Android Learning (49)--submit data using GET method

The data submitted by the Get method is directly stitched at the end of the URL

Final String Path = "Http://192.168.1.103/Web/servlet/CheckLogin?name=" + name + "&pass=" + Pass;

Send a GET request, the code is the same as before

URL url = new URL (path); HttpURLConnection conn = (httpurlconnection) url.openconnection (); Conn.setrequestmethod ("GET"); conn.setreadtimeout (conn.setconnecttimeout); if (conn.getresponsecode () = = 200) {}

When the browser sends the request carries the data the data URL encodes, we also need to write the code in the Chinese URL encoding urlencoder.encode (name), is outdated, the code is UTF-8, this is more convenient,
Urlencoder.encode (name, "Utf-8"), this is not obsolete, if the encoding is not utf-8 need to use this.

String Path = "Http://192.168.1.103/Web/servlet/CheckLogin?name=" + urlencoder.encode (name) + "&pass=" + Pass;
