TimeoutError：[WinError 10060] 連接嘗試失敗：除了塊也不執行

Question

在我的程序中，我嘗試並排除像這樣的塊

try:
    if exitCritera(ceLiveprc,peLiveprc,ceEntry,peEntry):
        closeAllOpenAndPendingTrades(cTok,pTok,ceEntry,peEntry)
except(TimeoutError) as e:
    print("Timeout error occured re-trying...:{}".format(datetime.now()))
    time.sleep(1)
    if exitCritera(ceLiveprc,peLiveprc,ceEntry,peEntry):
        closeAllOpenAndPendingTrades(cTok,pTok,ceEntry,peEntry)

exitCriteria function 檢查一些數據，然后調用 closeAllOpenAndPendingTrades() 並且在 closeAllOpenAndPendingTrades() 中有與服務器的聯系。

我注意到我在打球。

所以我添加了 except 塊。 但是 except 塊根本不執行。 一旦發生超時錯誤，我可以做些什么來重試？

[WinError 10060] 是 Windows 套接字錯誤。 嘗試將其捕獲為 OSError，這在非常相似的情況下對我有用。

將您的代碼更改為以下內容：

try:
    if exitCritera(ceLiveprc,peLiveprc,ceEntry,peEntry):
        closeAllOpenAndPendingTrades(cTok,pTok,ceEntry,peEntry)
except OSError as e:
    print(e)
    print("Timeout error occured re-trying...:{}".format(datetime.now()))
    time.sleep(1)
    if exitCritera(ceLiveprc,peLiveprc,ceEntry,peEntry):
        closeAllOpenAndPendingTrades(cTok,pTok,ceEntry,peEntry)
