如何将参数传递给firebase的云函数

Question

我正在使用 Android。

用户登录firebase后，如何根据账号找回firestore中的用户信息？

我的功能在firebase的云功能中。 我的代码如下：

mFunctions.getHttpsCallable("getInfo").call()
            .continueWith(new Continuation<HttpsCallableResult, Object>() {
                @Override
                public String then(@NonNull Task<HttpsCallableResult> task) throws Exception {

                    Log.d("-----TEST-----", "BEGIN000");
                    Object result =  task.getResult().getData();
                    Log.d("-----TEST-----", "SUCCESS");
                    self_tel.setText((Integer) result);
                    return (String) result;
                }
            }).addOnCompleteListener(new OnCompleteListener<Object>() {
        @Override
        public void onComplete(@NonNull Task<Object> task) {
            if (!task.isSuccessful()) {
                Exception e = task.getException();
                if (e instanceof FirebaseFunctionsException) {
                    FirebaseFunctionsException ffe = (FirebaseFunctionsException) e;
                    FirebaseFunctionsException.Code code = ffe.getCode();
                    Object details = ffe.getDetails();
                }

                // [START_EXCLUDE]
                Log.w("test", "addMessage:onFailure", e);
                //showSnackbar("An error occurred.");
                return;
                // [END_EXCLUDE]
            }
            String result = (String) task.getResult();
            Log.d("-----TEST-----", "SUCCESS1");

        }
    });

如果您在使用 firebase-firestore 时需要帮助，可以使用内置助手。 转到 Tools -> Firebase 并按照说明进行操作。

您可以使用 HashMap 将参数传递给 firebase 函数

// Create the arguments to the callable function.
Map<String, Object> data = new HashMap<>();
data.put("text", text);
data.put("push", true);

并使用.call(data)传递它

// Create the arguments to the callable function.
Map<String, Object> data = new HashMap<>();
data.put("text", text);
data.put("push", true);

return mFunctions
        .getHttpsCallable("getInfo")
        .call(data)
        .continueWith(new Continuation<HttpsCallableResult, String>() {
            @Override
            public String then(@NonNull Task<HttpsCallableResult> task) throws Exception {
                // This continuation runs on either success or failure, but if the task
                // has failed then getResult() will throw an Exception which will be
                // propagated down.
                String result = (String) task.getResult().getData();
                return result;
            }
        });
