Unable to Add Text File to Azure DevOps Repo using RestApi - File containing '\'

Question

I am trying to add a file "AssemblyInfo.cs" which contain a '' as part of the text.

When trying to use the RestAPI to do it i get Error 400

After Removing the Char RestApi pass

i am using the following code to convert the text to Json - Powershell based

function GetJSContentCS {
    param (
        $filepath
    )
    $read = (Get-Content -Encoding UTF8 -RAW -Path $filepath) -replace "(?s)`r`n\s*$"
    $jscontent=''
    foreach ($item in $read) {
        $jsitem = $item+'\n'
        $jsitem = $jsitem.replace('"','\"')
        $jscontent += $jsitem
    }
    return $jscontent
}
GetJSContentCS -filepath 'C:\temp\AssemblyInfo (2).cs'

Any Advise Would be great

Answer 1

The problem is missing a \ character after c: in the converted Json.

By running the PowerShell the converted Json is :

[assembly: XmlConfigurator(ConfigFile = @\"c:\appsLogging.xml\", Watch = true)]\n

However, the correct Json should like this:

[assembly: XmlConfigurator(ConfigFile = @\"c:\\appsLogging.xml\", Watch = true)]

Please try the following script to convert the text to Json:

function GetJSContentCS {
    param (
        $filepath
    )
    $read = (Get-Content -Encoding UTF8 -RAW -Path $filepath) -replace "(?s)`r`n\s*$"
    cls
    Write-Host $read 
    $jscontent=''
    foreach ($item in $read) {
        $jsitem = $item.replace('"','\"')
        $jsitem = $jsitem.replace(':\',':\\')
        $jscontent += $jsitem
    }
    return $jscontent
}
GetJSContentCS -filepath 'C:\temp\AssemblyInfo.cs'

UPDATE:

Sample PowerShell script for your reference to call the Pushes - Create REST API to add a file :

Param(
[string]$orgurl = “https://dev.azure.com/{organization}",
[string]$project = “ProjectName”,
[string]$repoid = “166d743e-623a-4bdd-923b-6af25ebfdf9a”,
[string]$oldObjectId = “cbfc5c415de65cf40bcc9509d8ee286e7c990a56”, #Previous commit ID
[string]$user = “”,
[string]$token = “PAT”
)

# Base64-encodes the Personal Access Token (PAT) appropriately
$base64AuthInfo = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(("{0}:{1}" -f $user,$token)))

#Get contents from the AssemblyInfo.cs file and convert to the correct Json. 

function GetJSContentCS {
    param (
        $filepath
    )
    $read = (Get-Content -Encoding UTF8 -RAW -Path $filepath) -replace "(?s)`r`n\s*$"
    cls
    Write-Host $read 
    $jscontent=''
    foreach ($item in $read) {
        $jsitem = $item.replace('"','\"')
        $jsitem = $jsitem.replace(':\',':\\')
        $jscontent += $jsitem
    }
    return $jscontent
}
GetJSContentCS -filepath 'C:\temp\AssemblyInfo.cs'

    $value = @"
