which your application will receive via handlers.

Note that libsoup's terminology here does not quite match the HTTP specification: in RFC 2616, an "HTTP-message" is either a Request, or a Response. In libsoup, a ServerMessage combines both the request and the response.

Constructor Details

ServerMessage

public ServerMessage(MemorySegment address)

Create a ServerMessage instance for the provided memory address.

Parameters:

address - the memory address of the native object

ServerMessage

public ServerMessage()

Create a new ServerMessage.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ServerMessage class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected ServerMessage asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class GObject

Returns:

the instance as if it were its parent type

getHttpVersion

public HTTPVersion getHttpVersion()

Get the HTTP version of msg.

Returns:

a SoupHTTPVersion.

getLocalAddress

public @Nullable SocketAddress getLocalAddress()

Retrieves the SocketAddress associated with the local end of a connection.

Returns:

the GSocketAddress associated with the local end of a connection, it may be null if you used Server.acceptIostream(IOStream, SocketAddress, SocketAddress).

getMethod

public String getMethod()

Get the HTTP method of msg.

Returns:

the HTTP method.

getReasonPhrase

public @Nullable String getReasonPhrase()

Get the HTTP reason phrase of msg.

Returns:

the reason phrase.

getRemoteAddress

public @Nullable SocketAddress getRemoteAddress()

Retrieves the SocketAddress associated with the remote end of a connection.

Returns:

the GSocketAddress associated with the remote end of a connection, it may be null if you used Server.acceptIostream(IOStream, SocketAddress, SocketAddress).

getRemoteHost

public @Nullable String getRemoteHost()

Retrieves the IP address associated with the remote end of a connection.

Returns:

the IP address associated with the remote end of a connection, it may be null if you used Server.acceptIostream(IOStream, SocketAddress, SocketAddress).

public MessageBody getRequestBody()

Get the request body of msg.

Returns:

a SoupMessageBody.

getRequestHeaders

public MessageHeaders getRequestHeaders()

Get the request headers of msg.

Get the response headers of msg.

Returns:

a SoupMessageHeaders with the response headers.

getSocket

public @Nullable Socket getSocket()

Retrieves the Socket that this ServerMessage is associated with.

If you are using this method to observe when multiple requests are made on the same persistent HTTP connection (eg, as the ntlm-test test program does), you will need to pay attention to socket destruction as well (eg, by using weak references), so that you do not get fooled when the allocator reuses the memory address of a previously-destroyed socket to represent a new socket.

Returns:

the GSocket that this ServerMessage is associated with, null if you used Server.acceptIostream(IOStream, SocketAddress, SocketAddress).

getStatus

public int getStatus()

Get the HTTP status code of msg.

Returns:

the HTTP status code.

getTlsPeerCertificate

public @Nullable TlsCertificate getTlsPeerCertificate()

Gets the peer's GTlsCertificate associated with msg's connection. Note that this is not set yet during the emission of SoupServerMessage::accept-certificate signal.

Returns:

msg's TLS peer certificate, or null if msg's connection is not SSL.

Since:

3.2

getTlsPeerCertificateErrors

public Set<TlsCertificateFlags> getTlsPeerCertificateErrors()

Gets the errors associated with validating msg's TLS peer certificate. Note that this is not set yet during the emission of SoupServerMessage::accept-certificate signal.

Returns:

a GTlsCertificateFlags with msg's TLS peer certificate errors.

Since:

3.2

Get msg's URI.

Returns:

a GUri

Gets if this ServerMessage represents an OPTIONS message with the path *.

Returns:

pause

public void pause()

Pauses I/O on msg.

This can be used when you need to return from the server handler without having the full response ready yet. Use unpause() to resume I/O.

Since:

3.2

setHttpVersion

public void setHttpVersion(HTTPVersion version)

Set the HTTP version of msg.

Parameters:

version - a SoupHTTPVersion

setRedirect

public void setRedirect(int statusCode,
 String redirectUri)

Sets msg's status_code to statusCode and adds a Location header pointing to redirectUri. Use this from a Server when you want to redirect the client to another URI.

redirectUri can be a relative URI, in which case it is interpreted relative to msg's current URI. In particular, if redirectUri is just a path, it will replace the path and query of msg's URI.

Parameters:

statusCode - a 3xx status code

redirectUri - the URI to redirect this ServerMessage to

setResponse

public void setResponse(@Nullable String contentType,
 MemoryUse respUse,
 @Nullable byte @Nullable [] respBody)

Convenience function to set the response body of a ServerMessage. If contentType is null, the response body must be empty as well.

Parameters:

contentType - MIME Content-Type of the body

respUse - a SoupMemoryUse describing how to handle respBody

respBody - a data buffer containing the body of the message response.

setStatus

public void setStatus(int statusCode,
 @Nullable String reasonPhrase)

Sets msg's status code to statusCode.

If statusCode is a known value and reasonPhrase is null, the reason_phrase will be set automatically.

Parameters:

statusCode - an HTTP status code

reasonPhrase - a reason phrase

stealConnection

public IOStream stealConnection()

"Steals" the HTTP connection associated with this ServerMessage from its Server. This happens immediately, regardless of the current state of the connection; if the response to this ServerMessage has not yet finished being sent, then it will be discarded; you can steal the connection from a ServerMessage::wrote-informational or ServerMessage::wrote-body signal handler if you need to wait for part or all of the response to be sent.

Note that when calling this function from C, this ServerMessage will most likely be freed as a side effect.

Returns:

the GIOStream formerly associated with this ServerMessage (or null if this ServerMessage was no longer associated with a connection). No guarantees are made about what kind of GIOStream is returned.

unpause

public void unpause()

Resumes I/O on msg.

Use this to resume after calling pause(), or after adding a new chunk to a chunked response. I/O won't actually resume until you return to the main loop.

Since:

3.2
