QingCloud Service Usage Guide

Import and initialize QingCloud service with a config, and you are ready to use the initialized service.

Each API function take a Input struct and return an Output struct. The Input struct consists of request params, request headers and request elements, and the Output holds the HTTP status code, response headers, response elements and error (if error occurred).

import (
	qc "github.com/yunify/qingcloud-sdk-go/service"
)

Code Snippet

Initialize the QingCloud service with a configuration

qcService, _ := qc.Init(configuration)

Initialize the instance service in a zone

pek3aInstance, _ := qcService.Instance("pek3a")

DescribeInstances

iOutput, _ := pek3aInstance.DescribeInstances(
	&qc.DescribeInstancesInput{
		Instances: qc.StringSlice([]string{"i-xxxxxxxx"}),
	},
)

// Print the return code.
fmt.Println(qc.IntValue(iOutput.RetCode))

// Print the first instance ID.
fmt.Println(qc.StringValue(iOutput.InstanceSet[0].InstanceID))

RunInstances

iOutput, _ := pek3aInstance.RunInstances(
	&qc.RunInstancesInput{
		ImageID:      qc.String("centos7x64d"),
		CPU:          qc.Int(1),
		Memory:       qc.Int(1024),
		LoginMode:    qc.String("keypair"),
		LoginKeyPair: qc.String("kp-xxxxxxxx"),
	},
)

// Print the return code.
fmt.Println(qc.IntValue(iOutput.RetCode))

// Print the job ID.
fmt.Println(qc.StringValue(iOutput.JobID))

Initialize the volume service in a zone

pek3aVolume, _ := qcService.Volume("pek3a")

DescribeVolumes

volOutput, _ := pek3aVolume.DescribeVolumes(&qc.DescribeVolumesInput{
	Volumes: qc.StringValue([]string{"vol-xxxxxxxx"}),
})

// Print the return code.
fmt.Println(qc.IntValue(volOutput.RetCode))

// Print the first volume name.
fmt.Println(qc.StringValue(volOutput.VolumeSet[0].VolumeName))

CreateVolumes

volOutput, _ := pek3aVolume.CreateVolumes(
	&qc.CreateVolumesInput{
		Size:  qc.Int(10),
		Count: qc.Int(2),
	},
)

// Print the return code.
fmt.Println(qc.IntValue(volOutput.RetCode))

// Print the job ID.
fmt.Println(qc.StringValue(volOutput.JobID))
