在PHP中使用urlfetch替换CURL [英] Replacing CURL with urlfetch in PHP

问题描述

我正在为Google App引擎创建一个应用程序，其中不允许使用CURL。
据我所知，urlFetch是最好的选择。

I'm creating an application for Google App engine, where CURL isn't allowed. As far as I know, urlFetch is the best alternative.

我不知道如果我可以实现与urlFetch相同的结果，但我真的，非常感谢，如果有更多的经验的任何人可以帮助我。

I don't know if I can achieve the same result with urlFetch, but I would really, really appreciate it if anyone with more experience could help me out.

计划是将以下CURL请求转换为urlFetch。如果任何人可以指向正确的方向，或提出一个更好的替代品，我会非常感谢。

The plan was to convert the following CURL requests to urlFetch. If anyone can point me in the right direction, or propose a better alternative, I'd greatly appreciate it.

public function postCall($endpoint, $post_data, $param1, $param2, $json=1, $headers=false) {
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $this->options['url'].$endpoint);
curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);

if ($headers && is_array($headers)) {
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
}

$post_data['req_token'] = $this->hash($param1, $param2);
curl_setopt($ch, CURLOPT_POST, count($post_data));
if (!$headers) 
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post_data));
else
    curl_setopt($ch,CURLOPT_POSTFIELDS, $post_data);
$this->debug('POST params: ' . json_encode($post_data));
$result = curl_exec($ch);
if ($result === false) {
    $this->debug('CURL error: '.curl_error($ch));
    return false;
}
$this->debug('HTTP response code' . curl_getinfo($ch, CURLINFO_HTTP_CODE));
$this->debug('POST return ' . $result);

// close connection
curl_close($ch);

if ($json)
    return json_decode(utf8_encode($result), true);
else
    return $result;}

推荐答案

您查看了 Urlfetch文档和关于封装的PHP文章？您可以尝试使用此 live shell 。

Did you look at the Urlfetch documentation and the linked PHP article about wrappers?. You can experiment with this live shell.

代码可以是翻译成诸如：

The code could be translated to something like:

public function postCall($endpoint, $post_data, $param1, $param2, $json=1, $headers=false) {
  $post_data['req_token'] = $this->hash($param1, $param2);
  $this->debug('POST params: ' . json_encode($post_data));
  $data = http_build_query($post_data);
  $options =
      array("http"=>
        array(
          "method" => "POST",
          "content" => $post_data,
        )
      );
  if ($headers && is_array($headers)) {
      $options["http"]["header"] = $headers;
  }
  $context = stream_context_create($options);
  $result = file_get_contents("http://app.com/path?query=update", false, $context);

  if ($result === FALSE) {
      $this->debug('Error: '. print_r($http_response_header));
      return FALSE;
  }
  $this->debug('Response headers:' . print_r($http_response_header)); // To get the status code you would need to parse that response
  $this->debug('POST return ' . $result);

  if ($json)
      return json_decode(utf8_encode($result), true);
  else
      return $result;
}
