本文介绍了如何在iOS应用中使用NSMutableURLRequest进行网络请求，并通过JSON格式传递数据。包括了同步请求的实现方式及服务器端处理请求的方法。

NSMutableURLRequest *request=[[NSMutableURLRequestalloc]init];

  NSUserDefaults *defs =[NSUserDefaultsstandardUserDefaults];
   NSLog(@"LoadcurrentCookie:%@", cookie);
   [requestsetValue:cookieforHTTPHeaderField:@"Cookie"];
   [requestsetURL:[aobjectAtIndex:0]];
   [requestsetHTTPMethod:@"GET"];
   NSData *returnData =[NSURLConnectionsendSynchronousRequest:request
                                              returningResponse:nilerror:nil];
   [requestrelease];

一、iPhone终端代码：
（同步请求）
NSString *post = nil;
post = [[NSString alloc]initWithFormat:@"message=%@",@"hello,world."];
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncodingallowLossyConversion:YES];
NSString *postLength = [NSString stringWithFormat:@"%d", [postDatalength]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init]autorelease];
[request setURL:[NSURLURLWithString:@"http://192.168.10.220:18080/data/1.jsp"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLengthforHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded"forHTTPHeaderField:@"Content-Type"];
[requestsetHTTPBody:postData];
//[NSURLConnection connectionWithRequest:request delegate:self];

//同步请求的的代码
//returnData就是返回得到的数据
NSData *returnData = [NSURLConnectionsendSynchronousRequest:request returningRequest:nilerror:nil];

[post release];

二、web服务器端代码
<%
String message = request.getParameter("message");
System.out.println("message="+message);
out.println("message="+message);
%>

采用json 格式post 字符串

static NSString *urlString =@"http://192.168.1.103/WebAccess/admin/tablesSync.aspx";
//static NSString *urlString = @"http://www.google.cn";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:urlString]];
NSString *httpBodyString = @"a test string";

NSMutableArray *arrayData = [[NSMutableArray alloc] init]；

NSMutableDictionary *dlist = [[NSMutableDictionary alloc]init];
[dlist setObject:@"tblArea" forKey:@"tableName"];
[dlist setObject:@"2009-10-24 11:20:00"forKey:@"lastChangeDate"];
[arrayData addObject:dlist];

//[request setHTTPBody:[httpBodyStringdataUsingEncoding:NSUTF8StringEncoding]];
//
   //post = [[NSString alloc]initWithFormat:@"message=%@",@"hello,world."];
httpBodyString = [arrayDataJSONRepresentation];
NSData *postData = [httpBodyStringdataUsingEncoding:NSASCIIStringEncodingallowLossyConversion:YES];
[request setHTTPBody:postData];
[request setHTTPMethod:@"POST"];
//
NSURLResponse *reponse;
NSError *error = nil;
//
NSData *responseData = [NSURLConnectionsendSynchronousRequest:requestreturningResponse:&reponseerror:&error];
if (error) {
NSLog(@"Something wrong: %@",[errordescription]);
}else {
if (responseData) {
   NSString *responseString =[[NSString alloc] initWithData:responseDataencoding:NSUTF8StringEncoding];
   NSLog(@"get%@",responseString);
}
}

NSMutableDictionary *dgetData = [responseString JSONValue];
NSLog(@"dgetData: %@" , [dgetData description]);

[dlist release];
[arrayData release];
