(PowerShell) REST Upload Bandwidth Throttle

Demonstrates how to use upload bandwidth throttling with the REST API. This example will upload a file to Drobox using a file stream, with a limit on the bandwidth that can be used for the transfer.

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

# A Dropbox access token should have been previously obtained.
# Dropbox access tokens do not expire.
# See Dropbox Access Token.

# To use bandwidth throttling, the connection should be made using the socket API.
# This provides numerous properties to customize the connection, such as
# BandwidthThrottleDown, BandwidthThrottleUp, ClientIpAddress, ClintPort, Http Proxy,
# KeepAlive, PreferIpv6, RequireSslCertVerify, SoRcvBuf, SoSndBuf, SoReuseAddr,
# SOCKS proxy, TcpNoSDelay, TlsPinSet, TlsCipherSuite, SslAllowedCiphers, etc.

$socket = New-Object Chilkat.Socket
$maxWaitMs = 5000
$success = $socket.Connect("content.dropboxapi.com",443,$true,$maxWaitMs)
if ($success -ne $true) {
    $($socket.LastErrorText)
    $("Connect Fail Reason: " + $socket.ConnectFailReason)
    exit
}

# Set the upload bandwidth throttle rate to 50000 bytes per second.
$socket.BandwidthThrottleUp = 50000

$rest = New-Object Chilkat.Rest

# Tell the REST object to use the connected socket.
$rest.UseConnection($socket,$true)

# The remainder of this example is identical to the example at:
# Dropbox File Stream Upload.

# Add request headers.
$rest.AddHeader("Content-Type","application/octet-stream")
$rest.AddHeader("Authorization","Bearer DROPBOX_ACCESS_TOKEN")

# The upload "parameters" contained in JSON passed in an HTTP request header.
# This is the JSON to be added in this example:
# { 
#    "path": "/Homework/lit/hamlet.xml",
#    "mode": "add",
#    "autorename": true,
#    "mute": false
# }

$json = New-Object Chilkat.JsonObject
$json.AppendString("path","/Homework/lit/hamlet.xml")
$json.AppendString("mode","add")
$json.AppendBool("autorename",$true)
$json.AppendBool("mute",$false)
$rest.AddHeader("Dropbox-API-Arg",$json.Emit())

# Almost ready to go...
# Let's setup a file stream to point to a file.
$fileStream = New-Object Chilkat.Stream
$fileStream.SourceFile = "qa_data/xml/hamlet.xml"

# Do the upload.  The URL is https://content.dropboxapi.com/2/files/upload.
# We already connected to content.dropboxapi.com using TLS (i.e. HTTPS),
# so now we only need to specify the path "/2/files/upload".

# Note: The file is streamed directly from disk.  (The entire
# file will not be loaded into memory.)
$responseStr = $rest.FullRequestStream("POST","/2/files/upload",$fileStream)
if ($rest.LastMethodSuccess -ne $true) {
    $($rest.LastErrorText)
    exit
}

# When successful, Dropbox responds with a 200 response code.
if ($rest.ResponseStatusCode -ne 200) {
    # Examine the request/response to see what happened.
    $("response status code = " + $rest.ResponseStatusCode)
    $("response status text = " + $rest.ResponseStatusText)
    $("response header: " + $rest.ResponseHeader)
    $("response body (if any): " + $responseStr)
    $("---")
    $("LastRequestStartLine: " + $rest.LastRequestStartLine)
    $("LastRequestHeader: " + $rest.LastRequestHeader)
    exit
}

# The response is JSON.
$jsonResp = New-Object Chilkat.JsonObject
$jsonResp.EmitCompact = $false
$jsonResp.Load($responseStr)

# Show the JSON response.
$($jsonResp.Emit())

# Returns JSON that looks like this:
# { 
#   "name": "hamlet.xml",
#   "path_lower": "/homework/lit/hamlet.xml",
#   "path_display": "/Homework/lit/hamlet.xml",
#   "id": "id:74FkdeNuyKAAAAAAAAAAAQ",

#   "rev": "9482db15f",
#   "size": 279658
# }

# Sample code to get data from the JSON response:
$size = $jsonResp.IntOf("size")
$("size = " + $size)

$rev = $jsonResp.StringOf("rev")
$("rev = " + $rev)

$clientModified = $jsonResp.StringOf("client_modified")
