Getting error while uploading larger files using php dropbox api

Srinivas R.1

Hi There,

We have used PHP Dropbox API
to upload files to Dropbox account. But while uploading larger files (500MB from localhost (apache)) we are getting the following errors.

Can you please look into this and help me out on this ASAP.

Error

Fatal error: Uncaught exception 'DropboxException' with message 'cURL-Error (56): SSL read: error:00000000:lib(0):func(0):reason(0), errno 10053' in \wamp\www\dropbox_api\DropboxClient.php on line 534

Please help us ASAP. Thanks for your help in advance.

Thanks,

Srinivas Reddy .A

For large files like this, you should use chunked uploading instead:

Thanks Gregor. Can you please provide an example for this.

Greg-DB

Unfortunately I don't believe we have sample code for that in particular. The documentation I linked to describes how to use it though, so give it a try and let us know if you run into any issues.

Srinivas R.1

Hi Gregory, Thanks for your reply. I want to know that the provided above link is for what version of the API? Is it 1 or 2.

Thanks

Steve M.

It's for v1 of the API.

Srinivas R.1

Hi Steve,

Can you please provide an example as said above. I am unable to find how to call and how it work. Please help me on this. Thanks

Steve M.

As Greg said, we don't have an example that uses that method, but we'll be happy to help if you run into any issues once you give it a try.

Srinivas R.1

Thanks Steve, will try and let you know if any errors or issues will face. thanks for your help.

Srinivas R.1

Steve, can you provide the download link for the files that are in the above link.

Steve M.

I suppose you could download via https://github.com/dropbox/dropbox-sdk-php/tree/gh-pages ("Download ZIP" button) if you needed the documentation offline.

Srinivas R.1

Sorry for the misunderstanding, actually I need to download core files not the documentation files.

Thanks

Steve M.

I don't know what "core files" means.

Srinivas R.1

I mean all the scripting files PHP.

Steve M.

It's just the Dropbox PHP SDK. Is that not what you're already using?

Steve M.

In any case, the SDK is here: https://www.dropbox.com/developers-v1/core/sdks/php.

Srinivas R.1

No Steve, its a single file and don't have the method "chunkedUploadStart'

Srinivas R.1

Hi Steve,

I am trying to upload a 500 MB file. May I know how much time will take upload to dropbox/apps folder using the PHP API.

Thanks,

Srinivas

Srinivas R.1

Please let me know just rough time not exact time.

Steve M.

That would depend on the available bandwidth between your servers and Dropbox's servers, the chunk size you choose, etc. I can't make a guess, but you might try uploading a smaller file and then multiplying.

Srinivas R.1

Thanks Steve, can I change the "$DEFAULT_CHUNK_SIZE" value to some high than 4MB, is that works if I change that value.

Steve M.

I recommend using https://dropbox.github.io/dropbox-sdk-php/api-docs/v1.1.x/class-Dropbox.Client.html#_uploadFileChunked. You can specify the chunk size you want there.

Srinivas R.1

What is the maximum size we can give, is there any limit for that value.

Steve M.

From https://www.dropbox.com/developers-v1/core/docs#chunked-upload:

"Chunks can be any size up to 150 MB."

Hi Steve,

The error message is: "'inStream' has bad type; expecting resource, got boolean'". That's indicating that $inStream, the third parameter to uploadFileChunked, per the documentation, which is supposed to be a resource, was actually a boolean. In your code, you're giving the variable $f for that parameter, so you should check why that isn't the type you're expecting.

You're getting your $f via fopen, and the documentation for that says:

"Returns a file pointer resource on success, or FALSE on error."

So, it's likely that fopen is failing with some error that you need to handle/resolve, causing to $f to be false.

Greg-DB

By the way, for the sake of security, you should disable that access token now that you've shared it publicly. You can do so by revoking access to the app entirely, if the access token is for your account, here:

https://www.dropbox.com/account/security

Or, you can disable just this access token using the /disable_access_token endpoint:

https://www.dropbox.com/developers/core/docs#disable-token

Srinivas R.1

Thanks Greg, the issue is from my side and there is limit to upload file to 5MB max size. But I am uploading 25MB file, so its giving error. Finally we increased the size and its working as expected.

Also, we have disabled the token and using the new token.

Thanks
