php - 内容类型不随 CURLOPT_HTTPHEADERS 改变

Question

我正在尝试使用以下代码将一些 JSON 发布到带有 cURL 的 Web 服务:

$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_URL, 'http://index.yolink.com/index/define?o=json&ak=APIKEY');
curl_setopt($ch, CURLOPT_HTTPHEADERS,array('Content-Type: application/json'));

$data = array(
  'ignore-robots' => 'false',
      'language' => 'english',
  'crawl-delay' => '0',
  'depth' => '3',
  'root' => array('url' => 'http://bartleby.com/')
);

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
$result=curl_exec($ch);
var_dump($result);

我得到以下返回:

string(282) "HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Access-Control-Allow-Origin: * Content-Type: text/plain Content-Length: 120 Date: Fri, 18 Mar 2011 19:03:23 GMT {"code":"error.indexdefinition.invalid","message":"Invalid content provided for /define. Error:Premature end of file.."}"

我找到了this blog post这似乎是相关的——它似乎确实正在发送 text/plain即使我已经指定了 ContentType在CURLOPT_HTTPHEADERS如application/json 。但添加 http_build_query没有帮助。

预先感谢您的帮助!

我相信它应该是HTTPHEADER，而不是HTTPHEADERS。
