Titanium Appcelerator Javascript Dropbox API v2

I needed a library that would use the new Dropbox API v2. Not finding any, I decided to create this module/document, which uses the Dropbox API v2 HTTP .

This module uses OAuth 2.0 authorization token flow, then you must first create a Dropbox App key. For each API method, it is available the complete documentation and a test. You can also consult the official documentation directly ;)

Enjoy

Download the latest release ZIP-file and consult the Titanium Documentation on how install it.

Requirements

The ti.webdialog module
The ti.deeply module (Android only)
Dropbox requires a redirect URI set to the Dropbox Console App, in order to get a valid token. This url is the same one you will use in the redirectUri parameter of the TiDropbox.init() method. In this project I use the redirect URI https://astrovicapps.com/_apptest/tidropbox_cb.html. You will have to create your own and host it somewhere. You can use the contents of my tidropbox_cb.html file. You just need to replace const scheme = "dropbox"; with the one used in you tiapp.xml:

<!-- tidropbox_cb.html file content -->
<html>
    <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=yes">
    <script type="text/javascript">
        const isAndroid = /(android)/i.test(navigator.userAgent);
        const isHuawei = /(huawei)/i.test(navigator.userAgent);
        const urlParams = new URLSearchParams(window.location.search);
        const code = urlParams.get('code');
        const scheme = "tidropbox"; // <-- Must be the one used in the tiapp.xml public.mime-type string and android:scheme value, and in app_mime_scheme in TiDropbox.init()
        const host = "dropbox_token";
        var url = scheme + "://" + host +"?" + (code || window.location.hash);
        var intent = "intent://"+host+"?"+ (code || window.location.hash) + "#Intent;scheme="+scheme+";action=android.intent.action.VIEW;end";
        console.log(window.location);
        console.log("isAndroid: --> ", isAndroid);
        console.log("isHuawei: --> ", isHuawei);
        setTimeout(function(){
            document.getElementById("token").href = isAndroid || isHuawei ? intent : url;
            //document.getElementById("write_token").innerText = isAndroid ? intent : url;
            if (isHuawei) {
                window.location = intent;
            } else {
                window.location = isAndroid ? intent : url;
            }
            window.close();
        },100);
        function closeWindow() {
            window.close();
        }
    </script>
  </head>
  <body>
    <div style="text-align:center;">
        <a id="token" href="" onclick="closeWindow()">
            <button>OPEN APP</button>
        </a>
        <!--p id="write_token"></p-->
    </div>
  </body>
</html>

tiapp.xml

The login flow to obtain the token requires the use of the system browser. In order to get back to the app, you need to add an activity to your android manifest, which will be used by the ti.deeply module, and a public.mime-type string on iOS. iOS public.mime-type key string, Android android:scheme value and app_mime_scheme value must be the ones you use in the tidropbox_cb.html redirect URI file:

tidropbox_cb.html	tiapp.xml iOS	tiapp.xml Android	TiDropbox.init()
`scheme` value	`public.mime-type` key string	`android:scheme` value	`app_mime_scheme` value

- init

TiDropbox.init(parameters)

Parameters	Type	Required	Description
APP_KEY	String	✅	App key in Dropbox Console App
APP_SECRET	String	✅	App secret in Dropbox Console App
redirectUri	String	✅	One of your OAuth2 Redirect URIs set to Dropbox Console App
response_type	String	✅	`code` or `token`. Token flow expires after 4 hours
app_mime_scheme	String	✅	App mime/scheme set to tiapp.xml and used inside your redirect URI page (https://../tidropbox_cb.html) to be able to get back to the app after login

You need a Dropbox App key, and a redirectUri which must be configured on Redirect URIs field of your Dropbox App Settings, on OAuth 2 section.

var TiDropbox = require("ti.dropbox").TiDropbox;
TiDropbox.init({
    APP_KEY: '<YOUR APP KEY HERE>', /*<YOUR APP KEY HERE>*/
    APP_SECRET: '<YOUR APP SECRET HERE>', /*<YOUR APP SECRET HERE>*/
    redirectUri: 'https://astrovicapps.com/_apptest/tidropbox_cb.html', /*<YOUR OAuth2 Redirect URI SET TO DROPBOX APP CONSOLE>*/
    response_type: "code", // "token" or "code". Token flow expires after 4 hours!
    app_mime_scheme: "tidropbox" // *<YOUR APP MIME SCHEME HERE SET TO TIAPP.XML>*/
});

- generateAuthUrl

TiDropbox.generateAuthUrl(callback)

Callback parameters	Type	Description
success	Boolean	Response result

This allows you to generate a token to be able to invoke methods.

TiDropbox.generateAuthUrl(function(e){
    if(e.success){
      // I'm logged, now I can call any method
      Titanium.UI.createAlertDialog({
          title: "AUTH SUCCESS",
          message: e.msg + "\n" + "Your access token is: " + e.access_token,
          buttonNames: ['OK']
      }).show();
    }else{
      Titanium.UI.createAlertDialog({
          title: "AUTH PROBLEM",
          message: e.msg,
          buttonNames: ['OK']
      }).show();
    };
});

- callMethod

TiDropbox.callMethod(parameters)

Parameters	Type	Required	Description
methodStr	String	✅	Represent API target. It contains Dropbox's namespace and method name: `"files/upload"` or `"sharing/share_folder"` or more at /lib/dropboxAPIv2.js
paramsObj	Object	✅	Parameters object, depends on resource field
fileBin	Blob/null	✅	File to upload, depends on resource field
onSuccessCallback	Function	✅	Callback on succes
onErrorCallback	Function	✅	Callback on error
callMethodXhrObjCallback	Function		Return directly the TiDropbox.xhr object of the current `TiDropbox.callMethod`, so you can invoke all xhr methods you need: abort, onload, onsendstream, ecc..

After obtaining a valid token, you can call any method:

// Upload the a.txt file to my app's Dropbox home 
TiDropbox.callMethod({
    methodStr: "files/upload",
    paramsObj: {
        path: "/a.txt",
        mode: "add",
        autorename: true,
        mute: false
    },
    fileBin: Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, "a.txt").read(),
    onSuccessCallback: (xhr) => {
        console.log("onSuccessCallback checkins response-> " + xhr.responseText);
    },
    onErrorCallback: (e) => {
        console.error("onErrorCallback checkins response-> " + JSON.stringify(e));
        if (JSON.stringify(e).indexOf("invalid_access_token") != -1) {
            //The session has expired, I need a new token };
            // Do something...			
        }
    },
    callMethodXhrObjCallback: (currentCallMethodXhr) => {
        currentCallMethodXhr.onsendstream = function (e) {
            if (e.progress) {
                console.log(JSON.stringify('Upload progress --> ' + (e.progress * 100) + '%'));

        }
    }
});

msg	String	Description of the response result

Revoke the access token.

TiDropbox.revokeAccessToken(function (e) {
    if (e.success) {
        // Logout, do something...
        Titanium.UI.createAlertDialog({
            title: "REVOKE AUTH SUCCESS",
            message: e.msg,
            buttonNames: ['OK']
        }).show();

Guidelines for pull requests

Every contribution and pull requests are welcome! This repository is a module/document. So you can contribute both to the documentation, that to new versions of the module.

Pull requests for new module version

If you want to create a new module version, to edit or add new methods, do not edit the modules/ folder directly! But you have to delete modules/commonjs folder. You should edit the source files in /lib folder instead.

After making your changes, to create a new version of the module you have to follow the following steps:

Increase the version number in package.json file, in the root folder.
Uses Titaniumifier to generate the zip module, with the command:

$ titaniumifier --in . --out ./dist
Import your new ti.dropbox-commonjs-x.x.x.zip module in the project. This will create the modules/commonjs folder you had removed earlier, with the new version of the module.

All done :) Now you can send your pull request.
