I am trying to write a ps 3.0 script that will post a list of 200 words to a web server. After I have prepared the list, I use:
Invoke-WebRequest -Uri $url -Method POST -Body $PostParams -OutFile C:...\upload_log.tmp.txt
When I run this script from the ISE editor it works fine. However, when I run it from outside the editor (cmd, ps shell, task scheduler) I get this error message:
Invoke-WebRequest : You must write ContentLength bytes to the request stream
Any suggestions?

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 download an Artifactory folder as a tar.gz file using the PowerShell command line. In Bash, the following command does the job:
curl -i -v -XGET -H 'X-JFrog-Art-Api:<my API key>' "https://artifactory.<myrepo.com>/path/to/files?archiveType=tar.gz" --output ./file_location/filename.tar.gz
In PowerShell, however, this doesn't seem to work:
Invoke-RestMethod -uri "https://artifactory.<myrepo.com>/path/to/files?archiveType=tar.gz" -Method 'Get' -OutFile .\file_location\filename.tar.gz -H #{'X-JFrog-Art-Api' ='<my API key>';'Content-Type'='multipart/form-data'}
This operation creates filename.tar.gz, but the file is just a HTML file giving the directory structure rather than the actual files.
If I only want an individual file, I can use PowerShell to download files (not an archive) with:
Invoke-RestMethod -uri "https://artifactory.<myrepo.com>/path/to/files/filename.xyz" -Method 'Get' -OutFile .\file_location\filename.xyz -H #{'X-JFrog-Art-Api' ='<my API key>';'Content-Type'='multipart/form-data'}
And filename.xyz is transferred to the local machine. So I'm a bit confused with why the tool to make an archive fails.
I figured it out!
Invoke-RestMethod -Uri "https://my-artifactory-server/artifactory/api/archive/download/path/to/some/folder?archiveType=zip -Method "Get" -Headers #{"Authorization"="Basic $my_artifactory_api_token"; 'Content-Type'='multipart/form-data'} -Outfile c:\destination_location\folder.zip
You need to add "api/archive/download" to the Uri, after the hostname.
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 am trying to download file from the web using following command
Invoke-WebRequest $url -OutFile $filePath -Headers $Headers
I have argument, which contains this url and it is passed as parameter
[string]$artifactHttpAddress = $args[2]
Currently its value is
http://10.45.48.26/httpAuth/repository/downloadAll/TeamCityTest_Build/529:id/artifacts.zip
So, when I try to invoke WebRequest with following command
Invoke-WebRequest $artifactHttpAddress -OutFile c:/test.zip -Headers $Headers
it is downloading empty zip file .
but when I try to assign this url to the variable and invoke web request
$url = "http://10.45.48.26/httpAuth/repository/downloadAll/TeamCityTest_Build/529:id/artifacts.zip"
Invoke-WebRequest $url -OutFile c:/test.zip -Headers $Headers
It is working correctly, downloads zip file, which have some content in it.
I tried following script
Write-Host([string]$url -eq [string]$artifactHttpAddress)
Write-Host([string]$url)
Write-Host([string]$artifactHttpAddress)
It outputs
False
http://10.45.48.26/httpAuth/repository/downloadAll/TeamCityTest_Build/528:id/artifacts.zip
http://10.45.48.26/httpAuth/repository/downloadAll/TeamCityTest_Build/531:id/artifacts.zip
What is happening and why?
p.s. this script is inside ScriptBlock
It looks to me, based on your output, that $url and $artifactHttpAddress are not the same value. Does the ZIP file exist at the URL with 531 in it?
I run the following command in my PS script:
$apiResult = Invoke-WebRequest -Uri $myURL -Body $body -DisableKeepAlive -Headers $headers -Method Post -TimeoutSec 120 -ContentType $contentType -UseBasicParsing
This fails on the following error:
Unable to cast object of type \u0027System.Management.Automation.PSObject\u0027 to type \u0027System.String\u0027
Here is the catch:
The types of the supplied variables are System.String (for $body, $myURL, $contentType) and System.Collection.Hashtable (for $headers)
This fails without calling the actual service behind the URL (verified in service logs)
Running this script with the same parameters on the machine with Powershell version 4 does not create this error and actually returns expected result
I believe this is a bug but i have not been able to find any mention of it on google or any other areas including documentation.
Well...After long time digging I found that the issue was one of the values in my headers hashtable was not a string! not sure why this passes on powershell 4...maybe the casting there is more flexable than in PS3
