使用AK调用API

创建AccessKey后，第三方平台可以使用AccessKey调用ZStack Cloud私有云API，方法如下：

SDK方式：

以创建云主机（CreateVmInstance）为例，使用AccessKey调用ZStack Cloud 私有云API时，需输入accessKeyId和accessKeySecret，示例如下：

Java SDK

CreateVmInstanceAction action = new CreateVmInstanceAction(); action.name = "vm1"; action.instanceOfferingUuid = "ae97ced44efc3314b8f7798972b4ba1a"; action.imageUuid = "da119f7906513eccabf271991c35a65e"; action.l3NetworkUuids = asList("cc0e4c5e77df3af68e59668e7f9e06c5"); action.dataDiskOfferingUuids = asList("19d22d051b063d379a2816daaf431838","905d94a6abb5398fa1995f6398e3f6fc"); action.clusterUuid = "a0468dc645223f67bd0f2ab95276bbae"; action.description = "this is a vm"; action.strategy = "InstantStart"; action.accessKeyId = "Fnxc7KIQAdGTvXfx8OjC"; action.accessKeySecret = "Do0AJUGVPrT9iJZlc1QOtk7kzEusYidyqJxSmKOb"; CreateVmInstanceAction.Result res = action.call();

Python SDK

CreateVmInstanceAction action = CreateVmInstanceAction() action.name = "vm1" action.instanceOfferingUuid = "ae97ced44efc3314b8f7798972b4ba1a" action.imageUuid = "da119f7906513eccabf271991c35a65e" action.l3NetworkUuids = [cc0e4c5e77df3af68e59668e7f9e06c5] action.dataDiskOfferingUuids = [19d22d051b063d379a2816daaf431838, 905d94a6abb5398fa1995f6398e3f6fc] action.clusterUuid = "a0468dc645223f67bd0f2ab95276bbae" action.description = "this is a vm" action.strategy = "InstantStart" action.accessKeyId = "Fnxc7KIQAdGTvXfx8OjC" action.accessKeySecret = "Do0AJUGVPrT9iJZlc1QOtk7kzEusYidyqJxSmKOb" CreateVmInstanceAction.Result res = action.call()

直接调用ZStack Cloud 私有云RESTful API方式：

创建AccessKey：

CreateAccessKey accountUuid=dff4fb9bbff14e97a67ab894c7b8c528 userUuid=dff4fb9bbff14e97a67ab894c7b8c528 {     "inventory": {         "AccessKeyID": "N3Tf05yXZUmSjCf6mYIB",         "AccessKeySecret": "XAlrsYvswmnEV3X1KWNs1WfZHD6aBIIphmI0rX9S",         "accountUuid": "dff4fb9bbff14e97a67ab894c7b8c528",         "createDate": "Sep 6, 2018 1:50:06 PM",         "lastOpDate": "Sep 6, 2018 1:50:06 PM",         "userUuid": "dff4fb9bbff14e97a67ab894c7b8c528",         "uuid": "ae353717ca7b4182bb87fb5d010235e8"     },     "success": true }

生成date：

python get_time.py Thu, 06 Sep 2018 13:54:10 PRC

import datetime import time   date = time.time() #EEE, dd MMM yyyy HH:mm:ss z str = datetime.datetime.fromtimestamp(date).strftime('%a, %d %b %Y %H:%M:%S PRC') print str

说明: 时间格式必须为EEE, dd MMM yyyy HH:mm:ss zzz。

生成digest：

python get_accesskey.py "vvSZpmj4cnB53qUDmm6E" "8heumeFTvIeZxkTGfEYvVi9qVVPd9ffQNDALSPPb" \ "GET" "Fri, 06 Aug 2021 17:58:34 PRC" "/v1/vm-instances" # 以下为返回结果 args: Namespace(acesskey_id='vvSZpmj4cnB53qUDmm6E', acesskey_secret='8heumeFTvIeZxkTGfEYvVi9qVVPd9ffQNDALSPPb', \ date='Fri, 06 Aug 2021 17:58:34 PRC', method='GET', uri='/v1/vm-instances') Signature: hPToRHeHdV49D4u20G8OlE0yJho= Authoration ZStack vvSZpmj4cnB53qUDmm6E:hPToRHeHdV49D4u20G8OlE0yJho=

#/usr/bin/python import base64 import hmac import sha import argparse from hashlib import sha1   parser = argparse.ArgumentParser(description='calculate zstack access key digit.') parser.add_argument('acesskey_id') parser.add_argument('acesskey_secret') parser.add_argument('method') parser.add_argument('date') parser.add_argument('uri')   args = parser.parse_args()   print "args: %s" % args h = hmac.new(args.acesskey_secret, args.method + "\n"                                     + args.date + "\n"                                     + args.uri, sha1) Signature = base64.b64encode(h.digest()) print "Signature: %s" % Signature print "Authoration %s" % ("ZStack " + args.acesskey_id + ":" + Signature)

发送请求
```
curl -H "Authorization:ZStack vvSZpmj4cnB53qUDmm6E:hPToRHeHdV49D4u20G8OlE0yJho=" \ -H "Content-Type:application/x-www-form-urlencoded" \ -H "Date:Fri, 06 Aug 2021 17:58:34 PRC" \ -X GET http://172.20.11.134:8080/zstack/v1/vm-instances
```
说明: API请求header字段说明：
- Authorization字段值应与第三步生成的digest中Authorization字段值保持一致，格式为："ZStack " + args.acesskey_id + ":" + Signature
- Date字段值应与生成digest时的时间戳保持一致
