(HTML/Js) 使用提示和承諾的身份驗證

Question

我在下面有一些代碼：

async function authenticateUser() {
        let authenticated = false;
        socketTx = io();
        socketRx = io.connect();

        var user = prompt("Please enter username", "");
        var pass = prompt("Please enter your password", "");

        socketTx.emit('authChannel', {username: user, password: pass});

        let promise = new Promise((resolve, reject) => {
              socketRx.on('authChannel', function(auth) {
                //console.log(auth);
                resolve(auth); 
              });
        });

        authenticated = await promise;
        console.log(authenticated)
        if (authenticated == false) {
          user;
          pass;
        } else {authenticated == true}
      }

socketTx將user / pass數據發送到服務器以在Node.js進行 PAM 身份驗證。 socketRx接收用戶是否通過身份驗證的true / false 。

期望的行為是提示向用戶發送垃圾郵件，直到提供正確的“登錄”信息。 我以為我在驗證身份驗證為假后再次調用變量user / pass時捕獲了這種行為，但提示不會顯示第二次（或更多）次。 我可以確認我在console.log(authenticated)收到了正確的信息。

有什么明顯的我遺漏了嗎？

提前致謝。

根據評論：

async function authenticateUser() {
        let authenticated = false;
        socketTx = io();
        socketRx = io.connect();

        var user = prompt("Please enter username", "");
        var pass = prompt("Please enter your password", "");

        socketTx.emit('authChannel', {username: user, password: pass});

        let promise = new Promise((resolve, reject) => {
              socketRx.on('authChannel', function(auth) {
                //console.log(auth);
                resolve(auth); 
              });
        });

        authenticated = await promise;
        console.log(authenticated)
        if (authenticated == false) {
          authenticateUser(); // recall method
        } else {authenticated == true}
      }
