jquploader + bottle.py - 不能讓它工作:(

我有一個簡單的bottle.py應用程序讓我上傳文件，現在因爲這些文件可能很大，我想要一個進度條。 jqUploader看起來像是我想要的，但現在我很難讓它工作。我的上傳工作完美，當我有我自己的形式，但現在我不知道如何正確訪問數據了。潘岳：jquploader + bottle.py - 不能讓它工作:(

@route('/upload') 
def upload(): 
    return static_file('upload_form.html', root='html') 

@post('/load_from_file') 
def load_from_file(): 
    print("Uploading...") 
    name = request.forms.name 
    data = request.files.myFile3 
    print(data) 
    filename = data.filename 
    with open(os.path.join("C:\\", filename), "wb") as file_object: 
     bytes = 0 
     while True: 
      datachunk = data.file.read(1024) 
      if not datachunk: 
       break    
      file_object.write(datachunk) 
      bytes += len(datachunk) 
    return "Hello %s! You uploaded <b>%s</b>." % (name, filename)

這裏是工作的代碼（HTML中的JS還是沒有改變任何東西）：

@route('/upload') 
def upload(): 
    #Upload-Form 
    return static_file('upload_form.html', root='html') 

@post('/load_from_file') 
def load_from_file(): 
    #Actual Uploading 
    if request.POST.Upload == 'Submit Query': 
     try: 
      data = request.POST.Filedata.file 
      filename = request.POST.Filename 
      filepath = os.path.join(settings.FOLDERS["TEMP_WORKING"], filename) 
      with open(filepath, "wb") as file_object: 
       while True: 
        datachunk = data.file.read(1024) 
        if not datachunk: 
         break    
        file_object.write(datachunk) 
      process_files_upload(filepath)    
     except: 
      print(traceback.format_exc()) 
     #Check if only uploaded or already finished 
     return "Upload Finished" 
    else: 
     redirect('/upload')
