php - Guzzle后置参数问题

Question

当使用 2 个参数进行 POST 请求时:

return $this->perform($client->post("/authenticate",null, array(
  "username" => 'radupass',
  "password" => '@alcool', //starting with an @
)));

哪里$客户:

/**
* @return \Guzzle\Service\Client
*/
public function getClient()
{
  if ($this->_client === null) {
    $this->_client = new Guzzle\Service\Client($this->baseUrl, $this->_options);
    $this->_client->setDefaultHeaders(array(
      "X-WebsiteId" => $this->websiteId,
      "X-AccessToken" => $this->accessToken,
    ));
}
return $this->_client;
}

我得到以下异常:

2013/05/29 11:08:29 [error] [exception.Guzzle\Common\Exception\InvalidArgumentException] exception 'Guzzle\Common\Exception\InvalidArgumentException' with message 'Unable to open lcool for reading' in /home/xxx/site/vendor/guzzle/guzzle/src/Guzzle/Http/Message/PostFile.php:58

#6 /home/xxx/site/frontend/components/SubServerClient.php(117): Guzzle\Http\Client->post('/authenticate', NULL, Array)

似乎客户端正在尝试打开一个文件。

编辑

查看我在以下位置看到的 Guzzle 源代码:

https://github.com/guzzle/guzzle/blob/master/src/Guzzle/Http/Message/RequestFactory.php#L88

 if (is_array($body) || $body instanceof Collection) {
                // Normalize PHP style cURL uploads with a leading '@' symbol
                foreach ($body as $key => $value) {
                    if (is_string($value) && substr($value, 0, 1) == '@') {
                        $request->addPostFile($key, $value);
                        unset($body[$key]);
                    }
                }
                // Add the fields if they are still present and not all files
                $request->addPostFields($body);
            }

如果我想转义那个角色怎么办？

似乎是 cURL 本身的一个已知问题:

Using CURL in PHP to post text data starting with "@"

一种解决方案是使用百分比编码，“@”符号将是“%40”，尽管这需要一些额外的工作。

另见 this线程。
