java - Java 创建人员组的 Microsoft 认知服务 Face API 错误

Question

此代码用于使用 Java 创建人员组。

import java.net.URI;
import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.utils.URIBuilder;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.util.EntityUtils;

public class JavaSample 
{
    public static void main(String[] args) 
    {
        HttpClient httpclient = HttpClients.createDefault();

        try
        {
            URIBuilder builder = new URIBuilder("https://api.projectoxford.ai/face/v1.0/persongroups/personGroupId");


            URI uri = builder.build();
            HttpPut request = new HttpPut(uri);
            request.setHeader("Content-Type", "application/json");
            request.setHeader("Ocp-Apim-Subscription-Key", "mysubscriptionkey");


            // Request body
            StringEntity reqEntity = new StringEntity("{body}");
            request.setEntity(reqEntity);

            HttpResponse response = httpclient.execute(request);
            HttpEntity entity = response.getEntity();

            if (entity != null) 
            {
                System.out.println(EntityUtils.toString(entity));
            }
        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}

当我运行此代码时，出现以下错误:

{"error":{"code":"BadArgument","message":"Request body is invalid."}}

我能做些什么来修复它。我在互联网上没有找到使用java创建人员组的示例，所以我无法修复它。

Answer 1

正如错误所示，HTTP 请求正文的格式错误为 {body}。

请查看 API页面上标记为请求正文的部分下。您需要提供名称，并且可以选择添加用户数据。

StringEntity reqEntity = new StringEntity("{" +
    "\"name\":\"group1\"," +
    "\"userData\":\"user-provided data attached to the person group\""+
"}") 

您可以在 GitHub SDK 上找到一些其他 Java 示例页。
