如何使Powershell的请求与Firefox发送的请求相匹配?.NET的HTTPWebRequest对象对
Accept
和Referer
头具有单独的属性;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)。您的$url不应该设置为
http://somesight/SPLeam/EAMDisplayReportWithParamValues.asp
为了匹配工作示例?此外,请尝试将表单正文放入哈希表中以获得正确的HTML编码,例如,-body@{Text0='12/1/2013';…;cmdSaveParameters='Run+Report'}
正文位于哈希表中,与您描述的一样。URL将转到标头中描述的referer URL。我想使用原始URL,但无法在标题选项中添加referer。我犯了一个错误。也无法将Accept添加到标头。另一种单独添加它们的方法?如何手动设置它们并将它们合并到invoke webrequest?哪个版本的Powershell?请参阅,例如,这不适用于Invoke WebRequest。PowerShell不会公开HttpWebRequest的那些属性。相反,您需要设置Headers参数,该参数采用IDictionary参数。
