php-curl小记

用jQuery：

 $.ajax({
   url:url,
   type:"POST",
   data:data,
   contentType:"application/json; charset=utf-8",
   dataType:"json",
   success: function(){
     ...
   }
 })

php curl (自定义post请求  设置header头信息)

 $data = array("name" => "Hagrid", "age"=> "36");
 $data_string = json_encode($data);
 $ch = curl_init('http://api.local/rest/users');
 curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
 curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($ch, CURLOPT_HTTPHEADER, array(
     'Content-Type: application/json',
     'Content-Length: ' . strlen($data_string))
 );
 $result = curl_exec($ch);
