iOS POST请求 有中文的时候
镔哥，最近post请求遇到一些问题，当有中文的时候是请求不成功
下面镔哥写两种案例：
1：通常post请求：（有中文不成功）
//1:设置URL
NSString *host = HOST;
NSString *usename = @"fuck";
NSString *queryString = [NSStringstringWithFormat:@"/app/clickTableScreen?userName=%@&idfa=%@&operator=%@&systemVersion=%@&networkState=%@&deviceName=%@&memorySize=%@&model=%@",usename,adId, [self checkCarrier],phoneVersion,netStr,userPhoneName,totalDiskSpaceStr, [LoginViewControllerdeviceString]] ;
NSLog(@"querString:%@",queryString);
//完整的设置参数
NSString *urlString = [NSStringstringWithFormat:@"%@%@",host,queryString];
NSLog(@"参数：%@",urlString);
//得到完整的url
NSURL *url1 = [NSURLURLWithString:urlString];
//2:Request请求
NSMutableURLRequest *request = [[NSMutableURLRequestalloc]initWithURL:urlcachePolicy:NSURLRequestUseProtocolCachePolicytimeoutInterval:10];
[request setHTTPMethod:@"POST"];
//第三步，连接服务器
NSError * error = nil;
NSData *reqData = [NSURLConnectionsendSynchronousRequest:request returningResponse:nilerror:&error];
// //3:将请求转换二进制
// NSData *reqData = http://www.mamicode.com/[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
if(reqData =http://www.mamicode.com/= nil){
if(error){//这样写有个好处，就是如果解析数据不成功，系统会列出原因，我就因为写了这句话才知道出现什么原因：（Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo=0x14ed24c0 {NSUnderlyingError=0x）
NSLog(@"error = %@", error);
}
UIAlertView * alert = [[UIAlertViewalloc] initWithTitle:@"提示"message:@"网络不稳定，请稍后尝试！"delegate:nilcancelButtonTitle:@"取消"otherButtonTitles:@"ok",nil];
[alert show];
return;
}else{
NSLog(@"error = %@", error);
}
NSDictionary *reqDic=[NSJSONSerializationJSONObjectWithData:reqData options:NSJSONReadingAllowFragmentserror:nil];
NSString *info = [NSStringstringWithFormat:@"%@",[reqDicobjectForKey:@"info"]];
NSLog(@"参数字典：%@",reqDic);
//4:打印数据
NSString *errcode = [NSStringstringWithFormat:@"%@", [reqDicobjectForKey:@"errcode"]];
if ([errcode isEqualToString:@"0"]) {
NSLog(@"成功了");
}else
{
UIAlertView *alert = [[UIAlertViewalloc]initWithTitle:@"获取广告标识符失败"message:info delegate:selfcancelButtonTitle:@"确定"otherButtonTitles:nil,nil];
[alert show];
}
}

NSLog(@"querString:%@",queryString);
//完整的设置参数
NSString *urlString = [NSString stringWithFormat:@"%@%@",host,queryString];
NSLog(@"参数：%@",urlString);
//得到完整的url
//有中文的时候要转码
NSString * urlstr = [urlStringstringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
NSURL * url = [NSURLURLWithString:urlstr];
//2:Request请求
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10];
