使用Node.js时出现Android截击post错误
我知道这个问题可能被问了很多次,但似乎没有一个解决方案适合我。在我的android截击post请求中,我传入用户名和密码,但每次单击“登录”时,它都会显示“无效用户名和密码”,即使凭据是正确的,邮递员也可以使用。下面是我的代码: 登录Node.js使用Node.js时出现Android截击post错误,android,node.js,android-volley,Android,Node.js,Android Volley,我知道这个问题可能被问了很多次,但似乎没有一个解决方案适合我。在我的android截击post请求中,我传入用户名和密码,但每次单击“登录”时,它都会显示“无效用户名和密码”,即使凭据是正确的,邮递员也可以使用。下面是我的代码: 登录Node.js router.post('/login', function(req,res,next){ var user = { username: req.body.username, password: req.body.password

任何帮助都将不胜感激,请提前感谢。您没有在请求正文中发送用户名和密码:
JsonObjectRequest rq = new JsonObjectRequest(Request.Method.POST, url, null, new Response.Listener<JSONObject>() {
JsonObjectRequest rq=newjsonobjectrequest(Request.Method.POST,url,null,new Response.Listener()){
创建正文并根据请求设置:
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>() {
JSONObject body=new JSONObject();
body.put(“用户名”,uname);
body.put(“密码”,upass);
JsonObjectRequest rq=新的JsonObjectRequest(Request.Method.POST、url、body、new Response.Listener()){

我已经修复了,原来是电子邮件响应为空并引发异常,多亏了Tiago Ribeiro,代码终于可以工作了,下面是更新的代码
Login.js:
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],
