根因分析

尝试在Starlette实例上使用add_middleware方法，但该方法在旧版本中不可用或对象错误。

English

Trying to use add_middleware method on a Starlette instance, but the method is not available in older versions or incorrect object.

generic

解决方案

  1. 90% 成功率 Use correct middleware registration syntax 
    app.add_middleware(MiddlewareClass)
  2. 85% 成功率 Check Starlette version and upgrade if needed 
    pip install --upgrade starlette

无效尝试

常见但无效的做法:

  1. Assuming Starlette has the same API as Flask 70% 失败

    Starlette uses different middleware registration.

  2. Using add_middleware on a middleware class instead of app 80% 失败

    Method exists on app, not middleware.
