基于@AmitJoshi的其他答案；我现在可以回答我的问题:

Based on other answer from @AmitJoshi; I can now answer my question:

这是JavaScript函数:

Here is the JavaScript function:

function GenerateUidFromGuid(){
   var guid = uuid.v4();                         //Generate UUID using node-uuid *) package or some other similar package
   var guidBytes = `0${guid.replace(/-/g, "")}`; //add prefix 0 and remove `-`
   var bigInteger = bigInt(guidBytes,16);        //As big integer are not still in all browser supported I use BigInteger **) packaged to parse the integer with base 16 from uuid string
   return `2.25.${bigInteger.toString()}`;       //Output the previus parsed integer as string by adding `2.25.` as prefix
}
