3、两次请求的日志信息，发现当 $_SERVER[‘HTTP_USER_AGENT’] 的值为 okhttp/3.12.0 时，$_SERVER[‘HTTP_ACCEPT’] 不存在

    'HTTP_ACCEPT' => '*/*'
    'HTTP_USER_AGENT' => 'PostmanRuntime/7.22.0'

    'HTTP_USER_AGENT' => 'okhttp/3.12.0'

4、要求 Android 客户端在 Headers 中明确声明 Accept，当 $_SERVER[‘HTTP_USER_AGENT’] 的值为 okhttp/3.12.0 时，$_SERVER[‘HTTP_ACCEPT’] 的值为 application/json; version=10.4。不再报错。

5、准备在服务端，做一下判断，当不存在 $_SERVER[‘HTTP_ACCEPT’] 时，就不使用 $_SERVER[‘HTTP_ACCEPT’]。编辑 /common/behaviors/RequestLogBehavior.php

            $message = [

                'user_id' => $userId,
                '$_SERVER' => [
                    'HTTP_ACCEPT_LANGUAGE' => $_SERVER['HTTP_ACCEPT_LANGUAGE'] ?? '',
                    'HTTP_ACCEPT' => $_SERVER['HTTP_ACCEPT'] ?? '',
                    'HTTP_HOST' => $_SERVER['HTTP_HOST'],

            ];
