Description

一种远程调试方法、机顶盒和服务器 技术领域
本公开涉及远程调试技术领域，例如涉及一种远程调试方法、机顶盒和服务器。
背景技术
数字机顶盒、金融智能终端机等终端设备，已经广泛地应用于人们的日常工作生活中。
当用户使用这类终端设备出现故障问题时，该终端设备的运营商通常选择通过电话与用户进行故障沟通，通过电话指导用户，让用户尝试用各种其指导的方法进行故障调试，但是，由于用户的受教育程度各有不同，而且耐性有限，所以通过这种方式解决故障问题费时费力；或者选择派遣维护人员提供上门故障调试服务，但是这样的上门服务，人力和时间成本很高；又或者选择让用户直接将故障终端设备寄到指定维修中心进行维修调试，而这样运输成本也很高，而且时间上也有延误，严重影响用户体验。
现有的针对基于安卓操作系统的智能设备的远程调试工具为调试桥(android debug bridge，adb)，但是abd并不是真正意义上的远程调试工具，因为abd只能局限于内网的内部调试。例如，当用户家中的机顶盒出现故障，如果利用adb进行调试，只能选择派技术人员提供上门服务。即先将安装有abd的调试用电脑与机顶盒连接在同一局域网，然后再利用adb对机顶盒进行调试。利用adb进行调试，受网络属性的局限性，且需要维护人员提供上门调试服务。

具体实施方式
本发明提供实施例提供了一种调试机顶盒的方法、机顶盒和服务器，解决了远程外网服务器无需先接入到内网，即可远程调试内网的机顶盒的技术问题，实现真正意义上的远程调试机顶盒的技术效果。
图1是一实施例提供的远程调试方法的流程图，本实施例中的方法可适用于对远程的内网中机顶盒进行远程调试的场景，该方法可由远程的外网中机顶盒来执行，如图1所示，本实施例提供的方法可以包括如下步骤：
在步骤110中，基于SSH协议，与服务器建立SSH连接，服务器设置于远程的外网中。
在一个实施例中，机顶盒在远程的内网中，与机顶盒配合使用的遥控器设置有开启远程调试的快捷键，当机顶盒出现故障(非开机故障)，用户有远程调试需求时，在机顶盒开机后按下开启远程调试的快捷键，机顶盒启动远程调试服务，基于SSH协议以及服务器的IP地址，与设置于远程的外网中的服务器建立SSH连接。
需要说明的是，由于远程调试需要root权限，优选的，将实现启动远程调试的功能模块集成到机顶盒的内部系统中，使得用户只需按下远程调试的快捷键即可启用远程调试服务，或者也可以通过其他方式启用远程调试服务。
在步骤120中，接收并执行服务器发送的调试指令。
在一个实施例中，服务器可以通过常规的串口调试工具(如串口调试助手)向机顶盒发送调试指令(如input keyevent KEYCODE_POWER指令)，机顶盒接收并执行该调试指令。
在步骤130中，在执行调试指令期间，按照预设周期，周期性地采集机顶盒的输出数据。
在一个实施例中，预设周期优选为100ms，机顶盒的输出数据优选为截屏图片，还可以包括实时日志文件。机顶盒在执行调试指令期间，每隔100ms对机顶盒的播放画面进行截屏，获得截屏图片，并获得日志文件。
示例性的，在前述按下开启远程调试的快捷键时，机顶盒除了启用远程调试服务外，还同时启用远程传图服务，机顶盒通过远程传图服务，每隔预设时长(如100ms)执行一次截屏抓图操作，并抓取日志文件。
在步骤140中，基于SSH连接，发送输出数据给服务器，使远程服务器根据输出数据，执行后续调试操作。
在一个实施例中，机顶盒基于SSH协议，通过scp(secure copy)命令实时将每次采集到的输出数据发送给远程的服务器，服务器可以进一步将接收的输出数据发送给技术人员的网页客户端，使得技术人员可以通过网页客户端直接看到截屏图片和日志数据，将截屏图片连成一起播放就是机顶盒的播放画面，技术人员根据播放画面分析机顶盒的故障，根据情况执行后续调试操作。
技术人员通过网页客户端除了可以查看机顶盒的截屏图片和日志数据外，还可以通过网页客户端输入调试指令(如input keyevent KEYCODE_POWER指令)，传输到服务器后再发送到机顶盒；技术人员还可以在网页客户端将一些常用按键比如上、下、左、右、确认、数字键等input命令映射成快捷按钮，技术人员只需要点网页客户端上的按钮，网页客户端就会发送input模拟按键命令给服务器，而服务器与机顶盒基于SSH协议相连，所以机顶盒直接收到命令后执行，实现对机顶盒的远程遥控。
综上，在本发明实施例中，通过采取外网服务器基于SSH协议与内网中待调试的机顶盒建立SSH连接，使得内网中的机顶盒可以接收外网服务器发出的调试指令；并且，在调试过程中，通过机顶盒周期性地发送机顶盒输出数据给 远程外网服务器，使得服务器根据输出数据可以更好地执行后续调试操作，以顺利完成对机顶盒的远程调试。解决了远程外网服务器无需先接入到内网，即可远程调试内网的机顶盒的技术问题，实现真正意义上的远程调试机顶盒的技术效果，为用户、售后人员和技术人员带来便捷、实时、高效、低成本的服务体验。
图2是一实施例提供的远程调试方法的流程图，本实施例在上述实施例的基础上，可选的，机顶盒上搭建有第一SSH客户端和第一SSH服务端；
所述与服务器建立SSH连接包括：
通过第一SSH客户端与服务器建立SSH反向隧道；
基于SSH反向隧道，通过第一SSH服务端，接收服务器发出的建立连接请求，与服务器建立SSH连接。
基于上述优化，如图2所示，本实施例提供的远程调试方法，可以包括如下步骤：
在步骤210中，基于SSH协议，通过第一SSH客户端与服务器建立SSH反向隧道。
优选的，所述通过第一SSH客户端与服务器建立SSH反向隧道，包括：
根据服务器的IP地址，通过第一SSH客户端，将机顶盒的第一端口镜像到服务器的第二端口上。
在一个实施例中，远程内网中机顶盒的IP地址为172.28.253.155，包括22端口(即第一端口)，远程外网中服务器的IP地址为192.168.2.230，包括19998端口(即第二端口)，服务器上相应搭建有第二SSH客户端和第二SSH服务端。在机顶盒开机后启动远程调试服务时，机顶盒通过第一SSH客户端主动向服务器的第二SSH服务端发起SSH连接，建立SSH反向隧道，通过端口转发，将服务器的19998端口转发到机顶盒的22端口，即机顶盒的22端口镜像到服务器的19998端口上。机顶盒的第一SSH客户端向服务器发出SSH命令：ssh-R19998：localhost：22 root@192.168.2.230，包括：
root@RD2test：～#ssh-R 19998：localhost：22 root@192.168.2.230
root@19192.168.2.230’s password：

root@RD2TEAM：～#cd/home/caoli/co
code/  config/
如此，机顶盒端就进入了服务器的串口，建立了一个SSH反向隧道，实现从机顶盒到服务器的连接。
需要说明的是，由于SSH反向隧道需要root权限，所以优选通过机顶盒的内置服务来完成建立SSH反向隧道的操作。
在步骤220中，基于SSH反向隧道，通过第一SSH服务端，接收服务器发出的建立连接请求，与服务器建立SSH连接。
在一个实施例中，建立SSH反向隧道后，服务器的第二SSH客户端向机顶盒的第一SSH服务端发起SSH命令：ssh localhost-p 19998，包括：
root@RD2TEAM：～#ssh localhost-p 19998
The authenticity of host ‘[localhost]：19998([127.0.0.1]：19998)’can’t be established.
ECDSA Key fingerprint is bd：81：5a：58：21：58：c2：1c：b5：df：6a：39：f8：4b：75：4a.
Are you sure you want to continue connecting(yes/no)？yes

如此，建立了服务器到机顶盒的22端口的连接，服务器就可以直接串口调试机顶盒了，实现服务器到机顶盒的连接。
在步骤230中，接收并执行服务器发送的调试指令。
在步骤240中，在执行调试指令期间，按照预设周期，周期性地采集机顶盒的输出数据。
在步骤250中，基于SSH连接，发送输出数据给服务器，使远程服务器根据输出数据，执行后续调试操作。
综上，在本发明实施例中，通过采取外网服务器基于SSH协议与内网中待调试的机顶盒建立SSH隧道及SSH连接，使得内网中的机顶盒可以接收外网服务器发出的调试指令；并且，在调试过程中，通过机顶盒周期性地发送机顶盒输出数据给远程外网服务器，使得服务器根据输出数据可以更好地执行后续调试操作，以顺利完成对机顶盒的远程调试。解决了远程外网服务器无需先接入到内网，即可远程调试内网的机顶盒的技术问题，实现真正意义上的远程调试机顶盒的技术效果，为用户、售后人员和技术人员带来便捷、实时、高效、低成本的服务体验。

优选的，所示通过第二SSH服务端与机顶盒建立SSH反向隧道，包括：
