jwt签名失败并为令牌返回null。这是我的实施:
var jwt = require('jsonwebtoken');
var jwt_session_secret = "rnwR_apwvkWjdHovcmmQuoDwLR8av9oFjbJm2KhS7oEX9aSiBu9e96jxCDM9vj5_x8OlCCEiXwIGkagL-KDgnDsulc2e0QU5qYN75lzomrc4P9gqgGXB7HVfpaBcKgW3oLsXRBWAoFT5ICsOSwT-70hdQtJfE7a3NK6j3jmxcSE";
var payload = { ud: 23 };
var exp = Math.floor((new Date(+new Date + 12096e5).getTime())/1000);
var opts = { issuer: 'gateway', expiresIn: exp };
console.log(payload);
jwt.sign( payload, jwt_session_secret, opts, function(token) {
console.log("token = " + token);
jwt.verify(token, jwt_session_secret, function(err, decoded) {
if(err) {
console.log("Error failed: " + err);
return;
}
console.log("decoded");
console.log(decoded);
});
});
代码看起来不错,但不确定我是否遗漏了一些东西。这是输出:
{ ud: 23 }
token = null
Error failed: JsonWebTokenError: jwt must be provided

您需要在回调中接受两个参数,错误和令牌,如下所示:
jwt.sign( payload, jwt_session_secret, opts, function(err, token) {
