贴上之前写的代码

所以不管怎么样 还是要最开始还是要完成算法的积累

public String callback(@RequestParam(name = "code") String code,
                           @RequestParam(name = "state") String state,
                           HttpServletResponse response) {
        AccessTokenDTO accessTokenDTO = new AccessTokenDTO();
        accessTokenDTO.setClient_id(clientId);
        accessTokenDTO.setClient_secret(clientSecret);
        accessTokenDTO.setCode(code);
        accessTokenDTO.setRedirect_uri(redirectUri);
        accessTokenDTO.setState(state);
        String accessToken = githubProvider.getAccessToken(accessTokenDTO);
        GithubUser githubUser = githubProvider.getUser(accessToken);
        if (githubUser != null && githubUser.getId() != null) {
            User user = new User();
            String token = UUID.randomUUID().toString();
            user.setToken(token);
            user.setName(githubUser.getName());
            user.setAccountId(String.valueOf(githubUser.getId()));
            user.setAvatarUrl(githubUser.getAvatarUrl());
            userService.createOrUpdate(user);
            Cookie cookie = new Cookie("token", token);
            cookie.setMaxAge(60 * 60 * 24 * 30 * 6);
            response.addCookie(cookie);
            return "redirect:/";
        } else {
            log.error("callback get github error,{}", githubUser);
            // 登录失败，重新登录
            return "redirect:/";
        }
    }
