解析接口
客戶端接口傳輸規(guī)則:
1.用cmd參數(shù)(base64)來(lái)動(dòng)態(tài)調(diào)用不同的接口,接口地址統(tǒng)一為 http://a.lovexpp.com
2.將要傳過(guò)來(lái)的參數(shù)組成一個(gè)數(shù)組，數(shù)組添加timestamp元素(當(dāng)前時(shí)間戳,精確到秒)，將數(shù)組的鍵值按照自然排序從大到小排序
3.將數(shù)組組成 key=valkey=val的形式的字符串，將字符串與XPP_KEY連接在一起,用md5加密一次(32位小寫),得到sign
4.將sign添加到參數(shù)數(shù)組中
5.將參數(shù)數(shù)組轉(zhuǎn)換成json用post請(qǐng)求請(qǐng)求接口地址,key值為param
服務(wù)端接口解析規(guī)則:
1.接收參數(shù)param,將結(jié)果解析json得到參數(shù)數(shù)組
2.取出sign,去掉參數(shù)數(shù)組中的sign
3.將參數(shù)數(shù)組key值按照自然排序從大到小排序
4.將排序后的參數(shù)數(shù)組按照key=valkey=val的形式組成字符串，將字符串與XPP_KEY連接，用md5加密一次(32位小寫)，得到sign
5.將sign與客戶端傳過(guò)來(lái)的sign進(jìn)行比對(duì),如不一樣則可能是中途被篡改參數(shù)，服務(wù)器拒絕此次請(qǐng)求
6.將sign與session中的sign對(duì)比，如果一樣，則為重復(fù)提交，服務(wù)器拒絕此次請(qǐng)求
7.此次的sign存入session
8.執(zhí)行路由cmd(base64解析后),將參數(shù)帶到該方法中
