Question

我使用bing api的示例代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;

import org.apache.commons.codec.binary.Base64;
import org.jsoup.Jsoup;
public class bingSearch {
    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        //--------------------------------------Bing search------------------------------
        String searchText = "swim";
        searchText = searchText.replaceAll(" ", "%20");
        String accountKey="Your-AccountKEY";
        byte[] accountKeyBytes = Base64.encodeBase64((accountKey + ":" + accountKey).getBytes());
        String accountKeyEnc = new String(accountKeyBytes);
        URL url;
        try {
            url = new URL(  
                    "https://api.datamarket.azure.com/Data.ashx/Bing/Search/v1/Web?Query=%27" + searchText + "%27&$top=50&$format=Atom");
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setRequestMethod("GET");
        conn.setRequestProperty("Authorization", "Basic " + accountKeyEnc);

     //  conn.setRequestProperty("Accept", "application/json");

        BufferedReader br = new BufferedReader(new InputStreamReader(
                (conn.getInputStream())));
        StringBuilder sb = new StringBuilder();
        String output;
        System.out.println("Output from Server .... \n");
        char[] buffer = new char[4096];
        while ((output = br.readLine()) != null) {
            sb.append(output);

              //  text.append(link + "\n\n\n");//Will print the google search links
            //}     
        } 

        conn.disconnect(); 

        int find = sb.indexOf("<d:Description");

        int total = find + 1000;

        System.out.println("Find index: " + find);
        System.out.println("Total index: " + total);
        sb.getChars(find+35, total, buffer, 0);

        String str = new String(buffer);

        int find2 = str.indexOf("</d:Description>");

        int total2 = find2 + 400;
        System.out.println("Find index: " + find);
        System.out.println("Total index: " + total);
        char[] buffer2 = new char[1024];

        str.getChars(0, find2, buffer2 , 0);
        String str2 = new String(buffer2);
        str2 = Jsoup.parse(str2).text();    
        System.out.println(str2);

        } catch (MalformedURLException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }        
}

输出结果是：

服务器输出....

Find index: 1014
Total index: 2014
Find index: 1014
Total index: 2014

它只显示一个结果，但我需要多个结果。可以使用此代码吗？或者是其他替代此代码？谢谢

在您对Bing的调用中，您要求将结果作为Atom Feed请求，这就是您要回复的内容（该特定查询的长度为38785个字符），您真的应将其视为Atom Feed以更合适的方式解析它。

您只在代码中获得一个结果的原因是您似乎永远不会遍历包含Feed的sb字符串。如果你真的想以这种方式解析feed，你需要在conn.disconnect()之后移动到代码循环并使用类似sb.indexOf("<d:Description", int fromIndex)之类的东西来遍历字符串，每次找到新匹配时都会增加fromIndex。 / p>

但是你真的应该把Bing的响应当作xml-feed来处理它并使用一些xml-library解析它，例如Rome。
