在linux shell環境下直接調用就可以，根據官網所述：在訪問Zabbix中的任何數據之前，你需要登錄并獲取身份驗證令牌。這可以使用該 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.php
HTTP/1.1 200 OK

X-Powered-By: PHP/5.6.36
Access-Control-Allow-Origin: *
Access-Control-Allow-Headers: Content-Type
Access-Control-Allow-Methods: POST

Content-Length: 68
Content-Type: application/json
{"jsonrpc":"2.0","result":"77bfe44db3f5c016477110c5748ac3e1","id":0}

根據官網所述，返回了用戶身份驗證令牌"77bfe44db3f5c016477110c5748ac3e1"，后面所有的api請求都需要帶著它。

依葫蘆畫瓢又查詢了一個，這次帶著上面的身份驗證令牌：

[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.p

{"jsonrpc":"2.0","result":[{"hostid":"10084","host":"Zabbix server","interfaces":[{"ip":"127.0.0.1"}]}],"id":4}

返回了主機名Zabbix server，主機Ip 127.0.0.1

實際上，API怎么用還是要以官網文檔為準，比如apiinfo.version，官網寫的很清楚：此方法可用于未經身份驗證的用戶，必須在發送 JSON-RPC 請求中不加“auth”參數的情況下調用。

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.php

Access-Control-Max-Age: 1000
Content-Length: 42
Content-Type: application/json
{"jsonrpc":"2.0","result":"3.4.14","id":5}

顯示目標主機的Zabbix API 版本是3.4.14
