1>?如果提交數(shù)據(jù)是JSON的,需要將請(qǐng)求格式設(shè)置為AFJSONRequestSerializer
2>?如果返回格式不是JSON的,
3.?請(qǐng)求格式
AFHTTPRequestSerializer????????????二進(jìn)制格式
AFJSONRequestSerializer????????????JSON
AFPropertyListRequestSerializer????PList(是一種特殊的XML,解析起來相對(duì)容易)
4.?返回格式
AFHTTPResponseSerializer???????????二進(jìn)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
