java - Google vision API 从文件加载凭证

Question

我想在创建 Annotator 客户端时使用不同的凭据文件。我目前可以像这样使用 transalte API 来做到这一点:

 Credentials creds = ServiceAccountCredentials.fromStream(new FileInputStream("path/to/credentials.json"));
 return TranslateOptions.newBuilder().setCredentials(creds).build().getService();  

ImageAnnotatorClient 是否有等效的方法？

编辑:我正在使用 google cloud java sdk 版本:1.16.0

Answer 1

凭据 🔗 -> CredentialsProvider 🔗

ImageAnnotatorSettings.Builder -> ImageAnnotatorSettings -> ImageAnnotatorClient

示例(主要从文档中复制):

Credentials myCredentials = ServiceAccountCredentials.fromStream(
    new FileInputStream("path/to/credentials.json"));

ImageAnnotatorSettings imageAnnotatorSettings =
    ImageAnnotatorSettings.newBuilder()
    .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
    .build();

ImageAnnotatorClient imageAnnotatorClient =
    ImageAnnotatorClient.create(imageAnnotatorSettings);

• ImageAnnotatorClient:com.google.cloud.vision.v1.ImageAnnotatorClient 🔗
• ImageAnnotatorSettings:com.google.cloud.vision.v1.ImageAnnotatorSettings 🔗
• ClientSettings.Builder:com.google.api.gax.rpc.ClientSettings.Builder 🔗
• FixedCredentialsProvider:com.google.api.gax.core.FixedCredentialsProvider 🔗
• ServiceAccountCredentials:com.google.auth.oauth2.ServiceAccountCredentials 🔗

注意:以上是针对 Java 的。 API for C#是不同的。
