@FeignClient(name = "Authorization-API", url = "https://www.reddit.com/api/v1")
public interface AuthorizationApi {

    @RequestMapping(method = RequestMethod.POST, value = "/access_token")
    Token getToken(@PathVariable("grant_type") String grantType,
                      @PathVariable String code,
                      @PathVariable("redirect_uri") String redirectUrl,
                      @RequestHeader(name = "Authorization") String authorizationHeader,
                      @RequestHeader("User-agent") String agent
    );
}

电话：

Token token = authorizationApi.getToken(
                "authorization_code",
                code,
                REDIRECT_URI,
                getAuthorizationCredentials(),
                "porymol");
        System.out.println(token.access_token()); //returns null

令牌记录：

public record Token(String access_token, String token_type, Long expires_in, String scope, String refresh_token) {
}

当我向 Postman 提出请求时，我得到了这样的回应：

{
    "access_token": "token",
    "token_type": "bearer",
    "expires_in": 86400,
    "refresh_token": "token",
    "scope": "read"
}

尝试从令牌获取任何值时返回null
