To send a Virtual Private Cloud (VPC) API request, you must send an HTTP GET request to the VPC endpoint. You must add the request parameters that correspond to the API operation being called. After you call the API, the system returns a response. The request and response are encoded in UTF-8.
Request example
VPC API operations use the RPC protocol. You can call VPC API operations by sending HTTP GET requests.
This topic uses the CreateVpc operation as an example to describe an unencoded URL request:
https://vpc.aliyuncs.com/?Action=CreateVpc
&RegionId=cn-hangzhou
&<Common Request Parameters>
https
specifies the protocol for transmitting the request.VPC API operations support communication over the HTTP or HTTPS protocol. For security purposes, we recommend that you send requests over HTTPS.
vpc.aliyuncs.com
specifies the endpoint of VPC.To minimize network latency, we recommend that you specify the endpoint based on the region where you call API operations. The following table lists the endpoints of the VPC API.Note For regions that are not listed in the following table, usevpc.aliyuncs.com
.Region Endpoint Default vpc.aliyuncs.com China (Zhangjiakou-Beijing Winter Olympic) vpc.cn-zhangjiakou.aliyuncs.com China (Hohhot) vpc.cn-huhehaote.aliyuncs.com China (Ulanqab) vpc.cn-wulanchabu.aliyuncs.com China (Chengdu) vpc.cn-chengdu.aliyuncs.com China (Heyuan) vpc.cn-heyuan.aliyuncs.com China (Guangzhou) vpc.cn-guangzhou.aliyuncs.com Japan (Tokyo) vpc.ap-northeast-1.aliyuncs.com Germany (Frankfurt) vpc.eu-central-1.aliyuncs.com UAE (Dubai) vpc.me-east-1.aliyuncs.com Australia (Sydney) vpc.ap-southeast-2.aliyuncs.com Malaysia (Kuala Lumpur) vpc.ap-southeast-3.aliyuncs.com India (Mumbai) vpc.ap-south-1.aliyuncs.com Indonesia (Jakarta) vpc.ap-southeast-5.aliyuncs.com UK (London) vpc.eu-west-1.aliyuncs.com Note VPC endpoints use public service addresses. If the Elastic Compute Service (ECS) instance in your VPC cannot access the Internet, you cannot call API operations by using Alibaba Cloud CLI or SDKs. To call API operations over VPCs, see Call API operations over a VPC.Action=CreateVpc
specifies the operation that is being called.RegionId=cn-hangzhou
is a required parameter of the CreateVpc operation.<Common request parameters>
are common parameters defined in the system.For more information, see Common parameters.
