I need to upload files via commandline / powershell.
It works fine with
curl -F "file=#test.txt" https://api.anonfiles.com/upload
However, curl does not exist on Windows Server 2016 and I do not want to tell my clients to set it up. So I am looking for a powershell alternative to accomplish this task. I tried various solutions, but none of them worked. What I tried so far:
(1)
$postParams = #{file='C:\users\user\testfile.txt'}; Invoke-WebRequest -Uri https://api.anonfiles.com/upload -Method POST -Body $postParams
(2)
Invoke-WebRequest -UseBasicParsing https://api.anonfiles.com/upload -ContentType "application/json" -Method POST -InFile "C:\users\user\testfile.txt"
(3)
$file=[io.file]::readallbytes('c:\users\user\testfile.txt')
Invoke-WebRequest -UseBasicParsing https://api.anonfiles.com/upload -ContentType "application/json" -Method POST -Body "{ '#file':'"$file"'}"
None of it works. I canot believe it's so hard to replace an curl oneliner in powershell... The error in each case is a 400 http error, the request is wrong.
How do I send the above mentioned curl-request equivalent in powershell? The site is https://anonfiles.com/docs/api
I gave up. It's not possible in Powershell.
My App will just download curl.exe as standalone from now on, if it's not there.

I'm trying to get data back from an API online using Powershell with the command Invoke-WebRequest -UseBasicParsing $request_string -Method Get -Headers $headers) but am getting back Invoke-WebRequest : The remote server returned an error: (403) Forbidden.
I am supplying a $headers dictionary. Strangely, I can access the API using Postman, Python, and cURL. It's only when using Powershell commands that I get the 403 error. In fact, I used Postman's Code Snippet feature to generate my Powershell code, and it still doensn't work! Postman's Powershell Code Snippet was:
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Authorization", "Bearer {removed for security}")
$response = Invoke-RestMethod '{removed for security}' -Method 'GET' -Headers $headers
$response | ConvertTo-Json
To recap, both Invoke-WebRequest and Invoke-RestMethod don't work.
Any help here is much appreciated.
Thanks!
Figured it out on my own.
The API vendor enforced https requirement instead of just http. Apparently, Postman, Python, and cURL can figure that out on their own and change the request accordingly, but Powershell cannot.
Is there any way of using the POST command in PowerShell to add clients to my Clockify workspace?
Clockify has an API so I wonder how to do this. Anybody has experience with that?
You can use the following command to POST to a REST endpoint:
Invoke-RestMethod -Method POST -Uri 'rest api uri' -Credential 'credentials to endpoint' -Headers 'headers passed' -Body 'Content Body' -ContentType 'text? json? xml?'

I am trying to download package from the below link using powershell.
https://www.tenable.com/downloads/nessus-agents
i do not have direct link for these package also when i click on download it ask to agree. I was able to do it on Linux using command shown below. Kindly advise how can i do it in windows.
"wget --no-check-certificate --post-data='accept="I accept the terms of this license"&x=""&sid=5mcia8gchg28attkc9oarah153&p=NessusAgent-7.4.2-amzn.x86_64.rpm' 'https://www.tenable.com/downloads/nessus-agents' -O NessusAgent-7.4.2-amzn.x86_64.rpm"
could not find anything tried option with invoke-webrequest
Invoke-RestMethod -Uri 'https://www.tenable.com/downloads/nessus-agents'
There's a GET query string parameter that indicates acceptance.
Simply add i_agree_to_tenable_license_agreement=true to your query string parameters.
Invoke-WebRequest -Uri 'https://www.tenable.com/downloads/api/v1/public/pages/nessus-agents/downloads/9762/download?i_agree_to_tenable_license_agreement=true' -OutFile 'NessusAgent-7.4.2-x64.msi'
You can easily get the IDs of the other files from their API endpoint like so:
(Invoke-WebRequest -Uri 'https://www.tenable.com/downloads/api/v1/public/pages/nessus-agents' | ConvertFrom-Json).downloads | Format-Table -AutoSize
This is similar syntax in Powershell, but it's just downloading a file with contents "OK".
$body = 'accept="I accept the terms of this license"&x=""&sid=5mcia8gchg28attkc9oarah153&p=NessusAgent-7.4.2-amzn.x86_64.rpm'
$uri = 'https://www.tenable.com/downloads/nessus-agents'
$resp = Invoke-WebRequest -Method Post -Body $body -Uri $uri -OutFile .\NessusAgent-7.4.2-amzn.x86_64.rpm
Maybe the "sid" variable needs to change per request.
I'm using Powershell v4.
I am calling a POST API and want to see the response when I run Invoke-RestMethod but it just shows a new line.
How can I output the response from the API to the console? I have tried running it in a script with Write-Host and Write-Output, but nothing appears on the console screen.
PowerShell script:
$Response = Invoke-RestMethod -Uri https://localhost:8081/myAPI -Body '{"username":"xyz","password":"xyz"}' -ContentType application/json -Method POST
Write-Host $Response
I can see the response when I curl the API but cannot see it in my PowerShell script which I need to use.
CURL
curl -H "Content-Type: application/json" -X POST -d '{"username":"xyz","password":"xyz"}' https://localhost:8081/myAPI
It looks like its not even hitting the API as nothing appears in the API logs when triggering from Powershell. Not sure how to resolve that if that is the problem.
Your command has a syntax error. Your contenttype is not in proper format.
You have:
-ContentType application/json
Change it to:
-ContentType "application/json"
I am trying to submit a form using invoke-webrequst cmdlet, and this is the code
$postParams = #{regno='1234567';dob='01/01/1997';B1='Get Marks'}
$response = Invoke-Webrequest -Uri ("http://studentresulsts/res.asp") -Body $postParams -Method Post -Debug -OutFile out.html
VERBOSE: POST http://studentresulsts/res.asp with -1-byte payload
VERBOSE: received 13-byte response of content type text/html
The $response comes back as 'Access Denied' (13-byte response)
The payload length is shown as 1-byte while $postParams is clearly more than that. Wondering if that's the reason I am getting 'Access Denied'.
Checked the form manually in browser and it works fine with correct field values.
I am using powershell 4.0
Answer : Okay, I was missing referrer URL in the header which the server was looking for, then I included referrer and it works fine :) . My new script looks like this. Thanks for your help...
$postParams = #{regno='1234567';dob='01/01/1997';B1='Get Marks'}
$headervals = #{'Referer'='http://studentresulsts/gdslplus/gdslform.htm';'Content-Type'='application/x-www-form-urlencoded'}
$response = Invoke-Webrequest -Uri ("http://studentresulsts/res.asp") -Body $postParams -Method Post -Debug -OutFile out.html
The fact that you don't have to manually authenticate does not mean the access isn't verified(e.g. trusted sites in IE).
Perhaps you are missing a crucial header?
