每次更新ADNetworking都要改，唉
下面是錯誤信息：

獲取服務器響應出錯

error=ErrorDomain=com.alamofire.error.serialization.response

NSLocalizedDescription=Requestfailed: unacceptable content-type: text/html}

對應到自己的項目里面，我用的是AFNetworking這套網絡請求包，需要改的是：

AFURLResponseSerialization.m文件

223行：

self.acceptableContentTypes =[NSSetsetWithObjects:@"application/json", @"text/html"
,@"text/json",@"text/javascript", nil];

加上@"text/html"部分，其實就是添加一種服務器返回的數(shù)據(jù)格式。
