初识python wxpy模块之swxpay[简易版微信支付]

测试花了不少时间，只要是我想在服务器上跑这个wxpy项目，所以需要在我的服务器上搭python环境，折腾了不少时间，乱码这种问题等，然后又在tomcat上部署一个small【simple mall】项目（目标是做成类似自动发卡系统，现在还在筹划中…页面怎么写【捂脸】有点愁啊）。目前这个small只是完成了支付模块，尚未成型…

先看效果swxpay【simple wxpay:简易微信支付】

前往测试体验

设置了0.5元测试接口的支付金额，实际使用可以自行设定即可

简单介绍一下swxpay优缺点:

优点:

• （1）摆脱申请微信支付繁琐的步骤

  • （a）在线提交营业执照、身份证、银行账户等基本信息，并按指引完成账户验证
  • （b）微信支付团队会在1-2个工作日内完成审核，审核通过后请在线签约，即可体验各项产品能力
  • （c）如需自行开发完成收款，需将商户号与APPID进行绑定，或开通微信收款商业版（免开发）完成收款

• （2）方便个人网站接入微信支付

• （3）支持回调个人网站的第三方接口

• （4）0基础实现支付开发，摆脱微信支付学习成本

缺点:

• （1）可能无法支撑大规模支付
  • （a）可以优化提高
• （2）需要使用一个小号进行绑定二维码收款
  • （a）原理的局限性决定的，是登录网页版微信监听实现消息实现
• （3）服务端需要生成唯一ID传递给支付用户从而确定支付的目标订单
  • （a）通过支付备注传递
• 需要一定的python知识
  • 非必须，因为我都写好了，贴出来即可【奸笑】

话不多说看代码实现吧…

结束语

• 目前代码实现也就是160行左右，现在只是测试阶段，有可能还需要根据具体使用修改部分代码
• 如果你有一定python基础的话可以拿去跑一下，但是提前告知你，肯定会有一系列问题，部署到服务器上问题测试更多的了…
• 如果有时间的话下一篇博客有可以能会介绍如何在window and linux 服务器上部署swxpay（Simple wxpay）
