Overview

This document describes how to use a non-default domain to request COS.

Setting the default COS domain

Sample request

// Replace examplebucket-1250000000 and COS_REGION with the actual information.
u, _ := url.Parse("https://examplebucket-1250000000.cos.COS_REGION.myqcloud.com")
// The following calls the `Get Service` API. By default, all regions (service.cos.myqcloud.com) will be queried.
su, _ := url.Parse("https://cos.COS_REGION.myqcloud.com")
b := &cos.BaseURL{BucketURL: u, ServiceURL: su}
// 1. Permanent key
client := cos.NewClient(b, &http.Client{
  Transport: &cos.AuthorizationTransport{
      SecretID:  "SECRETID",
      SecretKey: "SECRETKEY",
  },
})

Default CDN acceleration domain name

Description

After enabling a default CDN acceleration domain name for a bucket through the COS console, you can set the domain name in the SDK code for acceleration.
For more information, please see Enabling Default CDN Acceleration Domain Names.

Sample request

// Replace examplebucket-1250000000 with the actual information.
u, _ := url.Parse("https://examplebucket-1250000000.file.myqcloud.com")
b := &cos.BaseURL{BucketURL: u}
// Use a CDN acceleration domain. COS verification information does not need to be sent.
client := cos.NewClient(b, &http.Client{})

Custom CDN acceleration domain name

Description

After setting a custom CDN acceleration domain name for a bucket through the COS console, you can set the domain name in the SDK code to implement acceleration for the custom domain. For more information, please see Enabling Custom Accelerated Domain Name.

Sample request

// Set the custom CDN acceleration domain.
u, _ := url.Parse("https://xxx.xxx.com")
b := &cos.BaseURL{BucketURL: u}
// Use a CDN acceleration domain. COS verification information does not need to be sent.
client := cos.NewClient(b, &http.Client{})

Custom origin server domain name

Sample request

// Custom origin server domain
u, _ := url.Parse("https://xxx.xxx.com")
b := &cos.BaseURL{BucketURL: u}
client := cos.NewClient(b, &http.Client{
 Transport: &cos.AuthorizationTransport{
     SecretID:  "SECRETID",
     SecretKey: "SECRETKEY",
 },
})

Global acceleration endpoint

Sample request

// Global acceleration domain
// Replace examplebucket-1250000000 with the actual information.
u, _ := url.Parse("https://examplebucket-1250000000.cos.accelerate.myqcloud.com")
b := &cos.BaseURL{BucketURL: u}
client := cos.NewClient(b, &http.Client{
 Transport: &cos.AuthorizationTransport{
     SecretID:  "SECRETID",
     SecretKey: "SECRETKEY",
 },
})
