Question

我想在创建Annotator客户端时使用不同的凭证文件。我现在能够使用transalte API这样做：

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

是否有与ImageAnnotatorClient

相同的方法

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

Answer 1

ServiceAccountCredentials - ＆gt; FixedCredentialsProvider - ＆gt; ImageAnnotatorSettings.Builder - ＆gt; ImageAnnotatorSettings - ＆gt; ImageAnnotatorClient

示例（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);

这方面的文档（仍然）令人惊讶地发现和导航令人沮丧。他们之间并不是一贯的联系，有多个版本浮动，网址的变化频率超过应有的水平，而Google的一些链接会返回404.

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

Answer 2

private static ImageAnnotatorSettings  setImageAnnotator() {
    Credentials myCredentials = null;
    try {
        myCredentials = ServiceAccountCredentials.fromStream(
                new FileInputStream("C:\\Users\\Pictures\\Cloudvision\\credentials.json"));
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
        ImageAnnotatorSettings imageAnnotatorSettings = null;
        try {
            imageAnnotatorSettings = ImageAnnotatorSettings.newBuilder()
            .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
            .build();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
