如何解决Zoho项目API一般错误6500?

我正在开发Zoho项目API。我在发送HTTP post时获得了API密钥。发送post请求时,我收到一个错误。

API调用代码

$request_url ='https://projectsapi.zoho.com/restapi/portal/[PORTALID]/projects/'.$proj_id.'/bugs/?';

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

$request_parameters = array(
'authtoken' => 'token',
'title' =>'Meter No '.$msn.'_'.$issue_name,
'assignee'=>$assigne_name,
'flag'=>'Internal',
'classification_id'=> $class_id,
'module_id'=>$module_id,
'severity_id'=>$sevr_id,
'CHAR2'=>$ref_no,
'LONG1'=>$msn,

 );

 curl_setopt($ch, CURLOPT_POST, TRUE);
 curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($request_parameters));

 /* Here you can set the Response Content Type */
 curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json'));
 /* Let's give the Request Url to Curl */
 curl_setopt($ch, CURLOPT_URL, $request_url);
 /*
 Yes we want to get the Response Header
 (it will be mixed with the response body but we'll separate that after)
 */
 curl_setopt($ch, CURLOPT_HEADER, TRUE);
 /* Allows Curl to connect to an API server through HTTPS */
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
/* Let's get the Response ! */
$response = curl_exec($ch);
/* We need to get Curl infos for the http_code */
$response_info = curl_getinfo($ch);
/* Don't forget to close Curl */
curl_close($ch);
/* Here we get the Response Body */
$response_body = substr($response, $response_info['header_size']);
// Response HTTP Status Code
echo "Response HTTP Status Code : ";
echo $response_info['http_code'];
echo "\n";
// Response Body
echo "Response Body : ";
echo $response_body;

我得到的回应是

Response HTTP Status Code : 400
Response Body : {"error":{"code":6500,"message":"General Error"}}

提出了一种解决方案 here . 但这对我没有任何帮助。

Zoho自身正在提供 PHP Example 我正在使用的。

好的,我补充道 $request_url .= '?' . http_build_query($request_parameters); 之后 curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($request_parameters)); 然后再次检查响应。URL位于下面

https://projectsapi.zoho.com/restapi/portal/[PORTALID]/projects/[PROJECTID]/bugs/?authtoken=key&title=Meter+No+002999000368_Site+Comm+Issue&assignee=Laar+Circle&flag=Internal&classification_id=1139168000000297069&module_id=1139168000000019372&severity_id=1139168000000007003&CHAR1=farhan_javaid&CHAR2=20372210038297U&LONG1=002999000368

有 + 在导致问题的空间之间登录。单词之间应该有空格。喜欢 Meter+No+002999000368_Site+Comm+Issue 应该是 Meter No 002999000368_Site Comm Issue .

如何消除此错误。任何帮助都将不胜感激。
