Overview

This document describes how to request the COS service using a non-default endpoint.

Default CDN acceleration domain name

Feature 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.

Method prototype

void com.qcloud.cos.ClientConfig.setEndPointSuffix(String endPointSuffix)

Sample request

// 1. Use a CDN acceleration domain. COS verification information does not need to be sent.
COSCredentials cred = new AnonymousCOSCredentials();
// 2. Set the region abbreviation for the bucket. For abbreviations of COS regions, please see https://intl.cloud.tencent.com/document/product/436/6224?from_cn_redirect=1
ClientConfig clientConfig = new ClientConfig(new Region("ap-beijing"));
// HTTPS is recommended.
clientConfig.setHttpProtocol(HttpProtocol.https);
// 3. Set the suffix for the default CDN acceleration domain.
String cdnSuffix = "file.myqcloud.com";
clientConfig.setEndPointSuffix(cdnSuffix);
// 4. Generate a COS client
COSClient cosclient = new COSClient(cred, clientConfig);

Parameter description

Custom CDN acceleration domain name

Feature 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.

Method prototype

void com.qcloud.cos.ClientConfig.setEndpointBuilder(EndpointBuilder endpointBuilder)

Sample request

// 1. Use a CDN acceleration domain. COS verification information does not need to be sent.
COSCredentials cred = new AnonymousCOSCredentials();
// 2. Set the region abbreviation for the bucket. For abbreviations of COS regions, please see https://intl.cloud.tencent.com/document/product/436/6224?from_cn_redirect=1
ClientConfig clientConfig = new ClientConfig(new Region("ap-beijing"));
// HTTPS is recommended, which requires the custom domain to have the relevant SSL certificate.
clientConfig.setHttpProtocol(HttpProtocol.https);
// 3. Set the custom CDN domain name.
// The get service request will use this domain, which is fixed.
String serviceApiEndpoint = "service.cos.myqcloud.com";
String cdnEndpoint = "xxx.xxx.com";
UserSpecifiedEndpointBuilder endPointBuilder = new UserSpecifiedEndpointBuilder(cdnEndpoint, serviceApiEndpoint);
clientConfig.setEndpointBuilder(endPointBuilder);
// 4. Generate a COS client
COSClient cosclient = new COSClient(cred, clientConfig);

Parameter description

UserSpecifiedEndpointBuilder description:

Custom origin server domain name

Feature 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.

Method prototype

void com.qcloud.cos.ClientConfig.setEndpointBuilder(EndpointBuilder endpointBuilder)

Sample request

// 1. Initialize user authentication information (secretId, secretKey).
COSCredentials cred = new BasicCOSCredentials("AKIDXXXXXXXX", "1A2Z3YYYYYYYYYY");
// 2. Set the region abbreviation for the bucket. For abbreviations of COS regions, please see https://intl.cloud.tencent.com/document/product/436/6224?from_cn_redirect=1
ClientConfig clientConfig = new ClientConfig(new Region("ap-beijing"));
// HTTPS is recommended.
clientConfig.setHttpProtocol(HttpProtocol.https);
// 3. Set the custom domain name.
// The get service request will use this domain, which is fixed.
String serviceApiEndpoint = "service.cos.myqcloud.com";
String userEndpoint = "xxx.xxx.com";
UserSpecifiedEndpointBuilder endPointBuilder = new UserSpecifiedEndpointBuilder(userEndpoint, serviceApiEndpoint);
clientConfig.setEndpointBuilder(endPointBuilder);
// 4. Generate a COS client
COSClient cosclient = new COSClient(cred, clientConfig);

Parameter description

UserSpecifiedEndpointBuilder description:

Global acceleration endpoint

Feature 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.

Method prototype

void com.qcloud.cos.ClientConfig.setEndPointSuffix(String endPointSuffix)

Sample request

// 1. Initialize user authentication information (secretId, secretKey).
COSCredentials cred = new BasicCOSCredentials("AKIDXXXXXXXX", "1A2Z3YYYYYYYYYY");
// 2. Set the region abbreviation for the bucket. For abbreviations of COS regions, please see https://intl.cloud.tencent.com/document/product/436/6224?from_cn_redirect=1
ClientConfig clientConfig = new ClientConfig(new Region("ap-beijing"));
// HTTPS is recommended.
clientConfig.setHttpProtocol(HttpProtocol.https);
// 3. Set the suffix for the global acceleration endpoint.
String cosSuffix = "cos.accelerate.myqcloud.com";
clientConfig.setEndPointSuffix(cosSuffix);
// 4. Generate a COS client
COSClient cosclient = new COSClient(cred, clientConfig);
