I have used the jsoup for java but it retrieves very irrelevant links. Below is my code which I have used so far.
private static Pattern patternDomainName;
private Matcher matcher;
private static final String DOMAIN_NAME_PATTERN
= "([a-zA-Z0-9]([a-zA-Z0-9\\-]{0,61}[a-zA-Z0-9])?\\.)+[a-zA-Z]{2,6}";
static {
patternDomainName = Pattern.compile(DOMAIN_NAME_PATTERN);
}
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
FunnyCrawler obj = new FunnyCrawler();
String str = input.nextLine();
Set<String> result = obj.getDataFromGoogle(str);
for(String temp : result){
System.out.println(temp);
}
System.out.println(result.size());
}
public String getDomainName(String url){
String domainName = "";
matcher = patternDomainName.matcher(url);
if (matcher.find()) {
domainName = matcher.group(0).toLowerCase().trim();
}
return domainName;
}
private Set<String> getDataFromGoogle(String query) {
Set<String> result = new HashSet<String>();
String request = "https://www.google.com/search?q=" + query + "&num=20";
System.out.println("Sending request..." + request);
try {
// need http protocol, set this as a Google bot agent :)
Document doc = Jsoup
.connect(request)
.userAgent(
"Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)")
.timeout(5000).get();
// get all links
Elements links = doc.select("a[href]");
for (Element link : links) {
String temp = link.attr("href");
if(temp.startsWith("/url?q=")){
//use regex to get domain name
result.add(getDomainName(temp));
}
}
} catch (IOException e) {
e.printStackTrace();
}
return result;
}
So, in java is there any other way to get the appropriate google search results which i normally get by using the google.com ? I'm working for jsp servlets so i need to run that code on servlet too....
