NSURL *url = [NSURL here`URLWithString:@"http://testing.appspot.com/json/ListingBusinessService/"]; 
    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url]; 

    httpClient.parameterEncoding = AFJSONParameterEncoding; 

    NSDictionary *params = @{@"params":@"women",@"params" : @"women", @"params":@"women"}; 

    [httpClient registerHTTPOperationClass:[AFJSONRequestOperation class]];

這段代碼的上下文是什麼？你試過什麼解決方案？請詳細說明您的問題，以獲得更好的幫助！ –

什麼是錯誤？什麼不工作？ –

我得到錯誤像AFNetworkingOperationFailingURLRequestErrorKey，錯誤它的打印整個JSON，但在失敗塊 – user2667982

從命令行使用curl調用此URL後，我會說問題是響應內容類型是text/plain而不是application/json。 AFJSONRequestOperation需要application/json ContentType。

< HTTP/1.1 200 OK 
< X-TraceUrl: /appstats/details?time=1390399595248&type=json 
< Content-Type: text/plain; charset=UTF-8

感謝您的答覆，並且我已經更新與應用程序/ JSON代碼，但我是獲取失敗消息 – user2667982

我只是再次嘗試訪問該URL，現在我得到一個HTTP302和contentType ist文本/ HTML – rist
