在linux shell环境下直接调用就可以，根据官网所述：在访问Zabbix中的任何数据之前，你需要登录并获取身份验证令牌。这可以使用该 user.login 方法完成。

[root@localhost ~]# curl -i -X POST -H "Content-Type: application/json" -d "{"jsonrpc": "2.0","method":"user.login","params":{"user":"Admin","password":"zabbix"},"auth": null,"id":0}" http://192.168.149.129/zabbix/api_jsonrpc.phpHTTP/1.1 200 OKDate: Fri, 26 Oct 2018 07:46:05 GMTServer: Apache/2.4.6 (CentOS) PHP/5.6.36X-Powered-By: PHP/5.6.36Access-Control-Allow-Origin: *Access-Control-Allow-Headers: Content-TypeAccess-Control-Allow-Methods: POSTAccess-Control-Max-Age: 1000Content-Length: 68Content-Type: application/json{"jsonrpc":"2.0","result":"77bfe44db3f5c016477110c5748ac3e1","id":0}

根据官网所述，返回了用户身份验证令牌"77bfe44db3f5c016477110c5748ac3e1"，后面所有的api请求都需要带着它。

依葫芦画瓢又查询了一个，这次带着上面的身份验证令牌：

[root@localhost ~]# curl -i -X POST -H "Content-Type: application/json" -d "{"jsonrpc": "2.0","method":"host.get","params":{"output":["host"],"selectInterfaces":["ip"]},"auth": "77bfe44db3f5c016477110c5748ac3e1","id":4}" http://192.168.149.129/zabbix/api_jsonrpc.phpHTTP/1.1 200 OKDate: Fri, 26 Oct 2018 08:17:23 GMTServer: Apache/2.4.6 (CentOS) PHP/5.6.36X-Powered-By: PHP/5.6.36Access-Control-Allow-Origin: *Access-Control-Allow-Headers: Content-TypeAccess-Control-Allow-Methods: POSTAccess-Control-Max-Age: 1000Content-Length: 111Content-Type: application/json{"jsonrpc":"2.0","result":[{"hostid":"10084","host":"Zabbix server","interfaces":[{"ip":"127.0.0.1"}]}],"id":4}

返回了主机名Zabbix server，主机Ip 127.0.0.1

实际上，API怎么用还是要以官网文档为准，比如apiinfo.version，官网写的很清楚：此方法可用于未经身份验证的用户，必须在发送 JSON-RPC 请求中不加“auth”参数的情况下调用。

示例如下：

[root@localhost ~]# curl -i -X POST -H "Content-Type: application/json" -d "{"jsonrpc": "2.0","method":"apiinfo.version","params":[],"id":5}" http://192.168.149.129/zabbix/api_jsonrpc.phpHTTP/1.1 200 OKDate: Fri, 26 Oct 2018 08:40:17 GMTServer: Apache/2.4.6 (CentOS) PHP/5.6.36X-Powered-By: PHP/5.6.36Access-Control-Allow-Origin: *Access-Control-Allow-Headers: Content-TypeAccess-Control-Allow-Methods: POSTAccess-Control-Max-Age: 1000Content-Length: 42Content-Type: application/json{"jsonrpc":"2.0","result":"3.4.14","id":5}

显示目标主机的Zabbix API 版本是3.4.14
