腾讯云云游戏Demo 后端与云 API 对接示例（Node.js）_音视频解决方案_同尘科技

步骤1：环境部署

cloudapi.js 是 Node.js 版的云 API 调用实例，自行安装 Node.js 运行环境。将 cloudapi.js 中的 SecretId 和 SecretKey，替换成您的腾讯云账号下的 云 API 密钥 信息。cloudapi.js 示例代码如下：

var express = require('express');var router = express.Router();// import client modelsvar tencentcloud = require('tencentcloud-sdk-nodejs');const GsClient = tencentcloud.gs.v20191118.Client;
// tencent cloud api secret id and key, could be found here: https://console.cloud.tencent.com/cam/capivar secretId = 'your secretId';var secretKey = 'your secretKey';
// tencent cloud api client profileconst client = new GsClient({    credential: {        secretId,        secretKey,    },    region: "ap-shanghai",// cloud api region, for example: ap-shanghai, ap-guangzhou, ap-chengdu, ap-beijing    profile: {        signMethod: "TC3-HMAC-SHA256",// signature algorithm        httpProfile: {            reqMethod: "POST",            reqTimeout: 30,        },    },});
var paramsVerify = (req, res, next) => {    try {        if (!req.body || typeof ("") == typeof (req.body)) {            throw 'request body is null or did not parse as json';        }
        ["Appid", "Action", "Version", "Region"].forEach((item, _) => {            if (item in req.body) {                throw `${item} is not required`;            }        });    } catch (err) {        res.json({ code: -1, data: err });        return;    }    next();};
// support forward proxyvar getClientIp = (req) => {    var ips = req.headers['x-forwarded-for'] ||        req.headers['x-real-ip'] ||        req.connection.remoteAddress ||        req.socket.remoteAddress ||        req.connection.socket.remoteAddress;    return ips ? ips.split(',')[0].trim() : "";};
// API for get client WAN iprouter.get('/get_wan_ip', (req, res, next) => {    var clientIp = getClientIp(req).replace(/::ffff:/, '');// ipv4-over-ipv6 to ipv4    var data = JSON.stringify({ cip: clientIp });    var body = `var returnCitySN = ${data};`;    res.end(body);});
// try to lock an instancerouter.post('/TrylockWorker', paramsVerify, (req, res, next) => {    var clientInfo = req.body;
    client.TrylockWorker(clientInfo).then((response) => {        // normally        console.log(response);        res.json({ code: 0, data: response });    }, (err) => {        // error        console.log(err);        res.json({ code: -1, data: err });    });});
// connect to locked instancerouter.post('/CreateSession', paramsVerify, (req, res, next) => {    var clientInfo = req.body;
    client.CreateSession(clientInfo).then((response) => {        // normally        console.log(response);        res.json({ code: 0, data: response });    }, (err) => {        // error        console.log(err);        res.json({ code: -1, data: err });    });});
// release instancerouter.post('/StopGame', paramsVerify, (req, res, next) => {    var clientInfo = req.body;
    client.StopGame(clientInfo).then((response) => {        // normally        console.log(response);        res.json({ code: 0, data: response });    }, (err) => {        // error        console.log(err);        res.json({ code: -1, data: err });    });});

module.exports = router;

步骤2：创建 express 项目

使用 express-generator 初始化一个 express 项目。

express myprojnpm i

步骤3：安装依赖库

npm install --save express tencentcloud tencentcloud-sdk-nodejs

步骤4：调用云 API

参考示例代码编写 cloudapi.js，修改 app.js，在后面加入一行。

app.use('/cloudapi', require('./cloudapi.js'));

步骤5：运行服务

npm run

步骤6：启动云游戏

网页端发送 try_lock 请求，锁定机器成功后，再调用 get_signature，返回值获得 ServerSession 字段，然后调用 TCGSDK.start(ServerSession) 接口启动云游戏。
