使用CURL PHP发布请求返回错误400？ 静态错误的请求

Question

I am doing a post request using cUrl and PHP, the code is mentioned below

<?php            
 $data = array("employeeAuth" => array("employeeNumber" => "376819"));
 $data_post = json_encode($data);
 echo $data_post;
 $cSession = curl_init('http://10.40.4.170:80/xxxxxx/eeee/zzzz/kkkk');
 curl_setopt($cSession,CURLOPT_CUSTOMREQUEST,"POST");
 curl_setopt($cSession,CURLOPT_POSTFIELDS,$data_post);
 curl_setopt($cSession,CURLOPT_RETURNTRANSFER,true);
 curl_setopt($cSession,CURLOPT_HTTPHEADER,array(
            "Content-Type:application/json;charset=UTF-8",
            "Content-Length:". strlen($data_string)
           ));
 $result=curl_exec($cSession);
 curl_close($cSession);
 echo $result;
?>

After this code runs I get Error 400 from the server as response stating that the request is Syntactically wrong. Please let me know If I am doing anything wrong.

You are setting Content-Length based on $data_string , but I think you meant $data_post since $data_string isn't defined anywhere. But, try removing the Content-Length entry all together, CURL will calculate and include it for you. Also, include a space after the colon in each header.
