Powershell Invoke-WebRequest，「Form」「form」在哪裏？

Question

我一直在處理Powershell約一個月。我對編碼和Powershell很新穎。

我GOOGLE瞭如何使用調用-的WebRequest

https://technet.microsoft.com/en-us/library/hh849901.aspx

或

https://gist.github.com/haraldfianbakken/32d5ac624c842a766df3

我曾嘗試同樣的事情有兩個鏈接。

所以我做了一個腳本。

$r = Invoke-WebRequest "https://idp.appery.io/idp/" -SessionVariable ws; 

$r|Get-Member 

它呼應了

Equals   Method  bool Equals(System.Object obj)          
GetHashCode  Method  int GetHashCode()             
GetType   Method  type GetType()              
ToString   Method  string ToString()             
BaseResponse  Property System.Net.WebResponse BaseResponse {get;set;}      
Content   Property byte[] Content {get;}            
Headers   Property System.Collections.Generic.Dictionary[string,string] Headers {get;} 
RawContent  Property string RawContent {get;}           
RawContentLength Property long RawContentLength {get;}          
RawContentStream Property System.IO.MemoryStream RawContentStream {get;}      
StatusCode  Property int StatusCode {get;}            
StatusDescription Property string StatusDescription {get;} 

根據這些網站，它應該有一個表格。

這樣我就可以去這樣

$

r=Invoke-WebRequest http://www.facebook.com/login.php -SessionVariable fb 

# Use the session variable that you created in Example 1. Output displays values for Headers, Cookies, Credentials, etc. 

$fb 

# Gets the first form in the Forms property of the HTTP response object in the $r variable, and saves it in the $form variable. 

$form = $r.Forms[0] 

# Pipes the form properties that are stored in the $forms variable into the Format-List cmdlet, to display those properties in a list. 

$form | Format-List 

# Displays the keys and values in the hash table (dictionary) object in the Fields property of the form. 

$form.fields 

# The next two commands populate the values of the "email" and "pass" keys of the hash table in the Fields property of the form. Of course, you can replace the email and password with values that you want to use. 

$form.Fields["email"] = "User01@Fabrikam.com" 
$form.Fields["pass"] = "P@ssw0rd" 

我想去確切上面的代碼相同的路徑，但是這一點，我沒有看到https://idp.appery.io/idp/，當「表」我看到網站，有一些表格可以輸入我的憑證，但是當我做了$ r | gm時，「表格」沒有顯示出來。

是否有任何原因沒有顯示？

是否有另一種方式來把我的憑據，所以我可以做兩個網站完全相同的東西？

非常感謝。

我在我的對象中獲取表單。根據文檔，你只會得到那裏的東西。

這裏是當我嘗試谷歌：

PS C:\Users\Administrator> Invoke-WebRequest -Uri google.com | gm 


    TypeName: Microsoft.PowerShell.Commands.HtmlWebResponseObject 

Name    MemberType Definition                 
----    ---------- ----------                 
Equals   Method  bool Equals(System.Object obj)            
GetHashCode  Method  int GetHashCode()               
GetType   Method  type GetType()                
ToString   Method  string ToString()               
AllElements  Property Microsoft.PowerShell.Commands.WebCmdletElementCollection AllElements {get;} 
BaseResponse  Property System.Net.WebResponse BaseResponse {get;set;}        
Content   Property string Content {get;}              
Forms    Property Microsoft.PowerShell.Commands.FormObjectCollection Forms {get;}    
Headers   Property System.Collections.Generic.Dictionary[string,string] Headers {get;}   
Images   Property Microsoft.PowerShell.Commands.WebCmdletElementCollection Images {get;}  
InputFields  Property Microsoft.PowerShell.Commands.WebCmdletElementCollection InputFields {get;} 
Links    Property Microsoft.PowerShell.Commands.WebCmdletElementCollection Links {get;}  
ParsedHtml  Property mshtml.IHTMLDocument2 ParsedHtml {get;}          
RawContent  Property string RawContent {get;}             
RawContentLength Property long RawContentLength {get;}            
RawContentStream Property System.IO.MemoryStream RawContentStream {get;}        
Scripts   Property Microsoft.PowerShell.Commands.WebCmdletElementCollection Scripts {get;}  
StatusCode  Property int StatusCode {get;}              
StatusDescription Property string StatusDescription {get;}  

當我嘗試你在談論的部位，我甚至不得到HtmlWebResponse對象返回。

在這種情況下，使用IE自動化來嘗試自動化可能是件好事。
