您不应将所有参数映射到URL，

You should not be mapping all the parameters to URL,

/**
 * Manually routed method. we can specify as many routes as we want
 *
 * @url POST addcomment/{token}/{email}/{comment}/{story_id}
 */
function addComment($token,$email,$comment,$story_id){
    return $this->dp->insertComment($token,$email,$comment,$story_id);
}

这样做，API只能接受URL，例如

By doing so the API can only accept URL such as

http://localhost/Restler/public/examples/news/addcomment/900150983cd24fb0d6963f7d28e17f72/kamal@gmail.com/commentusingcurl/2

将您的API方法更改为

Change you API method to

/**
 * Manually routed method. we can specify as many routes as we want
 *
 * @url POST addcomment
 */
function addComment($token,$email,$comment,$story_id){
    return $this->dp->insertComment($token,$email,$comment,$story_id);
}

然后您的cURL示例应该可以正常工作

Then your cURL example should work fine

$data_string = "token=900150983cd24fb0d6963f7d28e17f72&email=kamal@gmail.com&comment=commentusingcurl&story_id=2";

$ch = curl_init('http://localhost/Restler/public/examples/news/addcomment');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
//curl_setopt($ch, CURLOPT_HTTPHEADER,array("Content-Type : text","Content-lenght:".strlen($data_string)));                                                                                                                                     
$result = curl_exec($ch);
