我有一個燒瓶應用程式，它以引數形式從 url 中提取 3 個值，例如 - 股票代碼、開始日期、結束日期
我面臨的問題是，當我第一次點擊 url 時，它會正確回傳我的資料，盡管當我下次嘗試它同時更改引數的值時它不起作用
URL的標準格式-127.0.0.1:5000/api?ticker=IEX&start=25-04-2022&end=25-05-2022
盡管當我說將起始值從 25-04-2022 更改為 25-03-2022 引數時，代碼回傳的值與第一個引數相同。
這是我的代碼

uj5u.com熱心網友回復：
可能是因為你快取超時為0，所以快取設定為無限時間
@cache.cached(timeout=0)
嘗試注釋掉或洗掉以下行
cache = Cache(app)
@cache.cached(timeout=0)
