introduction:
When doing wireless projects, some part of the communication company's data communication is interactive through XML, so we must dynamically capture data on the fixed Internet provided by the communication company, and study how to capture the data on the fixed URL. Now share it with you.
Class name getPageCode, there is a method getSource, pass the attribute delivery parameters, the parameters are controlled to get the address of the URL, the proxy server settings and output methods, where everyone can expand their own needs, I only provide two The way, one is to write directly to a local file, and the other is to return a string. More details have been made in the class
Thin notes, I think everyone can read it. If I don't understand, I will ask, MSN: Yubo@x263.net.
Call mode:
#REGION test Get a remote web page
GetPagecode GPC = New getPageCode ();
gpc.url = "
http://ppcode.com;
GPC.ProxyState = 1; // Using proxy servers, 0 is not used, set to 1 after 1 after the following proxy settings
gpc.proxyaddress = "
http://proxyname.com; // Proxy server address
gpc.proxyport = "80"; // The port of the proxy server
gpc.proxyaccount = "proxy"; // proxy server account
gpc.proxypassword = "password"; // proxy server password
gpc.proxydomain = "BQC"; // Proxy server domain
GPC.outfilePath = filepath; // Set the place where the output file path is set, if not set, return a string
gpc.getsource (); // Process
String Temperr = gpc.noteMessage; // If an error, here will prompt
String tempcode = gpc.outstring; // Returned string
