Shell to download a file with HTTP, HTTPS, and FTP 4sysops. In Power. Shell, you can download a file via HTTP, HTTPS, and FTP with the Invoke Web. Request cmdlet. Michael Pietroforte is the founder and editor of 4sysops. He is a Microsoft Most Valuable Professional MVP with more than 3. IT management and system administration. Latest posts by Michael Pietroforte see allDownload with SMB If you are working in a hybrid IT environment, you often need to download or upload files from or to the cloud in your Power. Shell scripts. If you only use Windows servers that communicate through the Server Message Block SMB protocol, you can simply use the Copy Item cmdlet to copy the file from a network share. Copy Item Source serversharefile Destination C path1. Copy Item Sourceserversharefile Destination. C pathThis assumes that you have a VPN solution in place so that your cloud network virtually belongs to your intranet. Things get a bit more complicated if we are leaving the intranet and have to download from an extranet or the Internet. Download in Power. Shell 2 The next simple case is where you have to download a file from the web or from an FTP server. In Power. Shell 2, you had to use the New Object cmdlet for this purpose. Web. Client New Object System. Net. Web. Client. Web. Client. Download. Filehttps www. C pathfileWeb. ClientNew Object. System. Net. Web. ClientWeb. Client. Download. Filehttps www. C pathfileAs of Power. Shell 3, we have the Invoke Web. Request cmdlet, which is more convenient to work with. It is Power. Shells counterpart to GNU wget, a popular tool in the Linux world, which is probably the reason Microsoft decided to use its name as an alias for Invoke Web. Request. This is perhaps an understatement Invoke Web. Request is more powerful than wget because it allows you to not only download files but also parse them. But this is a topic for another post. Download with Invoke Web. Request To simply download a file through HTTP, you can use this command. Invoke Web. Request Uri http www. Out. File C pathfile1. Invoke Web. Request Urihttp www. Out. FileC pathfileIn the example, we just download the HTML page that the web server at www. Note that, if you only specify the folder without the file name, as you can do with Copy Item, Power. Shell will error Invoke Web. Request Could not find a part of the path. The shorter version for the command line is. If you omit the local path to the folder, Invoke Web. Request will just use your current folder. The Outfile parameter is always required if you want to save the file. The reason is that, by default, Invoke Web. Request sends the downloaded file to the pipeline. However, the pipeline will then not just contain the contents of the file. Instead, you will find an object with a variety of properties and methods that allow you to analyze text files. If you send a binary file through the pipeline, Power. Shell will treat it as a text file and you wont be able to use the data in the file. To only read the contents of the text file, we need to read the Content property of the object in the pipeline. Invoke Web. Request http www. Select Object Expand. Property Content Out File file1. Invoke Web. Requesthttp www. Select Object Expand. Property ContentOut FilefileThis command does the same thing as the previous one. The Expand. Property parameter ensures that the header in this case, Content wont be stored in the file. If you want to have the file in the pipeline and store it locally, you have to use Pass. Thru parameter. Invoke Web. Request http www. Out. File file Pass. Thru Select Object Expand. Property Content. Invoke Web. Requesthttp www. Out. Filefile Pass. ThruSelect Object Expand. Property Content. This command stores the web page in a file and displays the HTML code. Download and display file. Authenticating at a web server If the web server requires authentication, you have to use the Credential parameter. Invoke Web. Request Uri https www. Out. File C pathfile Credential your. User. Name1. Invoke Web. Request Uri https www. Out. File C pathfile Credential your. User. NameNote that, if you omit the Credential parameter, Power. Shell will not prompt you for a user name and password and will throw this error Invoke Web. Request Authorization Required. You have to at least pass the user name with the Credential parameter. Power. Shell will then ask for the password. If you want to avoid a dialog window in your script, you can store the credentials in a PSCredential object. Credentials Get Credential. Invoke Web. Request Uri https www. Out. File C pathfile Credential CredentialsCredentialsGet Credential. Invoke Web. Request Urihttps www. Out. FileC pathfile CredentialCredentials. You can use the Use. Default. Credentials parameter instead of the Credential parameter if you want to use the credentials of the current user. To add a little extra security, you might want to encrypt the password. Make sure to always use HTTPS instead of HTTP if you have to authenticate on a remote server. If the web server uses basic authentication, your password will be transmitted in clear text if you download via HTTP. Note that this method only works if the web server manages authentication. Nowadays, most websites use the features of a content management system CMS to authenticate users. Usually, you then have to fill out an HTML form. I will explain in one of my next posts how you can do this with Invoke Web. Request. Downloading files through FTP works analogous to HTTP. You also shouldnt use this protocol if security matters. To download multiple files securely, you had better work with SFTP or SCP. Invoke Web. Request doesnt support these protocols. However, third party Power. Shell modules exist that step into the breach. In my next post I will show you can use Invoke Web. Request to parse HTML pages and scrape content from websites.
