在 url 中為 app.route 傳遞 2 個參數（python 與 flask ）

Question

嘗試傳遞兩個參數，但似乎我在這里遺漏了一些語法，有人可以幫我嗎？

@app.route('/BotMetrics/<int:fromdate>/<int:todate>')
def user(fromdate, todate):
     print("connecting")
     con = Get_hdb()
     cursor1 = con.cursor(pymysql.cursors.DictCursor)
     cursor1.execute("select * from order_details where date between '%s' and '%s'",(fromdate,todate,))
     row = cursor1.fetchall()
     resp = jsonify(row)
     resp.status_code = 200
     return resp

試圖訪問URL，這里我想在URL中傳遞兩個參數FromDate和ToDate，

將代碼更新到下面並且它有效

@app.route('/BotMetrics/<fromdate>/<todate>')
def user(fromdate=None, todate=None):
     print("connecting")
     con = Get_hdb()
     cursor1 = con.cursor(pymysql.cursors.DictCursor)
     cursor1.execute("select * from order_details where date between %s and %s",(fromdate,todate,))
     row = cursor1.fetchall()
     resp = jsonify(row)
     resp.status_code = 200
     return resp
