本文详细介绍了如何针对Javashop 7.0版本进行小程序支付功能的二次开发，包括代码修改和数据库结构调整，特别强调了与7.02版本的对比及退款流程的调整。

本文仅适合Javashop 7.0 版本

需求:拿到商城代码之后小程序无法使用支付

说明:下面内容属于二次开发内容，不受技术支持。

说明：7.0 版本不支持小程序支付，下面全部都是我自己修改的。

小程序支付修改

官方说了，7.02 才有https小程序，之前没有小程序支付，需要修改/增加地方

可以参考7.02代码

需要增加/修改下面地方

修改思路：

找到7.02 ‘MINI’ 字符，对照7.0 增加相应内容

特别注意退款什么的都需要修改

表结构有变动：es_payment_method

因7.02 增加了

plugin/weixin/exception

/plugin/weixin/signaturer

需要从源代码里面移动过来

数据库修改

小程序支付和登录前台Admin UI 直到7.02都尚未有设置界面，需要修改数据

需要修改下面地方

es_payment_method 表增加字段mini_config (longtext)，添加支付参数

注意:这里经常犯的错误就是填了公众号一模一样的参数，小程序支付必须使用小程序APPID。

修改表 es_connect_setting

Config 字段里面内容增加为（粗体部分）

[{"name":"PC网页端参数","configList":[{"key":"wechat_pc_app_id","name":"app_id","value":"luozhuang"},{"key":"wechat_pc_app_key","name":"app_key","value":"luozhuang"}]},{"name":"微信网页端参数","configList":[{"key":"wechat_wechat_app_id","name":"app_id","value":"luozhuang"},{"key":"wechat_wechat_app_key","name":"app_key","value":"luozhuang"}]},{"name":"原生-APP参数","configList":[{"key":"wechat_app_app_id","name":"app_id","value":"luozhuang"},{"key":"wechat_app_app_key","name":"app_key","value":"luozhuang"}]},{"name":"RN-APP参数","configList":[{"key":"wechat_rn_app_id","name":"app_id","value":"luozhuang"},{"key":"wechat_rn_app_key","name":"app_key","value":"luozhuang"}]},{"name":"小程序参数","configList":[{"key":"wechat_miniprogram_app_id","name":"app_id","value":"luozhuang"},{"key":"wechat_miniprogram_app_key","name":"app_key","value":"luozhuang"}]}]
