iOS POST請求有中文的時候

鑌哥，最近post要求遇到1些問題，當有中文的時候是要求不成功

下面鑌哥寫兩種案例：

1：通常post要求：（有中文不成功）

//1:設置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);

//完全的設置參數

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

NSLog(@"參數：%@",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，連接服務器

NSError * error = nil;

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

// //3:將要求轉換2進制

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

if(reqData == nil){

if(error){//這樣寫有個好處，就是如果解析數據不成功，系統會列出緣由，我就由于寫了這句話才知道出現甚么緣由：（Error Domain=NSURLErrorDomain Code=⑴002 "unsupported URL" UserInfo=0x14ed24c0 {NSUnderlyingError=0x）

NSLog(@"error = %@", error);

}

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"網絡不穩定，請稍后嘗試！" 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(@"參數字典：%@",reqDic);

//4:打印數據

NSString *errcode = [NSString stringWithFormat:@"%@", [reqDic objectForKey:@"errcode"]];

if ([errcode isEqualToString:@"0"]) {

NSLog(@"成功了");

}else

{

UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"獲得廣告標識符失敗" message:info delegate:self cancelButtonTitle:@"肯定" otherButtonTitles:nil, nil];

[alert show];

}

2:第2種寫法對照（其實就是加了1句話）

/1:設置URL

NSString *host = HOST;

NSString *usename = @"fuck";

NSLog(@"querString:%@",queryString);

//完全的設置參數

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

NSLog(@"參數：%@",urlString);

//得到完全的url

//有中文的時候要轉碼

NSString * urlstr = [urlString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];

NSURL * url = [NSURL URLWithString:urlstr];

//2:Request要求

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

[request setHTTPMethod:@"POST"];

//第3步，連接服務器

NSError * error = nil;

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

// //3:將要求轉換2進制

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

if(reqData == nil){

NSLog(@"error = %@", error);

}

UIAlertView * alert = [[UIAlertView alloc] initWithTitle:@"提示" message:@"網絡不穩定，請稍后嘗試！"delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:@"ok", nil];
