Question

我正在进行功能测试，我收到了错误

InvalidArgumentException：当前节点列表为空

这是我的代码

我认为这是错误的：

$ form = $ submitButton-＆gt; form（$ requestContent）;

请注意，$ requestContent值来自隐藏的输入类型，它们都在form标记内。

Answer 1

您必须将按钮的文字提供给$crawler->selectButton()。

// For a given HTML button:
// <input type="button" value="Upload File" />
// or
// <button type="button">Upload File</button>

$crawler->selectButton("Upload File");

旁注，您的正则表达式'/\/nextPage'无效。您需要添加结束/ - ＆gt; '/\/nextPage/' // This will match the exact string: "/nextPage"

Answer 2

您还没有发布HTML，所以现在我假设你的HTML如下：

$submitButton = $crawler->selectButton('Submit');

改变

GetWorkItems "Agile2015Starain" "https://[your vsts name].visualstudio.com"

因为selectButton（）接受按钮值而不是id或name。

确保这对您有所帮助。
