[英]Using Websocket with express and Nodejs not working
I have this code which I am using for my express server.我有这段代码用于我的快递服务器。 The server works when I access the routes over http however when I try to connect to it over wss it doesnt work.
当我通过 http 访问路由时服务器工作,但是当我尝试通过 wss 连接它时它不起作用。 What am I doing wrong?
我究竟做错了什么?
const morgan = require("morgan");
const cors = require("cors");
const passport = require("passport");
const localStrategy = require("./auth/local");
const jwtStrategy = require("./auth/jwt");
const expressValidator = require("express-validator");
const config = require("./config");
const app = express();
const http = require("http").Server(app);
const io = require("socket.io")(http);
app.use(cors());
app.use(express.json());
app.use(expressValidator());
app.use(morgan("common"));
app.use(passport.initialize());
passport.use(localStrategy);
passport.use(jwtStrategy);
require("./routes")(app);
io.on("connect_error", (err) => {
console.log(`connect_error due to ${err.message}`);
});
io.on("connection", (socket) => {
console.log("a user connected", socket);
});
http.listen(config.port);
module.exports = app;
Try using ws:
in place of wss:
for a quick fix.尝试使用
ws:
代替wss:
进行快速修复。
wss:
is the TLS-secured version of ws:
, analogous to https:
and http:
. wss:
是ws:
: 的 TLS 安全版本,类似于https:
和http:
。 In fact, websocket connections to a server begin their lives as http / https connections.实际上,与服务器的 websocket 连接开始于 http / https 连接。 They're then "upgraded" to websocket connections by the websocket protocol.
然后通过 websocket 协议将它们“升级”到 websocket 连接。
So, to get wss:
to work on that server of yours, start by getting https:
working for the express webserver part.因此,要获得
wss:
在您的服务器上工作,首先要获得https:
为 express webserver 部分工作。 It's the https server behind express that will also handle the connections to be upgraded. Express 后面的 https 服务器也将处理要升级的连接。
