## Description

## Details

### struct SoupMessage

    struct SoupMessage {
    	const char         *method;

    	guint               status_code;
    	const char         *reason_phrase;

    	SoupDataBuffer      request;
    	GHashTable         *request_headers;

    	SoupDataBuffer      response;
    	GHashTable         *response_headers;

    	SoupMessageStatus   status;
    };

Represents an HTTP message being sent or received.

const char *`method`; | the HTTP method
guint `status_code`; | the HTTP status code
const char *`reason_phrase`; | the status phrase associated with `status_code`
SoupDataBuffer `request`; | the request buffer
GHashTable *`request_headers`; | the request headers
SoupDataBuffer `response`; | the response buffer
GHashTable *`response_headers`; | the response headers
SoupMessageStatus `status`; | the processing status of the message

### enum SoupMessageStatus

    typedef enum {
    	SOUP_MESSAGE_STATUS_IDLE,
    	SOUP_MESSAGE_STATUS_QUEUED,
            SOUP_MESSAGE_STATUS_CONNECTING,
            SOUP_MESSAGE_STATUS_RUNNING,
    	SOUP_MESSAGE_STATUS_FINISHED
    } SoupMessageStatus;

Enum indicating the lifecycle of a SoupMessage.

`SOUP_MESSAGE_STATUS_IDLE` | The message has not yet been queued.
`SOUP_MESSAGE_STATUS_QUEUED` | The message has been queued, but is waiting for a connection to be available.
`SOUP_MESSAGE_STATUS_CONNECTING` | The message is waiting for a specific connection to finish connecting.
`SOUP_MESSAGE_STATUS_RUNNING` | The message is being processed.
`SOUP_MESSAGE_STATUS_FINISHED` | The message is complete (request and response both processed).

### SOUP_MESSAGE_IS_STARTING()

    #define SOUP_MESSAGE_IS_STARTING(msg) (msg->status == SOUP_MESSAGE_STATUS_QUEUED || msg->status == SOUP_MESSAGE_STATUS_CONNECTING)

Tests if `msg` is in a "starting" state, waiting to be sent. (More commonly used to test if a message has been requeued after its first attempt.)

`msg` : | a SoupMessage
Returns : | `TRUE` if `msg` is waiting to be sent.

### enum SoupTransferEncoding

    typedef enum {
    	SOUP_TRANSFER_UNKNOWN = 0,
    	SOUP_TRANSFER_CHUNKED,
    	SOUP_TRANSFER_CONTENT_LENGTH,
    	SOUP_TRANSFER_BYTERANGES,
    	SOUP_TRANSFER_NONE,
    	SOUP_TRANSFER_EOF
    } SoupTransferEncoding;

How the length of a request or response is to be encoded.

`SOUP_TRANSFER_UNKNOWN` | unknown / error
`SOUP_TRANSFER_CHUNKED` | chunked encoding (currently only supported for response)
`SOUP_TRANSFER_CONTENT_LENGTH` | Content-Length encoding
`SOUP_TRANSFER_BYTERANGES` | multipart/byteranges (Reserved for future use: NOT CURRENTLY IMPLEMENTED)
`SOUP_TRANSFER_NONE` | no body is present (which is not the same as a 0-length body, and only occurs in certain places)
`SOUP_TRANSFER_EOF` | Response body ends when the connection is closed

### enum SoupOwnership

    typedef enum {
    	SOUP_BUFFER_SYSTEM_OWNED = 0,
    	SOUP_BUFFER_USER_OWNED,
    	SOUP_BUFFER_STATIC
    } SoupOwnership;

Used by SoupDataBuffer (and several functions) to indicate the ownership of a buffer.

`SOUP_BUFFER_SYSTEM_OWNED` | The data is owned by soup and it can free it when it is done with it.
`SOUP_BUFFER_USER_OWNED` | The data is owned by the user, who is responsible for freeing it at the right point
`SOUP_BUFFER_STATIC` | The data should not be freed.

### SoupDataBuffer

    typedef struct {
    	SoupOwnership  owner;
    	char          *body;
    	guint          length;
    } SoupDataBuffer;

A data buffer used in several places.

SoupOwnership `owner`; | the ownership of the data
char *`body`; | the data itself
guint `length`; | length of `body`

### SoupMessageCallbackFn ()

    void                (*SoupMessageCallbackFn)            (SoupMessage *req,
                                                             gpointer user_data);

A callback function used by many SoupMessage methods.

`req` : | the SoupMessage in question
`user_data` : | user data

### soup_message_new ()

    SoupMessage*        soup_message_new                    (const char *method,
                                                             const char *uri_string);

Creates a new empty SoupMessage, which will connect to `uri`

`method` : | the HTTP method for the created request
`uri_string` : | the destination endpoint (as a string)
Returns : | the new SoupMessage (or `NULL` if `uri` could not be parsed).

### soup_message_new_from_uri ()

    SoupMessage*        soup_message_new_from_uri           (const char *method,
                                                             const SoupUri *uri);

Creates a new empty SoupMessage, which will connect to `uri`

`method` : | the HTTP method for the created request
`uri` : | the destination endpoint (as a SoupUri)
Returns : | the new SoupMessage

### soup_message_set_request ()

Various flags that can be set on a SoupMessage to alter its behavior.

`SOUP_MESSAGE_NO_REDIRECT` | The session should not follow redirect (3xx) responses received by this message.
`SOUP_MESSAGE_OVERWRITE_CHUNKS` | Rather than building up the response body in `response`, each new chunk should overwrite the previous one. (This can be used if you are connecting to the `got_chunk` signal or have installed a `SOUP_MESSAGE_BODY_CHUNK` handler.
`SOUP_MESSAGE_EXPECT_CONTINUE` | This will cause an "Expect: 100-continue" header to be added to the outgoing request, giving the server the opportunity to reject the message (eg, with a 401 Unauthorized) before the full request body is sent.

### soup_message_set_flags ()

    void                soup_message_set_flags              (SoupMessage *msg,

`msg` : | a SoupMessage
Returns : | the chunk, or `NULL` if there are no chunks left.

### soup_message_is_keepalive ()

    gboolean            soup_message_is_keepalive           (SoupMessage *msg);

Determines whether or not `msg`'s connection can be kept alive for further requests after processing `msg`.

`msg` : | a SoupMessage
Returns : | `TRUE` or `FALSE`.

### soup_message_get_request_encoding ()

    SoupTransferEncoding soup_message_get_request_encoding  (SoupMessage *msg,

Gets `msg`'s request encoding. For an outgoing (client) request, this is only valid after the message has been fully set up (from the library's perspective, that means not until the message has been queued). For an incoming (server) request, this is valid after the request headers have been read and `msg->request_headers` filled in.

`msg` : | a SoupMessage
`content_length` : | a pointer to store the Content-Length in (or `NULL`).
Returns : | the request encoding (which cannot be `SOUP_TRANSFER_UNKNOWN` or `SOUP_TRANSFER_EOF`). If it is `SOUP_TRANSFER_CONTENT_LENGTH`, *`content_length` will be set to the request body's length.

### soup_message_get_response_encoding ()

    SoupTransferEncoding soup_message_get_response_encoding (SoupMessage *msg,
                                                             guint *content_length);

Gets `msg`'s response encoding. For an outgoing (client) request, this is only valid after the response headers have been read and `msg->response_headers` filled in. For an incoming (server) request, this is valid after the server handler has run.

Note that the returned value is the encoding actually used on the wire; this will not agree with the response headers in some cases (eg, a HEAD response may have a Content-Length header, but will still be considered `SOUP_TRANSFER_NONE` by this function).

`msg` : | a SoupMessage
`content_length` : | a pointer to store the Content-Length in (or `NULL`).
Returns : | the response encoding (which will not be `SOUP_TRANSFER_UNKNOWN`). If it is `SOUP_TRANSFER_CONTENT_LENGTH`, *`content_length` will be set to the response body's length.
