报错内容：
Unable to parse Build/RobotTest.framework.js.gz! This can happen if build compression
was enabled but web server hosting the content was misconfigured to not serve the file
with HTTP Response Header "Content-Encoding: gzip" present. Check browser
Console and Devtools Network tab to debug.
解决办法：
Edit -> Project Settings -> Player -> WebGL settings -> Publishing Settings
勾选Decompression Fallback
