    javascript - Send udp packet from chrome - Stack Overflow

    programmeradmin10浏览0评论

    Researching on the internet ( How to send udp to udp node.js server?, JavaScript WebSockets with UDP?) I have found that it is not possible to send udp packets with javascript.

    On the other hand some pages claim that chrome browser is able to do so. For example the link:

    claims that google chrome is able to send udp packets. Maybe I am doing something wrong. If it is true that chrome can send udp packets I will appreciate if someone can post a hello world example. I have tried the example from the link I showed and it does not work. Maybe I am doing something wrong.

    • 3 From that page: "Chrome Canary now has support for raw TCP and UDP sockets in its ‘experimental’ APIs. These features are only available for extensions and, although documented, are hidden for the moment". What have you tried that did not work? – Bergi Commented Dec 20, 2012 at 3:49
    • You are right I should paid more atention when reading instead of jumping straight to the code. Thanks for pointing that out. I guess that should be an answer – Tono Nam Commented Dec 20, 2012 at 5:11

    Reset to default 5

    From the linked page:

    Chrome Canary now has support for raw TCP and UDP sockets in its ‘experimental’ APIs. These features are only available for extensions and, although documented, are hidden for the moment.

    So, develop an extension and it should work. Actually, that article from May '12 seems to be outdated as the chrome.socket module now has lost its experimental status. For the HelloWorld, you might check out their udp sample which is linked from the official pages.
