使用Node.js時Android-volley發佈錯誤

我知道這個問題可能已被多次詢問，但沒有一個解決方案似乎適用於我。在我的android volley post請求中，我傳遞了用戶名和密碼，但每次我單擊登錄時，它總是會說'無效的用戶名和密碼'，即使憑據是正確的，並且郵遞員也能正常工作。在這裏我下面的代碼：使用Node.js時Android-volley發佈錯誤

登錄的Node.js在客戶端（安卓）

router.post('/login', function(req,res,next){ 
    var user = { 
    username: req.body.username, 
    password: req.body.password 
    }; 

    connection.query("SELECT id, fullname, username, email_address, createdAt FROM users WHERE username=? OR email_address=? AND password=? LIMIT 1",[user.username, user.username, user.password], function(err, rows, field){ 
     if(err) throw err; 
     if(rows.length > 0){ 
     res.json({ 
      success: '1', 
      message: 'Login Successful', 
      id: rows[0], 
      fullname: rows[1], 
      username: rows[2], 
      email: rows[3], 
      createdAt: rows[4] 
     }); 
     }else{ 
     res.json({ 
      success: '0', 
      message: 'Invalid username or password' 
     }); 
     } 
    });

任何幫助將非常感激，謝謝提前。

我已經固定它，原來它是電子郵件的答覆是空和投擲例外，並感謝蒂亞戈裏貝羅代碼終於工作，這裏的更新代碼

router.post('/login', function(req,res,next){ 
    function encrypt(text){ 
     var cipher = crypto.createHash('sha1') 
      .update(text) 
      .digest('hex'); 
     return cipher; 
    } 
    var uPassword = encrypt(req.body.password.toString()); 
    var user = { 
    username: req.body.username, 
    password: uPassword 
    }; 

    connection.query("SELECT id, fullname, username, email_address, createdAt FROM users WHERE (username=? OR email_address=?) AND password=? LIMIT 1",[user.username, user.username, user.password], function(err, rows, field){ 
     if(err) throw err; 
     if(rows.length > 0){ 
     res.json({ 
      success: 1, 
      message: 'Login Successful', 
      id: rows[0], 
      fullname: rows[1], 
      username: rows[2], 
      email_address: rows[3], 
      createdAt: rows[4] 
     }); 
     }else{ 
     res.json({ 
      success: 0, 
      message: 'Invalid username or password' 
     }); 
     }

你不是在發送請求正文中的用戶名和密碼：

JsonObjectRequest rq = new JsonObjectRequest(Request.Method.POST, url, null, new Response.Listener<JSONObject>() {

創建身體和要求設置：

JSONObject body = new JSONObject(); 
body.put("username", uname); 
body.put("password", upass); 

JsonObjectRequest rq = new JsonObjectRequest(Request.Method.POST, url, body, new Response.Listener<JSONObject>() {
