iOS實際上web請求參數中是可以傳遞中文和JSON的，只要對其進行轉義就OK

但是一定要注意在請求地址的前面加上http://

1.先定義請求字符串，給字符串幅值，然后再用stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding將請求參數轉義，然后再把字符串定義為NSURL

NSString *urlStr=[NSString stringWithFormat:@"http://192.168.1.53:8080/MJServer/login?username=%@&pwd=%@",self.username.text,self.pwd.text]; //轉碼 urlStr= [urlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSURL *url=[NSURL URLWithString:urlStr]; // 2.創建請求對象 NSURLRequest *request=[NSURLRequest requestWithURL:url];

2.json傳遞時可以用字典

NSString *urlString = @"http://192.168.1.53:8080/MJServer/login"; NSDictionary *param = @{@"phone":@""}; urlString = [urlString stringByAppendingString:[self toJSONString:param]]; urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; NSLog(@"hhhhh......%@",urlString); NSURL *url = [NSURL URLWithString:urlString]; NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url]; [urlRequest setHTTPMethod:@"GET"]; [urlRequest setTimeoutInterval:30.0f]; NSLog(@"哼哼。。%@",urlRequest); NSOperationQueue *queue = [[NSOperationQueue alloc] init]; [NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *connectionError) { if ([data length] > 0 && connectionError == nil) { NSString *html = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding]; NSLog(@"呵呵。。。%@",html); } else if ([data length] == 0 && connectionError ==nil ) { NSLog(@"Nothing was downloaded!"); } else { NSLog(@"%@",connectionError); } }]; }//這個函數就是將字典封裝成轉義的JSON字符串- (NSString *)toJSONString:(NSDictionary *)dict{ NSError *error; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dict options:NSJSONWritingPRettyPrinted error:&error]; NSString *str = [[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding]; str = [NSString stringWithFormat:@"%@",str]; return str;}
