title: file upload using Vapor
body: <p>I can't find any example of handling file upload, especially how to save into some specific folder.</p>
  
  <p>Here is the code, addVideo is a HTTP POST multipart/form-data:</p>
  
  <pre><code>videos.post("addVideo") { req in
  
      // need to save req.multipart["video"] into /data/videos/
  
      return try JSON(node: ["status": 0, "message": "success"])
  }
  </code></pre>
