Configuring Static Website Hosting for a Bucket (SDK for Go)

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 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 configures static website hosting for a bucket.

Restrictions

Periods (.) should be avoided in the target bucket name, or there may be certificate verification failures on the client when you use HTTPS for access.
The request body of the website configuration cannot exceed 10 KB.
To configure static website hosting for a bucket, you must be the bucket owner or have the required permission (obs:bucket:PutBucketWebsite in IAM or PutBucketWebsite in a bucket policy). For details, see Introduction to OBS Access Control, IAM Custom Policies, and Creating a Custom Bucket Policy.

Method

func (obsClient ObsClient) SetBucketWebsiteConfiguration(input *SetBucketWebsiteConfigurationInput) (output *BaseModel, err error)

Request Parameters

**Table 1** List of request parameters
Parameter	Type	Mandatory (Yes/No)	Description
input	*SetBucketWebsiteConfigurationInput	Yes	Explanation: Input parameters for configuring static website hosting. For details, see Table 2.

**Table 2** SetBucketWebsiteConfigurationInput
Parameter	Type	Mandatory (Yes/No)	Description
Bucket	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. Value range: The value must contain 3 to 63 characters.
RedirectAllRequestsTo	RedirectAllRequestTo	No	Explanation: Redirection rules for all requests. For details, see Table 3.
IndexDocument	IndexDocument	No	Explanation: Default page configuration. For details, see Table 4.
ErrorDocument	ErrorDocument	No	Explanation: Error page configuration. For details, see Table 5.
RoutingRules	[]RoutingRule	No	Explanation: List of routing rules. For details, see Table 6.

ErrorDocument, IndexDocument, and RoutingRules must be used together and they cannot be used with RedirectAllRequestsTo.
When ErrorDocument, IndexDocument, and RoutingRules are used together, RoutingRules can be left blank.
You must specify either the three parameters (ErrorDocument, IndexDocument, and RoutingRules), or RedirectAllRequestsTo.

**Table 3** RedirectAllRequestsTo
Parameter	Type	Mandatory (Yes/No)	Description
HostName	string	Yes if RedirectAllRequestsTo is specified	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	ProtocolType	No	Explanation: Protocol used for redirection Value range: See Table 9. Default value: None

**Table 4** 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 5** 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 6** RoutingRule
Parameter	Type	Mandatory (Yes/No)	Description
Condition	Condition	No	Explanation: Conditions that must be met for the specified redirect to apply Value range: See Table 7. Default value: None
Redirect	Redirect	Yes if RoutingRule is specified	Explanation: Details about the redirection. For details, see Table 8.

**Table 7** 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 8** Redirect
Parameter	Type	Mandatory (Yes/No)	Description
Protocol	ProtocolType	No if used as a request parameter	Explanation: Protocol used for redirection Value range: See Table 9. Default value: None
HostName	string	No if used as a request parameter	Explanation: Host name used for redirection Default value: None
ReplaceKeyPrefixWith	string	No if used as a request parameter	Explanation: Object name prefix used for redirection Value range: The value must contain 1 to 1,024 characters. Default value: None
ReplaceKeyWith	string	No if used as a request parameter	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	No if used as a request parameter	Explanation: HTTP status code in the response to the redirect request. For details, see Status Code. Default value: None

**Table 9** ProtocolType
Constant	Default Value	Description
ProtocolHttp	http	HTTP protocol used for redirection
ProtocolHttps	https	HTTPS protocol used for the redirection request

Responses

**Table 10** List of returned results
Parameter	Type	Description
output	*BaseModel	Explanation: Returned results. For details, see Table 11.
err	error	Explanation: Error messages returned by the API

**Table 11** BaseModel
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
