Sending authenticated sessionID cookie from browser to notifyUser

[doraintech]

Hi,

thanks for the reply.

I set <use_protected_js>Y</use_protected_js> and <forward_cookies>Y</forward_cookies>

but still in the request i only see the following:

{ id: '40000014605500b77',
verb: 'notifyUser',
userName: null,
userPassword: null,
headers:
{ 'content-type': 'application/x-www-form-urlencoded; charset=UTF-8',
'cache-control': 'no-cache',
connection: 'keep-alive',
host: 'localhost',
'accept-language': 'en-US,en;q=0.5',
accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'content-length': '151',
origin: 'https://localhost:4433',
'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:29.0) Gecko/20100101 Firefox/29.0',
'accept-encoding': 'gzip, deflate',
referer: 'https://localhost:4433/view1',
pragma: 'no-cache',
REQUEST_ID: '16' } }

Here is my notify user method:

metadataProvider.on('notifyUser', function(request, response){

console.log(request);

});

and here is the adapters config:

<metadata_provider>
<adapter_class>com.lightstreamer.adapters.remote.m etadata.RobustNetworkedMetadataProvider</adapter_class>
<classloader>log-enabled</classloader>
<param name="request_reply_port">6662</param>
<param name="timeout">36000000</param>
</metadata_provider>


Is there something else that I need to do?

Thanks for the help.

Hi,

It might depend on the browser in use; be sure to call lightstreamerClientInstance.connectionOptions.setC ookieHandlingRequired(true) on the client
See
http://www.lightstreamer.com/docs/cl...ndlingRequired
and
https://docs.google.com/a/lightstrea...rive_web#gid=1


If still in trouble verify that the cookie is sent by the browser (check the creatre_session.js request) and get back to us.

that did the trick, thanks for the help!

Actually, that fixed one problem and exposed another one. I now have the required cookies, and I parse them and use the result to perform a lookup in a database which is an async call. Is it OK to call async code inside the notifyUser method? It seems that this is causing an issue currently as then I change the method body to simply:

response.success(100000000,false);

... everything works just fine.

However then I call response.success(100000000,false); from the database callback function the LSClient will no longer connect.

What is the recommended approach here?

Have looked into this further - when client.connectionOptions.setCookieHandlingRequired (true); is set by the client the request headers that are sent to the notifyUser method are different. For example:

When client.connectionOptions.setCookieHandlingRequired is set to true:

headers:
{ cookie: 'connect.sid=s%3A8RiLRECNKkGGSJOQnKGdGizY.iqYm2IPN gzJph7Qk%2BrG1pEqktnlm0KVLtpXEVZ5L2Yw; XSRF-TOKEN=jhIQq6AYLGxE2DrjxiK8L1zg67RfV0eaCt0N0%3D',
connection: 'keep-alive',
host: 'localhost',
'accept-language': 'en-US,en;q=0.5',
accept: '*/*',
'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:29.0) Gecko/20100101 Firefox/29.0',
'accept-encoding': 'gzip, deflate',
referer: 'https://localhost:4433/view1',
REQUEST_ID: '7' } }

.... and when client.connectionOptions.setCookieHandlingRequired is set to false:

headers:
{ 'content-type': 'application/x-www-form-urlencoded; charset=UTF-8',
'cache-control': 'no-cache',
connection: 'keep-alive',
host: 'localhost',
'accept-language': 'en-US,en;q=0.5',
accept: 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'content-length': '147',
origin: 'https://localhost:4433',
'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:29.0) Gecko/20100101 Firefox/29.0',
'accept-encoding': 'gzip, deflate',
referer: 'https://localhost:4433/view1',
pragma: 'no-cache',
REQUEST_ID: '4' } }

As we can see above the headers are different by more than just the cookie. For example when setCookieHandlingRequired is true the origin field is not specified.

When setCookieHandlingRequired is true my LS client can't connect; I have a feeling that the problem is related to the differences mentioned above.

Please can you advise?

Thanks.
