char* soup_xmlrpc_build_method_call (const char *method_name,
GValue *params,
int n_params);
This creates an XML-RPC methodCall and returns it as a string.
This is the low-level method that soup_xmlrpc_request_new() and
soup_xmlrpc_call() are built on.
params is an array of GValue representing the parameters to
method. (It is *not* a GValueArray, although if you have a
GValueArray, you can just pass its values and n_values fields.)
The correspondence between glib types and XML-RPC types is:
int: int (G_TYPE_INT)
boolean: gboolean (G_TYPE_BOOLEAN)
string: char* (G_TYPE_STRING)
double: double (G_TYPE_DOUBLE)
datetime.iso8601: SoupDate (SOUP_TYPE_DATE)
base64: GByteArray (SOUP_TYPE_BYTE_ARRAY)
struct: GHashTable (G_TYPE_HASH_TABLE)
array: GValueArray (G_TYPE_VALUE_ARRAY)
For structs, use a GHashTable that maps strings to GValue;
soup_value_hash_new() and related methods can help with this.
|
the name of the XML-RPC method |
|
arguments to method
|
|
length of params
|
Returns : |
the text of the methodCall, or NULL on error
|
SoupMessage* soup_xmlrpc_request_new (const char *uri, const char *method_name, ...);
Creates an XML-RPC methodCall and returns a SoupMessage, ready to send, for that method call.
The parameters are passed as type/value pairs; ie, first a GType,
and then a value of the appropriate type, finally terminated by
G_TYPE_INVALID.
|
URI of the XML-RPC service |
|
the name of the XML-RPC method to invoke at uri
|
|
parameters for method
|
Returns : |
a SoupMessage encoding the indicated XML-RPC request. |
gboolean soup_xmlrpc_parse_method_response (const char *method_response, int length, GValue *value, GError **error);
Parses method_response and returns the return value in value. If
method_response is a fault, value will be unchanged, and error
will be set to an error of type SOUP_XMLRPC_FAULT, with the error
code containing the fault code, and the error message containing
the fault string. (If method_response cannot be parsed at all,
soup_xmlrpc_parse_method_response() will return FALSE, but error
will be unset.)
|
the XML-RPC methodResponse string |
|
the length of method_response, or -1 if it is NUL-terminated
|
|
on return, the return value from method_call
|
|
error return value |
Returns : |
TRUE if a return value was parsed, FALSE if the
response could not be parsed, or contained a fault.
|
gboolean soup_xmlrpc_extract_method_response (const char *method_response, int length, GError **error, GType type, ...);
Parses method_response and extracts the return value into
a variable of the correct type.
If method_response is a fault, the return value will be unset,
and error will be set to an error of type SOUP_XMLRPC_FAULT, with
the error code containing the fault code, and the error message
containing the fault string. (If method_response cannot be parsed
at all, soup_xmlrpc_extract_method_response() will return FALSE,
but error will be unset.)
|
the XML-RPC methodResponse string |
|
the length of method_response, or -1 if it is NUL-terminated
|
|
error return value |
|
the expected type of the return value |
|
location for return value |
Returns : |
TRUE if a return value was parsed, FALSE if the
response was of the wrong type, or contained a fault.
|
gboolean soup_xmlrpc_parse_method_call (const char *method_call, int length, char **method_name, GValueArray **params);
Parses method_call to get the name and parameters, and returns the
parameter values in a GValueArray; see also
soup_xmlrpc_extract_method_call(), which is more convenient if you
know in advance what the types of the parameters will be.
|
the XML-RPC methodCall string |
|
the length of method_call, or -1 if it is NUL-terminated
|
|
on return, the methodName from method_call
|
|
on return, the parameters from method_call
|
Returns : |
success or failure. |
gboolean soup_xmlrpc_extract_method_call (const char *method_call, int length, char **method_name, ...);
Parses method_call to get the name and parameters, and puts
the parameters into variables of the appropriate types.
The parameters are handled similarly to
soup_xmlrpc_build_method_call, with pairs of types and values,
terminated by G_TYPE_INVALID, except that values are pointers to
variables of the indicated type, rather than values of the type.
See also soup_xmlrpc_parse_method_call(), which can be used if
you don't know the types of the parameters.
|
the XML-RPC methodCall string |
|
the length of method_call, or -1 if it is NUL-terminated
|
|
on return, the methodName from method_call
|
|
return types and locations for parameters |
Returns : |
success or failure. |
char* soup_xmlrpc_build_method_response (GValue *value);
This creates a (successful) XML-RPC methodResponse and returns it
as a string. To create a fault response, use
soup_xmlrpc_build_fault().
The glib type to XML-RPC type mapping is as with
soup_xmlrpc_build_method_call(), qv.
|
the return value |
Returns : |
the text of the methodResponse, or NULL on error
|
char* soup_xmlrpc_build_fault (int fault_code,
const char *fault_format,
...);
This creates an XML-RPC fault response and returns it as a string.
(To create a successful response, use
soup_xmlrpc_build_method_response().)
|
the fault code |
|
a printf()-style format string
|
|
the parameters to fault_format
|
Returns : |
the text of the fault |
void soup_xmlrpc_set_response (SoupMessage *msg, GType type, ...);
Sets the status code and response body of msg to indicate a
successful XML-RPC call, with a return value given by type and the
following varargs argument, of the type indicated by type.
|
an XML-RPC request |
|
the type of the response value |
|
the response value |
void soup_xmlrpc_set_fault (SoupMessage *msg, int fault_code, const char *fault_format, ...);
Sets the status code and response body of msg to indicate an
unsuccessful XML-RPC call, with the error described by fault_code
and fault_format.
|
an XML-RPC request |
|
the fault code |
|
a printf()-style format string
|
|
the parameters to fault_format
|
typedef enum {
SOUP_XMLRPC_ERROR_ARGUMENTS,
SOUP_XMLRPC_ERROR_RETVAL
} SoupXMLRPCError;
