php完成微信付出之现金红包

网上的良多PHP微信付出接入教程都很是庞杂，且须要设置装备摆设和引入较多的文件，本身经由过程清算后给出一个单文件版的，但愿能够给列位想接入微信付出的带来些许援助和鉴戒意思。

间接运转该文件便可给指定的微信誉户发送现金红包。

须要注重的事变：

1.微信现金红包请求必传证书，须要到这里 账户中间->账户设置->API宁静->下载证书，而后点窜代码中的证书途径

2.默许的利用场景是抽奖（即scene_id参数为PRODUCT_2），额度是1-200元，以是测试时的最低金额是1元。如需点窜在产物中间->产物大全->现金红包->产物设置中点窜

3.该文件需放到付出受权目次下，能够在微信付出商户平台->产物中间->开辟设置装备摆设中设置。

4.如提醒署名毛病能够经由过程微信付出署名考证东西遏制考证：微信公家平台付出接口调试东西

5.毛病码参照 ：地点

代码以下：
