(PHP ActiveX) 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.

ActiveX for 32-bit and 64-bit Windows

<?php

//  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 COM("Chilkat_9_5_0.Socket");
$maxWaitMs = 5000;
$success = $socket->Connect('content.dropboxapi.com',443,1,$maxWaitMs);
if ($success != 1) {
    print $socket->LastErrorText . "\n";
    print 'Connect Fail Reason: ' . $socket->ConnectFailReason . "\n";
    exit;
}

//  Set the upload bandwidth throttle rate to 50000 bytes per second.
$socket->BandwidthThrottleUp = 50000;

$rest = new COM("Chilkat_9_5_0.Rest");

//  Tell the REST object to use the connected socket.
$rest->UseConnection($socket,1);

//  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 COM("Chilkat_9_5_0.JsonObject");
$json->AppendString('path','/Homework/lit/hamlet.xml');
$json->AppendString('mode','add');
$json->AppendBool('autorename',1);
$json->AppendBool('mute',0);
$rest->AddHeader('Dropbox-API-Arg',$json->emit());

//  Almost ready to go...
//  Let's setup a file stream to point to a file.
$fileStream = new COM("Chilkat_9_5_0.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 != 1) {
    print $rest->LastErrorText . "\n";
    exit;
}

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

//  The response is JSON.
$jsonResp = new COM("Chilkat_9_5_0.JsonObject");
$jsonResp->EmitCompact = 0;
$jsonResp->Load($responseStr);

//  Show the JSON response.
print $jsonResp->emit() . "\n";

//  Returns JSON that looks like this:
//  {
//    "name": "hamlet.xml",
//    "path_lower": "/homework/lit/hamlet.xml",
//    "path_display": "/Homework/lit/hamlet.xml",
//    "id": "id:74FkdeNuyKAAAAAAAAAAAQ",
//    "client_modified": "2016-06-02T23:19:00Z",
//    "server_modified": "2016-06-02T23:19:00Z",
//    "rev": "9482db15f",
//    "size": 279658
//  }

//  Sample code to get data from the JSON response:
$size = $jsonResp->IntOf('size');
print 'size = ' . $size . "\n";

$rev = $jsonResp->stringOf('rev');
print 'rev = ' . $rev . "\n";

$clientModified = $jsonResp->stringOf('client_modified');
$ckdt = new COM("Chilkat_9_5_0.CkDateTime");
$ckdt->SetFromTimestamp($clientModified);
$bLocalTime = 1;
// dt is a Chilkat_9_5_0.DtObj
$dt = $ckdt->GetDtObj($bLocalTime);
print $dt->Day . '/' . $dt->Month . '/' . $dt->Year . ' ' . $dt->Hour . ':' . $dt->Minute . "\n";
