invalid header error on sending a request with curl
curl, php
Solution
You are surprisingly getting the error
Bad Request - Invalid Header
HTTP Error 400. The request has an invalid header name.
Because you use an invalid header name :)
You use
Content-Type : application/json; charset=utf-8
Notice the space in the header name
The correct usage would be:
Content-Type: application/json; charset=utf-8
Problem
here is my code ``` echo 22; $url = 'http://www.10bet.com/pagemethods.aspx/GetLeaguesContent'; $fields = array( 'BranchID' => urlencode('1') , 'LeaguesCollection' => urlencode('10098') , ); $fields_string = ''; foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; } rtrim($fields_string, '&'); $ch = curl_init(); curl_setopt($ch,CURLOPT_URL, $url); curl_setopt($ch,CURLOPT_POST, count($fields)); curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string); curl_setopt($ch, CURLINFO_HEADER_OUT, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type : application/json; charset=utf-8')); $result = curl_exec($ch); curl_close($ch); var_dump( $result ); ``` i keep getting ``` Bad Request - Invalid Header HTTP Error 400. The request has an invalid header name. ```
