我目前正在我的应用程序中开发一项功能,该功能将允许用户邀请他们的 Facebook 朋友,为此他们和朋友将收到奖励/礼物。

因此,为此我使用了 Facebook 请求选项。因此,我查看了以下 2 个文档:

https://developers.facebook.com/docs/android/send-requests/

https://developers.facebook.com/docs/android/app-link-requests/

现在,如果两个设备都安装了应用程序并且我从一个设备向另一个设备发送请求并且可以检索发件人使用此方法发送的其他数据,这将非常有用:

    private void getRequestData(final String inRequestId) {
    // Create a new request for an HTTP GET with the
    // request ID as the Graph path.
    Request request = new Request(Session.getActiveSession(), 
            inRequestId, null, HttpMethod.GET, new Request.Callback() {

                @Override
                public void onCompleted(Response response) {
                    // Process the returned response
                    GraphObject graphObject = response.getGraphObject();
                    FacebookRequestError error = response.getError();
                    // Default message
                    String message = "Incoming request";
                    if (graphObject != null) 
                    {
                        CupsLog.d(TAG, "getRequestData -> graphObject != null: "+ graphObject.toString());
                        // Check if there is extra data
                        if (graphObject.getProperty("data") != null) 
                        {
                            CupsLog.d(TAG, "getRequestData -> graphObject.getProperty(data) != null");
                            try 
                            {
                                // Get the data, parse info to get the key/value info
                                JSONObject dataObject = new JSONObject((String)graphObject.getProperty("data"));
                                // Get the value for the key - badge_of_awesomeness
                                String reward = dataObject.getString("reward");
                                // Get the value for the key - social_karma
                                String coffeeCups = dataObject.getString("coffee_cups");
                                // Get the sender's name
                                JSONObject fromObject = (JSONObject) graphObject.getProperty("from");
                                String sender = fromObject.getString("name");
                                String title = sender+" sent you a gift";
                                // Create the text for the alert based on the sender
                                // and the data
                                message = title + "\n\n" + 
                                    "reward: " + reward + 
                                    " coffeeCups: " + coffeeCups;
                            } catch (JSONException e) {
                                message = "Error getting request info";
                            }
                        } else if (error != null) {
                            message = "Error getting request info";
                        }
                        else
                        {
                            CupsLog.d(TAG, "getRequestData -> graphObject.getProperty(data) == null");
                        }
                    }
                    Toast.makeText(SocialFeaturesActivity.this, message, Toast.LENGTH_LONG).show();
                }
        });
    // Execute the request asynchronously.
    Request.executeBatchAsync(request);
}

问题:如果接收者将在 Facebook 中收到此请求,但不会安装它,则此请求会将他重定向到 Google Play 以安装应用程序。在他安装应用程序并第一次打开它之后?有没有办法接收这些数据?

Facebook 建议接收方应在每次应用打开时检查是否有待处理的请求(使用onResume)。您可以使用/{user-id}/apprequests端点检查它,如下所示:

https://developers.facebook.com/docs/graph-api/reference/user/apprequests/

根据其文档,GET 将返回一个请求对象数组。

此人从进行 API 调用的应用收到的请求

获得请求 ID 后,您可以使用以下方法收集其他信息/{request-id}

https://developers.facebook.com/docs/graph-api/reference/request/

处理请求后,将其删除以避免重复。

因为Facebook 在您明确删除请求之前不会删除请求,因此您不需要服务器端代码来进行此交互。
