Httpclient is not a browser, but a client HTTP transmission class library. Httpclient is used to transmit and receive HTTP messages. Two important classes are used in the httpclient module: httpget and httppost. These two classes are used to submit httpget and httppost requests respectively. Next we will use the above theory as the basis, and then conduct a connection http://www.ip138.com/ips138.aspquery ip practice: First, we need the following jar package: httpclient-4.2.jarhttpclient-cache-4
