iOS POST请求有中文的时候

浏览数：24 / 时间：2015年06月11日

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 = [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);

//完整的设置参数

NSString *urlString = [NSString stringWithFormat:@"%@%@",host,queryString];

NSLog(@"参数：%@",urlString);

//得到完整的url

NSURL *url1 = [NSURL URLWithString:urlString];

//2:Request请求

NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10];

[request setHTTPMethod:@"POST"];

//第三步，连接服务器

NSError * error = nil;

NSData *reqData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];

// //3:将请求转换二进制

// 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 = [[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:@"获取广告标识符失败" message:info delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];

[alert show];

}

2:第二种写法对比（其实就是加了一句话）

/1:设置URL

NSString *host = HOST;

NSString *usename = @"fuck";

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 = [urlString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];

NSURL * url = [NSURL URLWithString:urlstr];

//2:Request请求

NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10];

[request setHTTPMethod:@"POST"];

//第三步，连接服务器

NSError * error = nil;

NSData *reqData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];

// //3:将请求转换二进制

// NSData *reqData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];

if(reqData == nil){

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];
