No observers in list when running server.observable.js

[xiaoyu3x]

I got the following information when running server.observable.js and client.observe.js.
Client outputs:

But sever always continuously outputs "Sensor data has changed,No observers in list "

I added console.log into iotivity.OCCreateResource(), but I found no information output.

46 is the code for a denied request. As of the latest iotivity-node, security is enabled. Therefore, for successful communication between the client and the server, you need to create oic_svr_db.dat files for both the client and the server. The process and links to sample files can be found at https://wiki.iotivity.org/security_resource_manager You create the files by processing a JSON file using json2cbor, a tool provided by iotivity. You can build the tool as part of iotivity with scons SECURED=1 resource/csdk/security/tool You need to place the resulting .dat files into a subdirectory of ~/.iotivity-node The name of the subdirectory is the sha256sum of the absolute path of the JS file. So, for a file named "/home/user/project/server.ocf.js", you can obtain the sha256sum as follows: echo -n '/home/user/project/server.ocf.js' | sha256sum This yields ff85509781006eb0da9c4e278e1a685d9b55e09bb03f4115d07fbe6a92d4569e - Thus, you would mkdir -p ~/.iotivity-node/ff85509781006eb0da9c4e278e1a685d9b55e09bb03f4115d07fbe6a92d4569e and cp oic_svr_db.dat ~/.iotivity-node/ff85509781006eb0da9c4e278e1a685d9b55e09bb03f4115d07fbe6a92d4569e After repeating this process for both the client and the server, and having made sure that the files have the correct contents, you can launch the server. https://github.com/otcshare/iotivity-node/blob/master/SECURITY.md also contains these instructions. There is a second approach to creating the .dat files. If you take this approach, you provide the server with a sample .dat file, after which you provision it using the iotivity provisioning client example tool. This approach is described here: https://github.com/otcshare/iotivity-node/blob/master/js/README.md

hi, @gabrielschulhof
Why not found 'provisioningclient'(step 5 in README.md) for me after run scons SECURED=1 resource/csdk/security/tool, and I can't get 'oic_svr_db_client.dat'.

Please help to me.

[gabrielschulhof]

It's in out/<platform>/<architecture>/release/resource/csdk/security/tool ... <platform> means your platform, like "linux", or "win32", and <architecture> means your processor architecture, like "x86_64".

hi, @gabrielschulhof
I still can't find oic_svr_db_client.dat and the following is my folder:

What pre-condition I need?

This issue is reproduced with commit 35461e8

[yannS2016]

was this ever resolved?

[gabrielschulhof]

@yannS2016 I'm having trouble reproducing this issue. If your access control works properly, you will not get status 46. Are you seeing this too?
