Obtaining Static Website Hosting Configurations (SDK for Java)

Function

You can host static website resources such as HTML web pages, flash files, or audio and video files in an OBS bucket, so that you can provide these hosted resources using the bucket's website endpoint to end users. Typical use cases include:

Redirecting all requests to another website
Redirecting specific requests to another website

This API returns the static website hosting configurations of the bucket.

If you have any questions during development, post them on the Issues page of GitHub.

Restrictions

To obtain the static website hosting configurations of a bucket, you must be the bucket owner or have the required permission (obs:bucket:GetBucketWebsite in IAM or GetBucketWebsite in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.
The mapping between OBS regions and endpoints must comply with what is listed in Regions and Endpoints.

Method

obsClient.getBucketWebsite(final BaseBucketRequest request)

Request Parameters

**Table 1** List of request parameters
Parameter	Type	Mandatory (Yes/No)	Description
request	BaseBucketRequest	Yes	Explanation: Request parameters related to basic bucket information. For details, see Table 2.

**Table 2** BaseBucketRequest
Parameter	Type	Mandatory (Yes/No)	Description
bucketName	String	Yes	Explanation: Bucket name. Restrictions: A bucket name must be unique across all accounts and regions. A bucket name: Must be 3 to 63 characters long and start with a digit or letter. Lowercase letters, digits, hyphens (-), and periods (.) are allowed. Cannot be formatted as an IP address. Cannot start or end with a hyphen (-) or period (.). Cannot contain two consecutive periods (..), for example, my..bucket. Cannot contain periods (.) and hyphens (-) adjacent to each other, for example, my-.bucket or my.-bucket. If you repeatedly create buckets of the same name in the same region, no error will be reported and the bucket attributes comply with those set in the first creation request. Default value: None

Responses

**Table 3** WebsiteConfiguration
Parameter	Type	Mandatory (Yes/No)	Description
suffix	String	No	Explanation: Suffix that is appended to the request for a directory. For example, if the suffix is index.html and you request samplebucket/images/, the returned data will be for the object named images/index.html in the bucket samplebucket. Value range: This parameter can neither be left blank nor contain slashes (/). Default value: None
key	String	No	Explanation: Object name to use when a 4XX error occurs. This parameter specifies the web page to display when an error occurs. Value range: The value must contain 1 to 1,024 characters. Default value: None
redirectAllRequestsTo	RedirectAllRequest	No	Explanation: Redirection rules for all requests. For details, see Table 4.
routeRules	List<RouteRule>	No	Explanation: List of routing rules. For details, see Table 6.

**Table 4** RedirectAllRequest
Parameter	Type	Mandatory (Yes/No)	Description
hostName	String	Yes	Explanation: Host name used for redirection, for example, www.example.com. Restrictions: The host name must comply with the host name rules. Default value: None
protocol	ProtocolEnum	No	Explanation: Protocol used for redirection. Value range: See Table 5. Default value: None

**Table 5** ProtocolEnum
Constant	Default Value	Description
HTTP	http	HTTP protocol used for redirection.
HTTPS	https	HTTPS protocol used for redirection.

**Table 6** RouteRule
Parameter	Type	Mandatory (Yes/No)	Description
condition	RouteRuleCondition	No	Explanation: Conditions of a redirection rule. For details, see Table 7.
redirect	Redirect	Yes	Explanation: Details about the redirection. For details, see Table 8.

**Table 7** RouteRuleCondition
Parameter	Type	Mandatory (Yes/No)	Description
keyPrefixEquals	String	No	Explanation: Object name prefix for the redirection to take effect. If the name prefix of the requested object is the same as the value specified for this parameter, the redirection rule takes effect. For example, to redirect the requests for the object ExamplePage.html, set keyPrefixEquals to ExamplePage.html. Restrictions: This parameter cannot be used together with httpErrorCodeReturnedEquals. Value range: The value must contain 1 to 1,024 characters. Default value: None
httpErrorCodeReturnedEquals	String	No	Explanation: HTTP error code for the redirection to take effect. If there is an error, and the error code returned is the same as the value specified for this parameter, the redirection rule takes effect. For example, if you want to redirect requests to NotFound.html when HTTP error code 404 is returned, set httpErrorCodeReturnedEquals to 404 in RouteRuleCondition, and set replaceKeyWith to NotFound.html in Redirect. Restrictions: This parameter cannot be used together with keyPrefixEquals. Value range: See Error Codes. Default value: None

**Table 8** Redirect
Parameter	Type	Mandatory (Yes/No)	Description
Protocol	ProtocolEnum	No	Explanation: Protocol used for redirection. Value range: See Table 5. Default value: None
hostName	String	No	Explanation: Host name used for redirection. Default value: None

replaceKeyWith	String	No	Explanation: Object name used in the redirection request. Restrictions: This parameter cannot be used together with replaceKeyPrefixWith. Value range: The value must contain 1 to 1,024 characters. Default value: None
httpRedirectCode	String	No	Explanation: HTTP status code in the response to the redirect request. For details, see Status Code. Default value: None

Code Examples

This example returns the website configuration of bucket examplebucket using obsClient.getBucketWebsite.

    
     
       
       
         import com.obs.services.ObsClient;

        // Obtain an AK/SK pair on the management console.
        String ak = System.getenv("ACCESS_KEY_ID");
        String sk = System.getenv("SECRET_ACCESS_KEY_ID");
        // (Optional) If you are using a temporary AK/SK pair and a security token to access OBS, you are advised not to use hard coding, which may result in information leakage.
        // Obtain an AK/SK pair and a security token using environment variables or import them in other ways.
        // String securityToken = System.getenv("SECURITY_TOKEN");
        // Enter the endpoint corresponding to the bucket. CN-Hong Kong is used here as an example. Replace it with the one in your actual situation.
        String endPoint = "https://obs.ap-southeast-1.myhuaweicloud.com";
        // Obtain an endpoint using environment variables or import it in other ways.
        //String endPoint = System.getenv("ENDPOINT");

            // Request failed. Print the HTTP status code.
            System.out.println("HTTP Code:" + e.getResponseCode());
            // Request failed. Print the server-side error code.
            System.out.println("Error Code:" + e.getErrorCode());
            // Request failed. Print the error details.
            System.out.println("Error Message:" + e.getErrorMessage());
            // Request failed. Print the request ID.
            System.out.println("Request ID:" + e.getErrorRequestId());
            System.out.println("Host ID:" + e.getErrorHostId());
            e.printStackTrace();
        } catch (Exception e) {
