要使用常規的AFN網絡訪問
-
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
所有的網絡請求,均有manager發起
-
需要注意的是,默認提交請求的數據是二進制的,返回格式是JSON
1> 如果提交數據是JSON的,需要將請求格式設置為AFJSONRequestSerializer
2> 如果返回格式不是JSON的, -
請求格式
AFHTTPRequestSerializer 二進制格式
AFJSONRequestSerializer JSON
AFPropertyListRequestSerializer PList(是一種特殊的XML,解析起來相對容易) -
返回格式
AFHTTPResponseSerializer 二進制格式
AFJSONResponseSerializer JSON
AFXMLParserResponseSerializer XML,只能返回XMLParser,還需要自己通過代理方法解析
AFXMLDocumentResponseSerializer (Mac OS X)
AFPropertyListResponseSerializer PList
AFImageResponseSerializer Image
AFCompoundResponseSerializer 組合
