Examples about node-opcua HOT 7 CLOSED

Hey, Thank you for your interest,
The project is pretty much at its early stage. At this time, a client can only connect to a server ,sending the HEL message and receiving the ACK message.
The next steps are to implement GetEndPoints and OpenSecureChannel/CloseSecureChannel.

Please feel free to suggest pull request or contribute, The task is quite enormous and as GitHub moto says : let's "Build Better software, Together").

Hey, right now I'm still trying to get it to work, it will not install via NPM on my Windows machine since the x509 module cannot be installed, haven't tried on my Linux machine, it gives the following error:

317 error [email protected] install: node-gyp rebuild
317 error Exit status 1
318 error Failed at the [email protected] install script.
318 error This is most likely a problem with the x509 package,
318 error not with npm itself.
318 error Tell the author that this fails on your system:
318 error node-gyp rebuild
318 error You can get their info via:
318 error npm owner ls x509
318 error There is likely additional logging output above.
319 error System Windows_NT 6.2.9200
320 error command "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js" "install" "node-opcua" "--python"
321 error cwd C:\Users\JT\Documents\Projects\Node-OPC
322 error node -v v0.10.24
323 error npm -v 1.3.21
324 error code ELIFECYCLE
325 verbose exit [ 1, true ]

Why does it need to the x509 module? What certificates are needed to parse?

I tried simply downloading the repo, placing it in the node_modules folder and calling:

var opcua = require('node-opcua');

from the top-level, without success:

ERROR: Cannot find module "node-opcua"

Is it being exported as a standard Nodejs module or are the exports not set up yet?

Thanks in advance

from node-opcua.

Update: Added exports file to make it incudeable from top-level using:

var opcua = require('node-opcua');

Only includes the lib\nodeopcua.js script at the moment:

It looks like the x509 npm module seems broken and not supported on windows.
I have removed dependencies to the x509 module and replaced it with ursa and rsa-stream.

Hi Jeppe,
I have incorporated your fix to make it work as a npm package.
I have also now provided an example in the README and in this little project node-opcua-sample
Let me know how it goes on your side...

Hi Etienne,
Thanks for all your great work on node-opcua. I'm just starting to experiment with it. I'd like to connect to a server that requires a username and password.

I see opcua-client.js (line 523) has OPCUAClient.prototype._activateSession() that creates a new AnonymousIdentityToken. I was wondering where the best place might be to modify this code. Options I came up with include:

• Not modifying your code at all. In the myfirstclient.js, I could replace _activateSession() with a new one that creates a different IdentityToken. But I didn't think that public code should be modifying functions starting with _
• I could leave your code alone, and replace the createSession() function with one that doesn't call _activateSession(). But that seems to be making too much work for myself.
• I could modify your code so that _activateSession() doesn't always create a new AnonymousIdentityToken. Instead, it could have a userIdentityToken field which is initialized as an AnonymousIdentityToken, but my user code could overwrite that field.
• Having a prototype.CreateUserIdentityToken() function that could be replaced by user code.
• Various others.

Do you have a preference?

Hi John,
I have modified createSession so we can now pass an optional userIdentityToken ,
see abfbee6 and https://github.com/erossignon/node-opcua/blob/master/test/test_opcua_ClientServer_UserNameIdentityToken.js#L54
