Javascript 有效JWT对于nestJS guard无效

我正在通过凭证头将JWT从我的客户端应用程序（nextJS with）传递到我的后端nestJS应用程序（使用graphQL）。在我的nestJS后端应用程序中，我试图实现一个auth guard，因此我在JWT.strategy.ts中使用一个自定义函数提取JWT

但是JwtStrategy不接受我的有效签名令牌。为了证明JWT是有效的，我为令牌添加了一些控制台输出。但是从未调用

validate（）

函数。我不明白为什么，因为令牌可以通过

jwt验证。验证
：

JWT: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VyIjp7InVzZXJJZCI6MTIzLCJ1c2VybmFtZSI6InVzZXJuYW1lIiwiaXNBZG1pbiI6dHJ1ZX0sImlhdCI6MTYwOTY3NTc4Nn0.LQy4QSesxJR91PyGGb_0mGZjpw9hlC4q7elIDs2CkLo
Secret: uGEFpuMDDdDQA3vCtZXPKgBYAriWWGrk
Decoded: {
  user: { userId: 123, username: 'username', isAdmin: true },
  iat: 1609675786
}

这是我的输出-它由
jwt.verify（）
解码：

我不知道我遗漏了什么，甚至不知道如何调试它，因为我的jwt.strategy.ts中没有输出，并且根本没有调用validate函数

令牌是在服务器端（nextJS api页面）创建的，具有：

我从您的jwt.strategy.ts文件中的nestJS文档示例中看到了两个不同之处，您可以更改并尝试一下


同步提取器和非异步提取器
默认情况下，passport jwt提取器是一个同步而非异步的提取器，因此您可以尝试更改提取器并删除异步，或者在调用它时添加wait

,，
从authHeaderAbarerToken函数中查找

所以还是改变你的想法

const cookieExtractor = async (req) => {

到

或者-在调用时添加wait

jwtFromRequest: await cookieExtractor(),

打电话给提取器，而不仅仅是传递它
根据JwtStrategy构造函数中的docs示例，他们调用提取器，而不像您那样传递它

jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),

因此，尝试在您的JwtStrategy构造函数中调用它

jwtFromRequest: cookieExtractor(),    // (again - take care of sync / async)

哇，谢谢。过去几天我都没看到。谢谢你的好球。就在第一点做到了。传递函数是可以的，您不必调用它。我只需要删除
async
