Hi shopify team:
Whether the app development can be fully implemented using server-side code?
The interface for configuring the APP URL is as follows

public void handle() {
        HttpServletRequest request = this.getRequest();

        String shop = request.getParameter("shop");
        log.info("shopify 商家店铺: {}", shop);

        // 判断是否已经注册授权
        UserToThirdPlatform userToThirdPlatform
                = UserToThirdPlatform.dao.findByOpenId(shop, ThirdPlatformEnum.Shopify.getPlatformId());
        if (userToThirdPlatform != null) {
            renderSuccessHtml(request, shop);
            return;
        }

        // 如果未授权，生成 OAuth 授权链接并重定向
        String authUrl = String.format(
                "https://%s/admin/oauth/authorize?client_id=%s&scope=%s&redirect_uri=%s",
                shop, API_KEY, SCOPE, REDIRECT_URI
        );
        log.info("shopify 授权链接: {}", authUrl);
        redirect(authUrl);
    }

The following interfaces are configured with callback addresses

public void callback() {
        HttpServletRequest request = this.getRequest();

        String code = getPara("code");
        String shop = getPara("shop");
        log.info("shopify 商家店铺: {}, code: {}", shop, code);

        // 判断是否已经注册授权
        UserToThirdPlatform userToThirdPlatform
                = UserToThirdPlatform.dao.findByOpenId(shop, ThirdPlatformEnum.Shopify.getPlatformId());
        if (userToThirdPlatform != null) {
            renderSuccessHtml(request, shop);
            return;
        }

        // 获取令牌
        String accessToken = ShopifyService.requestAccessToken(shop, code);
        if (accessToken == null) {
            renderHtml(ShopifyService.failPage());
            output(ShopifyService.failPage(), ReturnCode.FAIL, "失败");
        }

        // 获取商家信息并注册用户
        Users users = ShopifyService.getShopInfoToRegisterUser(shop, accessToken);
        UserService.onRegisterSuccess(getIp(), RegisterMethodEnum.REGISTER_BY_CODE, users, null, 0);

        renderSuccessHtml(request, shop);
    }

But check does not authenticate with the session tokens！！！

Hi Bruce,

Did you use the Remix template to create this app?

HI Liam，
Thank you for your reply，I didn’t create it through remix, I created it manually from partners, and app was completely implemented through JAVA, and it returned HTML through JAVA.

So if you use the Remix template it would handle auth for you, otherwise you’ll need to adjust our authentication instructions here for your specific tech stack.
