Question

我已成功在Android应用中实现了具有Firebase身份验证的 google登录。

如您所见，我已经用我的帐户登录，它显示在Firebase控制台上。

firebaseAuthWithGoogle 函数在用户使用Google登录名登录后使用Firebase对用户进行身份验证：

private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
    Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mFirebaseAuth.signInWithCredential(credential)
        .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
            @Override
            public void onComplete(@NonNull Task<AuthResult> task) {
                if (task.isSuccessful()) {
                    // Sign in success, update UI with the signed-in user's information
                    Log.d(TAG, "signInWithCredential:success");
                    final FirebaseUser user = mFirebaseAuth.getCurrentUser();


                    //This is to connect to the http server and save the user data in my MySql database
                    FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(LoginActivity.this, new OnSuccessListener<InstanceIdResult>() {
                        @Override
                        public void onSuccess(InstanceIdResult instanceIdResult) {
                            String userToken = instanceIdResult.getToken();
                            String uid = user.getUid();
                            String name = user.getDisplayName();
                            String email = user.getEmail();
                            String profileUrl = user.getPhotoUrl().toString();
                            String coverUrl = "";
                            UserInterface userInterface = ApiClient.getApiClient().create(UserInterface.class);
                            Call<Integer> call = userInterface.signin(new LoginActivity.UserInfo(uid,name,email,profileUrl,coverUrl,userToken));

                            call.enqueue(new Callback<Integer>() {
                                @Override
                                public void onResponse(Call<Integer> call, Response<Integer> response) {
                                    progressDialog.dismiss();
                                    Toast.makeText(LoginActivity.this,"Login succesfull AFTER API CALL",Toast.LENGTH_SHORT).show();
                                    startActivity(new Intent(LoginActivity.this,MainActivity.class));
                                    finish();

                                }

                                @Override
                                public void onFailure(Call<Integer> call, Throwable t) {
                                    progressDialog.dismiss();
                                    Toast.makeText(LoginActivity.this,"Login failed AFTER API CALL",Toast.LENGTH_SHORT).show();

                                }
                            });
                        }
                    });
                } else {
                    // If sign in fails, display a message to the user.


                 Log.w(TAG, "signInWithCredential:failure", task.getException());
                    }

                    // ...
                }
            });
}

功能 firebaseAuthWithGoogle 的另一件事是：连接到http Apache服务器并将用户信息保存在 MySQL用户表中> ，通过以下代码段：

 //This is to connect to the http server and save the user data in my MySql database
                        FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(LoginActivity.this, new OnSuccessListener<InstanceIdResult>() {
                            @Override
                            public void onSuccess(InstanceIdResult instanceIdResult) {
                                String userToken = instanceIdResult.getToken();
                                String uid = user.getUid();
                                String name = user.getDisplayName();
                                String email = user.getEmail();
                                String profileUrl = user.getPhotoUrl().toString();
                                String coverUrl = "";
                                UserInterface userInterface = ApiClient.getApiClient().create(UserInterface.class);
                                Call<Integer> call = userInterface.signin(new LoginActivity.UserInfo(uid,name,email,profileUrl,coverUrl,userToken));

                                call.enqueue(new Callback<Integer>() {
                                    @Override
                                    public void onResponse(Call<Integer> call, Response<Integer> response) {
                                        progressDialog.dismiss();
                                        Toast.makeText(LoginActivity.this,"Login succesfull AFTER API CALL",Toast.LENGTH_SHORT).show();
                                        startActivity(new Intent(LoginActivity.this,MainActivity.class));
                                        finish();

                                    }

                                    @Override
                                    public void onFailure(Call<Integer> call, Throwable t) {
                                        progressDialog.dismiss();
                                        Toast.makeText(LoginActivity.this,"Login failed AFTER API CALL",Toast.LENGTH_SHORT).show();

                                    }
                                });
                            }
                        });
                    }

因此，在用户成功通过身份验证之后，对服务器的调用将失败，并且显然将执行以下行：

 Toast.makeText(LoginActivity.this,"Login failed AFTER API CALL",Toast.LENGTH_SHORT).show();

我将 Retrofit 用作 http客户端，并将 okhttp 用作 http正文拦截器 ，以 记录http请求 ，如下所示：

ApiClient.java

  public  static  Retrofit getApiClient(){
        HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor().setLevel(HttpLoggingInterceptor.Level.BODY);
        OkHttpClient httpClient = new OkHttpClient.Builder()
                .addInterceptor(httpLoggingInterceptor)
                .build();

        if(retrofit==null){
            retrofit = new Retrofit.Builder().baseUrl(BASE_URL)
                    .client(httpClient)
                    .addConverterFactory(GsonConverterFactory.create())
                    .build();

        }
        return retrofit;
    }
}

因此，在Toast Text “ API API CALL之后登录失败” 出现在模拟器上之后，我将其记录在日志上：

D/OkHttp: --> POST http://10.0.2.2/friendster/public/app/login

D/OkHttp: <-- HTTP FAILED: java.net.UnknownServiceException: CLEARTEXT communication to 10.0.2.2 not permitted by network security policy

所以我发现这是导致错误的原因：

与网络安全不允许的CLEARTEXT与10.0.2.2的通信政策

经过StackOverflow之后，我发现需要创建此文件：

src / main / res / xml / network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">api.example.com(to be adjusted)</domain>
    </domain-config>
</network-security-config>

并将其添加到清单中：

 <application
     ---
        android:networkSecurityConfig="@xml/network_security_config">

已经用Postman测试了我的数据库，我确定问题出在我的Android项目中。
我认为这应该已经解决了问题。但是，我仍然有完全相同的问题。我仍然在日志中收到此错误：

与网络安全不允许的CLEARTEXT与10.0.2.2的通信政策

Answer 1

将其替换为安全配置文件：

src / main / res / xml / network_security_config.xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <!--Set application-wide security config using base-config tag.-->
    <base-config cleartextTrafficPermitted="true"/>
</network-security-config>

它解决了我的问题：）

Answer 2

在 AndroidManifest.xml 中，只需使用这一行。它解决了我的问题。

<application
    ...
    android:usesCleartextTraffic="true">
</application>

Answer 3

OkHttp：<— HTTP 失败：java.net.UnknownServiceException：网络安全策略不允许与 10.0.2.2 的 CLEARTEXT 通信

如果你不显示 api 显示图像而不是 android:usesCleartextTraffic="true"

OkHttp：<-HTTP失败：java.net.UnknownServiceException：网络安全策略不允许与10.0.2.2的CLEARTEXT通信
