使用google firebase身份驗證對android進行身份驗證

Question

我正在嘗試通過谷歌登錄驗證我的應用程序。

當我嘗試這樣做時，我收到錯誤 Google Sign In failed. Status = Status{statusCode=DEVELOPER_ERROR, resolution=null} Google Sign In failed. Status = Status{statusCode=DEVELOPER_ERROR, resolution=null}

我已生成SHA1密鑰並在FireBase控制台上啟用了Google Auth。

我是Android的身份驗證方面的初學者。

Answer 1

這不起作用的原因是因為未指定ClientID。 這是應該如何做到的：

private static final String googleClientID = "Enter-ClientID-Here";

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(googleClientID)
            .requestEmail()
            .build();

您必須從此處獲取客戶端ID :(轉到FireBase控制台 - >身份驗證 - >登錄方法 - > Google - >點擊Web SDK配置下拉列表 - > Web客戶端ID

PS確保向清單添加以下權限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />

希望這有助於某人。

Answer 2

只需按照以下步驟操作Google SignIn：

1.）在Google Developers Console中創建項目

登錄Google Plus帳戶，然后單擊“創建項目”。 創建谷歌項目

2.）根據您的選擇填寫詳細信息，然后

現在我們需要一個Android應用程序的配置文件。選擇我們剛剛在開發者控制台上創建的應用程序。 並編寫您創建的android studio項目的包名稱。 最后選擇國家，然后單擊繼續。

3.）將此命令命令到Cmd以查找SHA1密鑰。

對於Windows：

keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

對於Linux：

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

復制SHA1並將其粘貼到“啟用Google服務”頁面。

現在點擊啟用Google登錄。 然后單擊繼續以生成配置文件。 現在點擊下載google-services.json獲取配置文件。 現在來到android工作室。

復制json配置文件（您剛剛下載）並將其粘貼到您的google登錄android studio項目（Inside app / directory）中。 喜歡這個配置文件

打開頂級build.gradle文件，並在依賴項中添加以下行。

classpath 'com.google.gms:google-services:1.5.0-beta2'

在build.gradle文件中添加以下依賴項並同步您的google登錄android項目。

compile 'com.google.android.gms:play-services-auth:8.3.0'
    compile 'com.mcxiaoke.volley:library-aar:1.0.0' // this is for fetching the profile image of the user

現在來到activity_main.xml。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">

    <com.google.android.gms.common.SignInButton
        android:id="@+id/sign_in_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal" />

    <com.android.volley.toolbox.NetworkImageView
        android:id="@+id/profileImage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <TextView
        android:text="Name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

    <TextView
        android:id="@+id/textViewName"
        android:textStyle="bold"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />


    <TextView
        android:text="email"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />


    <TextView
        android:id="@+id/textViewEmail"
        android:textStyle="bold"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

現在來MainActivity.java並編寫以下代碼。

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import com.google.android.gms.auth.api.signin.GoogleSignInResult;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.SignInButton;
import com.google.android.gms.common.api.GoogleApiClient;

import org.w3c.dom.Text;

public class MainActivity extends AppCompatActivity implements View.OnClickListener, GoogleApiClient.OnConnectionFailedListener {

    //Signin button
    private SignInButton signInButton;

    //Signing Options
    private GoogleSignInOptions gso;

    //google api client
    private GoogleApiClient mGoogleApiClient;

    //Signin constant to check the activity result
    private int RC_SIGN_IN = 100;

    //TextViews
    private TextView textViewName;
    private TextView textViewEmail;
    private NetworkImageView profilePhoto;

    //Image Loader
    private ImageLoader imageLoader;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //Initializing Views
        textViewName = (TextView) findViewById(R.id.textViewName);
        textViewEmail = (TextView) findViewById(R.id.textViewEmail);
        profilePhoto = (NetworkImageView) findViewById(R.id.profileImage);

        //Initializing google signin option
        gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestEmail()
                .build();

        //Initializing signinbutton
        signInButton = (SignInButton) findViewById(R.id.sign_in_button);
        signInButton.setSize(SignInButton.SIZE_WIDE);
        signInButton.setScopes(gso.getScopeArray());

        //Initializing google api client
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
                .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                .build();


        //Setting onclick listener to signing button
        signInButton.setOnClickListener(this);
    }


    //This function will option signing intent
    private void signIn() {
        //Creating an intent
        Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);

        //Starting intent for result
        startActivityForResult(signInIntent, RC_SIGN_IN);
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        //If signin
        if (requestCode == RC_SIGN_IN) {
            GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
            //Calling a new function to handle signin
            handleSignInResult(result);
        }
    }


    //After the signing we are calling this function
    private void handleSignInResult(GoogleSignInResult result) {
        //If the login succeed
        if (result.isSuccess()) {
            //Getting google account
            GoogleSignInAccount acct = result.getSignInAccount();

            //Displaying name and email
            textViewName.setText(acct.getDisplayName());
            textViewEmail.setText(acct.getEmail());

            //Initializing image loader
            imageLoader = CustomVolleyRequest.getInstance(this.getApplicationContext())
                    .getImageLoader();

            imageLoader.get(acct.getPhotoUrl().toString(),
                    ImageLoader.getImageListener(profilePhoto,
                            R.mipmap.ic_launcher,
                            R.mipmap.ic_launcher));

            //Loading image
            profilePhoto.setImageUrl(acct.getPhotoUrl().toString(), imageLoader);

        } else {
            //If login fails
            Toast.makeText(this, "Login Failed", Toast.LENGTH_LONG).show();
        }
    }

    @Override
    public void onClick(View v) {
        if (v == signInButton) {
            //Calling signin
            signIn();
        }
    }

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {

    }
}

為了從URL加載圖像，我使用了自定義排球請求。對於自定義排球請求，您必須創建以下類。

import android.content.Context;
import android.graphics.Bitmap;
import android.support.v4.util.LruCache;

import com.android.volley.Cache;
import com.android.volley.Network;
import com.android.volley.RequestQueue;
import com.android.volley.toolbox.BasicNetwork;
import com.android.volley.toolbox.DiskBasedCache;
import com.android.volley.toolbox.HurlStack;
import com.android.volley.toolbox.ImageLoader;


public class CustomVolleyRequest {

    private static CustomVolleyRequest customVolleyRequest;
    private static Context context;
    private RequestQueue requestQueue;
    private ImageLoader imageLoader;


    private CustomVolleyRequest(Context context) {
        this.context = context;
        this.requestQueue = getRequestQueue();

        imageLoader = new ImageLoader(requestQueue,
                new ImageLoader.ImageCache() {
                    private final LruCache<String, Bitmap>
                            cache = new LruCache<String, Bitmap>(20);

                    @Override
                    public Bitmap getBitmap(String url) {
                        return cache.get(url);
                    }

                    @Override
                    public void putBitmap(String url, Bitmap bitmap) {
                        cache.put(url, bitmap);
                    }
                });
    }

    public static synchronized CustomVolleyRequest getInstance(Context context) {
        if (customVolleyRequest == null) {
            customVolleyRequest = new CustomVolleyRequest(context);
        }
        return customVolleyRequest;
    }

    public RequestQueue getRequestQueue() {
        if (requestQueue == null) {
            Cache cache = new DiskBasedCache(context.getCacheDir(), 10 * 1024 * 1024);
            Network network = new BasicNetwork(new HurlStack());
            requestQueue = new RequestQueue(cache, network);
            requestQueue.start();
        }
        return requestQueue;
    }

    public ImageLoader getImageLoader() {
        return imageLoader;
    }

現在為您的清單添加互聯網權限並運行您的谷歌登錄Android應用程序。

這就是G-SignIn認證的全部過程！
