问题描述

我目前正在开发一个 Golang 应用程序.我从客户端收到一个 JWT 令牌，在 Go 中我需要解码该令牌并获取信息:用户、名称等.我正在检查可用的库处理 JWT 令牌，我来到 https://github.com/dgrijalva/jwt-go，但我不知道如何简单地制作我需要的东西.

I am currently working on a Golang application.I receive a JWT token from the client side and, in Go I need to decode that token and get the information: user, name, etc. I was checking the libraries that are available to handle JWT tokens and I came down to https://github.com/dgrijalva/jwt-go, but I don't see how to simply make what I need.

我有令牌，我需要将信息解码为地图或至少一个 json.我在哪里可以找到如何操作的指南?谢谢！

I have the token and I need to decode the info into a map or at least a json. Where can I find a guide of how to do it? Thank you!

推荐答案

jwt.ParseWithClaimsjwt.Claimsmapjwt.MapClaimsMapClaims
jwt.ParseWithClaimsjwt.Claimsmapjwt.MapClaimsMapClaims
tokenString := "<YOUR TOKEN STRING>"    
claims := jwt.MapClaims{}
token, err := jwt.ParseWithClaims(tokenString, claims, func(token *jwt.Token) (interface{}, error) {
    return []byte("<YOUR VERIFICATION KEY>"), nil
})
// ... error handling

// do something with decoded claims
for key, val := range claims {
    fmt.Printf("Key: %v, value: %v
", key, val)
}
