Question

使用带有 java 的 firebase admin sdk 将我的后端服务器连接到 firestore。

这是我进行 firebase 设置的初始化方法

 public void initialize() throws IOException {
        FileInputStream serviceAccount = new FileInputStream(GOOGLE_APPLICATION_CREDENTIALS);
        GoogleCredentials credentials = GoogleCredentials.fromStream(serviceAccount);
        FirebaseOptions options = new FirebaseOptions.Builder()
                .setCredentials(credentials)
                .build();
        FirebaseApp.initializeApp(options);
       
    }

我的项目在运行 Cloud firestore 时工作正常，但是当我尝试通过添加环境变量 FIRESTORE_EMULATOR_HOST运行使用 firestore 本地模拟器时=21=] 我遇到了以下问题

Caused by: com.google.api.gax.rpc.UnauthenticatedException: io.grpc.StatusRuntimeException: UNAUTHENTICATED: Credentials require channel with PRIVACY_AND_INTEGRITY security level.

我也遇到了这个问题...看起来这里修复了一个错误https://github.com/firebase/firebase-admin-java/issues/452

但是...如果您只导入 com.google.firebase:firebase-admin:7.1.0，它似乎使用 google-cloud-firestore:1.35.0，其中没有修复！

您需要指定这两个依赖项才能使其与 build.gradle

中的模拟器一起正常工作

implementation "com.google.firebase:firebase-admin:7.1.0"
implementation "com.google.cloud:google-cloud-firestore:2.1.0"
