/*
|
|
* Brief usage:
|
|
* 1. Create an Ecore_Con_Url object
|
|
* 2. Register to receive the ECORE_CON_EVENT_URL_COMPLETE event
|
|
* (and optionally the ECORE_CON_EVENT_URL_DATA event to receive
|
|
* the response, e.g. for HTTP/FTP downloads)
|
|
* 3. Set the URL with ecore_con_url_url_set(...);
|
|
* 4. Perform the operation with ecore_con_url_get(...);
|
|
*
|
|
* Note that it is good to reuse Ecore_Con_Url objects wherever possible, but
|
|
* bear in mind that each one can only perform one operation at a time.
|
|
* You need to wait for the ECORE_CON_EVENT_URL_COMPLETE event before re-using
|
|
* or destroying the object.
|
|
*
|
|
* Example Usage 1 (HTTP GET):
|
|
* ecore_con_url_url_set(url_con, "http://www.google.com");
|
|
* ecore_con_url_get(url_con);
|
|
*
|
|
* Example usage 2 (HTTP POST):
|
|
* ecore_con_url_url_set(url_con, "http://www.example.com/post_handler.cgi");
|
|
* ecore_con_url_post(url_con, data, data_length, "multipart/form-data");
|
|
*
|
|
* Example Usage 3 (FTP download):
|
|
* ecore_con_url_url_set(url_con, "ftp://ftp.example.com/pub/myfile");
|
|
* ecore_con_url_get(url_con);
|
|
*
|
|
* Example Usage 4 (FTP upload as ftp://ftp.example.com/file):
|
|
* ecore_con_url_url_set(url_con, "ftp://ftp.example.com");
|
|
* ecore_con_url_ftp_upload(url_con, "/tmp/file", "user", "pass", NULL);
|
|
*
|
|
* Example Usage 5 (FTP upload as ftp://ftp.example.com/dir/file):
|
|
* ecore_con_url_url_set(url_con, "ftp://ftp.example.com");
|
|
* ecore_con_url_ftp_upload(url_con, "/tmp/file", "user", "pass","dir");
|
|
*
|
|
* FIXME: Support more CURL features: Progress callbacks and more...
