Invoke

Invoke is a social network for the gaming community. It has one simple goal–to offer gamers an experience like no other. Rather than focusing on video game content, Invoke lets players interact with each other in new and exciting ways through its games and challenges

In computer programming, the “invoke vs evoke” are two different ways to call a function. The difference between them is that an invoke will cause the function to be executed immediately whereas an “evoke” will return a value and wait for it to be called later.

Have you ever wished to use the command line to surf the web? Yea. Neither do I. Have you ever required to extract data from a webpage, monitor a website, or automate the submission of data? I have, and I do it using Invoke-Webrequest!

The Invoke-WebRequest PowerShell cmdlet is the web’s equivalent of a Swiss army knife. This cmdlet may transmit any HTTP verb to a web service, as well as HTTP arguments, HTTP headers, and other standard features. If you need to execute any type of web automation, you’ll want to educate yourself with Invoke-WebRequest and its sibling, Invite-RestMethod in PowerShell.

Using Invoke-WebRequest to Download Files

Invoke-WebRequest may also be used to download files from the internet, and it’s quite simple! By targeting Invoke-WebRequest to a file’s URI and using the OutFile option to inform the cmdlet to save the file to local drive, we may download files.

I’m downloading the SysInternals Handle program, for example, and then expanding the zip file after it’s downloaded. It’s really that simple!

‘https://download.sysinternals.com/files/Handle.zip’ Invoke-WebRequest -Uri ‘ C:handle.zi -OutFile C:handle.zip -Path Expand-Archive

Working with Sessions and Submitting a Form

Invoke-WebRequest may also be used to fill out forms. However, we often need to deal with web sessions to do this. Because HTTP is a stateless protocol, your browser (in this instance, PowerShell) has to be able to generate a session that can be used to monitor things like cookies. A login/password form is a frequent kind of form, so let’s try it out on a fictitious website!

Assume our fictitious login form is located at http://somewebsite.com. To download the HTML structure and start a session, we’d need to use Invoke-WebRequest first.

$response = Invoke-WebRequest -Uri ‘http://somewebsite.com’ -SessionVariable rb $response = Invoke-WebRequest -Uri ‘http://somewebsite.com’ -SessionVariable rb

After that, we’ll have a Forms property in the response that we can fill with a login and password. In this scenario, the username is represented by the field user, and the password is represented by the field password. This will be determined by the website.

$response = $form Forms[0] $form. [“user”] = “username” Fields[“user”] = “username” $form. “password” in Fields[“password”] = “password” in Fields[“password”] = “password” in

After the form has been filled out, we can use Invoke-WebRequest again, but this time we’ll re-use the session we just generated and utilize the Action property on the form to automatically figure out the URI to send it to, as seen below.

Invoke-WebRequest -Uri $form $response WebSession is an action. -Method $rb POST

You should be signed in with the username and password within the $rb web session if you’ve got all of the relevant field names correct and the site isn’t doing anything crazy. If you utilize the $rb web session variable at this point, you may view different sites behind that authentication.

Short URI Resolving

Finally, another great use of Invoke-WebRequest is Short URI Resolving. Perhaps you need to know what’s behind that shortened URL but don’t want to click on it to find out! No problem. Using Invoke-WebRequest, we can read the AbsoluteUri property from the parsed response it gives us!

I’m also using the UseBasicParsing argument in the code below. By default, Invoke-WebRequest attempts to parse the HTML provided using Internet Explorer (IE). This isn’t compatible with computers that don’t have Internet Explorer. To get around this, we may utilize the UseBasicParsing argument to just weakly parse the material while still downloading it.

$Url = ‘buff.ly/2sWvPOH’; $Url = ‘buff.ly/2sWvPOH’; $Url = Invoke-WebRequest -Uri $Web -UseBasicParsing $Url $Web.BaseResponse.ResponseUri.AbsoluteUri

Summary

The PowerShell cmdlet Invoke-WebRequest is one of the most flexible cmdlets available. The Invoke-WebRequest cmdlet may do any activity that can be performed with a standard graphical browser. Take a look at this post on monitoring REST APIs for an example of how to use this cmdlet.

After that, we’ll have a Forms property in the response that we can fill with a login and password. In this scenario, the username is represented by the field user, and the password is represented by the field password. This will be determined by the website.

$response = $form Forms[0] $form. [“user”] = “username” Fields[“user”] = “username” $form. “password” in Fields[“password”] = “password” in Fields[“password”] = “password” in

After the form has been filled out, we can use Invoke-WebRequest again, but this time we’ll re-use the session we just generated and utilize the Action property on the form to automatically figure out the URI to send it to, as seen below.

Invoke-WebRequest -Uri $form $response WebSession is an action. -Method $rb POST

You should be signed in with the username and password within the $rb web session if you’ve got all of the relevant field names correct and the site isn’t doing anything crazy. If you utilize the $rb web session variable at this point, you may view different sites behind that authentication.

Short URI Resolving

Finally, another great use of Invoke-WebRequest is Short URI Resolving. Perhaps you need to know what’s behind that shortened URL but don’t want to click on it to find out! No problem. Using Invoke-WebRequest, we can read the AbsoluteUri property from the parsed response it gives us!

I’m also using the UseBasicParsing argument in the code below. By default, Invoke-WebRequest attempts to parse the HTML provided using Internet Explorer (IE). This isn’t compatible with computers that don’t have Internet Explorer. To get around this, we may utilize the UseBasicParsing argument to just weakly parse the material while still downloading it.

$Url = ‘buff.ly/2sWvPOH’; $Url = ‘buff.ly/2sWvPOH’; $Url = Invoke-WebRequest -Uri $Web -UseBasicParsing $Url $Web.BaseResponse.ResponseUri.AbsoluteUri

Summary

The PowerShell cmdlet Invoke-WebRequest is one of the most flexible cmdlets available. The Invoke-WebRequest cmdlet may do any activity that can be performed with a standard graphical browser. Take a look at this post on monitoring REST APIs for an example of how to use this cmdlet.

.class -eq ‘ng-binding’ $result.Links

Once I know this, I can go ahead and discover all of those elements, returning just the innerHTML attribute, and voilà!

where

Have you ever wished to use the command line to surf the web? Yea. Neither do I. Have you ever required to extract data from a webpage, monitor a website, or automate the submission of data? I have, and I do it using Invoke-Webrequest!

The Invoke-WebRequest PowerShell cmdlet is the web’s equivalent of a Swiss army knife. This cmdlet may transmit any HTTP verb to a web service, as well as HTTP arguments, HTTP headers, and other standard features. If you need to execute any type of web automation, you’ll want to educate yourself with Invoke-WebRequest and its sibling, Invite-RestMethod in PowerShell.

Microsoft provides the Invoke-WebRequest cmdlet. PowerShell. Windows PowerShell and PowerShell Core provide a utility module. This cmdlet has been available with PowerShell since version 3, and it is incredibly powerful while being simple to use.

PowerShell’s Invoke-WebRequest command enables a developer to interact with websites, online services, and REST APIs in a variety of ways.

Usage Basics

The Invoke-WebRequest cmdlet delivers an HTTP request method to an endpoint, such as a URI or URL, at its most basic level. All of the standard request methods are supported by the cmdlet.

The GET approach is by far the most popular. This function retrieves data from a website or by accessing a REST API. The Technique argument is used to specify the method. We’ll additionally require a URI since we’ll need an endpoint to query. To make things simple, I’ll choose any website. I’ll go with techsnips.io to shamelessly advertise TechSnips.

Assume I want a list of all the most recently released videos, like seen below.

An example of a website

Run Invoke-WebRequest -Uri ‘https://techsnips.io’ -Method Obtain to get an HTML representation of this page. Invoke-WebRequest gets the complete web page and delivers an output with different parsed information surrounding the page’s components when I do this.

response from Invoke-WebRequest

I’ll have to do some research to find the videos. When I examine the links property, I notice that all of the video links have the ng-binding class, as shown below.

$result.Links | where {$_.class -eq ‘ng-binding’}

Once I know this, I can go ahead and discover all of those elements, returning just the innerHTML attribute, and voilà!

$result.links | where {$_.class -eq ‘ng-binding’} | Select-Object innerHtml

Using Invoke-WebRequest to Download Files

Invoke-WebRequest may also be used to download files from the internet, and it’s quite simple! By targeting Invoke-WebRequest to a file’s URI and using the OutFile option to inform the cmdlet to save the file to local drive, we may download files.

I’m downloading the SysInternals Handle program, for example, and then expanding the zip file after it’s downloaded. It’s really that simple!

‘https://download.sysinternals.com/files/Handle.zip’ Invoke-WebRequest -Uri ‘ C:handle.zi -OutFile C:handle.zip -Path Expand-Archive

Working with Sessions and Submitting a Form

Invoke-WebRequest may also be used to fill out forms. However, we often need to deal with web sessions to do this. Because HTTP is a stateless protocol, your browser (in this instance, PowerShell) has to be able to generate a session that can be used to monitor things like cookies. A login/password form is a frequent kind of form, so let’s try it out on a fictitious website!

Assume our fictitious login form is located at http://somewebsite.com. To download the HTML structure and start a session, we’d need to use Invoke-WebRequest first.

$response = Invoke-WebRequest -Uri ‘http://somewebsite.com’ -SessionVariable rb $response = Invoke-WebRequest -Uri ‘http://somewebsite.com’ -SessionVariable rb

After that, we’ll have a Forms property in the response that we can fill with a login and password. In this scenario, the username is represented by the field user, and the password is represented by the field password. This will be determined by the website.

$response = $form Forms[0] $form. [“user”] = “username” Fields[“user”] = “username” $form. “password” in Fields[“password”] = “password” in Fields[“password”] = “password” in

After the form has been filled out, we can use Invoke-WebRequest again, but this time we’ll re-use the session we just generated and utilize the Action property on the form to automatically figure out the URI to send it to, as seen below.

Invoke-WebRequest -Uri $form $response WebSession is an action. -Method $rb POST
