Sure, you are not passing usernameas a GETparameter while getting the http://127.0.0.1:8000/StartPage/page.
当然，您在获取页面时不会username作为GET参数传递http://127.0.0.1:8000/StartPage/。
Try this and observe username printed: http://127.0.0.1:8000/StartPage?username=test.
试试这个并观察用户名打印：http://127.0.0.1:8000/StartPage?username=test。
Use get()and avoid MultiValueDictKeyErrorerrors:
使用get()和避免MultiValueDictKeyError错误：
request.GET.get('username', '')

Make sure the request you are getting doesn't contains disabled. If the field which you are getting contains disabled. It will give this error. So, in order to solve this make sure your don't have a disabledwork in your field. e.g
确保您收到的请求不包含disabled。如果您获取的字段包含disabled。它会给出这个错误。因此，为了解决这个问题，请确保您的领域中没有残疾人工作。例如
<input name="numberid" disabled class="form-control" value="{{p.id}}" type="text"></div>
In my case, the disabledkeyword was causing this error.
就我而言，disabled关键字导致了此错误。
