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"
