Download files from website
Do you need to download files from the web but hate repeatedly clicking links? If your job involves downloading files from the web regularly, you will probably want to automate the task. Why not use PowerShell to download files? Windows PowerShell and PowerShell comes with file-download capabilities. Using PowerShell to download files is a matter of knowing which cmdlets and.
Download files from website classes to use and how to use them. Since this is a learning-by-doing article, there are some prerequisites to ensure that you can follow the examples. Below are the basic requirements. There are four methods to use PowerShell to download files that do not depend on third-party tools. These are:. Whichever one of these four methods you use, the logic and components to make them work are the same. If required by the webserver, you need to enter the credentials as well.
The next sections show each of these four methods, download files from website. The first method in PowerShell to download files is by using the Invoke-WebRequest cmdlet. Perhaps the most used cmdlet in this article, Invoke-WebRequestcan download HTTP, HTTPS, and FTP links.
Whether the source location requires users to log in, the Invoke-WebRequest cmdlet can handle requests with credentials as well. To download a file, the syntax below shows the minimum parameters required to achieve the desired outcome. For example, the code below downloads a file with the name 10MB. zip from a website. You may copy the code below and paste it into your PowerShell session to test.
The demonstration below shows the expected result after running the code above in PowerShell. As you can see, the file download was successful. How about if the source requires authentication before allowing access? For example, the code below downloads a file from a private website where users must log in.
If authentication is required, you should add a credential to the request using the -Credential parameter.
As you can see, the Get-Credential cmdlet prompted a PowerShell credential request. This time, using the credential with Invoke-WebRequest resulted in a successful download. Related: Using the PowerShell Get-Credential Cmdlet and all things credentials. A crucial download files from website to remember when using Invoke-WebRequest in Windows PowerShell is that, download files from website, by default, this cmdlet uses the Internet Explorer engine to parse data.
The error below may happen when using Invoke-WebRequest on computers without the Internet Explorer in it. Specify the UseBasicParsing parameter and try again. Starting with PowerShell Core 6. As such, the -UseBasicParsing parameter is no longer necessary. The Invoke-RestMethod cmdlet is more about sending an HTTP or HTTPS request to a RESTful web service.
This cmdlet is more suited for requests that interact with REST APIs such as Microsoft Graph API. When it comes to downloading files straight from the web, Invoke-RestMethod is an excellent contender.
Do not be deceived into thinking otherwise. There is not much difference between using Invoke-RestMethod and Invoke-WebRequest when used for downloading files from a direct web link. To download a file using Invoke-RestMethoduse the syntax below. If the source requires authentication, you can pass the credentials using the -Credential parameter. Also, since the file link is an HTTP source and not HTTPS, it means that you are sending an unencrypted authentication.
Typically, you should avoid using HTTP sources for security. But if you must use an HTTP source, you need to add the -AllowUnencryptedAuthentication switch to your command. Start-BitsTransfer is designed specifically for transferring files between client and server computers.
This PowerShell cmdlet is dependent on the Background Intelligent Transfer Service BITS that is native to the Windows operating system. Because Start-BitsTransfer requires BITS to work means that this cmdlet is not available on non-Windows computers.
On the flipside, Start-BitsTransfer enjoys the benefits of BITS itself. Some of these benefits are:. The fundamental way to use Start-BitsTransfer in PowerShell to download a file is to specify a source and destination. Suppose the destination is not specified, Start-BitsTransfer downloads and saves the file to the current working directory.
For downloads that require authentication, Start-BitsTransfer has a -Credential parameter that accepts a PSCredential object. Name the file filelist. The first column should contain the link to the source, while the second column must contain the destination path. The file contents would like the one below. Related: Managing CSV Files in PowerShell with Import-Csv. Once the CSV file is ready, use the command below download files from website begin the file download.
The command imports the CSV file using Import-Csv and passes the contents to Start-BitsTransfer. Refer to the demo below to see how the code above works, download files from website. As you can see, the download starts, and you see the download progress.
The PowerShell prompt is not available during the download process. Suppose you want to start the download process as a background job. To do so, you only have to add the -Asynchronous switch at the end of the Start-BitsTransfer command.
Initially, download files from website, the state of each job would show c onnecting. To check the download job status, use the Get-BitsTransfer cmdlet.
PowerShell is based on. NET, and its nature makes it capable of leveraging the power of. NET itself. NET class you can use in PowerShell to download files; WebClient and HttpClient. If you want to know more about these two.
HttpClient vs. In the next section, you will learn how to use WebClient and HttpClient in PowerShell to download files from the web.
To use the WebClient class, you need to initiate an object as a System. WebClient object. Then, using the DownloadFile method starts the download of the file from the source.

However, download files from website, the PowerShell prompt will be locked until the download is complete.
If the source requires authentication to allow the file download, you can use the code below. Instead, download files from website the System. HttpClient class. It appears that the WebClient class is obsolete, and the new class that Microsoft is endorsing is the HttpClient class.
The next section talks about using the HttpClient class in PowerShell to download files from the web, download files from website. Like the WebClient class, you need to create first the System. Refer download files from website the comments above each line to know what each line of code does. In situations where downloading a file requires authentication, you need to add the credential to the HttpClient object.
To include a credential to the file download request, create a new System. HttpClientHandler object to store the credentials, download files from website. You can copy the code below and run it in PowerShell to test. Or you can also run it as a PowerShell script, download files from website. In this example, the code is saved as download-file.
At the start, the directory only has the script file in it. Then, the script proceeds to download the file. After downloading the file, you can see that the new file is now inside the destination directory. Windows PowerShell and PowerShell Core come with built-in capabilities to download files. Whether downloading password protected sources, download files from website or multiple files — a PowerShell way is available to you.
The file download methods covered in this article works on both Windows PowerShell and PowerShell Core. This means that these methods apply to both Windows and Non-Windows systems, with the exclusion of Start-BitsTransfer. And since PowerShell is more than a command prompt, you can translate what you learned into scripts. For you, that would mean an opportunity for automation.
