[英]GCP DialogFlow API error: "The Application Default Credentials are not available"
[英]Google Dialogflow: The Application Default Credentials are not available
嗨,我對 Google Cloud 的 Java SDK 庫有疑問。
我需要查詢 Dialogflow V2 API,我正在使用這個 SDK ( https://github.com/GoogleCloudPlatform/google-cloud-java/tree/master )
我已按照說明將 GOOGLE_APPLICATION_CREDENTIALS 設置為環境變量。
我做了幾次嘗試(我使用的是 Mac):
export GOOGLE_APPLICATION_CREDENTIALS=path/to/my.json
不工作
推桿
export GOOGLE_APPLICATION_CREDENTIALS=path/to/my.json
在 .bash_profile
不工作
在我的 Java 代碼中:
System.setProperty("GOOGLE_APPLICATION_CREDENTIALS", "/path/to/my.json");
GoogleCredential credential = GoogleCredential.getApplicationDefault();
不工作
String jsonPath = "/path/to/my.json";
GoogleCredentials credentials = GoogleCredentials.fromStream(new FileInputStream(jsonPath));
Storage storage = StorageOptions.newBuilder().setCredentials(credentials).build().getService();
不工作
通過“Maven build > Environment > New variable”將 GOOGLE_APPLICATION_CREDENTIALS 作為 Eclipse 中的環境變量並重新啟動 IDE
不工作
總是出現同樣的錯誤:
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
真的我無法理解出了什么問題。
由於上述錯誤,這是查詢 Dialogflow 從未到達的代碼片段:
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);
引發異常
SessionsClient sessionsClient = SessionsClient.create();
提前致謝。
解決方案是將 GOOGLE_APPLICATION_CREDENTIALS 設置為 Application Server 的環境變量。
與問題中提到的不同,以這種方式提供時,我已經獲得了“憑證”
Storage storage = StorageOptions.newBuilder().setCredentials(credentials).build().getService();
但是與FirestoreOptions
相同的方法失敗了,並提到了錯誤“應用程序默認憑據不可用”。
注意:我願意不通過環境變量配置我的應用程序,而是更喜歡在代碼中進行配置。 另一個原因 - 我需要來自一個應用程序的多個不同連接。
在調試 Google 的代碼后,我發現他們不使用提供的憑據,而是在提供的選項上調用getCredentialsProvider()
。 我認為這是他們實現中的錯誤,但解決方法相當簡單:
虛擬樣本:
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));
