/**
要使用常规的AFN网络访问
1. AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
所有的网络请求,均有manager发起
2.需要注意的是,默认提交请求的数据是二进制的,返回格式是JSON
1>如果提交数据是JSON的,需要将请求格式设置为AFJSONRequestSerializer
2>如果返回格式不是JSON的,
3.请求格式
AFHTTPRequestSerializer 二进制格式
AFJSONRequestSerializer JSON
AFPropertyListRequestSerializer PList(是一种特殊的XML,解析起来相对容易)
4.返回格式
AFHTTPResponseSerializer 二进制格式
AFJSONResponseSerializer JSON
AFXMLParserResponseSerializer XML,只能返回XMLParser,还需要自己通过代理方法解析
AFXMLDocumentResponseSerializer (Mac OS X)
AFPropertyListResponseSerializer PList
AFImageResponseSerializer Image
AFCompoundResponseSerializer组合
