这是我的工作项目，所以我不能像我想的那样具体

我正在设计的java应用程序应该执行以下操作：

  • 填充网页的表单
  • 点击提交
  • 打开显示成功/失败的新页面
  • 在5秒钟内，新页面会根据成功/失败自动重定向到另一个页面
  • 因此，数据库将更新
（这些网页已经存在，并且按照我在这里描述的那样进行设置，我的应用程序应该会自动处理它们）

我尝试使用HtmlUnit来处理页面、填写表单和单击按钮

然而，如果可能的话，我希望避免一些例外情况

1） 当我这样配置web客户端时：

    wc = new WebClient();
    wc.setJavaScriptEnabled(false);
代码执行它应该执行的操作，但引发以下异常：

代码正常工作，数据库已成功更新，但在最后一次重定向时失败，无法打开最后一页：(

2） 当我将web客户端配置为这样时：

    wc.setThrowExceptionOnFailingStatusCode(false);
我遇到以下异常，程序无法运行：

代码在此点之后退出，并且数据库没有更改

我想要的是完全消除这些异常。如何配置WebClient使其不再像这样胡闹？

你的付款成功了
您将很快被重定向回原始站点。或者，只需单击下面的链接。
（为了保护雇主的隐私，我已经更改了财产名称）

我解决了这个问题：）

刷新导致的页面太大，无法放入页面对象

我将重定向url更改为：

现在它可以工作了。

更新-提交按钮不是，而是一个图像。我使用以下代码单击它：page=（HtmlPage）（（ClickableElement）form.getFirstByXPath（nameValues.get（“submitXPath”））。单击（）；我认为关闭webclient中的JavaScript是阻止这种重定向的原因。但是如果我不打开它，我会得到一个巨大的异常，它太大了，无法放入控制台。
