镔哥，最近post要求遇到1些问题，当有中文的时候是要求不成功
下面镔哥写两种案例：
1：通常post要求：（有中文不成功）
//1:设置URL
NSString *host
= HOST;
NSString *usename = @"fuck";
NSString *queryString = [NSString stringWithFormat:@"/app/clickTableScreen?userName=%@&idfa=%@&operator=%@&systemVersion=%@&networkState=%@&deviceName=%@&memorySize=%@&model=%@",usename,adId, [self checkCarrier],phoneVersion,netStr,userPhoneName,totalDiskSpaceStr, [LoginViewController deviceString]] ;
NSLog(@"querString:%@",queryString);
//完全的设置参数
NSString *urlString = [NSString stringWithFormat:@"%@%@",host,queryString];
NSLog(@"参数：%@",urlString);
//得到完全的url
NSURL *url1 = [NSURL URLWithString:urlString];
//2:Request要求
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10];
[request setHTTPMethod:@"POST"];
//第3步，连接服务器
NSError * error = nil;
NSData *reqData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];
// //3:将要求转换2进制
// NSData *reqData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
if(reqData == nil){
if(error){//这样写有个好处，就是如果解析数据不成功，系统会列出缘由，我就由于写了这句话才知道出现甚么缘由：（Error Domain=NSURLErrorDomain Code=⑴002 "unsupported URL" UserInfo=0x14ed24c0 {NSUnderlyingError=0x）
NSLog(@"error = %@", error);
}
UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"网络不稳定，请稍后尝试！" delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"ok", nil];
[alert show];
return;
}else{
NSLog(@"error = %@", error);
}
NSDictionary *reqDic=[NSJSONSerialization JSONObjectWithData:reqData options:NSJSONReadingAllowFragments error:nil];
NSString *info = [NSString stringWithFormat:@"%@",[reqDic objectForKey:@"info"]];
NSLog(@"参数字典：%@",reqDic);
//4:打印数据
NSString *errcode = [NSString stringWithFormat:@"%@", [reqDic objectForKey:@"errcode"]];
if ([errcode isEqualToString:@"0"]) {
NSLog(@"成功了");
}else
{
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"获得广告标识符失败" message:info delegate:self cancelButtonTitle:@"肯定" otherButtonTitles:nil, nil];
[alert show];
}
}

NSLog(@"querString:%@",queryString);
//完全的设置参数
NSString *urlString = [NSString stringWithFormat:@"%@%@",host,queryString];
NSLog(@"参数：%@",urlString);
//得到完全的url
//有中文的时候要转码
NSString * urlstr = [urlString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
NSURL * url = [NSURL URLWithString:urlstr];
//2:Request要求
