[英]WebSocket connection between reactjs Client and flask-socketio Server doesn't open
[英]Can't make a websocket connection between react client and express server
我正在嘗試使用 websockets 在反應客戶端和快速服務器之間建立連接。 每次我嘗試這個時,我都會收到一個錯誤。 我想我錯過了一些東西。
服務器代碼:
var http = require('http');
var ws = require('ws');
var theHttpServer = http.createServer();
var theWebSocketServer = new ws.Server({
server: theHttpServer,
verifyClient: true
});
theHttpServer.on('request', app);
theHttpServer.listen(9000,
function () {
console.log("The Server is lisening on port 9000.")
});
theWebSocketServer.on('connection', function connection(msg) {
console.log("CONNECTION CREATED");
websocket.on('message', function incoming(message) {
});
});
客戶端代碼:
let wsConnection = new WebSocket("ws://localhost:9000");
wsConnection.onopen = function(eventInfo) {
console.log("Socket connection is open!");
}
錯誤:
if (!this.options.verifyClient(info)) 返回 abortHandshake(socket, 401); ^
類型錯誤:this.options.verifyClient 不是函數
您將verifyClient
作為布爾值傳遞,而不是函數。 您可能想要做的是將其更改為:
function verifyClient(info) {
// ...Insert your validation code here
};
var theWebSocketServer = new ws.Server({
server: theHttpServer,
verifyClient: verifyClient
});
