Answer 1

Use splatting .

$CurlArgument = '-u', 'xxx@gmail.com:yyyy',
                '-X', 'POST',
                'https://xxx.bitbucket.org/1.0/repositories/abcd/efg/pull-requests/2229/comments',
                '--data', 'content=success'
$CURLEXE = 'C:\Program Files\Git\mingw64\bin\curl.exe'
& $CURLEXE @CurlArgument

Answer 2

In Powershell 3.0 and above there is both a Invoke-WebRequest and Invoke-RestMethod. Curl is actually an alias of Invoke-WebRequest in PoSH. I think using native Powershell would be much more appropriate than curl, but it's up to you :).

Invoke-WebRequest MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849901.aspx?f=255&MSPPError=-2147217396

Invoke-RestMethod MSDN docs are here: https://technet.microsoft.com/en-us/library/hh849971.aspx?f=255&MSPPError=-2147217396

Instead of curl you can use this command:

(New-Object System.Net.WebClient).DownloadString("http://google.com")

Answer 4

Or another option you could just call curl.exe using splatting as follows.

> curl.exe '-u', 'xxx@gmail.com:yyyy',
 '-X', 'POST',
 'https://xxx.bitbucket.org/1.0/repositories/abcd/efg/pull-requests/2229/comments',                
 '--data', 'content=success'

To know where is curl.exe using this command Get-Command curl.exe

Other option is to delete aliases curl command with Invoke-WebRequest

To see and delete aliaes in PowerShell

>Get-Aliases
>Remove-Item alias:curl

Then just runing command without '.exe'

> curl '-u', 'xxx@gmail.com:yyyy',
 '-X', 'POST',
 'https://xxx.bitbucket.org/1.0/repositories/abcd/efg/pull-requests/2229/comments',                
 '--data', 'content=success'

I hope this would helps.

PowerShell now supports default aliases, if you type help curl
You will get below output

NAME
    Invoke-WebRequest

SYNTAX
    Invoke-WebRequest [-Uri] <uri> [-UseBasicParsing] [-WebSession <WebRequestSession>] [-SessionVariable <string>] [-Credential <pscredential>] [-UseDefaultCredentials] [-CertificateThumbprint <string>] [-Certificate
    <X509Certificate>] [-UserAgent <string>] [-DisableKeepAlive] [-TimeoutSec <int>] [-Headers <IDictionary>] [-MaximumRedirection <int>] [-Method {Default | Get | Head | Post | Put | Delete | Trace | Options | Merge | Patch}] [-Proxy
    <uri>] [-ProxyCredential <pscredential>] [-ProxyUseDefaultCredentials] [-Body <Object>] [-ContentType <string>] [-TransferEncoding {chunked | compress | deflate | gzip | identity}] [-InFile <string>] [-OutFile <string>] [-PassThru]
     [<CommonParameters>]


ALIASES
    iwr
    wget
    curl


REMARKS
    Get-Help cannot find the Help files for this cmdlet on this computer. It is displaying only partial help.
        -- To download and install Help files for the module that includes this cmdlet, use Update-Help.
        -- To view the Help topic for this cmdlet online, type: "Get-Help Invoke-WebRequest -Online" or
           go to https://go.microsoft.com/fwlink/?LinkID=217035.

So to download a file you can type

curl -Uri "https://www.example.com/myfile.txt" -OutFile myfile.txt
