我正试图使用phpccurl从surveymonkey的api中检索一些数据,但我一直收到500个错误。
这是我的代码:

  $requestHeaders = array(
    'Content-Type: application/json',
    'Authorization: Bearer ' . $accessToken,
  );

  $baseUrl = 'https://api.surveymonkey.net';
  $endpoint = '/v2/surveys/get_survey_list?api_key=XXXXXXXXXXXXXX';

  $fields = array(
    'fields' => array(
      'title','analysis_url','date_created','date_modified'
    )
  );

  $fieldsString = json_encode($fields);

  $ch  = curl_init();
  curl_setopt($ch, CURLOPT_URL, $baseUrl . $endpoint);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, $requestHeaders);
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $fieldsString);

  $result = curl_exec($ch);

  curl_close($ch);

我得到的答复是
{
    "status": 500,
    "request_id": "e0c10adf-ae8f-467d-83af-151e8e229618",
    "error": {
        "message": "Server busy, please try again later."
    }
}

这在命令行上非常有效:
curl -H 'Authorization:bearer XXXXX'
     -H 'Content-Type: application/json' https://api.surveymonkey.net/v2/surveys/get_survey_list/?api_key=XXXXXXXX
--data-binary '{"fields":["title","analysis_url","date_created","date_modified"]}'

谢谢!

最佳答案

你很接近,但有几个小错误。
首先,虽然您确实正确地指定了Content-Typeapplication/json),但您没有指定Content-Length
将此更改设置为$requestHeaders,并将其移动到创建$fieldsString的下面:

$requestHeaders = array(
     'Content-Type: application/json',
     'Authorization: Bearer ' . $_GET['code'],
     'Content-Length: ' . strlen($fieldsString)
);

其次,您已将CURLOPT_POST设置为true。这将迫使curl将您的请求视为内容类型为application/x-www-form-urlencoded的表单帖子。这将产生一个问题,因为SurveyMonkey需要内容类型application/json
删除此:
curl_setopt($ch, CURLOPT_POST, true);

换成这个:
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
