当用户使用jwt，Oauth2和spring security进行首次请求时，如何在服务层上获取jwt令牌字符串？

Question

I am new in development of micro-services with jwt. Here is my project structure:

First micro-service is used to authenticate users by jwt and Oauth2 using username and password. This microservice is called auth-service.

Login request url is like:

[ http://localhost:9092/oauth/token?username=s@sawai.com&password=randomPassword&grant_type=password][1]

By calling this url we got jwt token like:

{"access_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsib2F1dGgyX2lkIl0sInVzZXJfbmFtZSI6InNAc2F3YWkuY29tIiwic2NvcGUiOlsicmVhZCIsIndyaXRlIl0sInRlbmFudElkIjoic2F3YWkuY29tIiwic3lzdGVtR2VuZXJhdGVkUGFzc3dvcmQiOnRydWUsImlkIjoiNTYzOTFhYzAtZDc4OC00ODEyLThmYWMtODEwZTIyMjdjYmI1IiwiZXhwIjoxNTI0NzMxNzgwLCJhdXRob3JpdGllcyI6WyJST0xFX0FETUlOIl0sImp0aSI6ImY0ZTNmNTM5LWRkNDgtNGMxMy05OTg5LTcwM2E1NWYxMjNlYyIsImVtYWlsIjoic0BzYXdhaS5jb20iLCJjbGllbnRfaWQiOiJ0cnVzdGVkLWFwcCJ9.AS1tXpUcPMgEw63FrvPP-xGBz7qCi14Eqe29rDzTXPg","token_type":"bearer","refresh_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsib2F1dGgyX2lkIl0sInVzZXJfbmFtZSI6InNAc2F3YWkuY29tIiwic2NvcGUiOlsicmVhZCIsIndyaXRlIl0sImF0aSI6ImY0ZTNmNTM5LWRkNDgtNGMxMy05OTg5LTcwM2E1NWYxMjNlYyIsInRlbmFudElkIjoic2F3YWkuY29tIiwic3lzdGVtR2VuZXJhdGVkUGFzc3dvcmQiOnRydWUsImlkIjoiNTYzOTFhYzAtZDc4OC00ODEyLThmYWMtODEwZTIyMjdjYmI1IiwiZXhwIjoxNTI0NzQ2MTgwLCJhdXRob3JpdGllcyI6WyJST0xFX0FETUlOIl0sImp0aSI6IjI1ZmJlY2IyLWRhODgtNDY1ZS1iM2I2LTFlN2NmYjBlYmVjMiIsImVtYWlsIjoic0BzYXdhaS5jb20iLCJjbGllbnRfaWQiOiJ0cnVzdGVkLWFwcCJ9.jSG5zUBzu9yGqnBueU7fkIZV6XhXD8oCkYCerwHkkOw","expires_in":14399,"scope":"read write","tenantId":"sawai.com","systemGeneratedPassword":true,"id":"56391ac0-d788-4812-8fac-810e2227cbb5","email":"s@sawai.com","jti":"f4e3f539-dd48-4c13-9989-703a55f123ec"}

On auth service database we just create a single table called users with following fields:

id varchar(255)

created_on datetime

last_modified_date datetime

email varchar(255)

enabled bit(1)

password varchar(255)

role varchar(255)

system_generated_password bit(1)

tenant_id varchar(255)

validate bit(1)

OK.

Now another micro-service is called company and in company service we have list of users(not same as auth service users, because auth service contains users for multiple micro-services like: Company, Candidate etc).

Now we want to maintain last_logged_on for company users. So admin can check when an user logged in last time.

What we try to do is: When user login using auth service and user type is company user then call company service and update users last_logged_on . For calling company service we need jwt-access-token because urls are secure on company side. So how can we get access token on auth service when we request to get jwt token.

Here is configuration for jwt with spring boot on auth side.

All above config is on auth service side. Now when user request for jwt token on auth, then we want to get access-token value on service layer, so i can call company service by secure url calling.

Please guide me how can we get access-token value when user request for jwt token. If you look in CustomTokenEnhancer then we tried to print access-token there by using following statements:

**System.out.println(accessToken.getRefreshToken());
System.out.println(accessToken.getRefreshToken().getValue());
System.out.println(accessToken.getTokenType());**

But values are similar to: 642e0cf2-9214-42d8-ae85-29e5cdfccef1 But we want actual token here.

Please guide me.

Answer 1

You can use that method

public static final String AUTHORIZATION_HEADER = "Authorization";
public static final String TOKEN_SEPERATOR = " ";

public static String getAccessToken(){
    RequestAttributes requestAttributes = RequestContextHolder.getRequestAttributes();
    if (requestAttributes instanceof ServletRequestAttributes) {
        HttpServletRequest request = ((ServletRequestAttributes)requestAttributes).getRequest();
        return Arrays.asList(request.getHeader(AUTHORIZATION_HEADER).split(TOKEN_SEPERATOR)).get(1);
    }
    return null;
}
