一、动态规则API命令

使用API模式命令需要在客户端引入sentinel-transport-simple-http模块。

1.支持的API命令

http://x.x.x.x:8719/api 备注：get all available command handlers

[{
    "url": "/cnode",
    "desc": "get clusterNode metrics by id, request param: id={resourceName}"
}, {
    "url": "/origin",
    "desc": "get origin clusterNode by id, request param: id={resourceName}"
}, {
    "url": "/tree",
    "desc": "get metrics in tree mode, use id to specify detailed tree root"
}, {
    "url": "/version",
    "desc": "get sentinel version"
}, {
    "url": "/clusterNode",
    "desc": "get all clusterNode VO, use type=notZero to ignore those nodes with totalRequest <=0"
}, {
    "url": "/basicInfo",
    "desc": "get sentinel config info"
}, {
    "url": "/jsonTree",
    "desc": "get tree node VO start from root node"
}, {
    "url": "/getClusterMode",
    "desc": "get cluster mode status"
}, {
    "url": "/metric",
    "desc": "get and aggregate metrics, accept param: startTime={startTime}&endTime={endTime}&maxLines={maxLines}&identify={resourceName}"
}, {
    "url": "/setClusterMode",
    "desc": "set cluster mode, accept param: mode={0|1} 0:client mode 1:server mode"
}, {
    "url": "/systemStatus",
    "desc": "get system status"
}, {
    "url": "/getSwitch",
    "desc": "get sentinel switch status"
}, {
    "url": "/getRules",
    "desc": "get all active rules by type, request param: type={ruleType}"
}, {
    "url": "/api",
    "desc": "get all available command handlers"
}, {
    "url": "/setRules",
    "desc": "modify the rules, accept param: type={ruleType}&data={ruleJson}"
}, {
    "url": "/setSwitch",
    "desc": "set sentinel switch, accept param: value={true|false}"
}, {
    "url": "/clusterNodeById",
    "desc": "get clusterNode VO by id, request param: id={resourceName}"
}]

2.基本信息命令
