Bluemix推送通知，當訂閱標籤達到400時

我調用let push = IMFPushClient.sharedInstance() logger?.logInfoWithMessages("subscribe to tags: \(tagsArray)") push.subscribeToTags([tagsArray]) { (response: IMFResponse!, error: NSError!) -> Void in 訂閱標籤，但從堆棧跟蹤獲得400。Bluemix推送通知，當訂閱標籤達到400時

在嘗試訂閱時，我可以在錯誤中看到您提供了無效的JSON。如果您嘗試訂閱所有可用的標籤，則首先需要獲取可用的標籤，然後在訂閱時使用這些標籤。例如：

夫特：

push.retrieveAvailableTagsWithCompletionHandler 
{ 
(response: IMFResponse!, error: NSError!) -> Void in 
    let tags = response.availableTags() 
    if (tags.count > 0) 
{ 
    //lets subcribe to all tags for demo purposes 
    push.subscribeToTags(tags, completionHandler: 
    { (response: IMFResponse!, error: NSError!) -> Void in 
    }) 
} 
}

這裏是文檔提供進一步的深入瞭解：

謝謝，約什。我在服務器上有「測試」標籤，我可以通過儀表板看到它。那麼我做push.subscribeToTags（[「測試]），標籤是唯一需要的參數。json中的哪個參數是無效的？它是否需要設備ID？我訂閱標籤前註冊了設備。訂閱所有可用的標籤手機只訂閱標籤的一個子集 –

嗨喬希，經過一些測試後，我發現如果設備訂閱了它已經提交的標籤，它將會失敗，例如，如果它有訂閱「tag1」時，subscribeToTags（[「tag1」，「tag2」]）將失敗，代碼爲400.此時，它仍然訂閱了「tag1」，但沒有訂閱「tag2」。標籤，並只訂閱可用的內容。 –
