看api文档就可以了，粘两个例子吧，如果配置了域名，可以请求域名

[root@node ~]# vi zabbix_login.api
curl -XPOST -H "Content-Type: application/json-rpc" -d '
{"jsonrpc": "2.0","method": "user.login","params": {"user": "Admin","password": "zabbix"},"id": 1,"auth": null
}' http://serverIP/zabbix/api_jsonrpc.php
[root@node ~]# sh zabbix.api
{"jsonrpc":"2.0","result":"8b16faa2f8c9d02f0a6694d667774bac","id":1}

拿到用户用户认证令牌后，就可以使用令牌来操作了

[root@node ~]# vi zabbix_gethost.apicurl -XPOST -H "Content-Type: application/json-rpc" -d '
{"jsonrpc": "2.0","method": "host.get","params": {"output": ["hostid","host"],"selectInterfaces": ["interfaceid","ip"]},"id": 2,"auth": "8b16faa2f8c9d02f0a6694d667774bac"
}
' http://serverIP/zabbix/api_jsonrpc.php
[root@node ~]# sh zabbix_gethost.api
{"jsonrpc":"2.0","result":[{"hostid":"10442","host":"zbx-agent","interfaces":[{"interfaceid":"11","ip":"x.x.x.x"}]}],"id":2}
