webman升级到1.6，nginx到webman 部分请求 504

问题描述

webman升级到1.6后（workerman 为5.1），通过nginx转发请求到webman，部分请求会出现504(nginx)侧。在应用系统中加debug代码，发现请求已经被执行，在超过nginx的超时时间后，nginx 记录504日志。直觉是在webman发送数据的时候，出现了异常。

程序代码或配置

public function get()
    {
        var_dump(1);
        $user = $this->getUser();
        unset($user['passhash']);
        $workspace = $this->getWorkspaceModule()->getById($user['current_workspace_id']);
        $role = $this->getWorkspaceMemberModule()->getMemberRole($user['id'], $workspace->id);
        if (!$role) {
            throw new AccessDeniedException();
        }
        $taskTypes = $this->getWorkspaceModule()->getWorkspaceTaskTypes($workspace->uuid);
        $workspace->task_types = $taskTypes;
        $user['workspace_role'] = $role;
        $user['workspace'] = $workspace;
        $user['workspaces'] = $this->getWorkspaceModule()->getUserWorkspaces($user['id'], ['id', 'uuid', 'name']);

        foreach ($user['workspaces'] as $key => $w) {
            if ($workspace->id == $w->id) {
                unset($user['workspaces'][$key]);
                break;
            }
        }
        $user['workspaces'] = array_values($user['workspaces']->toArray());
        var_dump(2);
        return $this->json($user);
    }

请求发起后，能够在stdout中立即看到 var_dump 打出的1和2,表明业务代码已经执行。
但是在nginx中，超过超时时间后，记录504日志。
