耗油后参数问题 - Guzzle post parameter issue

Guzzle post parameter issue

本文关键字：问题参数 | 更新日期: 2023-09-27

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 @
)));

,美元端:

/**
* @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)

客户端似乎正在尝试打开一个文件。

编辑

查看Guzzle源代码，我看到在:

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);
            }

如果我想转义该字符怎么办?

似乎是cURL本身的一个已知问题:

在PHP中使用CURL发布以"@"

开头的文本数据

一个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。

当您查看Guzzle Request Documentation时，您可以发现所有以@符号开头的POST参数都被视为文件路径。参见他们文档中的示例:

$request = $guzzleClient->post($url, $headers, [
    'file_field'   => '@/path/to/file.xml'
]);

我通过setPostField()方法分配POST参数来解决这个问题，下面是我的例子:

$request = $guzzleClient->post($url, $headers);
foreach ($postData as $key => $value) {
    $request = $request->setPostField($key, $value);
}
$guzzleClient->send($request);
