IOS開發之application/x-www-form-urlencoded ;charset=utf-8

  本來常用的是application/json的這中格式，做ios常用的網絡請求框架AFNetworking，默認也是application/json，前不久就遇到這種接受格式問題，按照網上各種說法，改了AFNetworking的設置，最終還是無法解決問題，最后也放棄了使用AFNetworking。寫了個原生的網絡請求就解決了問題。

代碼如下：

 NSHTTPURLResponse *response = nil;

    NSError *erro = nil;

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:urlStr]];

    request.HTTPMethod = @"POST";
//設置格式
    [request addValue:@"application/x-www-form-urlencoded ;charset=utf-8" forHTTPHeaderField:@"Content-Type"];
//
    [request addValue:@"2" forHTTPHeaderField:@"x-wh-token"];
//用HMAC加密
    NSString *serkey = [NSString hmacsha1:@"" key:key];

    [request addValue:serkey forHTTPHeaderField:@"x-wh-signature"];

     [request setHTTPBody:[body dataUsingEncoding:NSUTF8StringEncoding]];

     NSData *requesData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&erro];
