NSLocalizedDescription=Request f

解决方法:

修改AFNetworking中AFURLResponseSerialization.m文件

在226行,将

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

改成

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

增加了一个@"text/html"
