Obtaining the Static Website Hosting Configuration of a Bucket (SDK for Go)

Function

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

Redirecting all requests to another website
Redirecting specific requests

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

Restrictions

To obtain the static website hosting configuration 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

func (obsClient ObsClient) GetBucketWebsiteConfiguration(bucketName string) (output *GetBucketWebsiteConfigurationOutput, err error)

Request Parameters

**Table 1** List of request parameters
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 a period (.) and a hyphen (-) 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 2** List of returned results
Parameter	Type	Description
output	*GetBucketWebsiteConfigurationOutput	Explanation: Returned results. For details, see Table 3.
err	error	Explanation: Error messages returned by the API

**Table 3** GetBucketWebsiteConfigurationOutput
Parameter	Type	Description
StatusCode	int	Explanation: HTTP status code Value range: A status code is a group of digits that can be 2xx (indicating successes) or 4xx or 5xx (indicating errors). It indicates the status of a response. For more information, see Status Code. Default value: None
RequestId	string	Explanation: Request ID returned by the OBS server Default value: None
ResponseHeaders	map[string][]string	Explanation: HTTP response headers Default value: None
RedirectAllRequestsTo	RedirectAllRequestTo	Explanation: Redirection rule of all requests For details, see Table 4.
IndexDocument	IndexDocument	Explanation: Default page configuration. For details, see Table 5.
ErrorDocument	ErrorDocument	Explanation: Error page configuration. For details, see Table 6.
RoutingRules	[]RoutingRule	Explanation: Redirection rule list For details, see Table 7.

**Table 4** RedirectAllRequestsTo
Parameter	Type	Description
HostName	string	Explanation: Host name used for redirection, for example, www.example.com Restrictions: The host name must be in the standard host name format. Default value: None
Protocol	ProtocolType	Explanation: Protocol used for redirection Value range: See Table 10. Default value: None

**Table 5** IndexDocument
Parameter	Type	Mandatory (Yes/No)	Description
Suffix	string	Yes if IndexDocument is specified	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

**Table 6** ErrorDocument
Parameter	Type	Mandatory (Yes/No)	Description
Key	string	No if ErrorDocument is specified	Explanation: Object name to use when a 4XX error occurs. This parameter specifies the webpage to display when an error occurs. Value range: The value must contain 1 to 1,024 characters. Default value: None

**Table 7** RoutingRule
Parameter	Type	Description
Condition	Condition	Explanation: Conditions that must be met for the specified redirect to apply Value range: See Table 8. Default value: None
Redirect	Redirect	Explanation: Details about the redirect request. For details, see Table 9.

**Table 8** Condition
Parameter	Type	Mandatory (Yes/No)	Description
KeyPrefixEquals	string	No	Explanation: Object name prefix when the redirection is applied. When a request is sent for accessing an object, the redirection rule takes effect if the object name prefix matches the value specified for this parameter. For example, to redirect the request for object ExamplePage.html, set the 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 codes when the redirection takes effect. The specified redirection is applied only when the error code returned equals the value specified for this parameter. For example, if you want to redirect requests to NotFound.html when HTTP error code 404 is returned, set HttpErrorCodeReturnedEquals to 404 in Condition, 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 9** Redirect
Parameter	Type	Description
Protocol	ProtocolType	Explanation: Protocol used for redirection Value range: See Table 10. Default value: None
HostName	string	Explanation: Host name used for redirection Default value: None
ReplaceKeyPrefixWith	string	Explanation: Object name prefix used for redirection Value range: The value must contain 1 to 1,024 characters. Default value: None
ReplaceKeyWith	string	Explanation: Object name used for redirection 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	Explanation: HTTP status code in the response to the redirect request. For details, see Status Code. Default value: None

**Table 10** ProtocolType
Constant	Default Value	Description
ProtocolHttp	http	HTTP protocol used for redirection
ProtocolHttps	https	HTTPS protocol used for the redirection request
