AFNetWorking Request failed: unacceptable content-type: text/html

今天寫了一個快遞查詢的功能，使用的是AFNetWorking框架，

貼個代碼：

dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
        NSDictionary *dict=@{@"key": @"key",@"com": @"shentong",@"cno": @"768938779991"};
        NSString* encodedString = [@"http://api.kuaidiwo.cn:88/api/" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        [appdelegate.manager POST:encodedString parameters:dict success:^(AFHTTPRequestOperation *operation, id responseObject) {
            NSLog(@"%@",responseObject);
        } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
            NSLog(@"%@",error);
        }];
    });

紅色的是請求連接，好了，按說是沒問題（可是若是別人寫後臺不規範，明明傳回來的是json，可是寫後臺那個鳥非要寫：

） 把返回的內容類型寫成"text/html",由於 AFNetWorking框架是解析不了這種類型的，因此就會報錯，這時候抱怨那老鳥是沒用的，難道你想拿板磚拍他麼～仍是好好改你的代碼吧！
若是規範寫，應該這樣寫： response.setContentType("text/html");
  response.getWriter().write(json)

For JSON:

Content-Type: application/json

response.setContentType(application/json");

For JSON-P:

Content-Type: application/javascript

請參考：
http://stackoverflow.com/questions/477816/what-is-the-correct-json-content-type

因此，咱們必需要設置咱們的解析器：
self.manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

加上這句話，

這時候運行，若是你的請求方式是post，那我就呵呵了，我也是這樣，後來報錯，苦逼～

錯誤代碼：

2014-10-14 22:43:32.953 測試快遞[5208:60b] Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)"

原諒我英語那麼差，我也不知道問題錯哪了，調了一下午，無心間把post改稱get，那麼問題來了，到底對不對呢？恭喜本身，真的對了～
