我當時在使用AWS託管服務時首先爲我的應用程序使用了Parse，但後來當Parse關閉其服務時，我將其移至back4app。我的登錄和註冊過去與以前的Parse項目一起工作良好，但現在無論何時我使用我的back4app項目登錄或註冊，我都會收到錯誤com.parse.ParseRequest $ ParseRequestException：未授權。我嘗試過使用客戶端密鑰和主密鑰，但他們似乎根本沒有工作。
這裏是我的註冊代碼：
public void clickSignup(View view) {
ParseUser.logOut();
loader = (ProgressBar) findViewById(R.id.loadingBar);
loader.setVisibility(View.VISIBLE);
ParseQuery checkAvailability = ParseUser.getQuery();
textUser = (EditText) findViewById(R.id.textUser);
textPass = (EditText) findViewById(R.id.textPass);
if (textUser.getText().toString().isEmpty() || textPass.getText().toString().isEmpty()) {
loader.setVisibility(View.INVISIBLE);
Toaster("Enter a valid username/password");
} else if (textUser.getText().length() < 4){
Toaster("Username must have four or more characters");
loader.setVisibility(View.INVISIBLE);
} else if (textPass.getText().length() < 6) {
Toaster("Password mush have atleast six or more characters");
loader.setVisibility(View.INVISIBLE);
}else{
String user = textUser.getText().toString();
Log.i("user", user);
checkAvailability.whereEqualTo("username" , user);
checkAvailability.findInBackground(new FindCallback<ParseUser>() {
@Override
public void done(List<ParseUser> objects, ParseException e) {
if (e == null && objects.size() == 1){
loader.setVisibility(View.INVISIBLE);
Toaster("This username already exists");
} else if (e == null && objects.size() != 1){
loader.setVisibility(View.INVISIBLE);
ParseUser newUser = new ParseUser();
newUser.setUsername(textUser.getText().toString());
newUser.setPassword(textPass.getText().toString());
newUser.signUpInBackground(new SignUpCallback() {
@Override
public void done(ParseException e) {
Log.i("S", "Seucbbkw");
Log.i("e", e.toString());
if (e == null){
Intent intent = new Intent(getApplicationContext(), LoggedIn.class);
intent.putExtra("Username",textUser.getText().toString());
startActivity(intent);
Toaster("Signup Successful");
}
}
});
} else {
Log.i("Objects", e.toString());
}
}
});
}
}
，這裏是我的登入碼：
public void clickSignin(View view){
ParseUser.logOut();
textUser = (EditText) findViewById(R.id.textUser);
textPass = (EditText) findViewById(R.id.textPass);
loader.setVisibility(View.VISIBLE);
if (textUser.getText().toString().isEmpty() || textPass.getText().toString().isEmpty()) {
loader.setVisibility(View.INVISIBLE);
Toaster("Enter a valid username/password");
} else {
final ParseQuery logInner = ParseUser.getQuery();
logInner.whereEqualTo("username", textUser.getText().toString());
ParseUser.logInInBackground(textUser.getText().toString(), textPass.getText().toString(), new LogInCallback() {
@Override
public void done(ParseUser user, ParseException e) {
if (e == null) {
Intent intent = new Intent(getApplicationContext(), LoggedIn.class);
intent.putExtra("Username",textUser.getText().toString());
startActivity(intent);
Toaster("Login Successful");
loader.setVisibility(View.INVISIBLE);
} else {
Toaster("Invalid username or password");
Log.i("Error", e.toString());
loader.setVisibility(View.INVISIBLE);
}
}
});
}
}
