Root Cause

A route parameter expected as an integer is passed as a string without conversion.

generic

中文

预期为整数的路由参数以字符串形式传递，未进行转换。

Workarounds

  1. 90% success Convert the parameter to int explicitly 
    async def get_item(item_id: str):
    item_id = int(item_id)
  2. 95% success Use Starlette's path converter for int 
    @app.route('/items/{item_id:int}')
async def get_item(item_id: int):
    ...

Dead Ends

Common approaches that don't work:

  1. Using str() on the parameter 80% fail

    Doesn't convert to int; keeps it as string.

  2. Ignoring the type and using the string directly 70% fail

    May cause errors in logic expecting an integer.
