1、I used sentinel version 1.7.2
2、configured it in the. YML file sentinel: datasource: authority: nacos: server-addr: 127.0.0.1:8848 dataId: ${spring.application.name}-authority-rules rule-type: authority data-type: json
3、Add profile in Nacos named hszsd-ds-crm-service-authority-rules [ { "resource": "/getUserInfo", "limitApp": "172.16.201.214", "strategy": 1 } ]
4、Check the source code static boolean passCheck(AuthorityRule rule, Context context) { String requester = context.getOrigin();
// Empty origin or empty limitApp will pass.
if (StringUtil.isEmpty(requester) || StringUtil.isEmpty(rule.getLimitApp())) {
return true;
}
// Do exact match with origin name.
int pos = rule.getLimitApp().indexOf(requester);
boolean contain = pos > -1;
if (contain) {
boolean exactlyMatch = false;
String[] appArray = rule.getLimitApp().split(",");
for (String app : appArray) {
if (requester.equals(app)) {
exactlyMatch = true;
break;
}
}
contain = exactlyMatch;
}
int strategy = rule.getStrategy();
if (strategy == RuleConstant.AUTHORITY_BLACK && contain) {
return false;
}
if (strategy == RuleConstant.AUTHORITY_WHITE && !contain) {
return false;
}
return true;
}
