Question

我正在尝试编写一个java程序，用于循环文件夹中的图像文件和
在谷歌上进行反向图像搜索（只是尝试在这个问题中使用一个图像）

我找到了一些如下所示的例子，结果会给我一个进行反向图像搜索的网址虽然我想知道如何从结果网站下载其中一张图片。

要添加的一些内容是我已经阅读了新的google api（？）并且我发现它只允许我每天进行100次搜索，因此我选择使用旧版本（？）虽然它警告我方法已弃用。

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;

import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;
import org.apache.http.impl.client.DefaultHttpClient;

public class ReverseImageSearch{
  public static void main(String args[]){
    try {
      HttpClient client = new DefaultHttpClient();
      String url="https://www.google.co.in/searchbyimage/upload";
      String imageFile="C:\\Users\\Chan\\Desktop\\pixiv29706591.jpg";
      HttpPost post = new HttpPost(url);

      MultipartEntity entity = new MultipartEntity();
      entity.addPart("encoded_image", new FileBody(new File(imageFile)));
      entity.addPart("image_url",new StringBody(""));
      entity.addPart("image_content",new StringBody(""));
      entity.addPart("filename",new StringBody(""));
      entity.addPart("h1",new StringBody("en"));
      entity.addPart("bih",new StringBody("179"));
      entity.addPart("biw",new StringBody("1600"));

      post.setEntity(entity);
      HttpResponse response = client.execute(post);
      BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));         

      String line = "";
      while ((line = rd.readLine()) != null) {
        if (line.indexOf("HREF")>0)
            System.out.println(line.substring(8));
           //Problem:
           // get one of the result image from the sites
           // and store it in my PC


      }

    }catch (ClientProtocolException cpx){
      cpx.printStackTrace();
    }catch (IOException ioex){
      ioex.printStackTrace();
    }
 }
}
