尝试获取授权网址时出现错误：

Traceback (most recent call last):

    return self.wsgi_app(environ, start_response)

    'The view function did not return a valid response. The'
TypeError: The view function did not return a valid response. The function either returned None or ended without a return statement.

这是失败的代码：

  try:
    url = api.get_authorize_url(scope=None)
    redirect(url)
  except InstagramAPIError as e:
    print(e)

背景：我是python和Web开发的新手，我认为我可以通过创建一个简单的应用程序来学习，该应用程序可以根据标签等不同的搜索条件提取IG图片。任何帮助都会有用。

TypeError: The view function did not return a valid response. The function either returned None or ended without a return statement.

该错误实际上告诉了您所有需要了解的内容。您需要在make_response()中返回一些内容（假设url变量正确无误，并且您有一条路由）。

  try:
    url = api.get_authorize_url(scope=None)
    return redirect(url_for(url))
  except InstagramAPIError as e:
    print(e)
