/src/Request.php的633行，应为-3，项目中写成了3，部分代码：

    public function recv()
    {
        retry_recv:
        if (self::STATUS_WAITING !== $this->_status) {
            throw new \BadMethodCallException('You can\'t recv because client is not in waiting stat.');
        }
        $this->client->recv($this->getTimeout());
        $this->_status = self::STATUS_NONE;
        $this->_time = microtime(true) - $this->_start_time;

        $is_report = $this->getExceptionReport() & HttpExceptionMask::E_CONNECT;
        $statusCode = $this->client->statusCode;
        $errCode = $this->client->errCode;
        if ($statusCode < 0 || $errCode !== 0) {
            if ($is_report) {
                if ($statusCode === -1) {
                    $message = 'Connect timeout! the server is not listening on the port or the network is missing!';
                } elseif ($statusCode === -2) {
                    $timeout = $this->getTimeout();
                    $message = "Request timeout! the server hasn't responded over the timeout setting({$timeout}s)!";
                } elseif ($statusCode === 3) { //这里写错啦！
                    $message = 'Connection is forcibly cut off by the remote server';
                } else {
                    $message = "Linux Code {$errCode}: " . swoole_strerror($errCode);
                }
                $exception = new ConnectException($this, $statusCode, $message);
                $ret = $this->callInterceptor('exception', $exception);
                if (!$ret) {
                    $this->tryToRevertClientToPool(true);
                    throw $exception;
                }
            } else {
                // Exception is no longer triggered after an exception is ignored
                $this->setExceptionReport(HttpExceptionMask::E_NONE);
            }
        }
