如何将Firebase与Spring Boot REST应用程序一起使用？

Question

我有一个Spring Boot REST应用程序，它依赖于Firebase中完成的身份验证。

在客户端，Firebase生成令牌，借此在Spring Boot中，我需要验证UID。

但是代码处于回调模式，因此如何实现该函数以使其能够完成任务？

@RequestMapping(value = "/api/restCall", method = RequestMethod.POST, 
             consumes = "application/json", produces = "application/json")
public Object restCall(@RequestBody Parameters requestBody) throws Exception {
    String idToken = requestBody.getToken();
    Task<FirebaseToken> task = FirebaseAuth.getInstance().verifyIdToken(idToken)
            .addOnSuccessListener(new OnSuccessListener<FirebaseToken>() {
            @Override
                public void onSuccess(FirebaseToken decodedToken) {
                    String uid = decodedToken.getUid();
                }
            });
    return "???"; // what return here?
}

之后如何返回onSuccess？DeferredResult？

Answer 1

这是我自己尝试回答我自己的问题

@RequestMapping(value = "/api/restCall", method = RequestMethod.POST, consumes = "application/json", produces = "application/json")
public Object restCall(@RequestBody Parameters requestBody,@RequestHeader(value = FIREBASETOKEN, required = true) String idToken) throws Exception {

    // idToken comes from the HTTP Header
    FirebaseToken decodedToken = FirebaseAuth.getInstance().verifyIdTokenAsync(idToken).get();
    final String uid = decodedToken.getUid();

    // process the code here
    // once it is done
    return object;

}

您也可以尝试以下代码

FirebaseAuth.getInstance().deleteUser(uid);
System.out.println("Successfully deleted user.");
