Helper function that creates outbound HTTP connection.
|
||
|
|
|
||
|
|
`url` is a URL to fetch. It must be properly URL-encoded, e.g. have
|
||
|
|
no spaces, etc. By default, `mg_connect_http()` sends Connection and
|
||
|
|
Host headers. `extra_headers` is an extra HTTP headers to send, e.g.
|
||
|
|
`"User-Agent: my-app\r\n"`.
|
||
|
|
If `post_data` is NULL, then GET request is created. Otherwise, POST request
|
||
|
|
is created with the specified POST data. Note that if the data being posted
|
||
|
|
is a form submission, the `Content-Type` header should be set accordingly
|
||
|
|
(see example below).
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
|
||
|
|
```c
|
||
|
|
nc1 = mg_connect_http(mgr, ev_handler_1, "http://www.google.com", NULL,
|
||
|
|
NULL);
|
||
|
|
nc2 = mg_connect_http(mgr, ev_handler_1, "https://github.com", NULL, NULL);
|
||
|
|
nc3 = mg_connect_http(
|
||
|
|
mgr, ev_handler_1, "my_server:8000/form_submit/",
|
||
|
|
"Content-Type: application/x-www-form-urlencoded\r\n",
|
||
|
|
"var_1=value_1&var_2=value_2");
|
||
|
|
```
