在 C# 中通过自定义图像列表进行审查

项目
08/21/2024

本文中的信息和代码示例可帮助你快速开始使用适用于 .NET 的内容审查器 SDK来执行下列操作：

创建自定义图像列表
添加和从列表中删除图像
获取列表中所有图像的 ID
检索和更新列表元数据
刷新列表搜索索引
针对列表中的图像屏蔽图像
从列表中删除所有图像
删除自定义列表

注意

最多只能使用 5 个图像列表，每个列表中的图像数不得超过 10,000 张。

本指南的控制台应用程序模拟了一些可使用图像列表 API 执行的任务。

如果没有 Azure 订阅，可在开始前创建一个试用帐户。

必须有 API 订阅密钥，才能通过 REST API 或 SDK 使用内容审查器服务。在 Azure 门户中订阅内容审查器服务以获取它。

创建 Visual Studio 项目

向解决方案添加新的“控制台应用(.NET Framework)”项目。

在示例代码中，将项目命名为“ImageLists”。
将此项目选为解决方案的单一启动项目。

安装所需程序包

安装以下 NuGet 包：

Microsoft.Azure.CognitiveServices.ContentModerator
Microsoft.Rest.ClientRuntime
Newtonsoft.Json

更新程序的 using 语句

添加以下 using 语句

using Microsoft.Azure.CognitiveServices.ContentModerator;
using Microsoft.Azure.CognitiveServices.ContentModerator.Models;
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
using System.IO;
using System.Threading;

Create the Content Moderator client

添加以下代码来为订阅创建内容审查器客户端。使用终结点 URL 和订阅密钥的值更新 AzureEndpoint 和 CMSubscriptionKey 字段。可在 Azure 门户中资源的“快速启动”选项卡中找到它们。

/// <summary>
/// Wraps the creation and configuration of a Content Moderator client.
/// </summary>
/// <remarks>This class library contains insecure code. If you adapt this 
/// code for use in production, use a secure method of storing and using
/// your Content Moderator subscription key.</remarks>
public static class Clients
{
	/// <summary>
	/// The base URL for Content Moderator calls.
	/// </summary>
	private static readonly string AzureEndpoint = "YOUR ENDPOINT URL";

	/// <summary>
	/// Your Content Moderator subscription key.
	/// </summary>
	private static readonly string CMSubscriptionKey = "YOUR API KEY";

	/// <summary>
	/// Returns a new Content Moderator client for your subscription.
	/// </summary>
	/// <returns>The new client.</returns>
	/// <remarks>The <see cref="ContentModeratorClient"/> is disposable.
	/// When you have finished using the client,
	/// you should dispose of it either directly or indirectly. </remarks>
	public static ContentModeratorClient NewClient()
	{
		// Create and initialize an instance of the Content Moderator API wrapper.
		ContentModeratorClient client = new ContentModeratorClient(new ApiKeyServiceClientCredentials(CMSubscriptionKey));

		client.Endpoint = AzureEndpoint;
		return client;
	}
}

重要

完成后，请记住将密钥从代码中删除，并且永远不要公开发布该密钥。对于生产来说，请使用安全的方式存储和访问凭据，例如 Azure Key Vault。有关详细信息，请参阅 Azure AI 服务安全性一文。

初始化应用专用设置

向 Program.cs 中的 Program 类添加以下类和静态字段。

注意

内容审查器服务密钥有每秒请求数 (RPS) 速率限制。如果超出此限制，SDK 就会抛出异常（错误代码为 429）。免费层密钥有一个单 RPS 速率限制。

创建用于将消息写入日志文件的方法

将以下方法添加到 Program 类。

/// <summary>
/// Writes a message to the log file, and optionally to the console.
/// </summary>
/// <param name="message">The message.</param>
/// <param name="echo">if set to <c>true</c>, write the message to the console.</param>

{
	// Create the request body.
	listDetails = new Body("MyList", "A sample list",
		new BodyMetadata("Acceptable", "Potentially racy"));

	WriteLine($"Creating list {listDetails.Name}.", true);

	var result = client.ListManagementImageLists.Create(

private static void AddImages(
ContentModeratorClient client, int listId,
IEnumerable<string> imagesToAdd, string label)
{

			ImageIdMap.Add(imageUrl, Int32.Parse(result.ContentId));

			WriteLine("Response:");

		}
		finally
		{
			Thread.Sleep(throttleRate);
		}
	}
}

创建一个方法来从列表中删除图像

/// <param name="listId">The list identifier.</param>
private static void DeleteAllImages(
	ContentModeratorClient client, int listId)
{
	WriteLine();
	WriteLine($"Deleting all images from list {listId}.", true);

	var result = client.ListManagementImage.DeleteAllImages(listId.ToString());
	Thread.Sleep(throttleRate);

	WriteLine("Response:");
	WriteLine(JsonConvert.SerializeObject(result, Formatting.Indented));
}

/// <summary>
/// Gets all list identifiers for the client.
/// </summary>
/// <param name="client">The Content Moderator client.</param>
/// <returns>The response object from the operation.</returns>
private static IList<ImageList> GetAllListIds(ContentModeratorClient client)
{
	WriteLine();
	WriteLine($"Getting all image list IDs.", true);

	var result = client.ListManagementImageLists.GetAllImageLists();
	Thread.Sleep(throttleRate);

	WriteLine("Response:");
	WriteLine(JsonConvert.SerializeObject(result, Formatting.Indented));

	return result;
}

添加代码以模拟使用图像列表

将以下代码添加到 Main 方法。此代码将模拟在定义和管理列表以及使用列表来屏蔽图像时执行的诸多操作。借助日志记录功能，可以查看通过对内容审查器服务执行 SDK 调用生成的响应对象。

// Create the text writer to use for logging, and cache a static reference to it.
using (StreamWriter outputWriter = new StreamWriter(OutputFile))
{
	writer = outputWriter;

	// Create a Content Moderator client.
	using (var client = Clients.NewClient())
	{
		// Create a custom image list and record the ID assigned to it.
		var creationResult = CreateCustomList(client);
		if (creationResult.Id.HasValue)
		{
			// Cache the ID of the new image list.
			int listId = creationResult.Id.Value;

			// Perform various operations using the image list.
			AddImages(client, listId, Images.Sports.Urls, Images.Sports.Label);
			AddImages(client, listId, Images.Swimsuit.Urls, Images.Swimsuit.Label);
					
			GetAllImageIds(client, listId);
			UpdateListDetails(client, listId);
			GetListDetails(client, listId);

			// Be sure to refresh search index
			RefreshSearchIndex(client, listId);

			// WriteLine();
			WriteLine($"Waiting {latencyDelay} minutes to allow the server time to propagate the index changes.", true);
			Thread.Sleep((int)(latencyDelay * 60 * 1000));

			// Match images against the image list.
			MatchImages(client, listId, ImagesToMatch);

			// Remove images
			RemoveImages(client, listId, Images.Corrections);

			// Be sure to refresh search index
			RefreshSearchIndex(client, listId);

			WriteLine();
			WriteLine($"Waiting {latencyDelay} minutes to allow the server time to propagate the index changes.", true);
			Thread.Sleep((int)(latencyDelay * 60 * 1000));

			// Match images again against the image list. The removed image should not get matched.
			MatchImages(client, listId, ImagesToMatch);

			// Delete all images from the list.
			DeleteAllImages(client, listId);

			// Delete the image list.
			DeleteCustomList(client, listId);

			// Verify that the list was deleted.
			GetAllListIds(client);
			}
		}

		writer.Flush();
		writer.Close();
		writer = null;
}

Console.WriteLine();
Console.WriteLine("Press any key to exit...");
Console.ReadKey();

运行程序并查看输出

列表 ID 和图像内容 ID 在每次运行应用程序时都是不同的。由程序写入的日志文件具有以下输出：
