我正在尝试Firebase示例“使用Android中的电子邮件链接对Firebase进行身份验证”。该链接就是该示例。 https://firebase.google.com/docs/auth/android/email-link-auth
我已完成sendSignInLink到电子邮件的操作。
但是在“验证链接并登录”部分中,我不了解代码。 在这一部分
Intent intent = getIntent();
String emailLink = intent.getData().toString();
可理解的是,intent.getData()。toString();使错误nullpointexception ..... 在该Firebase示例中,没有详细的解释或示例代码。
ActionCodeSettings actionCodeSettings =
ActionCodeSettings.newBuilder()
// URL you want to redirect back to. The domain (www.example.com) for this
// URL must be whitelisted in the Firebase Console.
.setUrl("https://www.example.com/finishSignUp?cartId=1234")
// This must be true
.setHandleCodeInApp(true)
.setIOSBundleId("com.example.ios")
.setAndroidPackageName(
"com.example.android",
true, /* installIfNotAvailable */
"12" /* minimumVersion */)
.build();
FirebaseAuth auth = FirebaseAuth.getInstance();
auth.sendSignInLinkToEmail(email, actionCodeSettings)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if (task.isSuccessful()) {
Log.d(TAG, "Email sent.");
}
}
});
至此,一切都成功了。
Intent intent = getIntent();
String emailLink = intent.getData().toString();
// Confirm the link is a sign-in with email link.
if (auth.isSignInWithEmailLink(emailLink)) {
// Retrieve this from wherever you stored it
String email = "someemail@domain.com";
// The client SDK will parse the code from the link for you.
auth.signInWithEmailLink(email, emailLink)
.addOnCompleteListener(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Log.d(TAG, "Successfully signed in with email link!");
AuthResult result = task.getResult();
// You can access the new user via result.getUser()
// Additional user info profile *not* available via:
// result.getAdditionalUserInfo().getProfile() == null
// You can check if the user is new or existing:
// result.getAdditionalUserInfo().isNewUser()
} else {
Log.e(TAG, "Error signing in with email link", task.getException());
}
}
});
}
