通过webhooks使用MS图Android SDK的事件订阅

问题描述：

我正在使用MS图android SDK实现事件订阅。以下是代码。通过webhooks使用MS图Android SDK的事件订阅

IGraphServiceClient mGraphServiceClient = GraphServiceClientManager.getInstance(context).getGraphServiceClient(); 

mGraphServiceClient.getSubscriptions().buildRequest().post(getSubscription(email, expirationDate), subscriptionICallback); 


private Subscription getSubscription(String email, Calendar expirationDate) { 
     Subscription subscription = new Subscription(); 
     subscription.expirationDateTime = expirationDate; 
     subscription.notificationUrl = "<Webhook link>"; 
     subscription.changeType = "created,updated"; 
     subscription.resource = "me/events"; 
     subscription.clientState = Base64.encodeToString(email.getBytes(), Base64.URL_SAFE | Base64.NO_PADDING | Base64.NO_WRAP); 

     return subscription; 
    }

通过该产生的请求主体总是抛出的错误：

但同样的请求体在图探险家做工精细，我已经尝试了很多东西，现在却无力解决。我怎样才能让这个工作在Android的订阅，我找不到这个在线的任何资源。

您是否搜索了关于骆驼肠衣的错误？ – halfer

是的，但问题应该与请求体有关，但同样的请求在图形浏览器中工作正常。 – Surbhi

答

问题是由于它在默认情况下和订阅API设置"@odata.type":"microsoft.graph.subscription"微软图形SDK的BaseSubscription模型没有在请求体支持这一点，并引发错误：400

所以我通过明确使解决它"@odata.type"到null在订阅模型中，并将其传递给我成功运作的发布请求。

谢谢！
