Overview

You can access the objects under a bucket using your own endpoint (the custom endpoint, for example, test.cos.com). Detailed directions are as follows:

• Supporting HTTPS for a custom endpoint with CDN acceleration enabled
• Supporting HTTPS for a custom endpoint with CDN acceleration disabled

Enabling CDN Acceleration

Directions

1. Bind a custom endpoint

Bind the bucket to your own endpoint and enable CDN acceleration. For detailed directions, please see Enabling Custom Accelerated Domain Name.

2. Configure HTTPS access

You can configure HTTPS access in the CDN console. For detailed directions, please see HTTPS Configuration Guide.

Disabling CDN Acceleration

This section uses an example to describe how to support HTTPS access in COS by configuring custom endpoints through a reverse proxy (with CDN acceleration disabled). In this example, we use the custom endpoint https://test.cos.com to directly access the testhttps-1250000000 bucket in the Guangzhou region with CDN acceleration disabled. The specific steps are as follows:

Directions

1. Bind a custom endpoint

Bind the testhttps bucket to the https://test.cos.com endpoint and disable CDN acceleration. For detailed directions, please see Enabling Custom Accelerated Domain Name.

2. Configure a reverse proxy for the endpoint

Configure a reverse proxy for the https://test.cos.com endpoint on the server, as shown below (the Nginx configuration is for reference only):

shell
server {
   listen        443;
   server_name  test.cos.com ;
    ssl on;
   ssl_certificate /usr/local/nginx/conf/server.crt;
   ssl_certificate_key /usr/local/nginx/conf/server.key;
    error_log logs/test.cos.com.error_log;
   access_log logs/test.cos.com.access_log;
   location / {
       root /data/www/;
       proxy_pass  http://testhttps-1250000000.cos.ap-guangzhou.myqcloud.com; // Configure the default download domain for the bucket. 
   }
}

Server.crt; and server.key are HTTPS certificates for your own (custom) endpoint. If no HTTPS certificate is in place for your endpoint, you can apply for one at Tencent Cloud SSL Certificate Service.
If no certificate is available, the following configuration information can be deleted, but an alarm will occur during access. Click Continue to access the bucket:

shell
ssl on;
ssl_certificate /usr/local/nginx/conf/server.crt;
ssl_certificate_key /usr/local/nginx/conf/server.key;

3. Resolve the endpoint to the server

Resolve your endpoint at your DNS hosting provider. If you are using Tencent Cloud’s DNS service, please go to the DNSPod console to map test.cos.com to the server’s IP in Step 2. For more information, please see Adding a DNS Record.

4. Advanced settings

• Opening the web page in a browser directly

After configuring the custom endpoint to support HTTPS, you can download objects in the bucket using your endpoint. If your business requires directly accessing web pages and images in a browser, you can use the static website feature. For detailed directions, please see Setting up a Static Website.
After the configuration is completed, add the following code to the Nginx configuration file, restart Nginx, and refresh the browser cache.

bash
proxy_set_header Host $http_host;

• Configuring referer hotlink protection

Public buckets might be hotlinked. You can use the hotlink protection feature to set a referer allowlist to prevent malicious hotlinking as follows:

1. Log in to the COS console, enable the hotlink protection feature, and configure an allowlist. For detailed directions, please see Setting Hotlink Protection.
2. Add the following code to the Nginx configuration file, restart Nginx, and refresh the browser cache.

   bash
   proxy_set_header   Referer www.test.com;
   

3. After the configuration, if you open the file directly, the error errorcode: -46616 (error message: not hit white refer) will be reported. In this case, you can access the custom endpoint with a proxy to open the page.

   json
   {
   errorcode: -46616,
   errormsg: "not hit white refer, retcode:-46616"
   }
