typedef struct {
int year;

int day;
int hour;
int minute;
int second;
gboolean utc;
int offset;
} SoupDate;
A date and time. The date is assumed to be in the (proleptic)
Gregorian calendar. The time is in UTC if utc is TRUE. Otherwise,
the time is a local time, and offset gives the offset from UTC in
minutes (such that adding offset to the time would give the
correct UTC time). If utc is FALSE and offset is 0, then the
SoupDate represents a "floating" time with no associated timezone
information.
typedef enum {
SOUP_DATE_HTTP = 1,
SOUP_DATE_COOKIE,
SOUP_DATE_RFC2822,
SOUP_DATE_ISO8601_COMPACT,
SOUP_DATE_ISO8601_FULL,
SOUP_DATE_ISO8601 = SOUP_DATE_ISO8601_FULL,
SOUP_DATE_ISO8601_XMLRPC
} SoupDateFormat;
Date formats that soup_date_to_string() can use.
SOUP_DATE_HTTP and SOUP_DATE_COOKIE always coerce the time to
UTC. SOUP_DATE_ISO8601_XMLRPC uses the time as given, ignoring the
offset completely. SOUP_DATE_RFC2822 and the other ISO 8601
variants use the local time, appending the offset information if
available.
This enum may be extended with more values in future releases.

Returns : |
a new SoupDate |
SoupDate * soup_date_new_from_string (const char *date_string);
Parses date_string and tries to extract a date from it. This
recognizes all of the "HTTP-date" formats from RFC 2616, all ISO
8601 formats containing both a time and a date, RFC 2822 dates,
and reasonable approximations thereof. (Eg, it is lenient about
whitespace, leading "0"s, etc.)
|
the date in some plausible format |
Returns : |
a new SoupDate, or NULL if date_string could not
be parsed.
|
SoupDate * soup_date_new_from_time_t (time_t when);
Creates a SoupDate corresponding to when
|
a time_t |
Returns : |
a new SoupDate |
SoupDate * soup_date_new_from_now (int offset_seconds);
Creates a SoupDate representing a time offset_seconds after the
current time (or before it, if offset_seconds is negative). If
offset_seconds is 0, returns the current time.
|
offset from current time |
Returns : |
a new SoupDate |
char * soup_date_to_string (SoupDate *date,SoupDateFormat format);
Converts date to a string in the format described by format.
|
a SoupDate |
|
the format to generate the date in |
Returns : |
date as a string
|
time_t soup_date_to_time_t (SoupDate *date);
Converts date to a time_t.
If date is not representable as a time_t, it will be clamped into
range. (In particular, some HTTP cookies have expiration dates
after "Y2.038k" (2038-01-19T03:14:07Z).)
|
a SoupDate |
Returns : |
date as a time_t
|
void soup_date_to_timeval (SoupDate *date,GTimeVal *time);
Converts date to a GTimeVal.

Since 2.24
gboolean soup_date_is_past (SoupDate *date);
Determines if date is in the past.
|
a SoupDate |
Returns : |
TRUE if date is in the past
|

guint soup_headers_parse_request (const char *str,int len,SoupMessageHeaders *req_headers,char **req_method,char **req_path,SoupHTTPVersion *ver);
Parses the headers of an HTTP request in str and stores the
results in req_method, req_path, ver, and req_headers.
Beware that req_headers may be modified even on failure.
|
the header string (including the trailing blank line) |
|
length of str up to (but not including) the terminating blank line.
|
|
SoupMessageHeaders to store the header values in |
|
if non-NULL, will be filled in with the
request method. [out][allow-none]
|
|
if non-NULL, will be filled in with the
request path. [out][allow-none]
|
|
if non-NULL, will be filled in with the HTTP
version. [out][allow-none]
|
Returns : |
SOUP_STATUS_OK if the headers could be parsed, or an
HTTP error to be returned to the client if they could not be.
|
gboolean soup_headers_parse_response (const char *str,int len,SoupMessageHeaders *headers,SoupHTTPVersion *ver,guint *status_code,char **reason_phrase);
Parses the headers of an HTTP response in str and stores the
results in ver, status_code, reason_phrase, and headers.
Beware that headers may be modified even on failure.
|
the header string (including the trailing blank line) |
|
length of str up to (but not including) the terminating blank line.
|
|
SoupMessageheaders to store the header values in |
|
if non-NULL, will be filled in with the HTTP
version. [out][allow-none]
|
|

success or failure. |
gboolean soup_headers_parse_status_line (const char *status_line,SoupHTTPVersion *ver,guint *status_code,char **reason_phrase);
Parses the HTTP Status-Line string in status_line into ver,
status_code, and reason_phrase. status_line must be terminated by
either "\0" or "\r\n".
|
an HTTP Status-Line |
|
if non-NULL, will be filled in with the HTTP
version. [out][allow-none]
|
|
if non-NULL, will be filled in with
the status code. [out][allow-none]
|
|
if non-NULL, will be filled in with
the reason phrase. [out][allow-none]
|
Returns : |
TRUE if status_line was parsed successfully.
|
gboolean soup_headers_parse (const char *str,int len,SoupMessageHeaders *dest);
Parses the headers of an HTTP request or response in str and
stores the results in dest. Beware that dest may be modified even
on failure.
This is a low-level method; normally you would use
soup_headers_parse_request() or soup_headers_parse_response().
|
the header string (including the Request-Line or Status-Line, and the trailing blank line) |
|
length of str up to (but not including) the terminating blank line.
|
|
SoupMessageHeaders to store the header values in |
Returns : |
success or failure |
Since 2.26
GSList * soup_header_parse_list (const char *header);
Parses a header whose content is described by RFC2616 as "something", where "something" does not itself contain commas, except as part of quoted-strings.
|
a header value |
Returns : |
a GSList of list elements, as allocated strings. [transfer full] |
GSList * soup_header_parse_quality_list (const char *header,GSList **unacceptable);
Parses a header whose content is a list of items with optional "qvalue"s (eg, Accept, Accept-Charset, Accept-Encoding, Accept-Language, TE).
If unacceptable is not NULL, then on return, it will contain the
items with qvalue 0. Either way, those items will be removed from
the main list.
|
a header value |
|
on return, will contain a list of unacceptable values. [out][allow-none][transfer full] |
Returns : |
a GSList of acceptable values (as allocated strings), highest-qvalue first. [transfer full] |
void soup_header_free_list (GSList *list);
Frees list.
|
a GSList returned from soup_header_parse_list() or
soup_header_parse_quality_list()
|
gboolean soup_header_contains (const char *header,const char *token);
Parses header to see if it contains the token token (matched
case-insensitively). Note that this can't be used with lists
that have qvalues.
|
An HTTP header suitable for parsing with
soup_header_parse_list()
|
|
a token |
Returns : |
whether or not header contains token
|
GHashTable * soup_header_parse_param_list (const char *header);
Parses a header which is a comma-delimited list of something like:
token [ "=" ( token | quoted-string ) ].
Tokens that don't have an associated value will still be added to
the resulting hash table, but with a NULL value.
This also handles RFC2231 encoding (which in HTTP is mostly used for giving UTF8-encoded filenames in the Content-Disposition header).
|
a header value |
Returns : |
a
GHashTable of list elements, which can be freed with
soup_header_free_param_list(). [element-type utf8 utf8][transfer full utf8 utf8]
|
GHashTable * soup_header_parse_semi_param_list (const char *header);
Parses a header which is a semicolon-delimited list of something
like: token [ "=" ( token | quoted-string ) ].
Tokens that don't have an associated value will still be added to
the resulting hash table, but with a NULL value.
This also handles RFC2231 encoding (which in HTTP is mostly used for giving UTF8-encoded filenames in the Content-Disposition header).
|
a header value |
Returns : |
a
GHashTable of list elements, which can be freed with
soup_header_free_param_list(). [element-type utf8 utf8][transfer full utf8 utf8]
|
Since 2.24
void soup_header_free_param_list (GHashTable *param_list);
Frees param_list.
|
a GHashTable returned from soup_header_parse_param_list()
or soup_header_parse_semi_param_list(). [element-type utf8 utf8]
|
void soup_header_g_string_append_param (GString *string,const char *name,const char *value);
Appends something like to name=valuestring,
taking care to quote value if needed, and if so, to escape any
quotes or backslashes in value.
Alternatively, if value is a non-ASCII UTF-8 string, it will be
appended using RFC2231 syntax. Although in theory this is supposed
to work anywhere in HTTP that uses this style of parameter, in
reality, it can only be used portably with the Content-Disposition
"filename" parameter.
If value is NULL, this will just append name to string.
|
a GString being used to construct an HTTP header value |
|
a parameter name |
|
a parameter value, or NULL
|
Since 2.26
gboolean soup_str_case_equal (gconstpointer v1,gconstpointer v2);
Compares v1 and v2 in a case-insensitive manner
|
an ASCII string |
|
another ASCII string |
Returns : |
TRUE if they are equal (modulo case)
|
guint soup_str_case_hash (gconstpointer key);
Hashes key in a case-insensitive manner.
|
ASCII string to hash |
Returns : |
the hash code. |
GSource * soup_add_completion (GMainContext *async_context,GSourceFunc function,gpointer data);
Adds function to be executed from inside async_context with the
default priority. Use this when you want to complete an action in
async_context's main loop, as soon as possible.
|
the GMainContext to dispatch the I/O
watch in, or NULL for the default context. [allow-none]
|
|
the callback to invoke |
|
user data to pass to function
|
Returns : |
a GSource, which can be removed from async_context
with g_source_destroy().
|
Since 2.24
GSource * soup_add_idle (GMainContext *async_context,GSourceFunc function,gpointer data);
Adds an idle event as with g_idle_add(), but using the given
async_context.
If you want function to run "right away", use
soup_add_completion(), since that sets a higher priority on the
GSource than soup_add_idle() does.
|
the GMainContext to dispatch the I/O
watch in, or NULL for the default context. [allow-none]
|
|
the callback to invoke at idle time |
|
user data to pass to function
|
Returns : |
a GSource, which can be removed from async_context
with g_source_destroy().
|
GSource * soup_add_io_watch (GMainContext *async_context,GIOChannel *chan,GIOCondition condition,GIOFunc function,gpointer data);
Adds an I/O watch as with g_io_add_watch(), but using the given
async_context.
|
the GMainContext to dispatch the I/O
watch in, or NULL for the default context. [allow-none]
|

the GIOChannel to watch |
|
the condition to watch for |
|
the callback to invoke when condition occurs
|
|
user data to pass to function

Adds a timeout as with g_timeout_add(), but using the given
async_context.
|
the GMainContext to dispatch the I/O
watch in, or NULL for the default context. [allow-none]
|
|
the timeout interval, in milliseconds |
|
the callback to invoke at timeout time |
|
user data to pass to function
|
Returns : |
a GSource, which can be removed from async_context
with g_source_destroy().
