I'm trying to get the "Title" from a webpage using Apache HttpClient 4.
Edit: My first approach was trying to get it from the header (using HttpHead). If that is not possible, how can I get it from the body of the response, as @Todd says?
Edit 2:
<head>
[...]
<title>This is what I need to get!</title>
[...]
</head>
Thank you everyone for your comments. The solution was pretty simple once jsoup was used.
Document doc = Jsoup.connect("http://example.com/").get();
String title = doc.title();
Considering that I really need to connect using HttpClient, this is what I have:
org.jsoup.nodes.Document doc = null;
String title = "";
System.out.println("Getting content... ");
CloseableHttpClient httpclient = HttpClients.createDefault();
HttpHost target = new HttpHost(host);
HttpGet httpget = new HttpGet(path);
CloseableHttpResponse response = httpclient.execute(target, httpget);
System.out.println("Parsing content... ");
try {
String line = null;
StringBuffer tmp = new StringBuffer();
BufferedReader in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
while ((line = in.readLine()) != null) {
String decoded = new String(line.getBytes(), "UTF-8");
tmp.append(" ").append(decoded);
}
doc = Jsoup.parse(String.valueOf(tmp));
title = doc.title();
System.out.println("Title=" + title); //<== ^_^
//[...]
} finally {
response.close();
}
System.out.println("Done.");
