POST 请求：
①输入Well API号
我检查了做出您提到的选择的网页。我使用fiddler 检查了网络流量，并注意到初始请求在您提交 API 编号时由POST request 处理。
② POST 请求：
POST 正文有以下参数：
p_apinum 是键，关联的值是原始 Well API 编号。
使用此信息，我直接制定了 POST 请求，从而避免了您的第一个目标网页。
③点击超链接：
接下来，我注意到你要按下的元素：
查看关联的 HTML，它有一个关联的相对超链接：
我使用辅助函数来解析页面 HTML 以获取此相对链接并构造绝对路径：GetNextURL(page.body.innerHTML)。
④ 提出新请求：
我重新使用我的 HTTPRequest 函数 GetPage 发送第二个请求，主体为空，并从通过 page.getElementsByTagName("table") 返回的 HTML 文档中获取所有表格。
⑤ 将表格写入 Excel 工作表：
我使用辅助函数 AddHeaders 循环页面上的所有表格以写出表格标题，并使用 WriteTables 将当前表格写入工作表。
