Google视觉API从文件加载凭据

Question

创建注释器客户端时，我想使用其他凭证文件。我目前可以使用transalte API做到这一点，如下所示：

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

是否有使用的等效方法ImageAnnotatorClient？

编辑：我正在使用谷歌云的Java SDK版本：1.16.0

Answer 1

ServiceAccountCredentials-> FixedCredentialsProvider-> ImageAnnotatorSettings.Builder-> ImageAnnotatorSettings->ImageAnnotatorClient

示例（从文档复制）：

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

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

ImageAnnotatorClient imageAnnotatorClient =
    ImageAnnotatorClient.create(imageAnnotatorSettings);

用于此的文档（仍然）令人惊讶地令人沮丧，无法找到和导航。它们之间无法始终保持链接，周围有多个版本，URL更改的频率比他们应有的频繁，并且许多Google自己的链接返回404。
