【问题标题】:Microsoft Cognitive Services Face API Error for Java Create a Person Group适用于 Java 的 Microsoft 认知服务人脸 API 错误创建人员组
【发布时间】:2017-01-17 02:44:40
【问题描述】:

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());
        }
    }
}

当我运行这段代码时,我得到了这个错误:

{"error":{"code":"BadArgument","message":"请求正文无效。"}}

我能做些什么来修复它。我在网上没有找到用java创建人组的示例,所以无法修复。

    【解决方案1】:

    正如错误提示,HTTP 请求正文格式错误为{body}

    请查看API 页面,在标有请求正文的部分下。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 页面上找到一些其他 Java 示例。
