朋友，我想把我的应用程序连接到套接字。IO node.js web服务器，这是我的移动端代码:
private Socket mSocket;
try {
IO.Options options = new IO.Options();
options.forceNew = true;
options.transports = new String[]{WebSocket.NAME};
mSocket = IO.socket("https://taxiappapi.webfumeprojects.online", options);
mSocket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {
@Override
public void call(Object... args) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, "Connected", Toast.LENGTH_SHORT).show();
}
});
Log.d(TAG, "Socket checkConnection: connect 1 " + args[0]);
}
});
mSocket.on(Socket.EVENT_CONNECT_ERROR, new Emitter.Listener() {
@Override
public void call(Object... args) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, "Connection error!", Toast.LENGTH_SHORT).show();
}
});
Log.d(TAG, "Socket checkConnection: onConnectError 1 " + args[0]);
}
});
mSocket.on(Socket.EVENT_CONNECT_TIMEOUT, new Emitter.Listener() {
@Override
public void call(Object... args) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, "Connection timeout!", Toast.LENGTH_SHORT).show();
}
});
Log.d(TAG, "Socket checkConnection: onConnectTimeOut 1 " + args[0]);
}
});
mSocket.connect();
} catch (URISyntaxException e) {
e.printStackTrace();
}
const express = require("express");
var ObjectId = require('mongoose').Types.ObjectId;
const ioAuth = require("../../middleware/socketAuth");
const Driver = require("../../model/driver/userDriver");
const app = express.Router();
const http = require('http').Server(app);
const io = require('socket.io')(http, {
cors: {
origin: "http://localhost:4200",
methods: ["GET", "POST"]
}
});
io.on('connection', (socket) => {
console.log('a user connected');
// Auth
// io.use((socket, next) => {
// ioAuth(socket, next);
// // const token = socket.handshake.auth.token;
// // console.log(token);
// // if(token == 'abc'){

socket.on("online", (arg) => {
if(ObjectId.isValid(arg.driver)){
let isOnline = arg.status;
Driver.findByIdAndUpdate(arg.driver, {isOnline: isOnline}, function(err, data){
if(err) console.log(err); // world.
console.log(data); // world.
console.log(arg.driver + ' now is ' + isOnline); // world.
socket.emit(arg.driver, 'My New Location: ' + arg.status);
});
}else{
console.log('not an object ID', arg)
}
});
socket.on("MyLocation", (arg) => {
if(ObjectId.isValid(arg.driver)){
let lat = arg.lat;
let lng = arg.lng;
let location = {
type: "Point",
coordinates: [
lat, lng
]
};
Driver.findByIdAndUpdate(arg.driver, {location});
console.log(arg.driver + ' now is ' + arg.status); // world.
socket.emit(arg.driver, arg);
}else{
console.log('not an object ID')
}
});
socket.on("MyID", (arg) => {
console.log(arg); // world
});
});
http.listen(3100, () => {
console.log('listening on *:3100');
});
// // server.listen(3100);
module.exports = app;
当我运行我的移动应用程序项目时，我得到了这个错误:
io.socket.engineio.client.EngineIOException: websocket error
我也搜索了很多，我在清单文件中添加了互联网权限:
<uses-permission android:name="android.permission.INTERNET" />
我在manifest文件和应用程序标签中添加了usesCleartextTraffic:
<application
android:usesCleartextTraffic="true"...
这是我所有的logcat:

但是我仍然得到这个错误，请帮助我。
编辑URL为http://taxiappapi.webfumeprojects.online
将HTTPS改为HTTP我希望它有助于问题不是那么清楚，但尝试这个，告诉我如果它的工作🖤
试着把这个对象放到
io.on('connection', (socket) => .....
(async () => {
io.on('connection', (socket) =>
//And the http.listen too.
})()
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" >
</uses-permission
将此添加到您的清单
和请张贴所有的logcat消息
