text/html}

在使用AFNetWorking进行网络请求时，请求不到数据，error的信息显示如上所示。其原因是failed: unacceptable content-type: text/html。

AFNetWorking默认不支持text/html，
AFURLResponseSerialization.m
源码  ->   self.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", nil]; 

那么需要修改一下。

AFHTTPSessionManager *session = [AFHTTPSessionManager
manager];
[session.responseSerializer.acceptableContentTypes
= [NSSet setWithObject:@"text/html"];

over！
