I am partly confused because of this analogy: We can easily view a JPG or PNG file and we can also display them in a browser using their dataURI (base-64)... but when we save that base-64 string as a JPG or PNG file, the image cannot be seen. Therefore, I cannot understand how should I read the contents of the file to be able to upload it on dropbox (keeping in mind that a file can be around 150MB too) and still retain how the file originally was.

I am trying to upload files directly to dropbox [from a browser / web application], The "uploadFile" function on the code API needs the file to be uploaded available on the server, this puts me in trouble, because I do not want any files to be uploaded to my server and from there to dropbox.

As other answers have noted, each session uploading or downloading the file will need to have access to a dropbox token. Sending someone else's token to a user is a security issue since having the token will give them complete control over the dropbox account. The only way to make this work is to have each person authenticate with Dropbox and get their own token.

I might also add that something that is not shown in the dropbox sdk examples is that you can upload a blob object to dropbox; this is useful for instance if you want to dynamically extract images from a canvas and upload them and don't want to upload something that has been selected from the file system via the file uploaded input.

In order to make that API call though, you first need an access token for the user. You can get an access token for the user by sending them through the OAuth app authorization flow (details and links in my previous comment). That involves sending them to the Dropbox web page where they can choose whether or not to authorize your app. Unlike actual API calls, such as /2/users/get_current_account, that step on the www.dropbox.com/oauth2/authorize web page cannot be done programmatically via ajax.

Based on your code here, it looks like you're attempting to access www.dropbox.com/oauth2/authorize via an ajax call, but it's actually a web page, not an API endpoint, so you shouldn't access it via ajax.

I was recently asked for a "Hello World" example of writing a file to Dropbox using JavaScript. The Getting Started guide that comes with dropbox.js is probably the most complete resource for this, but in the true spirit of "Hello, World," I thought I'd share a minimal snippet to accomplish the task:

A better, more complete version of this code is below. This version only requires authentication when the user clicks the button, and this version also provides some error-handling. As a side note, I'm using the Datastore SDK here. You could instead use dropbox.js from GitHub instead. The Datastore SDK includes the same file functionality.

When working with the Dropbox APIs, your app will access Dropbox on behalf of your users. You'll need to have each user of your app sign into dropbox.com to grant your app permission to access their data on Dropbox.

For the first dropbox button example shown above (the wide, default "Choose from Dropbox" button), replace the custom component's iFrame code with the following (update yourAppKeyGoesHere with your app key):

After some successful use, we noticed that the dropboxURL value in the custom component's Model can hang around and cause some unexpected behavior if the text input field is part of a form that is linked to a table that has a "select row to edit" functionality. Basically, the form is trying to default a value into the text input from the table's selected row while the text input is simultaneously trying to default in a lingering value from the custom component's Model.

Hey! @leonidas.petrou4 The best way to do this is by using Javascript SDK as I mentioned before.

As @neerja suggested, you need to create a custom plugin (you need javascript knowledge to do this).

It may be worth uninstalling and re-installing Dropbox on Windows. I've seen a couple issues where Dropbox does some odd things, especially if for example you copied another system's dropbox folder to another system then pointed Dropbox to it. Uninstalling dropbox and starting fresh there would take a lot of things out of the equation.

Make a backup of your vault. This can be either an AgileKeychain like you've put on dropbox that has all of your items, or you can go into Preferences > Backup, and create a new backup. You should be able to use the 'Show Files' button to show the backup files in Finder. Copy the one with the latest date to your desktop. If you've got multiple vaults, using the native backup function is the way to go as the 1 backup file will contain everything for all vaults. Once you've got a backup set aside, you can use the instructions on our Starting Over page. Make sure to restart your Mac afterwards (alternatively run killall cfprefsd in Terminal).

For eons I have stored my arduino sketchbooks on my local computer harddrives. But recently I was introduced dropbox.com and its apps. You can create a dropbox folder and see all the files in dropbox on all your computers and devices (tablets and phones). It's neat. I wonder if anyone is storing their sketchbook folder in dropbox. I'm only doing this for the less serious projects that have their code spread out on multiple computers and keep my main sketchbook on my main computer on local drive.

Here's a snippet below where we get an access token from an access code and get the refresh token from the result. You can get the full example from dropbox-sdk-js]( -sdk-js/blob/b5631e4b5b0e9eb6d3297e1ee57ad29a63d49898/examples/javascript/PKCE-backend/code_flow_example.js#L38).

The Montgomery County Register of Wills encourages the use of the Courthouse Dropbox as well as mail to submit any paperwork. While we are making appointments for in-person visits we are very limited in the number of appointments per day and recommend submitting paperwork by mail or dropbox to expedite the process. ff782bc1db
