Android获得唯一的FireBase令牌并使用云功能进行身份验证

启动firebase函数1.0+,有两种HTTP函数可用于Android应用程序。

1. 直接调用函数。通过 functions.https.onCall
2. 通过HTTP请求调用函数。通过 functions.https.onRequest

我建议你用 onCall 作为函数的端点,并使用 FirebaseFunctions .这样,您就不需要获取FireBaseUser令牌,因为当您使用 firebase函数 .

记住,typescript只是javascript的超集。我仍将在node.js中给出示例,但建议您在typescript中键入JavaScript代码。

例子

index.js(CloudFunctions端点)

exports.importantfunc = functions.https.onCall((data, context) => {
   // Authentication / user information is automatically added to the request.
   if (!context.auth) {
       // Throwing an HttpsError so that the client gets the error details.
       throw new functions.https.HttpsError('not-authorised', 
                         'The function must be called while authenticated.');
   }

   const uid = context.auth.uid;
   const email = context.auth.token.email;

   //Do whatever you want
});

我的片段.java

//Just some snippets of code examples
private void callFunction() {
    FirebaseFunctions func = FirebaseFunctions.getInstance();
    func.getHttpsCallable("importantfunc")
            .call()
            .addOnCompleteListener(new OnCompleteListener<HttpsCallableResult>() {

                @Override
                public void onComplete(@NonNull Task<HttpsCallableResult > task) {
                    if (task.isSuccessful()) {
                         //Success
                    } else {
                         //Failed
                    }
                }
            });
}
