使用 PHP 的 freebase cURL 和 mqlwrite

Question

您好，我正在 Freebase 沙箱上进行一些测试，但我无法让以下请求正常工作。它挂起很长时间然后什么也不返回。我还输出了curl_getinfo()，如果它可以帮助任何人找出我出错的地方。

echo $uri = "http://".$this->config['apiSandboxHost'].'/'.$this->config['apiWritePath'].'={"create":"unless_exists","type":"/user/docs/music/note","name":"A","id":null}';

$ch = curl_init($uri);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$headers = array();
$headers[] = 'X-Metaweb-Request : idio';
$headers[] = 'Content-length: 78';
$headers[] = 'Content-type: application/x-www-form-urlencoded';
$headers[] = 'Cookie: '.  implode(';', $this->authCookies);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$output = curl_exec($ch);
pr(curl_getinfo($ch));
curl_close($ch);
echo $output;

输出

http://sandbox.freebase.com/api/service/mqlwrite?query={"create":"unless_exists","type":"/user/docs/music/note","name":"A","id":null}

Array
(
    [url] => http://sandbox.freebase.com/api/service/mqlwrite?query={"create":"unless_exists","type":"/user/docs/music/note","name":"A","id":null}

)

预先感谢您的帮助！

这最终成为我向 freebase 发送数据的方式的问题。一旦我添加

curl_setopt($ch, CURLOPT_POSTFIELDS, $query);

它一切都很好。

这很奇怪，因为只有当我将数据作为 post 变量发送并将内容添加到请求的查询字符串中时，我才能使其正常工作。
