涉及登录，所以发送http请求时要附带上登录后的cookie请求头，具体可以参考下面的，cookie头需要用浏览器开发工具获取

vb6发送带cookie的get请求_wmlongshort的博客-CSDN博客 Private Function HttpGet(ByVal URL As String, ByVal Cookie As String) As String Dim HTTP As Object Set HTTP = CreateObject("Msxml2.ServerXMLHTTP.6.0") HTTP.open "GET", URL, False ... https://blog.csdn.net/wmlongshort/article/details/103615213

要自动化，可以找到登录接口，直接post账号密码到接口获取登录后的cookie，然后下载的时候附带上获取到的身份cookie
