Question

我正在使用Guzzle登录页面，然后解析DOM以获取下载链接。但是，登录后我不会收到完整的DOM。带有下载链接的HTML即将以DOM字符串开头，然后被截断。

有人知道这可能是什么原因吗？

该页面位于登录名后面，不能公开访问。

注意：我无法共享URL或登录数据，因此很可能无法复制该问题。

这是DOM的结尾

</SCRIPT>
  <TABLE   ALIGN=LEFT CELLSPACING=0 CELLPADDING=1 style='WIDTH:99%;max-width:1000px;'>

（此后什么也没有，但是应该以某种方式不在响应中显示）

PHP：7.1.26

枪口：6.3.3

一些有用的代码：

$response = self::$client->get(self::getConfig()['baseurl'] . '/' . parse_url($mainScreenUri)['path'], [
                'query'   => $query_params,
                'sink'    => date('Y.m.d_H-i-s') . '_sink_.txt',
                'debug'   => TRUE,
                'headers' => [
                    'User-Agent' => 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36',
                    'Accept'     => 'text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3',
                    'Host'       => 'snip',
                ]
            ]
        );

        $x = $response->getBody()->__toString();
        file_put_contents(date('Y.m.d_H-i-s') . '.txt', $x);

由此创建的两个文件都将被剪切，并且不会显示整个正文。

响应调试：

编辑使用流一次只获取几个字节的问题，我也遇到同样的问题。

/** @var \GuzzleHttp\Promise\Promise $promise */
        $promise = self::$client->getAsync(self::getConfig()['baseurl'] . '/' . parse_url($mainScreenUri)['path'], [
                'query'           => $query_params,

                    'Host'       => 'snip',
                    //                    'Referer'    => 'snip/popup.php?user=' . self::getConfig()['username'] . '&pwi=' . $pwi . '&pwh=' . $hpw,
                ],
                'allow_redirects' => [
                    'max' => 50,
                ]
            ]
        );

        /** @var \GuzzleHttp\Psr7\Response $response */
        $response = $promise->wait();

        /** @var \GuzzleHttp\Psr7\Stream $body */
        $body = $response->getBody();

        $dataRead = "";
        while (!$body->eof()) {
            $data     = $body->read(1024);
            $dataRead .= $data;
        }

$dataRead像其他所有东西一样被切断。

我发现了问题。这是一个已损坏的参数，服务器决定返回损坏的HTML，而不是错误消息或什么也没有。
