這篇文檔總結一下我初步學習Openstack的api，而且趁這個機會學習一下Firefox的restclient客戶端。python

 

1、使用curl命名來使用openstack的apijson

 

固然，首先你得有個openstack的環境，我是本身搭建的kilo，咱們先用curl來使用api，注意本身改一下ip還有用戶名和密碼，下面這個命令就會獲得一個令牌(token)來使用，之後調用api就須要使用這個令牌。windows

curl -k -X 'POST' -v http://controller_ip:5000/v2.0/tokens -d '{"auth":{"passwordCredentials":{"username": "ADMIN", "password":"MY_PASSWORD"}}}' -H 'Content-type: application/json' | python -mjson.tool

這樣後會獲得以下的json數據api

{
    "access": {
        "metadata": {
            "is_admin": 0,
            "roles": []
        },
        "serviceCatalog": [],
        "token": {
            "audit_ids": [
                "WPon6i60TamUfqcsPV2oVg"
            ],
            "expires": "2015-11-06T11:19:19Z",
            "id": "bc422dc370324535a64699640f50a3ab",//這個id就是令牌(token)
            "issued_at": "2015-11-06T10:19:19.559266"
        },
        "user": {
            "id": "9c20d9fe21a14741ac1486b2db058bd5",
            "name": "admin",
            "roles": [],
            "roles_links": [],
            "username": "admin"
        }
    }
}

 

下面獲得這個用戶的全部項目(tenant)，注意下面的token就是剛剛獲得的那個令牌瀏覽器

curl -X 'GET' -H  "X-Auth-Token:bc422dc370324535a64699640f50a3ab" -v http://controller_ip:5000/v2.0/tenants | python -mjson.tool

 

這裏面獲得這個用戶的項目(tenant)app

{
    "tenants": [
        {
            "description": null,
            "enabled": true,
            "id": "92afd13a680645c191a2aab7422a7a3b",
            "name": "AIM"
        },
        {
            "description": null,
            "enabled": true,
            "id": "b3457999de4d4add99e89f4f299f5857",
            "name": "ECM"
        },
        {
            "description": "Admin Project",
            "enabled": true,
            "id": "de8f43bfe4244a1aa315a70a43248d60",
            "name": "admin"
        },
        {
            "description": null,
            "enabled": true,
            "id": "f3c1015ff67e4cd18b022b9b51eb1123",
            "name": "IM"
        },
        {
            "description": null,
            "enabled": true,
            "id": "fae79b8f91b944b985d2b35373cf9bb2",
            "name": "Commerce"
        }
    ],
    "tenants_links": []
}

能夠看到我這裏ADMIN用戶總共有5個tenant，咱們選取一個便可，就選取名爲admin的項目，id看到爲de8f43bfe4244a1aa315a70a43248d60curl

 

接下來咱們去一個項目(tenant)看看它的虛擬機、等信息。ide

 

首先須要獲得這個tenant的令牌信息，注意這個token和上面的那個不同

curl -k -X 'POST' -v http://controller_ip:5000/v2.0/tokens -d '{"auth":{"passwordCredentials":{"username": "ADMIN", "password":"MY_PASSWORD"},"tenantId":"de8f43bfe4244a1aa315a70a43248d60"}}' -H 'Content-type: application/json' | python -mjson.tool

注意這裏看到用戶名和密碼仍是和以前同樣，可是多了一個tenantId的字段，這裏說明了咱們須要的是ADMIN用戶下的這個項目的令牌，獲得以下信息：

{
    "access": {
        "metadata": {
            "is_admin": 0,
            "roles": [
                "cf87d1b66b044cdd94972d72d6e4d474"
            ]
        },
        "serviceCatalog": [
            {
                "endpoints": [
                    {
                        "adminURL": "http://controller:9292",
                        "id": "5f892fde3a2241c989355cdd6beea4b5",
                        "internalURL": "http://controller:9292",
                        "publicURL": "http://controller:9292",
                        "region": "RegionOne"
                    }
                ],
                "endpoints_links": [],
                "name": "glance",
                "type": "image"
            },
            {
                "endpoints": [
                    {
                        "adminURL": "http://controller:8774/v2/de8f43bfe4244a1aa315a70a43248d60",
                        "id": "0c52d8a741f740a6b83be51ae7082b62",
                        "internalURL": "http://controller:8774/v2/de8f43bfe4244a1aa315a70a43248d60",
                        "publicURL": "http://controller:8774/v2/de8f43bfe4244a1aa315a70a43248d60",
                        "region": "RegionOne"
                    }
                ],
                "endpoints_links": [],
                "name": "nova",
                "type": "compute"
            },
            {
                "endpoints": [
                    {
                        "adminURL": "http://controller:9696",
                        "id": "3d70017df8ee40d698988ad52b25cc8e",
                        "internalURL": "http://controller:9696",
                        "publicURL": "http://controller:9696",
                        "region": "RegionOne"
                    }
                ],
                "endpoints_links": [],
                "name": "neutron",
                "type": "network"
            },
            {
                "endpoints": [
                    {
                        "adminURL": "http://controller:35357/v2.0",
                        "id": "23bb295b14554d2b89535d67632e7c60",
                        "internalURL": "http://controller:5000/v2.0",
                        "publicURL": "http://controller:5000/v2.0",
                        "region": "RegionOne"
                    }
                ],
                "endpoints_links": [],
                "name": "keystone",
                "type": "identity"
            }
        ],
        "token": {
            "audit_ids": [
                "XNBLV1ohSXensbuHqwTo3Q"
            ],
            "expires": "2015-11-06T11:29:22Z",
            "id": "b1470e1f13284a8b8f979eb652e29db5",
            "issued_at": "2015-11-06T10:29:22.423828",
            "tenant": {
                "description": "Admin Project",
                "enabled": true,
                "id": "de8f43bfe4244a1aa315a70a43248d60",
                "name": "admin"
            }
        },
        "user": {
            "id": "9c20d9fe21a14741ac1486b2db058bd5",
            "name": "admin",
            "roles": [
                {
                    "name": "admin"
                }
            ],
            "roles_links": [],
            "username": "admin"
        }
    }
}

這裏面有不少關於這個tenant的信息，其中最重要的是token的id，爲b1470e1f13284a8b8f979eb652e29db5，這是咱們後面調取api須要的，還有注意de8f43bfe4244a1aa315a70a43248d60是tenant_id。

接下來咱們開始看看這個項目裏面的虛擬機

curl -v -H "X-Auth-Token:b1470e1f13284a8b8f979eb652e29db5" http://controller_ip:8774/v2/tenant_id/servers

把獲得的令牌寫好，執行後獲得以下信息：

{
    "servers": [
        {
            "id": "098982e0-251d-4306-9171-f4d52674fde3",
            "links": [
                {
                    "href": "http://9.111.222.23:8774/v2/de8f43bfe4244a1aa315a70a43248d60/servers/098982e0-251d-4306-9171-f4d52674fde3",
                    "rel": "self"
                },
                {
                    "href": "http://9.111.222.23:8774/de8f43bfe4244a1aa315a70a43248d60/servers/098982e0-251d-4306-9171-f4d52674fde3",
                    "rel": "bookmark"
                }
            ],
            "name": "vm2"
        },
        {
            "id": "86baaddc-3c3e-4687-87bc-2e22f53eb7ba",
            "links": [
                {
                    "href": "http://9.111.222.23:8774/v2/de8f43bfe4244a1aa315a70a43248d60/servers/86baaddc-3c3e-4687-87bc-2e22f53eb7ba",
                    "rel": "self"
                },
                {
                    "href": "http://9.111.222.23:8774/de8f43bfe4244a1aa315a70a43248d60/servers/86baaddc-3c3e-4687-87bc-2e22f53eb7ba",
                    "rel": "bookmark"
                }
            ],
            "name": "vm1"
        }
    ]
}

這裏能夠明顯看到有兩個虛擬機，分別爲vm1和vm2，這都是我以前建立的。

 

再看看個人image有哪些

curl -v -H "X-Auth-Token:b1470e1f13284a8b8f979eb652e29db5" http://controller_ip:8774/v2/de8f43bfe4244a1aa315a70a43248d60/images | python -mjson.tool

執行後獲得如下信息

{
    "images": [
        {
            "id": "cfa488bb-f5aa-4f67-830c-6d84a1b0f062",
            "links": [
                {
                    "href": "http://9.111.222.23:8774/v2/de8f43bfe4244a1aa315a70a43248d60/images/cfa488bb-f5aa-4f67-830c-6d84a1b0f062",
                    "rel": "self"
                },
                {
                    "href": "http://9.111.222.23:8774/de8f43bfe4244a1aa315a70a43248d60/images/cfa488bb-f5aa-4f67-830c-6d84a1b0f062",
                    "rel": "bookmark"
                },
                {
                    "href": "http://controller:9292/images/cfa488bb-f5aa-4f67-830c-6d84a1b0f062",
                    "rel": "alternate",
                    "type": "application/vnd.openstack.image"
                }
            ],
            "name": "windows7-x86_64-bpm20150724"
        },
        {
            "id": "5c997a18-3f93-41bb-8ce2-724b10d0d418",
            "links": [
                {
                    "href": "http://9.111.222.23:8774/v2/de8f43bfe4244a1aa315a70a43248d60/images/5c997a18-3f93-41bb-8ce2-724b10d0d418",
                    "rel": "self"
                },
                {
                    "href": "http://9.111.222.23:8774/de8f43bfe4244a1aa315a70a43248d60/images/5c997a18-3f93-41bb-8ce2-724b10d0d418",
                    "rel": "bookmark"
                },
                {
                    "href": "http://controller:9292/images/5c997a18-3f93-41bb-8ce2-724b10d0d418",
                    "rel": "alternate",
                    "type": "application/vnd.openstack.image"
                }
            ],
            "name": "rhel7.1"
        },
        {
            "id": "e1c3cc65-54ae-4a76-9646-2d4dc3b7473b",
            "links": [
                {
                    "href": "http://9.111.222.23:8774/v2/de8f43bfe4244a1aa315a70a43248d60/images/e1c3cc65-54ae-4a76-9646-2d4dc3b7473b",
                    "rel": "self"
                },
                {
                    "href": "http://9.111.222.23:8774/de8f43bfe4244a1aa315a70a43248d60/images/e1c3cc65-54ae-4a76-9646-2d4dc3b7473b",
                    "rel": "bookmark"
                },
                {
                    "href": "http://controller:9292/images/e1c3cc65-54ae-4a76-9646-2d4dc3b7473b",
                    "rel": "alternate",
                    "type": "application/vnd.openstack.image"
                }
            ],
            "name": "cirros-0.3.4-x86_64"
        }
    ]
}

能夠看到我一共有3個鏡像

 

至此，其餘api查看文檔進行查看便可，都是類似的方法，這裏僅做一個簡單介紹。

 

 

2、使用火狐firefox 的 restclient 工具來 使用 openstack的api

下面我還嘗試了一些Firefox的restclient，來調取api

固然須要打開火狐瀏覽器安裝restclient的插件https://addons.mozilla.org/en-US/firefox/addon/restclient/，固然使用java的客戶端也能夠http://code.google.com/p/rest-client/

 

這裏演示兩個rest的方法來使用，get和post

 

先看看post：

咱們來取一個ADMIN用戶的admin的tenant的令牌。

對比下curl的命令

curl -k -X 'POST' -v http://controller_ip:5000/v2.0/tokens -d '{"auth":{"passwordCredentials":{"username": "ADMIN", "password":"MY_PASSWORD"},"tenantId":"de8f43bfe4244a1aa315a70a43248d60"}}' -H 'Content-type: application/json' | python -mjson.tool

先設置http的header ，name爲 Content-Type ，value爲 application/json

 

設置好後輸入網址http://controller_ip:5000/v2.0/tokens，而且把要post的json的數據寫入到body裏面，最後點擊按鈕SEND便可，能夠獲得和curl同樣的json數據

 

接下來試試使用get的方法

咱們獲得了tenant的token，就可使用get方法獲取其虛擬機的信息

注意要先設置token在header中，name爲X-Auth-Token，value爲token,而後輸入網址，選擇爲get方法，點擊SEND便可獲得：

 

其餘的api幾乎都是get和post的方法，這裏簡單演示了firefox的restclient的用法，但願你們多多指教
