Recently to a public platform to do a weather query function, the principle is to get the data from the interface and then return to the user. The interface used here returns data of the XML type. Then use dom4j parsing.

Originally wanted to use document document = Reader.read ();

Then his argument is a input stream, thinking how to get the GET request to the RESP into a stream, but also on the Internet to check some relevant information, found that the comparison,,, do it yourself ... First from

HttpGet httpget = new HttpGet (_url);            HttpResponse response = Httpclient.execute (HttpGet);                   httpentity entity = response.getentity (); InputStream inputs=entity.getcontent ();

Here to get the return stream of resp, directly to Reader.read (), method, found that the error is coding errors ... A face is crazy, because directly through the browser access is Utf-8 code ah, lying trough what ghost ...

Later using entity.getcontentencoding () The print discovery is that the return stream is gzip encoded ... Ri ...

Use Java's own decompression to solve the pressure is good ....

Gzipinputstream in = new Gzipinputstream (inputs);
