PHP微信支付开发
1.開(kāi)發(fā)環(huán)境
Thinkphp 3.2.3
微信：服務(wù)號(hào)，已認(rèn)證
開(kāi)發(fā)域名：http://test.paywechat.com (自定義的域名，外網(wǎng)不可訪問(wèn))
2.需要相關(guān)文件和權(quán)限
微信支付需申請(qǐng)開(kāi)通
微信公眾平臺(tái)開(kāi)發(fā)者文檔：http://mp.weixin.qq.com/wiki/home/index.html
微信支付開(kāi)發(fā)者文檔：https://pay.weixin.qq.com/wiki/doc/api/index.html
微信支付SDK下載地址：https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1
3.開(kāi)發(fā)
下載好微信支付PHP版本的SDK，文件目錄為下圖：
把微信支付SDK的Cert和Lib目錄放入Thinkphp，目錄為
現(xiàn)在介紹微信支付授權(quán)目錄問(wèn)題，首先是微信支付開(kāi)發(fā)配置里面的支付授權(quán)目錄填寫(xiě)，
然后填寫(xiě)JS接口安全域。
最后設(shè)置網(wǎng)頁(yè)授權(quán)
這些設(shè)置完，基本完成一半,注意設(shè)置的目錄和我thinkphp里面的目錄。
4.微信支付配置
把相關(guān)配置填寫(xiě)正確。
