从Bing Search api获取所有链接并将其添加到阵列

标签： java xml json bing-api

我有一个问题，因为我是Bing Search API的新手，我不熟悉如何使用它。我想从Bing搜索结果中获取所有链接。所以我在搜索关键字。正在工作，但我希望获得我从我在Java应用程序中包含的Bing Search API获得的结果的链接。问题是我想检索链接并将其保存到数组中。所以我使用XML将其解析为JSON。但是当我试图获取Urls或链接时，我无法得到它们的主要问题。有没有人知道如何做或我做错了？

我希望例如获取http://en.wikipedia.org/wiki/Omonoia（Bing搜索API的搜索结果之一）

以下是一些代码：

String str = "http://maps.google.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true";
URL url = new URL(str);
InputStream is = url.openStream();
int ptr = 0;
StringBuilder builder = new StringBuilder();
while ((ptr = is.read()) != -1) {
builder.append((char) ptr);
}
String xml = builder.toString();

JSONObject jsonObject = XML.toJSONObject(xml);
System.out.println(jsonObject.toString());
System.out.println(jsonObject.get("id"));

一些输出：

我从这个问题中得到了一些源代码：Parsing external XML to JSON in Java?

1 个答案:

答案 0 :(得分：5)

您可以指定格式，因此不必使用XML然后解析为JSON。要获取JSON，只需通知URL中的$format选项，如下所示：

https://api.datamarket.azure.com/Bing/SearchWeb/Web?Query='what      is omonoia'&$format=json

下面是一个检索网址的示例：

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLEncoder;
import java.nio.charset.Charset;
import java.util.Base64;

import org.json.JSONArray;
import org.json.JSONObject;

public class BingSearchApiSample {

    public static void main(final String[] args) throws Exception {
        final String accountKey = "<Your Bing API Key>";
        final String bingUrlPattern = "https://api.datamarket.azure.com/Bing/Search/Web?Query=%%27%s%%27&$format=JSON";

        final String query = URLEncoder.encode("'what      is omonoia'", Charset.defaultCharset().name());
        final String bingUrl = String.format(bingUrlPattern, query);

        final String accountKeyEnc = Base64.getEncoder().encodeToString((accountKey + ":" + accountKey).getBytes());

        final URL url = new URL(bingUrl);
        final URLConnection connection = url.openConnection();
        connection.setRequestProperty("Authorization", "Basic " + accountKeyEnc);

        try (final BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()))) {
            String inputLine;
            final StringBuilder response = new StringBuilder();
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            final JSONObject json = new JSONObject(response.toString());
            final JSONObject d = json.getJSONObject("d");
            final JSONArray results = d.getJSONArray("results");
            final int resultsLength = results.length();
            for (int i = 0; i < resultsLength; i++) {
                final JSONObject aResult = results.getJSONObject(i);
                System.out.println(aResult.get("Url"));
            }
        }
    }

}
