  3 | 
  4 | php项目基于微信支付JS SDK和JS API的接入开发
  5 | 
  6 | 因为php框架繁多，而且项目开发进度比较赶，线上代码迁移出来的时间也有限，此处的代码没有经过备案域名和线上服务器测试，肯定会有很多问题，所以样例代码仅供参考
  7 |

 10 | ### 前言
 11 | 
 12 | 因为抢红包风波，微信封杀了支付宝链接，不得不紧急加入微信支付。
 13 | 
 14 | 微信支付的开发文档太坑，不才已被虐哭，趁现在还在坑里，记录一下留个纪念。
 15 |

 35 | 
 36 | ### 注意点
 37 | 
 38 | * 微信5.0后的版本才支持微信支付
 39 | 
 40 | * 微信支付的jssdk接口只能在微信客户端里面才有效果，普通浏览器无法测试
 41 | 
 42 | * 微信支付的相关代码必须部署在线上，域名必须备案，而且域名必须跟 <微信公众平台> 里相关设置里的域名一致
 43 | 
 44 | * 微信大小写非常敏感，timestamp和timeStamp以及appId和appid不要弄错，要在对的接口使用对的大小写，里面是混着用的
 45 | 
 46 | * 商户号和微信商户号要区分出来，也就是MCHID，开通微信支付后有一封邮件，里面会有相关的信息，登陆商户后台也能找到
 47 | 
 48 | * 只有服务号才能接入微信支付，不同的服务号之前可以跨号支付，订阅号里面不能调用微信支付，会报“不允许跨号支付”的错误
 49 | 
 50 | ### 关于签名
 51 | 
 52 | 我开发的时候遇到三次签名生成：
 53 | 
 54 | 1. wx.config 里面有一次 signature 的签名生成，调用的是官方sdk的方法，它用的是 SHA1 加密，生成之后的签名没有转大写
 55 | 
 56 | 2. 获取prepay\_id的时候，中间会生成一次签名，调用的是官方sdk的方法，它用的是 MD5 加密，生成之后的签名统一转成大写
 57 | 
 58 | 3. wx.chooseWXPay 里面有最后一次 paySign 的签名生成，我调用了步骤2里面的那个接口，最后测试成功了
 59 | 
 60 | ### 分享代码
 61 | 
 62 | 因为目前用的项目的框架是比较奇葩的，我之前已经把官方的代码临时整合并修改成适合项目的代码，不能直接用了，后面的日子将逐步等工作闲暇的时候，整理出直接能用的来分享给还没入坑有需要的童鞋们。

 67 | 
 68 | ### 开发环境
 69 | 
 70 | 本地相关开发环境如下：
 71 | 
 72 | * 编辑器: MacVim
 73 | 
 74 | * php: 5.5.13，接入微信支付的相关扩展都装了，主要应该是curl扩展
 75 | 
 76 | * nginx: 1.4.2
 77 | 
 78 | * 操作系统: Yosemite 10.0.2
 79 | 
 80 | ### 创建相关文件
 81 | 
 82 |     WxPay.pub.config.sample.php => WxPay.pub.config.php // 配置文件
 83 |     access_token.sample.json => access_token.json       // 临时存储access_token
 84 |     jsapi_ticket.sample.json => jsapi_ticket.json       // 临时存储jsapi_ticket
