我将如何提取底部的网址，这只是返回的实际请求正文中的一个示例，它包含多个网址。

Answer 1

您可以通过正则表达式搜索并找到与之匹配的格式:

const urlRegex =/https?:\/\/(www\.)?[-a-zA-Z0-9@:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()@:%_\+.~#?&//=]*)/ig

// responseBodyText from the response you get
const matchedUrls = responseBodyText.match(urlRegex);

const extractedUrls = matchedUrls ? matchedUrls : []
// it should prints the all the urls on the response if there is any or empty array if not
