ios 发送http协议请求消息

- (IBAction) sendHttp : (id) sender{

//此处进行GET方式 发送http请求

//如有中文要进行NSUTF8StringEncoding编码

NSString *urlString =[[NSString stringWithFormat:@"http://192.168.0.110/Login?user=test"

stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

//初始化http请求,并自动内存释放

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];

//同步返回请求，并获得返回数据

NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error];

NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];

//请求返回状态，如有中文无法发送请求，并且stausCode 值为 0

NSLog(@"response code:%d",[urlResponse statusCode]);

if([urlResponse statusCode] >= 200 && [urlResponse statusCode] <300){

NSLog(@"response:%@",result);
