Tizen Native API
4.0
|
Utility functions that set up, use and shut down the Ecore URL Connection library.
These functions are a shortcut to make it easy to perform http requests (POST, GET, etc).
Brief usage: 1. Create an Ecore_Con_Url object with ecore_con_url_new(url); 2. Register to receive the ECORE_CON_EVENT_URL_COMPLETE event (and optionally the ECORE_CON_EVENT_URL_DATA and ECORE_CON_EVENT_URL_PROGRESS event to receive the response, e.g. for HTTP/FTP downloads) 3. 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.
If it's necessary to change the Ecore_Con_Url object url, use ecore_con_url_url_set().
Simple Usage 1 (HTTP GET):
ecore_con_url_url_set(url_con, "http://www.google.com"); ecore_con_url_get(url_con);
Simple 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");
Simple Usage 3 (FTP download):
fd = creat(filename, 0644) ecore_con_url_url_set(url_con, "ftp://ftp.example.com/pub/myfile"); ecore_con_url_fd_set(url_con, fd); ecore_con_url_get(url_con);
Simple 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);
Simple 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");

const char * | value | ||
) |
Adds an additional header to the request connection object.
url_con | Connection object |
key | Header key |
value | Header value |
Add an additional header (User-Agent, Content-Type, etc.) to the request connection object. This addition will be valid for only one ecore_con_url_get() or ecore_con_url_post() call.

handler, and call this function to clear any cookie set by a previous request on this handler.void ecore_con_url_cookies_file_add | ( | Ecore_Con_Url * | url_con, |

Files must contain cookies defined according to two possible formats:
Cookies will only be read from this file. If you want to save cookies to a file, use ecore_con_url_cookies_jar_file_set(). Also notice that this function supports the both types of cookie file cited above, while ecore_con_url_cookies_jar_file_set() will save only in the Netscape/Mozilla's format.
Please notice that the file will not be read immediately, but rather added to a list of files that will be loaded and parsed at a later time.
void ecore_con_url_cookies_ignore_old_session_set | ( | Ecore_Con_Url * | url_con, |

ignore | If EINA_TRUE , ignore session cookies when loading cookies from files. If EINA_FALSE , all cookies will be loaded. |
Session cookies are cookies with no expire date set, which usually means they are removed after the current session is closed.
By default, when Ecore_Con_Url loads cookies from a file, all cookies are loaded, including session cookies, which, most of the time, were supposed to be loaded and valid only for that session.
If ignore
is set to EINA_TRUE
, when Ecore_Con_Url loads cookies from the files passed to ecore_con_url_cookies_file_add()
, session cookies will not be loaded.

EINA_TRUE
is the file name has been set successfully, EINA_FALSE
otherwise.Cookies are written following Netscape/Mozilla's data format, also known as cookie-jar.
Cookies will only be saved to this file. If you need to read cookies from a file, use ecore_con_url_cookies_file_add() instead.
void ecore_con_url_cookies_jar_write | ( | Ecore_Con_Url * | url_con | ) |
Writes all current cookies to the cookie jar immediately.
url_con | Ecore_Con_Url instance which will be acted upon. |
A cookie-jar file must have been previously set by ecore_con_url_jar_file_set
, otherwise nothing will be done.
void ecore_con_url_cookies_session_clear | ( | Ecore_Con_Url * | url_con | ) |
Clears currently loaded session cookies.
url_con | Ecore_Con_Url instance which will be acted upon. |
Session cookies are cookies with no expire date set, which usually means they are removed after the current session is closed.
The cleared cookies are removed and will not be sent in subsequent HTTP requests, nor will they be written to the cookiejar file set via ecore_con_url_cookies_jar_file_set()
.
