打开沙箱地址:https://open.alipay.com/develop/sandbox/app
需要获取:AppId、支付宝网关地址、应用私钥、支付宝公钥
注册 https://natapp.cn/
购买免费隧道
注意:需要记住这个 authtoken,配置文件用得到
配置隧道
文件 config 配置
#将本文件放置于natapp同级目录 程序将读取 [default] 段 #在命令行参数模式如 natapp -authtoken=xxx 等相同参数将会覆盖掉此配置 #命令行参数 -config= 可以指定任意config.ini文件 [default] authtoken= 将隧道的authtoken填进去 #对应一条隧道的authtoken clienttoken= #对应客户端的clienttoken,将会忽略authtoken,若无请留空, log=none #log 日志文件,可指定本地文件, none=不做记录,stdout=直接屏幕输出 ,默认为none loglevel=ERROR #日志等级 DEBUG, INFO, WARNING, ERROR 默认为 DEBUG http_proxy= #代理设置 如 http://10.123.10.10:3128 非代理上网用户请务必留空
为什么要使用 NATAPP?
因为要把本地的服务暴露到公网,让支付宝可以调用我们的接口给我们传递数据
com.alipay.sdk alipay-sdk-java 4.35.79.ALL
alipay: appId: xxx # 应用私钥 appPrivateKey: xxx # 支付宝公钥 alipayPublicKey:xxx # 每次重启会变化 notifyUrl: http://ju2jpk.natappfree.cc/api/notify #natapp 代 理 的 url +/alipay/notify,这个是用于启动支付宝回调函数 notify 的接口
应用私钥和支付宝公钥可以用默认的,也可以自己配置,若自己配置的话需要使用支付宝开放平台密钥工具
