[disword]

Issue

Short description

I can't find these info. Could you tell me how to get it?

Environment

[] Operating system and version:Mac
[] Java version:openjdk version "1.8.0_151"
[] Red5 version:1.0.9 release

Expected behavior

get query string like paramsOne or user1

Actual behavior

I can't find any info about query string like paramsOne or user1.

Steps to reproduce

1.use my custom ApplicationAdapter and registerStreamPublishSecurity
public boolean isPublishAllowed(IScope iScope, String str1, String str2) {
Set attributeNames = iScope.getAttributeNames();
for (String attributeName : attributeNames) {
log.info("attributeName = " + attributeName);
}
log.info("str1 = " + str1);
log.info("str2 = " + str2);
}
2. publish a rtmp stream: rtmp://127.0.0.1:1935/live/aaa?paramsOne=user1

3. to get the params=aaa in my ApplicationAdapter in connect(IConnection conn, IScope scope, Object[] params)
   log.info("Connection params: {}", conn.getConnectParams());
   log.info("Connection attributes: {}", conn.getAttributes());
   if (params != null) {
   log.info("Params: {}", Arrays.toString(params));
   }
