-------------------------------------------------------------------------------- 1 | # django-wechat-pay 2 | 通过 Django, Django Rest Framework, [wechatpy](https://github.com/jxtech/wechatpy) 实现微信小程序端的支付功能 3 | 4 | ## 简要指南 5 | 6 | ### server 端 7 | 商户系统先调用该接口在微信支付服务后台生成预支付交易单，返回正确的预支付交易回话标识后再在APP里调起支付 8 | 9 | 克隆该项目到本地目录 10 | ``` 11 | cd django-wechat-pay/server/djangoWechat/ 12 | pip install -r requirements.txt 13 | python3 manage.py runserver 14 | ``` 15 | 16 | #### 配置支付参数 17 | 配置文件路径： 18 | django-wechat-pay/server/djangoWechat/djangoWechat/settings.py 19 | 20 | ``` 21 | # wechat config 22 | WECHAT = { 23 | 'APPID': 'appid', # 小程序ID 24 | 'APPSECRET': 'appsecret', # 小程序SECRET 25 | 'MCH_ID': 'mch_id', # 商户号 26 | 'TOTAL_FEE': '1', # 总金额 27 | 'SPBILL_CREATE_IP': '127.0.0.1', # 终端IP 28 | 'NOTIFY_URL': 'http://127.0.0.1:8000/wxpayNotify', # 通知地址 29 | 'TRADE_TYPE': 'JSAPI', # 交易类型 30 | 'MERCHANT_KEY': 'merchant_key', # 商户KEY 31 | 'BODY': '商品描述', # 商品描述 32 | } 33 | ``` 34 | 35 | #### 接口地址 36 | 支付接口：http://127.0.0.1:8000/wxpay/ 37 | 通知接口：http://127.0.0.1:8000/wxpayNotify 38 | 39 | ### client 端 40 | 通过微信开发者工具新建项目，将 APPID 替换成你拥有权限的 APPID 进行测试及后续开发… 41 | 42 | 暂时只提供了基本的支付演示，server 端启动成功的前提下小程序载入编译后会立即调起支付接口，使用当前开发者的微信即可支付。 43 | 44 | ## 其他 45 | 该 demo 只做了简单的支付功能，现金红包、企业付款、订单查询、退款等有空再加上… 46 | 47 | ## ONE MORE THING... 48 |
