推荐答案

Invoke-WebRequest带有一个参数，用于将其结果存储在文件中:-OutFile

Invoke-WebRequest comes with a parameter to store its result in a file: -OutFile

Invoke-WebRequest URL -OutFile c:\file.ext

如果需要授权，则可以发送如下请求:

If you need authorization before you can send a request like this:

Invoke-WebRequest URL /* whatever is neccesary to login */ -SessionVariable MySession
Invoke-WebRequest URL -WebSession $MySession

要确定登录发生的表单的布局，可以使用Invoke-WebRequests返回对象.它将收集有关HTML上的表单和字段的信息(可能仅适用于Windows).登录里程可能会因两因素身份验证"是否处于活动状态而有所不同.可能您可以创建一些不需要Auth的文件的秘密链接，或者Google可能允许您创建某种形式的私有访问令牌，可以将其随请求发送给Authorization-Header.

To determine the layout of the form where the login happens, you can use Invoke-WebRequests return object. It'll collect information about forms and fields on the HTML (might be Windows only). Mileage of logging in may vary with things like Two-Factor-Auth active or not. Probably you can create some secret link to your file which does not need Auth or possibly google allows you to create a private access token of some sort, which can be send aus Authorization-Header alongside your request.
