您如何在回圈上運行通過或失敗測驗、識別失敗并繼續通過失敗的嘗試？

我有一個程式回圈通過用作 URL 的 IP 地址檔案。它登錄、進行更改、保存和注銷。我需要執行通過或失敗測驗以查看哪些 URL 沒有完成回圈。此外，我還需要回圈繼續傳遞失敗，同時將它們寫入檔案，這樣我就可以看到哪些沒有通過。現在，程式將回圈直到遇到錯誤的 URL，然后拋出 ERR_CONNECTION_TIMED_OUT。任何幫助將不勝感激，因為我是編程和 SO 的新手。

uj5u.com熱心網友回復：

您可以做的是為您正在處理的每一行添加一個 try-catch。例如，您可以按如下方式重寫回圈：

        FileWriter writer = new FileWriter("path");
        BufferedWriter bwr = (new BufferedWriter(writer));
        while((line = reader.readLine()) != null) {
            data ="http://" line;
            System.out.println(data);
            try {
                doActionLine(data); 
                //add test passed               
                bwr.write(data   "- Test Passed\n");
                bwr.write("\n");
            } catch (Exception e) {
                //add test failed         
                bwr.write(data   "- Test Failed\n");
                bwr.write("\n");
            }
            
        }

如您所見， doActionLine 函式已經封裝了檢查：

private void doActionLine(String data) throws InterruptedException {
    //open browser
    driver.get(data);
    driver.switchTo().frame(driver.findElement(By.name("bodyf")));
    Thread.sleep(2000);
    driver.findElement(By.name("username")).sendKeys("user");
    Thread.sleep(2000);
    driver.findElement(By.name("password")).sendKeys("pass");
    driver.findElement(By.xpath("/html/body/form/span/table/tbody/tr[3]/td/p/input")).click();
    //find password
    driver.switchTo().frame(driver.findElement(By.name("left")));
    driver.findElement(By.xpath("//*[@id=\"4050000\"]/a")).click();
    driver.findElement(By.xpath("//*[@id=\"4050000\"]/table/tbody/tr[3]/td[2]/a")).click();
    //change password
    driver.switchTo().parentFrame();
    driver.switchTo().frame(1);
    Thread.sleep(2000);
    driver.findElement(By.xpath("/html/body/form/p[1]/table/tbody/tr[2]/td[2]/input")).sendKeys("newpass");
    Thread.sleep(2000);
    driver.findElement(By.xpath("/html/body/form/p[1]/table/tbody/tr[3]/td[2]/input")).sendKeys("newpass");
    Thread.sleep(2000);
    driver.findElement(By.xpath("/html/body/form/p[2]/input[2]")).click();
    //save and logout
    Thread.sleep(3000);
    driver.switchTo().alert().accept();
    driver.switchTo().parentFrame();
    driver.switchTo().frame(driver.findElement(By.name("left")));
    driver.findElement(By.id("sysLogout")).click();
    Thread.sleep(3000);
    driver.switchTo().alert().accept();
}

我希望這對你有幫助。
