Question

我在以下cURL请求中获得了一个空白的响应主体，但只在一台机器上运行（osx运行两个流浪盒）。我检查并重新检查项目代码是否存在，它确实适用于我使用的所有其他机器..除了ONE。有什么想法吗？

我在PHP中的调用是POSTRequestTrusted(/api/login, <some_json_data>

public static function POSTRequestTrusted($service_name, $data) {

  self::checkApiKey(); //checks the key is set

  return self::execCURLRequest("POST", $service_name, array('Content-Type: application/json',
          'Accept: application/json',
          'Authorization: Basic ' . self::$apiKey )
      , $data);
}

public static function execCURLRequest($type, $service_name = null, $custom_headers = null, $data = null) {

  //If the verb is unexpected, throw exception
  if($type !== "GET"
      and $type!== "POST"
      and $type!== "DELETE"
      and $type!== "PUT"
      and $type!== "PATCH" ) 
    { return -1 ;}

  //If calling a service, or just pinging the base hostname:port
  if($service_name !== null) {
    $full_url = self::$apiBase . $service_name;
  } else {
    $full_url = self::$apiBase;
  }

  // initialize cURL
  $ch = curl_init($full_url);

  // SET the HTTP VERB type, unless it's a POST which doesn't require anything
  if($type == 'PUT' or $type == 'DELETE' or $type == 'PATCH'){
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $type);
  } else if ($type == 'GET'){
    curl_setopt($ch, CURLOPT_HTTPGET, true);
  }
  //Flag needed to return response
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

  // custom headers are needed for testing trusted client calls.
  if($custom_headers !== null){
    $full_header = $custom_headers;
  } else {
    $full_header = self::$STD_HEADER;
  }

  curl_setopt($ch, CURLOPT_HTTPHEADER, $full_header); //Set the Header
  curl_setopt($ch, CURLOPT_HEADER, 1); // return headers?

  // If data was present, encode it and append to request
  if($data !== null){
    $json_data = json_encode($data);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json_data);
  }

  $response = curl_exec ($ch);

  // parse the entire response, down to the header and body
  list($response_header, $body) = explode("\r\n\r\n", $response, 2);

  $response_body = json_decode($body);

  curl_close ($ch);

  return array($response_header, $response_body);

输出：

HTTP\\/1.1 200 OK\\r\\nDate: Tue, 24 Jun 2014 22:41:46 GMT\\r\\nServer: Apache\\/2.4.9 (Ubuntu)\\r\\nX-Powered-By: PHP\\/5.5.13-2+deb.sury.org~precise+1\\r\\nCache-Control: no-store\\r\\nPragma: no-cache\\r\\nContent-Length: 174\\r\\nContent-Type: application\\/json",null

Answer 1

  $response_body = json_decode($body);

  curl_close ($ch);

  return array($response_header, $response_body);

返回值

以适当的PHP类型返回json中编码的值。值true，false和null分别返回为TRUE，FALSE和NULL。 如果无法解码json或编码数据深于递归限制，则返回NULL。

你应该检查实体返回的是什么，因为它没有正确解码。你回来的内容长度标题说你应该有174个字节的某事。
