我可以从错误中看出，您在尝试订阅时提供的JSON无效。如果您尝试订阅所有可用标记，则首先需要获取可用标记，然后在订阅时使用这些标记。例如：

斯威夫特：

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
   })
 }
}

以下是提供进一步见解的文档：

谢谢，Josh。我在服务器上有“Test”标记，我可以通过仪表板看到它。然后我做push.subscribeToags（[“Test]”），标记是唯一需要的参数。json中的哪个参数无效？它是否需要设备id？我在订阅标记之前注册了设备。我无法订阅所有可用的标记。移动设备只订阅标记的子集。嗨，Josh，经过一些测试，我发现设备是否订阅了一个标记，即它有subcribed已经存在，它将失败。例如，如果它订阅了“tag1”，subscribeToTags（[“tag1”，“tag2”]）将失败，代码为400。此时，它仍然订阅了“tag1”，而不是“tag2”。因此，我必须获得可用的标签，并且只订阅可用标签中的标签。
