Javascript Download Image and Uploads to Dropbox
Let's upload a text file to Dropbox
Here we'll prove you how to use our JavaScript SDK and a server-side proxy language to upload a file to Dropbox. We'll employ PHP as our server-side proxy linguistic communication for this tutorial, only you lot tin also apply Node.js, Ruby, Coffee, or Python.
To learn more about using non-PHP proxy languages, take a wait at our web application server tutorial.

2Create a new .html file and save it as index.html into a folder where you'll save the rest of your projection files.
3Create a new .php file and relieve it as proxy-server.php into the same project folder as your index.html file.
4Download the latest Temboo JavaScript SDK and unzip the file.
vChange the name of the resulting folder to js-sdk and move it into the same folder as your index.html file.
sixDownload the latest Temboo PHP SDK and unzip the file.
7Change the name of the resulting folder to php-sdk and move information technology into the same folder as your index.html file. Your project folder should look similar to the screenshot below:
Create a Dropbox Application

xiIf you will only be needing access to your own account, yous can generate an Access Token in the Dropbox App Panel. Click the Generate button in the OAuth two section of your app settings page.
To Admission to Another User's Dropbox
12In guild to access Dropbox accounts other than your own, you will need to complete the OAuth process. If you simply need access to your own business relationship, you tin can skip ahead to the next section.
To begin, get to Dropbox > OAuth > InitializeOAuth in the Temboo lawmaking generation library. In the INPUT section of the page, enter the AppKey institute on your app settings folio within the Dropbox App Console.
13Click the Generate Code button to run InitializeOAuth from the Temboo site. Roll downwardly to the OUTPUT section of the page. Save the CallbackID to use in the next steps.
14The owner of the Dropbox account that your awarding needs to access will need to visit the AuthorizationURL found in the OUTPUT section. They should click the Allow button on the page to grant the awarding permission to access their account. Once they see a blank folio in the browser, it's safety to close the page.
15Once permission has been granted on the AuthorizationURL folio, you're ready to complete the OAuth procedure. Visit Dropbox > OAuth > FinalizeOAuth in the Temboo lawmaking generation library. In the INPUT department of the folio, enter the AppKey and AppSecret establish on your app settings page in the Dropbox App Console.
Supply the CallbackID that was returned in the OUTPUT section of the InitializeOAuth folio.
16Now, with all the required inputs in place, click the Generate Lawmaking button to run FinalizeOAuth from the Temboo site. Ringlet downwards in one case again to the OUTPUT department of the folio. Hither you'll find the AccessToken you lot'll need for any Dropbox processes for this user's account. Save it for later.

17 Become to the Dropbox > Files > Upload page in our lawmaking generation library. From the drop downwards card at the meridian of the page, select Javascript.

20At present supply the FileContent of your text file. We'll but use "Hi world!".
At this point, your INPUT department should look something like this:
21We need to tell Dropbox that our file content is plain text rather than Base64 encoded binary data. To do so, click on OPTIONAL INPUT at the bottom of the INPUT department to reveal more than input fields. In the ContentType field, enter text/plain. You can get out the other fields blank.

Endeavour It Out
23Dropbox won't allow y'all to upload a file if there's already a file with the location and filename specified in the Path input. Delete your examination file in Dropbox so that you lot can run the aforementioned code over again from your JavaScript awarding.
24Curlicue down to find the CODE department of the Choreo page. Copy and paste the code snippet into your alphabetize.html file.
25In the aforementioned file, brand sure that your script source points to the correct location of the temboo.js SDK file.
<!-- Adjust to point at the copy of the Temboo JavaScript SDK on your server --> <script src="js-sdk/js/temboo.js">< /script>
26In the same file, we'll also want to confirm that the location of our proxy is correctly specified. Our server is proxy-server.php.
// Instantiate the customer proxy with the URI of your server proxy var temboo = new TembooProxy('proxy-server.php'); 27You'll notice another code snippet box below the Code section on the Choreo page called Proxy Code. Employ the dropdown card to select PHP, and so re-create and paste the code snippet into your proxy-server.php file.
28In the proxy-server.php file, make sure that the require_once line points to the correct location of the PHP SDK file in the php-sdk binder that you lot downloaded earlier.
require_once('php-sdk/src/temboo.php'); 29Let's likewise make sure that nosotros can encounter the success of our file upload in the browser. In your index.html file, discover the find the line in the showResult success callback function where raw outputs are displayed and change the panel.log statement to a document.write statement:
// Display raw outputs for(var name in outputs) { document.write(name + ': ' + outputs[name]); } 30Run your PHP server.
