Access project or peoject UI display blank out, request page like "http://localhost:8080/lamp_demo/c1"

[wisdomleo]

Dear Bambooww,

When I access peoject, it will open new window in browser, request url like "http://localhost:8080/lamp_demo/c1", but display blank out, see below:

I checked the released web request, shows that it redirected to ".../hmi_ajax.jsp?op=load&path=test/hmi1", I tried to debug it and find what's wrong with it, but nothing was found.

I don't know how it will go while requesting "localhost:8080/ ui_of_proj_path", is it will request "web/ROOT/index.jsp" at first ? then redirected to the special page? or ? I don't know.

Best Regards,
Leo Ma

I checked the logic of PrjFilter.java, still don't know how to fix it and have no idea about it. Coule you please finger out what does it happen when I access the project path? Thanks a lot!!!

Filter intercepts the request and redirects it to the specific JSP path for execution. Please refer to the directory hierarchy of the release version.

Also, let's first understand the Java web filter mechanism

Because this URL is usually accessed in application scenarios such as HMI display and RESTful interface. And /web/admin/ webapp has its own permission checker.

For ROOT, relevant customized permissions can be used for external use

Looks like the required access token or others is missing, while checking PlugAuth, it returns blank page and only shows "no read permission 333" which I configured in the file "config.xml", see below:

Now I am confused about two:
1. the PlugAuth, why display "no read permission 333" while copying all the data folder from "*.zip" to source code folder:

2. If passed the auth check, which java file parse the config peoject( 组态项目 )， and response the UI access page?

Please do not run IoT-Tree under Tomcat, this is not a web app. On the contrary, Tomcat is just an internal basic web container.

I knew it, the executable file "iottree_win_panel.exe" could start one backstage service, and access the url "localhost:9090/admin" in browser is fine.

But how to build project & artifacts, how to change the source code and debugging? Cause I use IDEA as the java developement environment, I configurated the "Tomcate Server" as Run/Debug component, and deploy the webapps to apache tomcat install path "%tomcat_path%\bin". I also deployed the iottree server to one "personal server", and could upgrade my changes and access by ip address.

I'd like to develope personalized function base on iottree. Thas's all.

By the way, I am curious about that how many developers have maintained or are maintaining the iottree since the begining? I noticed the first commit is "bamboowwcommitted
on May 11, 2021".

You can refer to the iot-tree.bat in the release version and configure the IDE environment in reverse
