Lua_Http_GetHttpData(url)

获取指定网址的数据

参数	说明	类型
url	获取数据的网址	string

local HttpData = Lua_Http_GetHttpData('https://luascript.alcedo.top/')

推荐用于获取json等网络接口数据，json可使用lua的json库解析成table，例如

注意：此段为节选代码，仅供参考，请不要直接使用

json = require "nativePC/LuaScript/Common/json"
function run ()
    local GetHttp = Lua_Http_GetHttpData('https://luascript.alcedo.top/link/?link=ad9582c0-15ed-4e65-a8e8-ac188622f8ae')
    local HttpData = json.decode(GetHttp)
    for _, Data in pairs(HttpData) do
        local LuaCode = Lua_Http_GetHttpData(Data.LuaCode)
    end
end

Lua_WS_LinkWSServer(wsurl)

链接到指定的websocket服务器

参数	说明	类型
wsurl	服务器ws地址	string

Lua_WS_LinkWSServer('ws://localhost:3010/api')

以下为一个聊天mod的演示程序，包含websocket的基本使用方式演示

server.js

/*
  部署:
    1. 按照node和npm/yarn
    2. 在服务脚本目录下执行npm install ws或yarn add ws
    3. 执行node server.js命令
*/
"use strict";
var WebSocketServer = require('ws').Server;
var http = require('http');

var server = http.createServer();
var wss = new WebSocketServer({server: server, path: '/foo'});
wss.broadcast = function broadcast(ws) {
  wss.clients.forEach(function each(client) {
    client.send(ws.msg);
  });
};
wss.on('connection', function(ws) {
    console.log('/foo connected');
    ws.on('message', function(data, flags) {
        if (flags != undefined && flags.binary) { return; }
        console.log('>>> ' + data);
        wss.broadcast({
          msg:data
        });
    });
    ws.on('close', function() {
      console.log('Connection closed!');
    });
    ws.on('error', function(e) {
    });
});
server.listen(3010);
console.log('服务已启动，端口：3010');
