{
    path: './tmp/',
    usekeyasname: false
}

• path - file upload directory
• usekeyasname - when saving, use the form data keys as file names

return object json:

    {
        "status": "upload",
        "error": null,
        "upload": {
            "test2": "upload",
            "test": "upload"
        }
    }

• status - the result of downloading files, there are 3 types
  • error - no files uploaded
  • witherrors - not all files uploaded
  • upload - all files uploaded without errors
• error - error text
• upload - Object key (name post data) - value (download result: upload - if uploaded, or error text)

if you use promise and no file is uploaded, the reject of string type will be returned
