根因分析

路由中的多个路径参数具有相同的名称，导致歧义。

English

Multiple path parameters in a route have the same name, causing ambiguity.

generic

解决方案

  1. 95% 成功率 Rename one of the path parameters to be unique 
    @app.route('/items/{item_id}/details/{detail_id}')
async def get_detail(item_id: str, detail_id: str):
    ...
  2. 85% 成功率 Combine parameters into a single path segment 
    @app.route('/items/{item_id}')
async def get_item(item_id: str):
    ...

无效尝试

常见但无效的做法:

  1. Removing one of the parameters without adjusting the route 80% 失败

    Breaks the route logic; URL pattern becomes incorrect.

  2. Using different variable names but same path segment 90% 失败

    Starlette still sees duplicate path parameters.
