java - Android Firebase REST问题

出于某种原因，我无法将数据推送到我的firebase数据库。我正试着用凌空抽射打给我的数据库。你认为我做错了什么？
我收到的问题：

12-23 19:16:43.026  15428-16461/me.anuraag.barter E/Volley﹕ [7289] BasicNetwork.performRequest: Unexpected response code 400 for https://barter.firebaseio.com/.json
12-23 19:16:43.028  15428-15428/me.anuraag.barter I/Error.Response﹕ com.android.volley.ServerError

代码：

public void firebaseSignUp(String emails){
    final String emailed = emails;
    RequestQueue queue = Volley.newRequestQueue(getActivity());
    String url ="https://barter.firebaseio.com/.json";

    StringRequest postRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
        @Override
        public void onResponse(String response) {
            Log.i("Repsponse",response);
        }
    },new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
           Log.i("Error.Response", error.toString());

        }
    }
    ) {
        protected Map<String, String> getParams() {
            Map<String, String> params = new HashMap<String, String>();
            params.put("email", emailed);
            return params;
        }
    };
    queue.add(postRequest);
}

最佳答案

不要自己做。使用Firebase API为per their examples处理所有这些。
请确保您已先与firebase注册。然后将此添加到您的POST中的依赖关系中：
编译'com.firebase:firebase客户端android:2.0.3+'
然后，你可以做如下事情：

Firebase usersRef = new Firebase("firebase.url.your/personal/dir").child("someChild");

Map<String, Object> users = new HashMap<String, Object>();
users.put("Dogs rule", someObjectWithAccessors);
users.put("Cats drewl", someOtherObjectWithAccessors);

usersRef.setValue(users);

然后，对于save，您可以执行以下操作：

// Attach an listener to read the data at our posts
usersRef.addValueEventListener(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot snapshot) {
        Log.d(TAG, snapshot.getKey() + " received from firebase");
    }

    @Override
    public void onCancelled(FirebaseError firebaseError) {
        Log.w(TAG, "The read failed: " + firebaseError.getMessage());
    }
 });
