Guzzle 在 16kB 后截断 headers

Question

我在 php7.4.

的 ubuntu 机器上安装了 curl 7.58 和 guzzle 7.3（源代码：7008573）

当我运行一个请求

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => 'http://mockbin.org/bin/e61ded3e-d2e1-4071-8c27-9c35f1d7cb72?foo=bar&foo=baz',
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_HEADER => true,
));

$response = curl_exec($curl);

// Then, after your curl_exec call:
$header_size = curl_getinfo($curl, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

curl_close($curl);
echo $header;

我可以看到整个延续令牌都在那里。而当我运行使用 guzzle 时，你可以看到我得到了什么：

>>> $client = new GuzzleHttp\Client();
=> GuzzleHttp\Client {#4501}
>>> $res = $client->head('http://mockbin.org/bin/e61ded3e-d2e1-4071-8c27-9c35f1d7cb72?foo=bar&foo=baz');
=> GuzzleHttp\Psr7\Response {#4524}

如您所见，延续令牌运行恰好位于 16kb 上。（16384 个字符）。

我在写这里之前检查了很多东西，但是，我似乎无法弄清楚。我看不到会导致此问题的任何 guzzle 配置。是否有任何我应该更改的默认值？

Answer 1

这是 curl 7.58 中的错误。它已在 7.59 版本中修复。 curl 应该支持最大 header 大小 CURL_MAX_HTTP_HEADER (100kB)。参见 this issue and this email chain。

在错误修复之前，curl 会在将超过 CURL_MAX_WRITE_SIZE (16kB) 的 header 传递给 header 回调函数 (doc). Guzzle is affected since it uses CURLOPT_HEADERFUNCTION internally (Guzzle source, PHP docs) 之前意外地将其切碎。

解决方案是升级系统的 curl 安装，这可能并不简单。

Guzzle 在 16kB 后截断 headers

Guzzle truncates headers after 16kB

php

ubuntu

curl
