1、 准备阶段
NSString *urlString = [NSString stringWithFormat:@"http://jssb.zust.edu.cn/androidLogin.action"]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"POST"]; 2、设置头 NSString *contentType = [NSString stringWithFormat:@"text/xml"]; [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 3、数据内容体的设定 NSMutableData *postBody = [NSMutableData data]; [postBody appendData:[[NSString stringWithFormat:@"id=%@&password=%@&role=%@",@"admin02",@"admin02",@"dean"] dataUsingEncoding:NSUTF8StringEncoding]]; [request setHTTPBody:postBody]; XML传送的时候： NSMutableData *postBody = [NSMutableData data]; [postBody appendData:[[NSString stringWithFormat:@"<Request Action=\"Login\">"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"<Body>"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"<Username>wangjun</Username>"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"<Password>password</Password>"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"<PlatformID>2</PlatformID>"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"<PlatformVersion>3.1.3</PlatformVersion>"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"<TaskViewerName>IP 1.3</TaskViewerName>"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"<TaskViewerVersion>3</TaskViewerVersion>"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"</Body>"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"</Request>"] dataUsingEncoding:NSUTF8StringEncoding]]; //post [request setHTTPBody:postBody]; 4、请求响应 NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
