Get web file

The Body parameter may also accept a System. MultipartFormDataContent object. This feature was added in PowerShell 6. Specifies the client certificate that's used for a secure web request. Enter a variable that contains a certificate or a command or expression that gets the certificate. If the certificate isn't valid or doesn't have sufficient authority, the command fails. Specifies the digital public key certificate X of a user account that has permission to send the request.

Enter the certificate thumbprint of the certificate. Certificates are used in client certificate-based authentication. They can be mapped only to local user accounts; they don't work with domain accounts. Otherwise, the content type isn't specified in the call. Specifies a user account that has permission to send the request.

The default is the current user. Credential can be used alone or in conjunction with certain Authentication parameter options.

When used alone, it only supplies credentials to the remote server if the remote server sends an authentication challenge request. When used with Authentication options, the credentials are explicitly sent. Specifies a custom method used for the web request. This can be used if the Request Method required by the endpoint isn't an available option on the Method. Method and CustomMethod can't be used together. By default, KeepAlive is True. KeepAlive establishes a persistent connection to the server to facilitate subsequent requests.

Form may not be used with Body. If ContentType is used, it's ignored. The keys of the dictionary are used as the form field names. By default, form values are converted to string values. If the value is a System. FileInfo object, then the binary file contents are submitted. The name of the file is submitted as the filename property. Get-Item can be used to simplify supplying the System. FileInfo object. If the value is a collection type, such Arrays or Lists, the for field are submitted multiple times.

The values of the list are treated as strings by default. Nested collections aren't supported. In the above example the tags field are supplied three times in the form, once for each of Vacation , Italy , and The pictures field is also submitted once for each file in the Italy folder. The binary contents of the files in that folder are submitted as the values. To set UserAgent headers, use the UserAgent parameter. You can't use this parameter to specify User-Agent or cookie headers. Gets the content of the web request from a file.

Enter a path and file name. If you omit the path, the default is the current location. The default value is 5. A value of 0 zero prevents all redirection. Specifies how many times PowerShell retries a connection when a failure code between and , inclusive or is received. Also see RetryIntervalSec parameter for specifying number of retries.

Indicates that the cmdlet shouldn't use a proxy to reach the destination. When you need to bypass the proxy configured in the environment, use this switch. Specifies the output file for which this cmdlet saves the response body. The name is treated as a literal path. Names that contain brackets [] must be enclosed in single quotes '.

By default, Invoke-WebRequest returns the results to the pipeline. To send the results to a file and to the pipeline, use the Passthru parameter. Indicates that the cmdlet returns the results, in addition to writing them to a file. This parameter is valid only when the OutFile parameter is also used in the command. Indicates the cmdlet should preserve the Authorization header, when present, across redirections.

By default, the cmdlet strips the Authorization header before redirecting. Specifying this parameter disables this logic for cases where the header needs to be sent to the redirection location. Specifies a proxy server for the request, rather than connecting directly to the internet resource. Enter the URI of a network proxy server.

Specifies a user account that has permission to use the proxy server that is specified by the Proxy parameter. This parameter is valid only when the Proxy parameter is also used in the command. Indicates that the cmdlet uses the credentials of the current user to access the proxy server that is specified by the Proxy parameter.

Performs a best effort attempt to resume downloading a partial file. Resume requires OutFile. Resume only operates on the size of the local file and remote file and performs no other validation that the local file and the remote file are the same. If the local file size is smaller than the remote file size, then the cmdlet attempts to resume downloading the file and append the remaining bytes to the end of the file. If the local file size is the same as the remote file size, then no action is taken and the cmdlet assumes the download already complete.

If the local file size is larger than the remote file size, then the local file is overwritten and the entire remote file is re-downloaded. This behavior is the same as using OutFile without Resume. When I put this content through a foreach loop it dumps every line at once. If I save it to a file then I can use System.

File::ReadLines to steps through line by line but that only works if I download the file. How can I accomplish this without downloading the file? You can't parse text files with Invoke-WebRequest. If the text file is unstructured you can parse it with regex. More information about using regex in PowerShell can be found here and here.

I am trying to download files from a site, sadly they are be generated to include the Epoch Unix timestamp in the file name. Now as I am unable to replace the Epoch Unix timestamp portion of the file name with a wild card, I was wondering if there was a way to do the download based on the date modified field of the file?

Thanks for this. I plan to use this along with task scheduler to download a fresh file every week. However, the new file overwrites the older one. Is there a way to preserve the older file as well? Ken - You should be able to relatively easily - however, you'd have to download it first, since you can't get the file properties until you download it.

You could download it to a temp location, grab the LastWriteTime stamp and parse it to create your new name. Sumit - You have a similar situation. You'll also need to manage the old copies so you don't fill up your disk.

Basically at the moment I have a problem and have to open powershell in the directory where the powershell script is, or navigate to the directory. From there I then have to execute my script. I want to just be able to execute script from anywhere on the shell without messing about with specifying the path to the tool, is than even possible? Marta, you can append the PATH environment variable. Having them in your path doesn't necessarily do much for you. If you just dot source them from your profile, then you can easily call your functions from anywhere..

David, that works if you just have a few tiny scripts. However, in general you will want to organize your scripts in folders. Why do you think that working with the path variable won't work?

Hi, i made some progress, the script can be used from Computer Client like Win10, and he dont need to import Active Directory modules, also dont need to enter config.

Brandon Lee wrote a new post, Redirect user profile folders documents, pictures, etc. For a long time, roaming profiles and folder redirection were the standard means under Windows for making user files available on different devices. Now that more and more users work on the road or at home rather than in the office, this technique is becoming increasingly obsolete.

An alternative to such environments is to redirect profile folders to OneDrive. Paolo Maffezzoli posted an update 14 hours, 21 minutes ago. Paolo Maffezzoli posted an update 14 hours, 22 minutes ago.
