您好,我有一个关于 Google Cloud 的 Java SDK 库的问题。
我需要查询 Dialogflow V2 API,我正在使用这个 SDK ( https://github.com/GoogleCloudPlatform/google-cloud-java/tree/master )
我已按照说明将 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
不起作用
放
export GOOGLE_APPLICATION_CREDENTIALS=path/to/my.json
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();
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 build > Environment > New variable”将 GOOGLE_APPLICATION_CREDENTIALS 作为环境变量放入 Eclipse 并重启 IDE
不起作用
总是出现同样的错误:
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
真的我不明白哪里出了问题。
这是用于查询由于上述错误而从未到达的 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);
异常发生在
SessionsClient sessionsClient = SessionsClient.create();
提前致谢。
最佳答案
解决方案是将 GOOGLE_APPLICATION_CREDENTIALS 设置为应用服务器的环境变量。
