小编use*_*664的帖子

我有一个base64编码的字符串,我试图用go解密.该字符串包含应忽略的空格.我正在尝试的示例代码:

s := "eyJ0aHJlZURTU2VydmVyVHJhbnNJRCI6IjEzZmU3MWQ0LWQxMGQtNDIyMC1hMjE2LTIwMDZkMWRkNGNiOCIsImFjc1RyY++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++W5zSUQiOiJkN2M0NWY5OS05NDc4LTQ0YTYtYjFmMi0xMDAwMDAwMDMzNjYiLCJtZXNzYWdlVHlwZSI6IkNSZXEiLCJtZXNzYWdlVmVyc2lvbiI6IjIuMS4wIiwiY2hhbGxlbmdlV2luZG93U2l6ZSI6IjAyIn0%3D"

out, err := base64.URLEncoding.DecodeString(s)
if err != nil {
    fmt.Println(err)
    return
}
fmt.Println(string(out))

此代码返回:

输入字节93处的非法base64数据

更改字符串填充后,使用StdEncoding而不是URLEncoding:

s= strings.Replace(s, "%3D", "=", -1)
out, err := base64.StdEncoding.DecodeString(s)
if err != nil {
    fmt.Println(err)
    return
}
fmt.Println(string(out))

输出将是:

{ "threeDSServerTransID": "13fe71d4-D10D-4220-a216-2006d1dd4cb8","acsTrc NSID ":" d7c45f99- 9478-44a6-b1f2-100000003366" , "为messageType": "CREQ", "messageVersion": "2.1.0", "challengeWindowSize": "02"}

如何正确解密字符串？
