PowerShell Requires Chilkat v11.0.0+

Parse Multipart Binary Http Response

See more HTTP Examples

This example demonstrates how to parse an HTTP response that is multipart and contains a binary file, such as a .zip or .pdf. PowerShell

Add-Type -Path "C:\chilkat\ChilkatDotNet47-x64\ChilkatDotNet47.dll"

$success = $false

#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

$http = New-Object Chilkat.Http
$req = New-Object Chilkat.HttpRequest

#  ...
#  Insert code here to construct some kind of HTTP request.
#  this example is to show how to parse a particular kind of response.
#  ...
#  ...

#  Send the request (whatever it may be in your case) to get the HTTP response object.
$resp = New-Object Chilkat.HttpResponse
$success = $http.HttpSReq("www.somedomain.com",443,$true,$req,$resp)
if ($success -eq $false) {
    $($http.LastErrorText)
    exit
}

#  Get the response body (which is expected to be binary)
$respBody = New-Object Chilkat.BinData
$resp.GetBodyBd($respBody)

#  For this example, the response body contains something like this:

#  ------=_Part_21302_2029949381.1547401515443
#  Content-Type: application/xop+xml; charset=UTF-8; type="text/xml"
#  Content-Transfer-Encoding: 8bit
#  Content-ID: <rootpart@ws.jboss.org>
#  
#  <env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'><env:Header></env:Header><env:Body>...</env:Body></env:Envelope>
#  ------=_Part_21302_2029949381.1547401515443
#  Content-Type: application/octet-stream
#  Content-Transfer-Encoding: binary
#  Content-Id: <fileArchivio-7d302908-4d64-43d3-bf4e-79ce806d43b3@ws.jboss.org>
#  
#  BINARY_CONTENT_HERE...
#  
#  ------=_Part_21302_2029949381.1547401515443--
#  

#  Load it into a Chilkat MIME object.
$mime = New-Object Chilkat.Mime
$success = $mime.LoadMimeBd($respBody)
if ($success -eq $false) {
    $($mime.LastErrorText)
    exit
}

$numParts = $mime.NumParts
if ($numParts -lt 2) {
    $("Expected multipart MIME with at least 2 sub-parts.")
    exit
}

#  Get the 1st sub-part, which is the XML.

$part0 = New-Object Chilkat.Mime
$mime.PartAt(0,$part0)

#  Should be OK because we checked NumParts above..
$xmlStr = $part0.GetBodyDecoded()
$($xmlStr)
$("----")

#  Save the 2nd part to a file.  (It is a .zip file in our test case..)

$part1 = New-Object Chilkat.Mime
$mime.PartAt(1,$part1)

$success = $part1.SaveBody("qa_output/attachedZip.zip")

#  Alternatively, we could extract the binary data to a BinData and use elsewhere..
$zipData = New-Object Chilkat.BinData
$success = $part1.GetBodyBd($zipData)
$success = $zipData.WriteFile("qa_output/attachedZip_again.zip")
