微信支付（不得不吐槽腾讯这个坑货）

谨以此文献给苦苦挣扎在微信支付给我们挖的坑中的程序猿和媛们，百度了很久很久，网络上也没有一个成功的微信支付demo，既然我做成了，本着跟大伙分享的原则，特此奉献出我开发过程中遇到的问题，这是本人亲测的成功案例，而且是v3.0的版本，不是官网的1.7版本！！！

1，项目进展到现在，市场部要求加入微信支付功能，然后去官网下载了demo，研究了一下，同时又百度了一下，腾讯留下的各种坑。差不多花了几天时间搞懂了，谁知道，最大的坑出现了，NND,微信官网提供的demo和开发文档是1.7的，我们产品部通过客服跟腾讯竟然要到了3.0版本的，你说这还能不能愉快的玩微信支付了。好了，不吐槽腾讯了，留给大家自己体会，O(∩_∩)O哈哈~。

2，在微信开放平台申请app_id,app_key我就不在这里叙述了，稍后我会把开发文档一并上传的，你也可以去微信开放平台自行查看(差不多一个周才会通过审核)

3，下面我就来说一说微信支付开发时需要注意的地方：

3.1 首先来看一下，微信支付的架构和流程图





3.2 再来看一下成功调起微信支付的界面



4下面开始讲解配置工程

4.1 这里必须要有wxapi这个包名，同时必须有WXPayEntryActivity这个类名，否则无法调起微信支付，（开发文档没有标注，废了好大周章）



4.2 支付成功通知：在WXPayEntryActivity的OnResp中处理，不能以微信返回的通知界面为准（我遇到的情况，网络不稳定的时候，微信返回界面提示支付失败，但是收到微信通知其实已经支付成功了），必须要去自己的服务器查询支付状态，这里微信建议用轮循机制去查询（最好听微信劝，O(∩_∩)O哈哈~），

5，支付通知接口和退款接口按照开发文档即可，这里不再赘述

6， 在你的项目测试微信支付的时候，一定要用你自己的keystore签名出来测试，如果用debug.keystore肯定是不成功的，切记，切记，不要闹乌龙！！！

好了，就写这么多吧，以此文来祭奠我和同事被腾讯坑死的那几天，如果有不懂的童鞋可以给我留言，大家可以去这个地址下载微信支付v3.0版本的开发文档和demo，以及一个成功的微信支付demo app，轮询事件大家可以参考我的下一篇blog,从别人那里转来的，写的挺详细的
