Detailed Description
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:
- Create an Ecore_Con_Url object with ecore_con_url_new(url);
- 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)
- 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):
Simple usage 2 (HTTP POST):
Simple Usage 3 (FTP download):
Simple Usage 4 (FTP upload as ftp://ftp.example.com/file):
Simple Usage 5 (FTP upload as ftp://ftp.example.com/dir/file):
These are complete examples for the API:
Enumeration Type Documentation
enum _Ecore_Con_Url_Time |
The type of condition to use when making an HTTP request dependent on time, so that headers such as "If-Modified-Since" are used.
Function Documentation
EAPI void ecore_con_url_additional_header_add | ( | Ecore_Con_Url * | url_con, |
const char * | key, | ||
const char * | value | ||
) |
Adds an additional header to the request connection object.
- Parameters
-
url_con Connection object key Header key value Header value
Adds 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.
Some functions like ecore_con_url_time() also add headers to the request.
- Examples:
- ecore_con_url_cookies_example.c, and ecore_con_url_headers_example.c.
EAPI void ecore_con_url_additional_headers_clear | ( | Ecore_Con_Url * | url_con | ) |
Cleans additional headers.
- Parameters
-
url_con Connection object to clean additional headers.
Cleans additional headers associated with a connection object (previously added with ecore_con_url_additional_header_add()).
EAPI void ecore_con_url_cookies_clear | ( | Ecore_Con_Url * | url_con | ) |
Clears currently loaded cookies.
- Parameters
-
url_con Ecore_Con_Url instance which will be acted upon.
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()
.
- Note
- This function will initialize the cookie engine if it has not been initialized yet.
-
The cookie files set by ecore_con_url_cookies_file_add() aren't loaded immediately, just when the request is started. Thus, if you ask to clear the cookies, but has a file already set by that function, the cookies will then be loaded and you will have old cookies set. In order to don't have any old cookie set, you need to don't call ecore_con_url_cookies_file_add() ever on the
url_con
handler, and call this function to clear any cookie set by a previous request on this handler.
- Examples:
- ecore_con_url_cookies_example.c.
EAPI void ecore_con_url_cookies_file_add | ( | Ecore_Con_Url * | url_con, |
const char *const | file_name | ||
) |
Adds a file to the list of files from which to load cookies.
- Parameters
-
url_con Ecore_Con_Url instance which will be acted upon. file_name Name of the file that will be added to the list.
Files must contain cookies defined according to two possible formats:
- HTTP-style header ("Set-Cookie: ...").
- Netscape/Mozilla cookie data format.
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.
- Note
- This function will initialize the cookie engine if it has not been initialized yet.
- Examples:
- ecore_con_url_cookies_example.c.
EAPI void ecore_con_url_cookies_ignore_old_session_set | ( | Ecore_Con_Url * | url_con, |
Eina_Bool | ignore | ||
) |
Controls whether session cookies from previous sessions shall be loaded.
- Parameters
-
url_con Ecore_Con_Url instance which will be acted upon. ignore If EINA_TRUE
, ignore session cookies when loading cookies from files. IfEINA_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.

- ecore_con_url_cookies_file_add()
- Examples:
- ecore_con_url_cookies_example.c.
EAPI void ecore_con_url_cookies_init | ( | Ecore_Con_Url * | url_con | ) |
Enables the cookie engine for subsequent HTTP requests.
- Parameters
-
url_con Ecore_Con_Url instance which will be acted upon.
After this function is called, cookies set by the server in HTTP responses will be parsed and stored, as well as sent back to the server in new HTTP requests.
- Note
- Even though this function is called
ecore_con_url_cookies_init()
, there is no symmetrical shutdown operation.
- Examples:
- ecore_con_url_cookies_example.c.
EAPI Eina_Bool ecore_con_url_cookies_jar_file_set | ( | Ecore_Con_Url * | url_con, |
const char *const | cookiejar_file | ||
) |
Sets the name of the file to which all current cookies will be written when either cookies are flushed or Ecore_Con is shut down.
- Parameters
-
url_con Ecore_Con_Url instance which will be acted upon. cookiejar_file File to which the cookies will be written.
- Returns
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.
- Note
- This function will initialize the cookie engine if it has not been initialized yet.
- Examples:
- ecore_con_url_cookies_example.c.
EAPI void ecore_con_url_cookies_jar_write | ( | Ecore_Con_Url * | url_con | ) |
Writes all current cookies to the cookie jar immediately.
- Parameters
-
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.
- Note
- This function will initialize the cookie engine if it has not been initialized yet.
- Examples:
- ecore_con_url_cookies_example.c.
EAPI void ecore_con_url_cookies_session_clear | ( | Ecore_Con_Url * | url_con | ) |
Clears currently loaded session cookies.
- Parameters
-
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()
.
- Note
- This function will initialize the cookie engine if it has not been initialized yet.
-
The cookie files set by ecore_con_url_cookies_file_add() aren't loaded immediately, just when the request is started. Thus, if you ask to clear the session cookies, but has a file already set by that function, the session cookies will then be loaded and you will have old cookies set. In order to don't have any old session cookie set, you need to don't call ecore_con_url_cookies_file_add() ever on the
url_con
handler, and call this function to clear any session cookie set by a previous request on this handler. An easier way to don't use old session cookies is by using the function ecore_con_url_cookies_ignore_old_session_set().
- Examples:
- ecore_con_url_cookies_example.c.

Retrieves headers from last request sent.
- Parameters
-
url_con Connection object to retrieve response headers from.
Retrieves a list containing the response headers. This function should be used after an ECORE_CON_EVENT_URL_COMPLETE event (headers should normally be ready at that time).
- Returns
- List of response headers. This list must not be modified by the user.
- Examples:
- ecore_con_url_cookies_example.c, and ecore_con_url_headers_example.c.

Shuts down the Ecore_Con_Url library.
- Returns
- Number of calls that still uses Ecore_Con_Url
- Note
- This function doesn't call ecore_con_shutdown(). You still need to call it explicitly after calling this one.
- Examples:
- ecore_con_url_cookies_example.c, ecore_con_url_download_example.c, and ecore_con_url_headers_example.c.

EAPI int ecore_con_url_ssl_ca_set | ( | Ecore_Con_Url * | url_con, |
const char * | ca_path | ||
) |
Set a custom CA to trust for SSL/TLS connections.
Specify the path of a file (in PEM format) containing one or more CA certificate(s) to use for the validation of the server certificate.
This function can also disable CA validation if ca_path
is NULL
. However, the server certificate still needs to be valid for the connection to succeed (i.e., the certificate must concern the server the connection is made to).
- Parameters
-
url_con Connection object that will use the custom CA. ca_path Path to a CA certificate(s) file or NULL
to disable CA validation.
- Returns
0
on success. When cURL is used, non-zero return values are equal to cURL error codes.
