小编Gau*_*rma的帖子

我正在使用FirebaseAuth通过FB登录用户.这是代码:

private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
private CallbackManager mCallbackManager;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());

    // Initialize Firebase Auth
    mAuth = FirebaseAuth.getInstance();

    mAuthListener = firebaseAuth -> {
        FirebaseUser user = firebaseAuth.getCurrentUser();
        if (user != null) {
            // User is signed in
            Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
        } else {
            // User is signed out
            Log.d(TAG, "onAuthStateChanged:signed_out");
        }

        if (user != null) {
            Log.d(TAG, "User details : " + user.getDisplayName() + user.getEmail() + "\n" + user.getPhotoUrl() + …

我已经经历了很多帖子,但没有找到任何能够有效甚至正确回答问题的答案.我最接近的是如何在将联系信息加载到listview时避免重复的联系人姓名(数据)？但这有太大的开销.有没有更简单或更有效的方法来解决这个问题？

我按照本教程创建了自定义地图样式

我现在面临的问题是我想在2D视图中显示地图而不是默认的地球3D视图我不想启用指南针,我相信你可以在两个视图之间切换.

如果您可以分享有关此信息的任何信息,那将非常有用.

谢谢

I just got introduced to the JWT and wanted to know how to parse the payload data to get a certain value from it using the key.

Example in the following JWT token eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWV9.TJVA95OrM7E2cBab30RMHrHDcEfxjoYZgeFONFh7HgQ

The payload data contains the following object when decoded in jwt.io

{
    "sub" : "1234567890"
    "name" : "John Doe"
    "admin" : "true"
}  

I want to be able to parse this object to get the value of name which in this case is John Doe from …

这是一个例子:

mixin.js

export default {
    methods : {
        aFunction() { // Some functionality here }
    }
}

component.vue

import mixin from './mixin'
export default {
    mixins : [ mixin ]
    created() {
        // Call aFunction defined in the mixin here
    }
}

我想从组件内部的created()生命周期方法访问mixin方法中定义的aFunction.

我正在使用Volley Library在android中发布,我这样做

JsonObjectRequest postRequest = new JsonObjectRequest(URL, new JSONObject(hashMap));

这里是新JsonObjectRequest的第二个参数,我将hashmap转换为JSONObject.

下面是我的hashMap

 Map<String, Object> postparams = new HashMap<String, Object>()
        postparams.put("protocol", "A");
        postparams.put("service_type", "B");
        postparams.put("access_id",accessID);
        postparams.put("contact", contactDetails);

联系人密钥有一个嵌套的JSON作为这样的值

联系方式:{contactName:"ABCD",phoneNumber:"98980980980"}

我该怎么办？

我的尝试:我尝试创建一个hashmap并使用jackson转换它并传递它,但是我得到了一个错误,这是因为我将对象转换为JSON两次.
