web3.py transactionReceipt 中的欄位為空

我獲取了一個區塊的交易收據，並對某些欄位有一些疑問。如果交易收據顯示“to”欄位為空，“contractAddress”欄位中顯示地址，是否表示指定的合約已創建？

此外，如果在contractAddress 下沒有指定地址並且顯示一個空的日誌欄位怎麼辦。這兩種情況說明了什麼？如果日誌數組為空但我們確實有輸入數據，那麼這兩者之間的數據類型有什麼區別？據我了解日誌

$$ $$包含事件資訊，但輸入數據包含有關所呼叫方法的資訊。我對嗎？

如果交易回執顯示該to欄位為空且該contractAddress欄位中有地址，是否表示指定的合約已創建？

是的，這意味著在contractAddress欄位中指定的地址部署了合約。而恰恰相反意味著交易被發送到已經部署在to欄位中指定地址的合約。

另外，如果沒有指定地址contractAddress並顯示一個空logs欄位怎麼辦？

如上所述，交易被發送到已經部署的合約。並且該logs欄位為空的事實意味著在事務期間沒有發出任何事件。
