關(guān)于Pyqt5實現(xiàn)自動化操作的問題

在李毅大神的PyQt5 內(nèi)嵌瀏覽器注入 Javascript 腳本實現(xiàn)自動化操作的幫助貼下，我現(xiàn)在已經(jīng)完成了對廉價航空公司的自動化操作，但是現(xiàn)在我遇到了幾個問題：

1. 我在完成訂單后，比如進入到最后的頁面了，判斷出網(wǎng)頁url是/BookFlight/Wait之后，我該如何傳遞給我的應(yīng)用讓它自動關(guān)閉？或者中途有異常（比如彈出驗證碼的時候）如何捕獲異常
2. 如何給Pyqt5的內(nèi)嵌瀏覽器掛代理IP
3. 我現(xiàn)在在封裝代碼至flask的時候，JS里面的參數(shù)該如何傳遞，當(dāng)我使用format或者%S時都會出現(xiàn)錯誤，因為js代碼里面有"{}"以及"[]"

希望我的疑惑能得到解答

當(dāng)前Python代碼如下：
