      Overview

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

      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

      cos_pool_t *p = NULL;
      cos_request_options_t *options = NULL;
      cos_pool_create(&p, NULL);
      options = cos_request_options_create(p);
      options->config = cos_config_create(options->pool);
      // The request domain format is <bucketname-appid>.file.myqcloud.com.
      cos_str_set(&options->config->endpoint, "<bucketname-appid>.file.myqcloud.com");

      Parameter description

      Parameter
      Description
      Type
      endpoint
      Set the domain suffix to use the CDN acceleration domain name
      String

      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

      cos_pool_t *p = NULL;
      cos_request_options_t *options = NULL;
      cos_pool_create(&p, NULL);
      options = cos_request_options_create(p);
      options->config = cos_config_create(options->pool);
      // Set the requested endpoint to `your.domain.com`
      cos_str_set(&options->config->endpoint, "your.domain.com"); // Custom CDN domain
      // Set `is_cname` to `1`
      options->config->is_cname = 1;

      Parameter description

      Parameter
      Description
      Type
      endpoint
      Set the domain suffix to use a custom CDN endpoint
      String
      is_cname
      Set this parameter to 1 to use the custom CDN endpoint mode
      Int

      Custom origin server domain name

      Description

      After setting a custom origin server domain for a bucket through the COS console, you can set the domain in the SDK code to access COS resources. For more information, please see Enabling Custom Endpoints.

      Sample code

      cos_pool_t *p = NULL;
      cos_request_options_t *options = NULL;
      cos_pool_create(&p, NULL);
      options = cos_request_options_create(p);
      options->config = cos_config_create(options->pool);
      // Set the requested endpoint to `your.domain.com`
      cos_str_set(&options->config->endpoint, "your.domain.com"); // Custom endpoint
      // Set `is_cname` to `1`
      options->config->is_cname = 1;

      Parameter description

      Parameter
      Description
      Type
      endpoint
      Set the domain suffix to use a custom origin server endpoint
      String
      is_cname
      Set this parameter to 1 to use the custom origin server endpoint mode
      Int

      Global acceleration endpoint

      Description

      After enabling a global acceleration endpoint for a bucket through the COS console, you can set the domain name in the SDK code for global acceleration. For more information, please see Global Acceleration Overview.

      Sample code

      cos_pool_t *p = NULL;
      cos_request_options_t *options = NULL;
      cos_pool_create(&p, NULL);
      options = cos_request_options_create(p);
      options->config = cos_config_create(options->pool);
      // Set the requested endpoint to `cos.accelerate.myqcloud.com`
      cos_str_set(&options->config->endpoint, "cos.accelerate.myqcloud.com");

      Parameter description

      Parameter
      Description
      Type
      endpoint
      Set the domain suffix to use a global acceleration endpoint
