? 最近開發(fā)，用到iOS調(diào)用webService接口(接口地址最后是 wsdl:網(wǎng)絡(luò)服務(wù)描述語言是Web Service的描述語言明刷，它包含一系列描述某個web service的定義婴栽。),首先這里要先了解一下什么是webservice,參考百度百科,這里說道webservice,當然離不開XML,當你要解決一個問題的時候首先要弄明白這個問題.
? ?好了廢話不多說了,說一下我解決的思路,這里我們還是通過http請求的方式調(diào)用webservice的接口方法,通過SOAP方式,這里就是一個標準的請求XML結(jié)構(gòu)如下:
將這個XML作為request的body請求.作為返回數(shù)據(jù),一般也是XML的類型,這里作為一個被AFnetworking慣壞了的孩子殺人的心都有了,但是隨著蘋果原生功能越來越完善,老子就信了你的邪,自己寫了一個,調(diào)用傳參參照af的方式,在方法內(nèi)部進行XML的拼接和解析,XML解析這塊用的是谷歌的GDataXML.
這里有個題外話,如果你這里也要上傳圖片,那么需要和后臺確認,1.直接上傳nsdata數(shù)據(jù)2.把照片的data數(shù)據(jù)base64加密上傳字符串?
