篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了golang 支付宝SHA1withRSA加密相关的知识,希望对你有一定的参考价值。
SHA1大家用的挺多,RSA不多但用的也有,但像支付宝这样要求 SHA1 + RSA的恐怕就没几个了,写起来实在痛苦。而且一搜一片,却没几个能跑起来的。
刚才有个人在QQ上加我,问之前在支付宝集成的帖子里的SHA1withRSA是咋解决的。说实话,不是专门研究加密的,鬼知道报的错是什么玩意,比如这个:
signature, err := rsa.SignPKCS1v15(rand.Reader, this.privateKey,
crypto.SHA1, hashed) //ParsePKCS8PrivateKey err asn1: structure error: tags don't match (16 vs {class:0 tag:2 length:129 isCompound:false}) {optional:false explicit:false application:false defaultValue:<nil> tag:<nil> stringType:0 timeType:0 set:false omitEmpty:false} AlgorithmIdentifier
反正我是真心看的莫名其妙,不过不妨碍我们解决它,由于调用的是系统加密,所以基本可以肯定是套路问题。以下是在beego中集成支付宝的代码,大家可以参考下:

fmt.Println("AliAnswerController=============get") //接收manager登录支付宝付款授权页面后 支付宝传递过来的回调信息

如果,当然希望没有这个如果,按照上面的法子依然存在问题,大家可以去github搜下go alipay,再试试看吧。
