Facebook OAuth认证异常：非开发用户跳转「功能不可用」页面求助

我们已将Facebook OAuth集成至应用注册流程，用于验证新申请者身份并获取其社交平台信息存储审核，审核通过后方可授予应用全权限。

具体流程说明 #

前端授权链接 #

前端提供的Facebook授权链接：
https://www.facebook.com/v22.0/dialog/oauth?client_id={our_id}&redirect_uri=https%3A%2F%2F{our_url}%2Foauth%2Ffacebook%2Fcallback&scope=email%2Cpublic_profile%2Cpages_show_list%2Cpages_read_engagement&state=${encodedState}

回调URL执行操作 #

授权成功后，回调URL依次执行以下操作：

1. 通过code获取Facebook access token

public InstagramTokenResponse getFacebookAccessToken(String code, String redirectUrl) throws Exception {
        URI uri = new URI(String.format("https://graph.facebook.com" + "/v22.0/oauth/access_token?client_id=%s&redirect_uri=%s&client_secret=%s&code=%s", facebookClientId, redirectUrl, facebookClientSecret, code));
        log.info("Getting facebook access token " + uri.toString());
        return restTemplate.getForObject(uri, InstagramTokenResponse.class);
    }

2. 使用access token获取用户详情

public FacebookUserDataResponse getFacebookUser(String accessToken) throws Exception {
        URI uri = new URI(String.format("https://graph.facebook.com" + "/v22.0/me?fields=id,name,email&access_token=%s", accessToken));
        log.info("Getting facebook user " + uri.toString());
        return restTemplate.getForObject(uri, FacebookUserDataResponse.class);
    }

3. 获取Facebook页面数据估算粉丝数

try {
            facebookPagesResponse = oAuthServiceClient.getFacebookPages(facebookUserAccessToken);

            for (FacebookPage page : facebookPagesResponse.getData()) {
                String pageAccessToken = page.getAccess_token();
                String pageId = page.getId();
                FacebookPageDetails pageDetails = oAuthServiceClient.getFacebookPageDetails(pageId, pageAccessToken);
                followerCount += pageDetails.getFan_count();
            }
        } catch (Exception e) {
            LOG.info("OAuth failed to get facebook pages or their information");
        }

客户端获取Facebook页面及详情代码 #

public FacebookPagesResponse getFacebookPages(String accessToken) throws Exception {
        URI uri = new URI(String.format("https://graph.facebook.com" + "/me/accounts?access_token=%s", accessToken));
        log.info("Getting facebook pages " + uri.toString());
        return restTemplate.getForObject(uri, FacebookPagesResponse.class);
    }

    public FacebookPageDetails getFacebookPageDetails(String pageId, String pageAccessToken) throws Exception {
        URI uri = new URI(String.format("https://graph.facebook.com" + "/%s?fields=name,fan_count&access_token=%s", pageId, pageAccessToken));
        log.info("Getting facebook page details " + uri.toString());
        return restTemplate.getForObject(uri, FacebookPageDetails.class);
    }

当前问题与疑问 #

我们已获得pages_read_engagement和instagram_basic权限，应用已验证并上线。但非开发团队用户使用该流程时，始终无法完成认证，直接跳转至「Feature Unavailable」页面，从未进入回调URL。内部测试无此问题，猜测是否需要将应用转为Facebook商业类型应用？
