yyh357 只需要修改 [{"Name":"derp","RegionID":900,"HostName":"xxxxxxx.derps.link","DERPPort":xxxx,"STUNPort":xxxx,"InsecureForTests":true}] 的部分，添加到这个位置。比如
"derpMap":{"OmitDefaultRegions":false,"Regions":{"900":{"RegionID":900,"RegionCode":"cn1-1143","RegionName":"derp","Nodes":[{"Name":"derp","RegionID":900,"HostName":"xxxxxxx.derps.link","DERPPort":xxxx,"STUNPort":xxxx,"InsecureForTests":true}]，[{"Name":"derp","RegionID":901,"HostName":"xxxxxxx.derps.link","DERPPort":xxxx,"STUNPort":xxxx,"InsecureForTests":true}]}}},
