This is a simple example that shows how to make a custom request using Ecore\+\_\+\+Con\+\_\+\+Url.

The full source code for this example can be found at \hyperlink{ecore_con_url_headers_example_8c-example}{ecore\+\_\+con\+\_\+url\+\_\+headers\+\_\+example.\+c}.

The first part of the example is setting the callbacks to be called when an \hyperlink{group__Ecore__Con__Events__Group_ga6ebe51236dac1bc1255b5b390cc9e6e3}{E\+C\+O\+R\+E\+\_\+\+C\+O\+N\+\_\+\+E\+V\+E\+N\+T\+\_\+\+U\+R\+L\+\_\+\+D\+A\+T\+A} or \hyperlink{group__Ecore__Con__Events__Group_gae90b9b857e1e0adc0c7f24e7ccecb44b}{E\+C\+O\+R\+E\+\_\+\+C\+O\+N\+\_\+\+E\+V\+E\+N\+T\+\_\+\+U\+R\+L\+\_\+\+C\+O\+M\+P\+L\+E\+T\+E} event is received. These are the callbacks that are going to be used with this\+:

The {\ttfamily main} code is as simple as the Ecore\+\_\+\+Con\+\_\+\+Url example. It contains some checks for the arguments to see if a G\+E\+T or P\+O\+S\+T request is required\+:


\begin{DoxyCodeInclude}

\textcolor{keywordtype}{int}
main(\textcolor{keywordtype}{int} argc, \textcolor{keyword}{const} \textcolor{keywordtype}{char} *argv[])
\{
   Ecore\_Con\_Url *ec\_url = NULL;
   \textcolor{keyword}{const} \textcolor{keywordtype}{char} *type;
   \hyperlink{group__Eina__Types__Group_ga3fe0caf72e93b1bab1ca8ee3ccf3f226}{Eina\_Bool} r;

   \textcolor{keywordflow}{if} (argc < 3)
     \{
        printf(\textcolor{stringliteral}{"need at least two parameters: < POST|GET >  <url1>\(\backslash\)n"});
        \textcolor{keywordflow}{return} -1;
     \}

\end{DoxyCodeInclude}


Then we start our required libraries and configure a global option to use pipelined requests\+:


\begin{DoxyCodeInclude}

   type = argv[1];

   \textcolor{keywordflow}{if} (strcmp(type, \textcolor{stringliteral}{"POST"}) && (strcmp(type, \textcolor{stringliteral}{"GET"})))
     \{
        printf(\textcolor{stringliteral}{"only POST or GET are supported by this example.\(\backslash\)n"});
        \textcolor{keywordflow}{return} -1;
     \}

   \hyperlink{group__Ecore__Init__Group_ga77757609684a2c922dc5ec398274751b}{ecore\_init}();
   \hyperlink{group__Ecore__Con__Events__Group_gacf5ecf42c516bb9c8b6759721e9559bd}{ecore\_con\_init}();
   \hyperlink{group__Ecore__Con__Url__Group_gac3fbeaf9cde529362e4567fc37e45c9f}{ecore\_con\_url\_init}();

   \textcolor{comment}{// check if requests are being pipelined, and set them if not:}
   \textcolor{keywordflow}{if} (!\hyperlink{group__Ecore__Con__Url__Group_ga1abb9bf94b5d36f19b0809bb8639e17b}{ecore\_con\_url\_pipeline\_get}())
     \hyperlink{group__Ecore__Con__Url__Group_ga39a8588deb7f759d7808496c477fe28e}{ecore\_con\_url\_pipeline\_set}(\hyperlink{group__Eina__Types__Group_ga05c12dacc8b4058994df842b41be85fc}{EINA\_TRUE});

\end{DoxyCodeInclude}


Now we create our request object, but using \hyperlink{group__Ecore__Con__Url__Group_ga2baf5b650b0926f6abd9bd50871ec8eb}{ecore\+\_\+con\+\_\+url\+\_\+custom\+\_\+new()} to use a P\+O\+S\+T or G\+E\+T method depending on the command line arguments. And we also add the event handlers for our callbacks\+:


\begin{DoxyCodeInclude}

   ec\_url = \hyperlink{group__Ecore__Con__Url__Group_ga2baf5b650b0926f6abd9bd50871ec8eb}{ecore\_con\_url\_custom\_new}(argv[2], type);
   \textcolor{keywordflow}{if} (!ec\_url)
     \{
        printf(\textcolor{stringliteral}{"error when creating ecore con url object.\(\backslash\)n"});
        \textcolor{keywordflow}{goto} end;
     \}

   \hyperlink{group__Ecore__Event__Group_gae75b0b1b2c50e73b8e42afc628b00a62}{ecore\_event\_handler\_add}(\hyperlink{group__Ecore__Con__Events__Group_ga6ebe51236dac1bc1255b5b390cc9e6e3}{ECORE\_CON\_EVENT\_URL\_DATA}, 
      \_url\_data\_cb, NULL);
   \hyperlink{group__Ecore__Event__Group_gae75b0b1b2c50e73b8e42afc628b00a62}{ecore\_event\_handler\_add}(\hyperlink{group__Ecore__Con__Events__Group_gae90b9b857e1e0adc0c7f24e7ccecb44b}{ECORE\_CON\_EVENT\_URL\_COMPLETE},
       \_url\_complete\_cb, NULL);

\end{DoxyCodeInclude}


In order to demonstrate our A\+P\+I, some options are set to this request before actually performing it\+:


\begin{DoxyCodeInclude}

   \hyperlink{group__Ecore__Con__Url__Group_ga1f9939c84aa5128d5197f1939d8cffeb}{ecore\_con\_url\_additional\_header\_add}(ec\_url, \textcolor{stringliteral}{"User-Agent"}, \textcolor{stringliteral}{"blablabla"}
      );
   \hyperlink{group__Ecore__Con__Url__Group_ga45a962a3b08b35fb5c1468ebe643ea2b}{ecore\_con\_url\_verbose\_set}(ec\_url, \hyperlink{group__Eina__Types__Group_ga05c12dacc8b4058994df842b41be85fc}{EINA\_TRUE});

   \hyperlink{group__Ecore__Con__Url__Group_ga9834a4bf039957602a8966ae4d628ffb}{ecore\_con\_url\_httpauth\_set}(ec\_url, \textcolor{stringliteral}{"user"}, \textcolor{stringliteral}{"password"}, 
      \hyperlink{group__Eina__Types__Group_ga1feb115f8e9913e806e090d9bd5a7301}{EINA\_FALSE});

   \hyperlink{group__Ecore__Con__Url__Group_gac93f0e4c37e17b87e95212887a097f26}{ecore\_con\_url\_time}(ec\_url, \hyperlink{group__Ecore__Con__Url__Group_gga7fd1cb32a295b11143fb1660dc8bcd6bad3aba66e3ab06bb1c66942641a0b2d29}{ECORE\_CON\_URL\_TIME\_IFMODSINCE},
       0);

\end{DoxyCodeInclude}


Depending on what kind of request was asked (G\+E\+T or P\+O\+S\+T), we use one of the specific functions to perform it\+:


\begin{DoxyCodeInclude}

   \textcolor{keywordflow}{if} (!strcmp(type, \textcolor{stringliteral}{"GET"}))
     r = \hyperlink{group__Ecore__Con__Url__Group_ga46f75358256eec26bd99eef96b25ffa8}{ecore\_con\_url\_get}(ec\_url);
   \textcolor{keywordflow}{else}
     r = \hyperlink{group__Ecore__Con__Url__Group_gaa9da5f3b9c091cf1a755136c5797d39c}{ecore\_con\_url\_post}(ec\_url, NULL, 0, NULL);

\end{DoxyCodeInclude}


After that, we just check for errors, start the main loop, free resources and finally exit\+:


\begin{DoxyCodeInclude}

   \textcolor{keywordflow}{if} (!r)
     \{
        printf(\textcolor{stringliteral}{"could not realize request.\(\backslash\)n"});
        \textcolor{keywordflow}{goto} free\_ec\_url;
     \}

   \hyperlink{group__Ecore__Main__Loop__Group_gaf103b9f668bb3e4fed12e52c6180132d}{ecore\_main\_loop\_begin}();

free\_ec\_url:
   \hyperlink{group__Ecore__Con__Url__Group_ga711510886aaece16f5dee6903c603fb2}{ecore\_con\_url\_free}(ec\_url);
end:
   \hyperlink{group__Ecore__Con__Url__Group_ga0da252aa2c919722894dd41cc6549435}{ecore\_con\_url\_shutdown}();
   \hyperlink{group__Ecore__Con__Events__Group_gaccfd8dd2a1187b71339b5cc39dc83938}{ecore\_con\_shutdown}();
   \hyperlink{group__Ecore__Init__Group_ga768298b932f18d7e7593a447493e5cde}{ecore\_shutdown}();

   \textcolor{keywordflow}{return} 0;
\}

\end{DoxyCodeInclude}
