(PHP ActiveX) Download File from Dropbox into a String Variable

Demonstrates how to download a file from Dropbox directly into a string variable.

Chilkat ActiveX Downloads

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.

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

//  Connect to Dropbox
$success = $rest->Connect('content.dropboxapi.com',443,1,1);
if ($success != 1) {
    print $rest->LastErrorText . "\n";
    exit;
}

//  Add request headers.
$rest->AddHeader('Authorization','Bearer DROPBOX_ACCESS_TOKEN');

//  The download "parameters" are contained in JSON passed in an HTTP request header.
//  This is the JSON indicating the file to be downloaded:
//  {
//     "path": "/jack.txt",
//  }

$json = new COM("Chilkat_9_5_0.JsonObject");
$json->AppendString('path','/jack.txt');
$rest->AddHeader('Dropbox-API-Arg',$json->emit());

//  The content of the file on Dropbox is returned.
$fileContent = $rest->fullRequestNoBody('POST','/2/files/download');
if ($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): ' . $fileContent . "\n";
    print '---' . "\n";
    print 'LastRequestStartLine: ' . $rest->LastRequestStartLine . "\n";
    print 'LastRequestHeader: ' . $rest->LastRequestHeader . "\n";
    exit;
}

//  Show the file content that was downloaded:
print $fileContent . "\n";
print '----' . "\n";

//  Information about the downloaded file is also available as JSON in a response header.
//  The "dropbox-api-result" response header contains the information.  For example:
$apiResult = $rest->responseHdrByName('dropbox-api-result');
print $apiResult . "\n";

//  In this case, the pretty-formatted dropbox-api-result JSON looks like this:
//  {
//    "name": "jack.txt",
//    "path_lower": "/jack.txt",
//    "path_display": "/jack.txt",
//    "id": "id:yqx4-tE_NKAAAAAAAAAAAQ",
//    "client_modified": "2016-06-02T20:42:11Z",
//    "server_modified": "2016-06-02T20:42:11Z",
//    "rev": "8482db15f",
//    "size": 42
//  }

//  Load the JSON, pretty-print it, and demonstrate how to get some values...
$jsonResult = new COM("Chilkat_9_5_0.JsonObject");
$jsonResult->EmitCompact = 0;
$jsonResult->Load($apiResult);
//  Show the JSON pretty-printed...
print $jsonResult->emit() . "\n";

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

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

$clientModified = $jsonResult->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";
