Question

我目前正在我的应用程序中开发一项功能，允许用户邀请他们的Facebook好友，为此他们和朋友将获得奖励/礼物。

因此，我使用Facebook请求选项。所以我查看了以下两个文档：

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将请求从一个设备发送到另一个设备并且可以检索发件人使用此方法发送的其他数据，则此功能非常有用：

    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：如果接收方将在Facebook上收到此请求，但未安装此请求，则此请求会将其重定向到Google Play以安装该应用。他安装应用程序后第一次打开它？无论如何都有办法接收这些数据吗？

Answer 1

Facebook建议，如果有待处理的请求，接收方应每次检查应用时检查（使用onResume）。您可以使用/{user-id}/apprequests端点进行检查，如下所示：

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

根据其文档，GET将返回一组请求对象。

此人从进行API调用的应用程序收到的请求

获得请求ID后，您可以使用/{request-id}

收集其他信息

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

处理完请求后，将其删除以避免重复。

因为 Facebook在您明确这样做之前不会删除请求，所以您不需要服务器端代码来进行此交互。

如果未安装应用程序，用户是否会收到Facebook请求数据？
