C#实现支付宝转账功能
环境
.net 6
AlipaySDKNet.OpenAPI 2.4.0
申请证书
登录支付宝开放平台https://open.alipay.com/
进入控制台
授权回调地址也设置一下，加密方式AES
新建.net 6空白的web项目
证书除了java都需要自己生成一下pkcs1的密钥
privatekey.txt就是根据应用私钥生成的pkcs1密钥
安装AlipaySDKNet.OpenAPI 2.4.0
配置json
"AliPayConfig": {
"ServerUrl": "https://openapi.alipay.com",
"AppId": "",//参考appCertPublicKey_{APPID}.crt
"PrivateKey": "AliPay/privatekey.txt",
"AlipayPublicKey": "AliPay/publickey.txt",
