如何在bing搜索中访问搜索结果的数量? 我发现这个帖子: How to get number of search result from Bing API
在这个帖子中,我明白我应该使用d->results[0]->WebTotal
但我如何在java中使用这一行?
public static void main(String[] args) throws Exception {
//term1
String searchText = "is";
searchText = searchText.replaceAll(" ", "%20");
String accountKey="WOCKN8uXArczOkQq5phtoEc7usB0kDoPTnbqn0sKWeg";
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);
} catch (MalformedURLException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

答案 0 :(得分:1)
我找到了答案:
public static void main(String[] args) {
String searchText = "searchtext";
searchText = searchText.replaceAll(" ", "%20");
String accountKey="key_ID";
byte[] accountKeyBytes = Base64.encodeBase64((accountKey + ":" + accountKey).getBytes());
String accountKeyEnc = new String(accountKeyBytes);
URL url;
try {
url = new URL(
"https://api.datamarket.azure.com/Bing/Search/v1/Composite?Sources=%27Web%27&Query=%27" + searchText + "%27&$format=JSON");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
conn.setRequestProperty("Authorization", "Basic " + accountKeyEnc);
BufferedReader br = new BufferedReader(new InputStreamReader(
(conn.getInputStream())));
StringBuilder sb = new StringBuilder();
String output;
System.out.println("Output from Server .... \n");
//write json to string sb
while ((output = br.readLine()) != null) {
sb.append(output);
}
conn.disconnect();
//find webtotal among output
int find= sb.indexOf("\"WebTotal\":\"");
int startindex = find + 12;
int lastindex = sb.indexOf("\",\"WebOffset\"");
System.out.println(sb.substring(startindex,lastindex));
} catch (MalformedURLException e1) {
e1.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
