Azure AI 内容安全 Java SDK
Azure AI Content Safety Java SDK
使用 Azure AI Content Safety Java SDK 构建内容审核应用程序。
安装
<dependency>
<groupId>com.azure</groupId>
<artifactId>azure-ai-contentsafety</artifactId>
<version>1.1.0-beta.1</version>
</dependency>客户端创建
使用 API 密钥
import com.azure.ai.contentsafety.ContentSafetyClient;
import com.azure.ai.contentsafety.ContentSafetyClientBuilder;
import com.azure.ai.contentsafety.BlocklistClient;
import com.azure.ai.contentsafety.BlocklistClientBuilder;
import com.azure.core.credential.KeyCredential;
String endpoint = System.getenv("CONTENT_SAFETY_ENDPOINT");
String key = System.getenv("CONTENT_SAFETY_KEY");
ContentSafetyClient contentSafetyClient = new ContentSafetyClientBuilder()
.credential(new KeyCredential(key))
.endpoint(endpoint)
.buildClient();
BlocklistClient blocklistClient = new BlocklistClientBuilder()
.credential(new KeyCredential(key))
.endpoint(endpoint)
.buildClient();
使用 DefaultAzureCredential
import com.azure.identity.DefaultAzureCredentialBuilder;
ContentSafetyClient client = new ContentSafetyClientBuilder()
.credential(new DefaultAzureCredentialBuilder().build())
.endpoint(endpoint)
.buildClient();
核心概念
危害类别 (Harm Categories)
| 类别 | 描述 | |----------|-------------| | Hate (仇恨) | 基于身份群体的歧视性语言 | | Sexual (色情) | 性内容、关系、行为 | | Violence (暴力) | 身体伤害、武器、受伤 | | Self-harm (自残) | 自伤、自杀相关内容 |严重程度级别 (Severity Levels)
- 文本:0-7 级(默认输出 0, 2, 4, 6)
- 图像:0, 2, 4, 6(精简量表)
核心模式
分析文本
import com.azure.ai.contentsafety.models.*;
AnalyzeTextResult result = contentSafetyClient.analyzeText(
new AnalyzeTextOptions("This is text to analyze"));
for (TextCategoriesAnalysis category : result.getCategoriesAnalysis()) {
System.out.printf("Category: %s, Severity: %d%n",
category.getCategory(),
category.getSeverity());
}
使用选项分析文本
AnalyzeTextOptions options = new AnalyzeTextOptions("Text to analyze")
.setCategories(Arrays.asList(
TextCategory.HATE,
TextCategory.VIOLENCE))
.setOutputType(AnalyzeTextOutputType.EIGHT_SEVERITY_LEVELS);
AnalyzeTextResult result = contentSafetyClient.analyzeText(options);
使用阻止列表分析文本
AnalyzeTextOptions options = new AnalyzeTextOptions("I h*te you and want to k*ll you")
.setBlocklistNames(Arrays.asList("my-blocklist"))
.setHaltOnBlocklistHit(true);
AnalyzeTextResult result = contentSafetyClient.analyzeText(options);
if (result.getBlocklistsMatch() != null) {
for (TextBlocklistMatch match : result.getBlocklistsMatch()) {
System.out.printf("Blocklist: %s, Item: %s, Text: %s%n",
match.getBlocklistName(),
match.getBlocklistItemId(),
match.getBlocklistItemText());
}
}
分析图像
import com.azure.ai.contentsafety.models.*;
import com.azure.core.util.BinaryData;
import java.nio.file.Files;
import java.nio.file.Paths;
// 从文件读取
byte[] imageBytes = Files.readAllBytes(Paths.get("i
mage.png"));
ContentSafetyImageData imageData = new ContentSafetyImageData()
.setContent(BinaryData.fromBytes(imageBytes));
AnalyzeImageResult result = contentSafetyClient.analyzeImage(
new AnalyzeImageOptions(imageData));
for (ImageCategoriesAnalysis category : result.getCategoriesAnalysis()) {
System.out.printf("Category: %s, Severity: %d%n",
category.getCategory(),
category.getSeverity());
}
通过 URL 分析图像
ContentSafetyImageData imageData = new ContentSafetyImageData()
.setBlobUrl("https://example.com/image.jpg");
AnalyzeImageResult result = contentSafetyClient.analyzeImage(
new AnalyzeImageOptions(imageData));
阻止列表管理
创建或更新阻止列表
import com.azure.core.http.rest.RequestOptions;
import com.azure.core.http.rest.Response;
import com.azure.core.util.BinaryData;
import java.util.Map;
Map<String, String> description = Map.of("description", "Custom blocklist");
BinaryData resource = BinaryData.fromObject(description);
Response<BinaryData> response = blocklistClient.createOrUpdateTextBlocklistWithResponse(
"my-blocklist", resource, new RequestOptions());
if (response.getStatusCode() == 201) {
System.out.println("Blocklist created");
} else if (response.getStatusCode() == 200) {
System.out.println("Blocklist updated");
}
添加阻止项
import com.azure.ai.contentsafety.models.*;
import java.util.Arrays;
List<TextBlocklistItem> items = Arrays.asList(
new TextBlocklistItem("badword1").setDescription("Offensive term"),
new TextBlocklistItem("badword2").setDescription("Another term")
);
AddOrUpdateTextBlocklistItemsResult result = blocklistClient.addOrUpdateBlocklistItems(
"my-blocklist",
new AddOrUpdateTextBlocklistItemsOptions(items));
for (TextBlocklistItem item : result.getBlocklistItems()) {
System.out.printf("Added: %s (ID: %s)%n",
item.getText(),
item.getBlocklistItemId());
}
列出阻止列表
PagedIterable<TextBlocklist> blocklists = blocklistClient.listTextBlocklists();
for (TextBlocklist blocklist : blocklists) {
System.out.printf("Blocklist: %s, Description: %s%n",
blocklist.getName(),
blocklist.getDescription());
}
获取阻止列表
TextBlocklist blocklist = blocklistClient.getTextBlocklist("my-blocklist");
System.out.println("Name: " + blocklist.getName());列出阻止项
PagedIterable<TextBlocklistItem> items =
blocklistClient.listTextBlocklistItems("my-blocklist");
for (TextBlocklistItem item : items) {
System.out.printf("ID: %s, Text: %s%n",
item.getBlocklistItemId(),
item.getText());
}
删除阻止项
List<String> itemIds = Arrays.asList("item-id-1", "item-id-2");
blocklistClient.removeBlocklistItems(
"my-blocklist",
new RemoveTextBlocklistItemsOptions(itemIds));
删除阻止列表
blocklistClient.deleteTextBlocklist("my-blocklist");错误处理
import com.azure.core.exception.HttpResponseException;
try {
contentSafetyClient.analyzeText(new AnalyzeTextOptions("test"));
} catch (HttpResponseException e) {
System.out.println("Status: " + e.getResponse().getStatusCode());
System.out.println("Error: " + e.getMessage());
// 常见错误码:InvalidRequestBody, ResourceNotFound, TooManyRequests
}
环境变量
CONTENT_SAFETY_ENDPOINT=https://<resource>.
cognitiveservices.azure.com/
CONTENT_SAFETY_KEY=<your-api-key>最佳实践
1. 黑名单延迟:更改生效约需 5 分钟
2. 类别选择:仅请求必要的类别以降低延迟
3. 严重程度阈值:严格审核通常拦截严重程度 $\ge 4$ 的内容
4. 批量处理:并行处理多个项目以提高吞吐量
5. 缓存:在适当场景下缓存黑名单结果
