Yur*_*uri 6 java google-cloud-platform gcloud-java dialogflow-es
嗨,我遇到了Google Cloud的Java SDK库问题。
我需要查询Dialogflow V2 API,并且正在使用此SDK(https://github.com/GoogleCloudPlatform/google-cloud-java/tree/master)
我已按照说明进行操作,以将GOOGLE_APPLICATION_CREDENTIALS设置为环境变量。
我做了几次尝试(我使用的是Mac):
export GOOGLE_APPLICATION_CREDENTIALS=path/to/my.json
Run Code Online (Sandbox Code Playgroud)
不起作用
推杆
export GOOGLE_APPLICATION_CREDENTIALS=path/to/my.json
Run Code Online (Sandbox Code Playgroud)
在.bash_profile中
不起作用
在我的Java代码中:
System.setProperty("GOOGLE_APPLICATION_CREDENTIALS", "/path/to/my.json");
GoogleCredential credential = GoogleCredential.getApplicationDefault();
Run Code Online (Sandbox Code Playgroud)
不起作用
String jsonPath = "/path/to/my.json";
GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream(jsonPath));
Storage storage = StorageOptions.newBuilder().setCredentials(credentials).build().getService();

不起作用
通过“ Maven构建>环境>新变量”将GOOGLE_APPLICATION_CREDENTIALS作为Eclipse中的环境变量,然后重新启动IDE
不起作用
总是发生相同的错误:
An error occurred during Dialogflow http request: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.
java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information

真的我无法理解错在哪里。
这是由于上述错误而无法查询Dialogflow的代码片段:
SessionsClient sessionsClient = SessionsClient.create();
SessionName session = SessionName.of("my-project-id", sessionId);
InputStream stream = new ByteArrayInputStream(requestBody.getBytes(StandardCharsets.UTF_8));
QueryInput queryInput = QueryInput.newBuilder().build().parseFrom(stream);
DetectIntentResponse response = sessionsClient.detectIntent(session, queryInput);

发生例外
SessionsClient sessionsClient = SessionsClient.create();

提前致谢。

与问题中提到的不同,以这种方式提供时我已经获得了有效的“凭据”
Storage storage = StorageOptions.newBuilder().setCredentials(credentials).build().getService();

但同样的方法FirestoreOptions失败并出现上述错误“应用程序默认凭据不可用”。
注意:我愿意不通过环境变量配置我的应用程序,而更喜欢在代码中进行配置。还有一个原因 - 我需要来自一个应用程序的多个不同连接。
在调试 Google 的代码后,我发现他们不使用提供的凭据,而是调用getCredentialsProvider()提供的选项。我认为这是他们实现中的错误,但解决方法相当简单:
虚拟样本:
public static class MyCredentialsProvider implements CredentialsProvider {
GoogleCredentials credentials;
public MyCredentialsProvider(GoogleCredentials credentials) {
this.credentials = credentials;
}
@Override
public Credentials getCredentials() throws IOException {
return credentials;
}
}
...
FirestoreOptions.Builder builder = FirestoreOptions.newBuilder()
.setProjectId(serviceAccount.project_id)
.setCredentialsProvider(new MyCredentialsProvider(credentials));
