1. 下载安装sekiro
下载地址: https://oss.virjar.com/sekiro/sekiro-demo，选择最新版的下载即可
下载完成以后解压zip文件出现如下三个文件夹:

进入bin文件夹中,如果是windows系统点击sekiro.bat文件，如果是linux系统运行sekiro.sh文件即可运行sekiro
2. sekiro入门使用
将以下代码在浏览器控制台进行注入使用

以上代码要点解析:
(1) var client = new SekiroClient("wss://sekiro.virjar.com/business-demo/register?group=ws-group-2&clientId=" + guid()); 这一行中的url是websocket服务地址,其中根据是否使用加密套接字的情况使用wss或者是ws.
域名地址根据服务部署情况进行修改，可以使用自己的域名或者是内网ip。如果是在本地部署一般使用127.0.0.1即可，端口号默认是5620.
group=ws-group-2这个是服务的组名，可以根据需求创建多个组名，一般根据数据获取的需求设置组名
(2) client.registerAction("clientTime", function (request, resolve, reject) { resolve("SekiroTest：" + new Date()); });
client.registerAction方法的第一个参数是客户端请求sekiro服务时的action参数，可以自己命名。
resolve("SekiroTest：" + new Date()); 方法中的内容就是返回的数据，即客户端请求时所获取到的数据.
(3) 使用方式为: 将浏览器中的代码复制下载添加到resolve函数的上方，之后将所有代码在浏览器控制台执行，之后使用python去请求sekiro服务，请求地址格式为http://127.0.0.1:5620/business-demo/invoke?group=nb_match5&action=getData，其中127.0.0.1:5620是自己设置的服务地址，group是new SekiroClient中的group，action是registerAction中的第一个参数名，响应值就是resolve中的数据
