客户端代码:
let wsConnection = new WebSocket("ws://localhost:9000");
wsConnection.onopen = function(eventInfo) {
console.log("Socket connection is open!");
}
错误:
如果(!this.options.verifyClient(info))返回abortHandshake(套接字,401);

TypeError:this.options.verifyClient不是一个函数您要传递的
verifyClient
不是一个函数,而是一个布尔值。您可能希望将此更改为:
function verifyClient(info) {
// ...Insert your validation code here
};
var theWebSocketServer = new ws.Server({
server: theHttpServer,
verifyClient: verifyClient
});
我完全删除了“verifyClient:true”部分。现在它工作得很好!
