27、electron 开启本地http服务

electron 开启本地http服务，让第三方可以直接通过webapi的方式访问

1、新建server.js

 1 const os = require('os');
 2 const http = require('http');
 3 
 4 
 5 let server;
 6 
 7 function openServer() {
 8     // 防止重复开启
 9     closeServer();
10 
11     // 获取本机的局域网IP和自定义端口
12     let SERVER_PORT = 65526;
13     let SERVER_IP = getServerIp(); //返回127.0.0.1访问的直接http://localhost:65526
14 
15     server = http.createServer();
16     server.on('request',(req,res)=>{
17         res.writeHead(200,{ "Content-Type": "application/json;charset=utf-8", "access-control-allow-origin": "*" });
18 
19         // 监听 '/api/authentication'
20         if(req.method === "POST" && req.url ==="/api/authentication"){
21             let context = {
22                 code: 200,
23                 data: { type: 'Hello World!' }
24               }
25               res.end(JSON.stringify(context));
26         }
27         else if(req.method ==="GET"){
28             let context = {
29                 code: 200,
30                 data: { type: 'GET' }
31               }
32               res.end(JSON.stringify(context));
33               //res.end(test());
34         }
35     });
36 
37     // 返回端口开启结果
38     return new Promise((resolve,reject)=>{
39         server.listen(SERVER_PORT,SERVER_IP,()=>{
40             // 服务器正确开启
41             resolve(`服务器开启成功，服务器地址: http://${SERVER_IP}:${SERVER_PORT}`)
42         });
43         server.on("error",(err)=>{
44             if(err.code === 'EADDRINUSE'){
45                 reject(`端口:${SERVER_PORT}被占用,请更换占用端口`)
46             }
47         });
48 
49     });
50 
51 }
52 
53 function closeServer(){
54     server && server.removeAllListeners();
55     server && server.close(()=>{
56         console.log("服务接口关闭");
57     });
58 }
59 
60 
61 // 获取本机的局域网IP
62 function getServerIp() {
63     return "127.0.0.1";  //
64 
65     let interfaces = os.networkInterfaces();
66     for (let devName in interfaces) {
67       let iface = interfaces[devName];
68       for (let i = 0; i < iface.length; i++) {
69         let alias = iface[i];
70         if (alias.family === 'IPv4' && alias.address !== '127.0.0.1' && !alias.internal) {
71           return alias.address;
72         }
73       }
74     }
75   }
76 
77   
78   module.exports = {   //注意node的导出方式是module.exports 或exports
79     openServer,
80     closeServer
81   }
View Code

2、在index.js里面引入server.js并开启服务

let {openServer} = require("./server.js");   //开启本地http服务
//开启服务
    openServer().then(res=>{
        console.log("返回:"+res);
    }).catch((e)=>{
        dialog.showErrorBox("提示信息",e);
    });

3、启动程序，打开浏览器访问http://localhost:65526/，post的方式通过postman调试也正常
