HTMLUnit，如何在不单击提交按钮的情况下发布表单? [英] HtmlUnit, how to post form without clicking submit button?

问题描述

我知道在HtmlUnit中我可以fireEvent在表单上提交，它将被发布.但是，如果我禁用了javascript并想使用一些内置函数发布表单怎么办?

I know that in HtmlUnit i can fireEvent submit on form and it will be posted. But what If I disabled javascript and would like to post a form using some built in function?

我已经检查了Javadoc，但没有找到任何方法来执行此操作.奇怪的是，HtmlForm中没有这样的功能...

I've checked the javadoc and haven't found any way to do this. It is strange that there is no such function in HtmlForm...

我阅读了htmlunit页面上的javadoc和教程，并且知道可以使用getInputByName()并单击它.有时有些表格没有提交类型按钮 甚至有这样的按钮，但没有名称属性.

I read the javadoc and tutorial on htmlunit page and I Know that i can use getInputByName() and click it. BuT sometimes there are forms that don't have submit type button or even there is such button but without name attribute.

在这种情况下我正在寻求帮助，这就是为什么我使用fireEvent但它并不总是有效的原因.

I am asking for help in such situation, this is why i am using fireEvent but it does not always work.

推荐答案

您可以使用临时"提交按钮:

You can use a 'temporary' submit button:

WebClient client = new WebClient();
HtmlPage page = client.getPage("http://stackoverflow.com");

// create a submit button - it doesn't work with 'input'
HtmlElement button = page.createElement("button");
button.setAttribute("type", "submit");

// append the button to the form
HtmlElement form = ...;
form.appendChild(button);

// submit the form
page = button.click();
