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)

}

$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")
