http-client 加代理 偶尔报错Content-Length: 0

问题描述

加了proxy后，偶尔成功，偶尔失败，失败了就会报错这个；
之前使用的是workerman:beta版本， 最近升级到rc就报错了。
感觉是TcpConnection或者AsyncTcpConnection的问题。

求大佬@walkor，指点迷津

程序代码

demo.php

use Workerman\Worker;

require __DIR__.'/vendor/autoload.php';

/**
 * Workerman: v5.0.0-rc.2
 * http-client: v2.2.8
 * revolt/event-loop:v1.0.6
 * event: revolt
 *
 */

$worker = new Worker();

// $worker->count = 4;

$worker->onWorkerStart = function () {
    $http = new Workerman\Http\Client([
        'max_conn_per_addr' => 128,
        'keepalive_timeout' => 60,
        'connect_timeout' => 5,
        'timeout' => 30,
    ]);

    $option = [
        'method' => 'GET',
        'headers' => [],
        'data' => '',
        'proxy' => 'http://127.0.0.1:1279',
    ];

    $response = $http->request('http://myip.ipip.net/', $option);

    echo (string) $response?->getBody().PHP_EOL;
};
Worker::runAll();

报错信息

操作系统及workerman/webman等框架组件具体版本

系统：MAC/linux
Workerman: v5.0.0-rc.2
http-client: v2.2.8
event: revolt
revolt/event-loop:v1.0.6

调试研究-发现

1.TcpConnection中baseRead方法的 548行：

$buffer = @\fread($socket, self::READ_BUFFER_SIZE);

获取到的buffer偶尔会携带"Content-Length: 0" 开头
