Sending HTTP requests for IOS4.2 Network Learning

IOS4.2Sending of Network LearningHTTP RequestYes. What I want to introduce in this article is mainly about sendingHTTP RequestLet me learn about the IOS-related network content. Let's take a look at the details first.

Development Environment client: mac OS x 10.6.6, ios 4.2 + xcode3.2.5 server: windows xp + iis + asp.net

The Code is as follows:

 
 

  
  
-(IBAction) sendHttp: (id) sender {
  
  

  
  
// Send an http request through GET
  
  
// NSUTF8StringEncoding encoding is required for any Chinese Characters
  
  
 
  
  
NSString * urlString = [[NSString stringWithFormat: @ "http: // 127.0.0.1/default. aspx? Uc = % @ ", @" test"
  
  
StringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
  
  
 
  
  
// Initialize the http request and release the memory automatically
  
  
 
  
  
NSMutableURLRequest * request = [[NSMutableURLRequest alloc] init] autorelease];
  
  
 
  
  
[Request setURL: [NSURL URLWithString: urlString];
  
  
[Request setHTTPMethod: @ "GET"];
  
  
 
  
  
NSString * contentType = [NSString stringWithFormat: @ "text/xml"];
  
  
[Request addValue: contentType forHTTPHeaderField: @ "Content-Type"];
  
  
 
  
  
NSHTTPURLResponse * urlResponse = nil;
  
  
NSError * error = [[NSError alloc] init];
  
  
 
  
  
// Synchronously return the request and obtain the returned data
  
  
 
  
  
NSData * responseData = [NSURLConnection sendSynchronousRequest: request returningResponse: & urlResponse error: & error];
  
  
NSString * result = [[NSString alloc] initWithData: responseData encoding: NSUTF8StringEncoding];
  
  
// The return status of the request. If the request cannot be sent in Chinese, the value of stausCode is 0.
  
  
NSLog (@ "response code: % d", [urlResponse statusCode]);
  
  
If ([urlResponse statusCode]> = 200 & [urlResponse statusCode] <300 ){
  
  
NSLog (@ "response: % @", result );
  
  
Messag. text = [NSString stringWithFormat: @ "% @", result];
  
  
}
  
  
}
 
 

Server:

The content of the default. aspx file is as follows (clear the automatically generated file and only save the following content)

 
 

  
  
<%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %> 
 
 

Default. aspx. cs File

Add the following code in Page_Load mode:

 
 

  
  
if (Request.Params["uc"] != null )  
  
  
{  
  
  
    string userAcount  = Request.Params["uc"];  
  
  
    Response.Write("success" + userAcount );  
  
  
}  
  
  
else  
  
  
{  
  
  
    Response.Write("fail");  
  
  
} 
 
 

OK. After the code has been compiled, publish the iis Site for testing.
