Topic: Is it possible to upload files to Amazon using html5 and html4?

In last version there is an example how upload files directly to Amazon using Silverlight and Flash, but is it possible to do the same with html 5 and html 4?

Re: Is it possible to upload files to Amazon using html5 and html4?

Well... yes and no.

First about 'No'.

It is assumed that you place uploader form on your website (domain) and plan to upload to Amazon S3. Actually with html4 you can, but it will never report to you back that it did, thus there is no way to tell whether it was successful or not. Html5 requires Access-Control-Allow-Origin header, which is not yet supported by Amazon S3. But there is a high chance that at some point in future, it will be.

Now about 'Yes' (not tested)

Theoretically one could host uploader form right in the bucket, inside specially constructed html file. It should work (but no chunking, which means no progress for html5). Anyone eager to try? smile

Re: Is it possible to upload files to Amazon using html5 and html4?

Hi davit,

Thank you for your response. It was very helpful!

Re: Is it possible to upload files to Amazon using html5 and html4?

Hi!

I need direct to S3 upload. I am C#/ASP.NET programmer. I see the latest release has the php sample which I am going to begin to attempt to understand and translate to C#.

Questions: I see it only uses Flash & SL runtimes. I assume I am limited to those for Direct to S3?

I assume the PHP I will translate it only for secure signing?

Finally and this is major I assume I can modify the policy as each upload needs a dynamic key to create the s3 version of a folder. I need the filekey to reflect a userid and item id for each record.

Worse I need an event to log each upload in SQL Server in realtime.

Am I asking too much from PLUpload? sad(

Any and all help would be greatly appreciated!

Thanks,

Cary

Yes, you are. No other runtime supports cross-domain uploads currently.

PHP (or any other server-side technology) is required to generate policy and sign it.

Finally and this is major I assume I can modify the policy as each upload needs a dynamic key to create the s3 version of a folder. I need the filekey to reflect a userid and item id for each record.

Policy shown in PHP example is really just an example. User is free to add and modify rules in policy however he needs or desires.

Worse I need an event to log each upload in SQL Server in realtime.

You will get FileUploaded event at the end of upload as usual and you can use right away to do an AJAX request to your server for example, or any other operation.

Re: Is it possible to upload files to Amazon using html5 and html4?

Thanks so very much for responding to my questions.

I have spent the entire weekend working with your control and the jquery-html5-plugin.

http://code.google.com/p/jquery-html5-u … tail?id=12

Using your source code from the *_dev.html sample and the above link I was able to get firebug tracing working no problem with your control.

The jquery-html5-plugin works differently in that the html file is served directly from S3 which I have never seen before.

It requires write acl on the s3 bucket so I have put in a support ticket to Amazon support to make sure that it is possible to secure this as my particular needs are to allow individual customers to have rights only within specific areas of the bucket; i.e. I use their customer id to create keys.

At any rate I was able to even get plupload working with the jquery ui themes which is truly a beautiful aesthetic experience, and I could get it served up direct from S3, but ALAS I have given up on I am both not talented enough a jquery developer, nor do I have the time to integrate the two.

If you look at the jquery-ui-html5 plugin it is only about 100 lines of very terse code, and best of all it works, but the front end is quite 1995ish.

My feeling is that if you were to look at the code, and felt it could create a "secure" upload experience for S3, you would be able to make a profit with a product like this.

I would not hesitate to spend up to several hundred dollars for it as it would work in every modern browser implementation except IE. I tested smile)

The only product I have found with drag & drop that satisfies my needs is the Aurigma ImageUploader but that requires Java. It is quite expensive if you go to their site and they have thousands of customers.

I am in the process of purchasing it, but as mentioned I would not hesitate to purchase a PLUpload S3 HTML5 uploader if it worked as jquery html5 plugin does.

They also use http put, which means they have a progress bar, and the link supplied has an online working sample.

Now that Amazon has offered multi-part resilient resumable uploads I was really hoping I would be able to somehow inject the jquery html5 plugin into your codebase, and then even figure out how to shrink images to thumbs, and have error correction.

The S3 cloud is poised to explode and whoever could offer resumable uploads, resizable thumbs, etc. in html5 ... they are sure to sell thousands of copies as all signs indicate as MA$$ exodus to the cloud.

I am a one man IT department working on a labor intensive project and I always rely upon 3rd party controls like Telerik, Flajaxian, Aurigma to get my site completed before the 22nd century.

I think no company/group of developers is more poised to fill that niche than PLUpload if you only have the will to go for it. You guys are clearly jquery masters as I am just a decent hack....

Just food for thought...

Best,

Cary

Re: Is it possible to upload files to Amazon using html5 and html4?

The only reason why jquery-html5-plugin has to be served up directly from S3 (haven't used it myself, but I believe you smile) is that otherwise it will mean that plugin will have to make cross-domain requests (from one domain where it is hosted to S3 bucket), which is not supported by Amazon S3 currently. Actually you could try and test the same approach for Plupload - try to serve it directly from S3 and it should work. There is no other workaround around this currently (for HTML5 runtime I mean).

If you want to see your issue fixed, do not report it here, do it on - GitHub.

Re: Is it possible to upload files to Amazon using html5 and html4?

I could easily get PLUpload to load from S3 but I am unsure what you mean by, "try to serve it drectly from S3 and it should work.."

S3 will not host anything but static content so I do not believe PHP or C# files can be used in that scenario...

I would be willing to experiment more with this control on S3 but I am confused ...

By the way, I use flajaxian too, and that uses a crossdomain.xml file I keep in my bucket. I am also wondering why that is not a cross-domain request....

At any rate thanks so much for responding to all my posts. It is incredibly helpful!

Thanks,
Cary

Re: Is it possible to upload files to Amazon using html5 and html4?

BTW, are you away of any security implications for hosting the plupload control on S3 versus a web server? Thanks again!!!

Cary smile

Re: Is it possible to upload files to Amazon using html5 and html4?

S3 will not host anything but static content so I do not believe PHP or C# files can be used in that scenario...

Right it should be static, you should serve plupload from prepared html page.

By the way, I use flajaxian too, and that uses a crossdomain.xml file I keep in my bucket. I am also wondering why that is not a cross-domain request....

Not sure what you are asking here. Flash and SilverLight can do cross-domain requests due to the mentioned crossdomain.xml, which is placed on destination domain. HTML5 uses different technique and it is not currently supported by Amazon S3.

BTW, are you away of any security implications for hosting the plupload control on S3 versus a web server?

What kind of security implications? If you are very concerned with security you probably shouldn't host plupload on S3. Just go with Flash and SilverLight, or upload indirectly using mediator server-side uploader on your side.

Re: Is it possible to upload files to Amazon using html5 and html4?

Hi!

Thanks so much for the quick response.

I do wish to try as per, "Actually you could try and test the same approach for Plupload - try to serve it directly from S3 and it should work. There is no other workaround around this currently (for HTML5 runtime I mean)."

Now can you give a sample for the HTML5 runtime as per above. I truly have no clue how to try this out. I only wish to use for html5, so let's forget about all other runtimes, and any security issues. I just need to understand how to test your hypothesis that it should work for the above quote...

Thanks again!

Cary

Re: Is it possible to upload files to Amazon using html5 and html4?

I just reread this entire thread as I know I am missing something profound yet simple; the horror! smile)

However I just want to clarify that the jquery-html5-plugin does indeed use 'PUT", and does indeed have progress....

I believe this could revolutionize the PLUpload control in the cloud.... And we see now, more than ever, the cloud is the end all and be all; it is the future!

Help smile)

Thanks Again!

Cary

Re: Is it possible to upload files to Amazon using html5 and html4?

Cary, just put bundled s3.php on some web-server, load it in browser, then view the source, copy it and you will have a template for the html file you would need to place on S3 to try out my hypothesis smile But of course be sure to populate sample s3.php file with your own S3 details first and, perhaps, fix URIs for styles and scripts, and do not forget to put scripts (at least) on S3 as well. Consider bundled s3.php as a generator of static s3 uploader templates.

As far as I see in jquery-html5-plugin's source they use POST by default. What makes you think it is PUT, and what is all that latest post of yours all about actually? Hmm...

Re: Is it possible to upload files to Amazon using html5 and html4?

Hi Davit!!

Thanks for all your assistance. I am going to do my level best to try out your suggestions right now. I did not think I could run a php file out of S3. My php experience is on par with my astronaut experience wink)

As to the post versus put with jquery-html5-upload plugin....

It is indeed using put.

Here is the thread and below is my implementation which actually works smile)

While tracing I also noticed the default of POST but I believe the thing to keep in mind here is that it was not originally designed to work with S3. That is a recent development and the individual who retrofitted it for S3 implemented it via PUT as per.....

http://code.google.com/p/jquery-html5-u … tail?id=12

Excerpt:

DMagon: yes, I have it working on S3, you can see a sample at http://upload.attik.com/html5_upload/example.html

If you look at the source, you can see how I've set things to work, including setting the **method to PUT** and sendBoundary to false (if you send boundaries they will be in the file).
S3 settings: you need to put these files in a bucket that has public-write access. Of course if you set both public write and public read, anyone can use your S3 bucket for their own file storage, so I would discourage that.
NOTE: I plan to submit a patch to allow more flexibility in the headers sent. I have added a header at line 124 (x-amz-acl: bucket-owner-full-control) that gives the bucket owner full control over the file. Sometimes AWS can lock you out of doing anything with the file but deleting it if you don't do this.

Implementation: notice 'PUT' for method attribute value. I believe this is required for progress bar to function....

<script type="text/javascript">

Re: Is it possible to upload files to Amazon using html5 and html4?

Hi Davit,

Interesting results. I created a new bucket for this new experiment.
I put the php, html, and all support files therein.

The uploader loads just fine.

I drag and bunch of images onto the uploader and then click start upload.

The progress bar jumps into action and it accurately loops through the files and shows the total size. Perhaps it goes too fast... Just not sure what I should be looking for here.

I then click a button <input type="submit" value="Here goes nothin!"/>


The browser URL changes to the correct address of the s3.php so I think my paths are fine.

Fiddler shows and http 405 error as per (which is also rendered with the s3.php):

<Error>
<Code>MethodNotAllowed</Code>

<Message>
The specified method is not allowed against this resource.
</Message>
<ResourceType>OBJECT</ResourceType>
<Method>POST</Method>
<RequestId>AA599DD8D364C1DB</RequestId>

<HostId>
eAgROVNQ3AoHwr6Qmr9u9JnmccjLtxD49oESITcKh75PgahpjVJdqd2XfLrSMttp
</HostId>
</Error>


Due to my unfamiliarity with PHP and this process I am relying upon your expertise.

I am including my html & php pages below to hopefully determine whether or not this is truly possible. I am stuck and do not understand whether what I am trying to do is possible. Fiddler does seem to register all the files I want to upload it's just this 405 error which seems to imply it will not allow the post.

Also the inside of the s3.php PLUpload supplies seems geared towards the silverlight/flash cross domain methodology so... well I am just not sure what is going on and if I am missing something or this is just not allowed... smile

I appreciate all your help Davit!

Thanks,

Cary

Re: Is it possible to upload files to Amazon using html5 and html4?

Cary, you are doing it all wrong smile And actually it'is so much wrong that I just have no clue where to start to put you on the right path...

You should not place php on s3, it won't work there (does it?), but you should place a result of loading php in the browser (which is pure html). If that makes no sense to you, I'm afraid I can't help you.

I will think of simple example in later release.

If you want to see your issue fixed, do not report it here, do it on - GitHub.

Re: Is it possible to upload files to Amazon using html5 and html4?

Hi Davit,

I am afraid my understanding, as explained of PHP is non-existent. I see that my ignorance is php is something that you cannot walk me through. I appreciate you taking the time to respond to my posts.

However, I do think if it were a case of it being simple as you say, in other words it should just work as is, you would be able to create a sample in no time at all.

I am sure this could only reflect well on your product smile

But I see I will regrettably have to abandon my PLUpload plans for now.

Thanks anyway sir. I appreciate all your efforts!

Re: Is it possible to upload files to Amazon using html5 and html4?

Cary, it's not exactly that simple. It is meant that after you prepare that html you will undertake some more manipulations, experiment a bit, here, there. I just do not have step-by step guide for this at the moment.

If you want to see your issue fixed, do not report it here, do it on - GitHub.

I understand completely Davit. I am experimenting with outsourcing this job and this thread might help jquery/php experts to avoid having to merge the jquery-html5-uploader code with your html5 script. At any rate it has been educational and you always respond quickly! Thanks again sir!

Re: Is it possible to upload files to Amazon using html5 and html4?

Hi, I've just started using Plupload, has anyone got any further in making this work with html5?

I've got direct to s3 with html4 if it helps anyone, what you need to do is point success_access_redirect to a path on your server, content can be anything, it just needs to returns a 200 for plupload to see...

multipart_params:{
  'key':'etc..',
  'success_action_redirect':'http://mydomain.com/success.html'
}

If your using policyfiles, you need to add to that also:
['starts-with', '$success_action_redirect', '']

Tested with safari/chrome.. not sure about windows & IE.

@Anthony Amazon itself should make the next step I guess.

Now about 'Yes' (not tested)

Theoretically one could host uploader form right in the bucket, inside specially constructed html file. It should work (but no chunking, which means no progress for html5). Anyone eager to try? smile

For reference, I managed to do this through the following steps:

1. Put plupload and dependencies in the bucket.
2. Put an iframe on the upload page, by default pointing to a standard ajax loading animation. Also put an ajax request to a server page, executed when the document is ready.
3. In the server page script, create a html document containing the uploader and the signed upload request (as done in the S3.php example).
4. Upload the html doc to the bucket (I used undesigned's lightweight S3 PHP class).
5. Create a signed url to the new html document and return it to the client.
6. Navigate the iframe to the url.
7. The uploader loads from the bucket and you will be able to upload using the html5 runtime.

I had no problem to upload a 5 GB file, except for the slow speed, around 9 Mbit/s up compared to 50 Mbit/s down. I guess implementing the the Amazon S3 multipart upload feature would help.

Is this something the Plupload team will look into?
