    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];NSUserDefaults *defs = [NSUserDefaults standardUserDefaults];NSLog(@"Load currentCookie:%@", cookie);[request setValue:cookie forHTTPHeaderField:@"Cookie"];[request setURL:[a objectAtIndex:0]];[request setHTTPMethod:@"GET"];NSData *returnData = [NSURLConnection sendSynchronousRequest:requestreturningResponse:nil error:nil];[request release];一、iPhone终端代码：（同步请求）NSString *post = nil;post = [[NSString alloc] initWithFormat:@"message=%@",@"hello,world."];NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];[request setURL:[NSURL URLWithString:@"http://192.168.10.220:18080/data/1.jsp"]];[request setHTTPMethod:@"POST"];[request setValue:postLength forHTTPHeaderField:@"Content-Length"];[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];[request setHTTPBody: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 = [NSURLConnection sendSynchronousRequest:request returningRequest:nil error: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:[httpBodyString dataUsingEncoding:NSUTF8StringEncoding]];////post = [[NSString alloc] initWithFormat:@"message=%@",@"hello,world."];httpBodyString = [arrayData JSONRepresentation];NSData *postData = [httpBodyString dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];[request setHTTPBody:postData];[request setHTTPMethod:@"POST"];//NSURLResponse *reponse;NSError *error = nil;//NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&reponse error:&error];if (error) {NSLog(@"Something wrong: %@",[error description]);}else {if (responseData) {NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];NSLog(@"get %@",responseString);}}NSMutableDictionary *dgetData = [responseString JSONValue];NSLog(@"dgetData: %@" , [dgetData description]);[dlist release];[arrayData release];
