1. 现实需求:
外包需要我们调用携程的接口
2. 问题描述:
get可以, 但是post就不行
3. 问题最终解决:
回去看文档, 发现还是再用之前的测试接口, 但是这个post接口在生产环境会变换一个网址, 也就是代理服务器要求变, 比如说以前是用的http://a.com, 现在改为http://a.vip.com, 只会开放给签署合同的商家, 妈的我忘了我也是签约了的, 这个环境问题全都忘掉了
4. 额外需求:
能够传递固定的时间格式
5. 接口调用需求:
1、此接口为分销商接入提供，请求返回参数均为Json格式内容
2、请求接口Url统一参数：AID（分销商ID）、SID（分销商账号ID）例：http://apiproxy.fws.ctripqa.com/apiproxy/soa2/13429/getHotelList?AID=1&SID=503、请求头参数： timestamp 时间戳（例：1521715473339，当前时间<30秒，单位：ms） interfacekey 密钥
requesttype 接口名（见见下表，对应接口传对应RequestType） signature MD5加密串 hoteltype 3
（固定值，透传专用，非透传酒店不要传，透传模式hotelid均为母酒店id）
masterhotelmode T或F（落地模式专用，若传T，落地模式数据聚合至母酒店维度，文档中接口所涉及的hotelId均替换为母酒店id）
加密逻辑：signature=Md5(timestamp+AID+MD5(interfacekey).toUpperCase()+SID+RequestType)
.toUpperCase() 备注： 1）、“代理通分销接口”支持Http交互，请求头参数名统一小写，传入httpHeader交互处理。
2）、传“hoteltype=3”，仅返回透传酒店数据，取数后请自行做标记，透传酒店调用分销所有接口必传该字段；非透传酒店不要传该字段（非透传酒店请求旧版接口保持不变）。
