Sure, you are not passing username as a GET parameter while getting the http://127.0.0.1:8000/StartPage/ page.当然，在获取http://127.0.0.1:8000/StartPage/页面时，您没有将username作为GET参数传递。
Try this and observe username printed: http://127.0.0.1:8000/StartPage?username=test .试试这个并观察打印的用户名： http://127.0.0.1:8000/StartPage?username=test 。
Use get() and avoid MultiValueDictKeyError errors:使用get()并避免MultiValueDictKeyError错误：
request.GET.get('username', '')

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