Viewing Examples​

How to enable viewing:

  • Method 1: Each logger has a default output level on creation, default warn — only warn and error are shown
  • Method 2: Append __logConf__ to the URL, for example:
https://lowcode-engine.cn/demo/demo-general/index.html?__logConf__=warn
// Enable warn and error for all bizNames

https://lowcode-engine.cn/demo/demo-general/index.html?__logConf__=debug
// Enable debug, log, info, warn, and error for all bizNames

https://lowcode-engine.cn/demo/demo-general/index.html?__logConf__=log
// Enable log, info, warn, and error for all bizNames

https://lowcode-engine.cn/demo/demo-general/index.html?__logConf__=warn|*
// Same as __logConf__=warn

https://lowcode-engine.cn/demo/demo-general/index.html?__logConf__=warn|bizName
// Enable debug, log, info, warn, and error for bizName

https://lowcode-engine.cn/demo/demo-general/index.html?__logConf__=warn|partOfBizName
// Enable debug, log, info, warn, and error for bizNames matching '%partOfBizName%'
