Question

我想从在线表单下载PDF文件。我用提琴手找出标题和帖子字段。但是，我无法使用Invoke-webrequest从Firefox获得与Powershell匹配的标题。

原始请求

POWERSHELL

我把它作为 $f = invoke-webrequest -uri $url -UserAgent $useragent -method Post -Body $param

如何让Powershell的请求与Firefox发送的一致？

Answer 1

.NET的HTTPWebRequest对象具有Accept和Referer标题的单独属性;您必须手动设置这些属性，而不是尝试直接添加标题。

（这些标题限制部分出于安全目的;部分信任代码无法设置属性。）

使用Powershell Invoke-WebRequest时设置所有标头
