实施 Facebook 营销的正确方法 API 创建新的 Feed 调用？

Question

我正在尝试通过 Facebook 营销 API 创建新的数据源。虽然我已经能够创建一个新的提要，但出于某种原因，我的 URL 和 Schedule 参数没有传递给 Facebook，只有提要的名称。

代码

public static String createNewFeed(String catalogId) throws IOException {

        HttpSession session = SessionUtils.getSession();

        String token = (String) session.getAttribute("FacebookAuthToken");

        URL url = new URL("https://graph.facebook.com/" + catalogId + "/product_feeds?name=WalkerWorks_Product_Feed"
                + "&url=https://www.walkerworks.me/feed.xhtml?user=" + session.getAttribute("dbId")
                + "&interval=hourly&hour=1&access_token=" + token);

        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setRequestMethod("POST");
        connection.connect();

        BufferedReader in;
        StringBuffer response = null;
        String input;

        // Creating a BufferedReader and StringBuffer to read connection response.
        in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
        response = new StringBuffer();

        // While there is more information to be parsed, append it to the response
        // StringBuffer.
        while ((input = in.readLine()) != null) {

            response.append(input);

        }

        // Close the connection and parse the StringBuffer.
        in.close();

        Gson gson = new Gson();

        FacebookUserIDModel model = gson.fromJson(response.toString(), FacebookUserIDModel.class);

        System.out.println("Response: " + response.toString());

        return model.getId();

    }

显然我在 URL 中有参数，我正在发送到 Facebook。我想知道我是否正确格式化或创建了计划对象。我认为这是我唯一可能出错的地方，因为其他调用在我发送的完全相同的 url 下正常工作。

Facebook 表示这是通话要求：

Facebook Marketing API / Feed API Call

这是创建的提要。产品未上传，我设置的时间表未创建：

Dynamic Feed Creation on Facebook

如有任何帮助，我们将不胜感激。感谢阅读。

原来我需要在请求中将时间表作为 json 对象提交。这个答案功能齐全。

public static String createNewFeed(String catalogId) throws IOException {

        HttpSession session = SessionUtils.getSession();

        String token = (String) session.getAttribute("FacebookAuthToken");
        
        HttpClient httpClient = HttpClientBuilder.create().build();
        
        HttpPost request = new HttpPost("https://graph.facebook.com/" + catalogId + "/product_feeds?name=WalkerWorks_Product_Feed"
            + "&access_token=" + token);
        
        StringEntity params = new StringEntity("schedule={\"url\":\"https://www.walkerworks.me/feed.xhtml?user=" + session.getAttribute("dbId") + "\","
                + "\"interval\":\"hourly\"}");
        
        request.addHeader("content-type", "application/x-www-form-urlencoded");
        request.setEntity(params);
        
        System.out.println(EntityUtils.toString(request.getEntity()));
        
        HttpResponse response = httpClient.execute(request);

        /*
         * URL url = new URL("https://graph.facebook.com/" + catalogId +
         * "/product_feeds?name=WalkerWorks_Product_Feed" +
         * "&url=https://www.walkerworks.me/feed.xhtml?user=" +
         * session.getAttribute("dbId") + "&interval=hourly&hour=1&access_token=" +
         * token);
         * 
         * HttpURLConnection connection = (HttpURLConnection) url.openConnection();
         * connection.setRequestProperty("Content-Type", "application/json; utf-8");
         * connection.setRequestMethod("POST"); connection.setDoOutput(true);
         * connection.connect();
         */

        /*
         * BufferedReader in; StringBuffer response = null; String input;
         * 
         * // Creating a BufferedReader and StringBuffer to read connection response. in
         * = new BufferedReader(new InputStreamReader(connection.getInputStream()));
         * response = new StringBuffer();
         * 
         * // While there is more information to be parsed, append it to the response //
         * StringBuffer. while ((input = in.readLine()) != null) {
         * 
         * response.append(input);
         * 
         * }
         */

        /*
         * // Close the connection and parse the StringBuffer. in.close();
         */

        Gson gson = new Gson();

        System.out.println("Response: " + response.toString());
        
        FacebookUserIDModel model = gson.fromJson(EntityUtils.toString(response.getEntity()), FacebookUserIDModel.class);

        return model.getId();

    }
