NE_REQUEST_CREATE

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 ne_add_request_header and ne_print_request_header can be used. To include a message body with the request, one of the functions ne_set_request_body_buffer, ne_set_request_body_fd, 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, ne_get_status, 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.

If a request is being using a non-idempotent method such as POST, the NE_REQFLAG_IDEMPOTENT flag should be disabled; see ne_set_request_flag.  

RETURN VALUE

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.  

ERRORS

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.

EXAMPLE

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);
