如何在请求中添加safesearch？

在请求中添加SafeSearch参数，主要是指在使用Google Cloud Vision API进行图像内容审核时，通过设置SafeSearch参数来控制返回的图片内容是否包含色情、暴力等敏感信息。以下是在不同编程语言中如何添加SafeSearch参数的示例。

Python

使用Google Cloud Vision API的Python客户端库时，可以通过设置safe_search_detection_config参数来添加SafeSearch功能。

from google.cloud import vision
from google.cloud.vision_v1 import types

client = vision.ImageAnnotatorClient()

image = types.Image(content=b'your_image_content')

features = [
    types.Feature(type_=vision.enums.Feature.Type.SAFE_SEARCH_DETECTION),
]

request = types.AnnotateImageRequest(
    image=image,
    features=features,
    image_context=types.ImageContext(safe_search_detection_config=types.SafeSearchDetectionConfig(level='HIGH'))
)

response = client.annotate_image(request)
safe_search_result = response.safe_search_annotation

print(safe_search_result.label_annotations)

Java

在Java中，可以通过设置ImageContext的safeSearchDetectionConfig属性来添加SafeSearch功能。

import com.google.cloud.vision.v1.*;
import com.google.protobuf.ByteString;

public class SafeSearchExample {
    public static void main(String[] args) throws Exception {
        ImageAnnotatorClient vision = ImageAnnotatorClient.create();

        ByteString imgBytes = ByteString.readFrom(new FileInputStream("path/to/your/image.jpg"));
        Image img = Image.newBuilder().setContent(imgBytes).build();

        Feature feat = Feature.newBuilder().setType(Feature.Type.SAFE_SEARCH_DETECTION).build();
        AnnotateImageRequest request = AnnotateImageRequest.newBuilder()
                .addFeatures(feat)
                .setImage(img)
                .setImageContext(ImageContext.newBuilder()
                        .setSafeSearchDetectionConfig(SafeSearchDetectionConfig.newBuilder().setLevel(SafeSearchDetectionConfig.Level.HIGH).build())
                        .build())
                .build();

        BatchAnnotateImagesResponse response = vision.batchAnnotateImages(Arrays.asList(request));
        List<AnnotateImageResponse> responses = response.getResponsesList();

        for (AnnotateImageResponse res : responses) {
            if (res.hasError()) {
                System.out.format("Error: %s%n", res.getError().getMessage());
                return;
            }
            SafeSearchAnnotation annotation = res.getSafeSearchAnnotation();
            System.out.println(annotation.getLabelAnnotationsList());
        }

        vision.close();
    }
}

Node.js

在Node.js中，可以通过设置imageContext的safeSearchDetectionConfig属性来添加SafeSearch功能。

const { ImageAnnotatorClient } = require('@google-cloud/vision');

async function detectSafeSearch() {
  const client = new ImageAnnotatorClient();

  const [result] = await client
    .safeSearchDetection('path/to/your/image.jpg')
    .then(responses => {
      const annotation = responses[0].safeSearchAnnotation;
      console.log(annotation);
    })
    .catch(err => {
      console.error('ERROR:', err);
    });

  client.close();
}

detectSafeSearch();

在上述示例中，SAFE_SEARCH_DETECTION_CONFIG的level参数可以设置为以下值之一：
