ne_request_create 3 ne_request_create ne_request_dispatch ne_request_destroy low-level HTTP request handling #include <ne_request.h> ne_request *ne_request_create ne_session *session const char *method const char *path int ne_request_dispatch ne_request *req void ne_request_destroy ne_request *req An HTTP request, represented by the ne_request type, specifies that some operation is to be performed on some resource. The ne_request_create function creates a request object, specifying the operation in the method parameter. The location of the resource is determined by the server in use for the session given by the sess parameter, combined with the path parameter. The path string used must conform to the abs_path definition given in RFC2396, with an optional "?query" part, and must be URI-escaped by the caller (for instance, using ne_path_escape). If the string comes from an untrusted source, failure to perform URI-escaping results in a security vulnerability. To dispatch a request, and process the response, the ne_request_dispatch function can be used. An alternative is to use the (more complex, but more flexible) combination of the ne_begin_request, ne_end_request, and ne_read_response_block functions; see ne_begin_request. To add extra headers in the request, the functions and can be used. To include a message body with the request, one of the functions ne_set_request_body_buffer, , or ne_set_request_body_provider can be used. The return value of ne_request_dispatch indicates merely whether the request was sent and the response read successfully. To discover the result of the operation, , along with any processing of the response headers and message body. A request can only be dispatched once: calling ne_request_dispatch more than once on a single ne_request object produces undefined behaviour. Once all processing associated with the request object is complete, use the ne_request_destroy function to destroy the resources associated with it. Any subsequent use of the request object produces undefined behaviour. The ne_request_create function returns a pointer to a request object (and never &null;). The ne_request_dispatch function returns zero if the request was dispatched successfully, and a non-zero error code otherwise. NE_ERROR Request failed (see session error string) NE_LOOKUP The DNS lookup for the server (or proxy server) failed. NE_AUTH Authentication failed on the server. NE_PROXYAUTH Authentication failed on the proxy server. NE_CONNECT A connection to the server could not be established. NE_TIMEOUT A timeout occurred while waiting for the server to respond. An example of applying a MKCOL operation to the resource at the location http://www.example.com/foo/bar/: ne_session *sess = ne_session_create("http", "www.example.com", 80); ne_request *req = ne_request_create(sess, "MKCOL", "/foo/bar/"); if (ne_request_dispatch(req)) { printf("Request failed: %s\n", ne_get_error(sess)); } ne_request_destroy(req); , , , , .
