NSString *lcsUrl = @"http://192.168.1.1:8080/lcsUrl";
//如果网址中有汉字，需要先转码
NSString *word = [NSString stringWithUTF8String:"汉字"];//注意此处到字符串要求传一个c的字符串，没有@
NSString *finaUrl = [NSString stringWithFormat:@"http://192.168.1.1:8080/lcsUrl= %@",word];
NSURL *url = [NSURL URLWithString:lcsUrl];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:url];
request.HTTPMethod = @"GET";
request.timeoutInterval = 60;
NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self];
[connection start];
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(@"请求出错");
}

{
[_data appendData:data];
