How to send much binary data from JavaScript to C++

[somebodyy]

Hello,

what is the recommended way to send much (multiple MB) of binary data from JavaScript to C++?

I thought of the filesystem api, but the resulting filenames etc. are obfuscated.

From the GeneralUsage i can see that I can send requests like this:

Code: Select all

var request_id = window.cefQuery({
    request: 'my_request',
    persistent: false,
    onSuccess: function(response) {},
    onFailure: function(error_code, error_message) {}
});


However, for all I found, the request can only be a String. Is it a good idea to base64 multiple mb data and sent it as request?
Because that sounds like abusing the query mechanism.

Cheers

It's probably best to use the network stack. For example, send the data using XMLHttpRequest and handle it via a custom request handler. See the GeneralUsage wiki page for related documentation.

Thanks, I didn't even think of this I will try to implement it like that

Just don't make the mistake I did :

If you're using POST for that XmlHttpRequest, the custom handler needs to be http / https: and a subdomain like myapp.myapp.com, NOT a custom prefix like mydata://domain/

Hah, thats exactly the same mistake I did. I think this should be made a little more visible in the General Usage document

Documentation updated.. hopefully the warning is visible enough now
