Setting Website Hosting

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

You can call set_bucket_website_configuration to set website hosting on a bucket.

Configuring the Default Homepage, Error Pages and Redirection Rules

The following code shows how to configure the default home page, error pages, and redirection rules. The following table describes the parameters.

Field	Type	Mandatory or Optional	Description
option	The context of the bucket. For details, see Configuring option.	Mandatory	Bucket parameter
set_bucket_redirect_all	obs_set_bucket_redirect_all_conf *	Mandatory	Indicates the redirection configuration.
set_bucket_redirect_all->host_name	const char *	Mandatory	Indicates the name of the host where requests will be redirected.
set_bucket_redirect_all->protocol	const char *	Optional	The HTTP or HTTPS protocol used in redirecting requests. The default protocol is HTTP.
set_bucket_website_conf	obs_set_bucket_website_conf *	Mandatory	Describes the configuration of the website element in the redirection rules.
set_bucket_website_conf->suffix	const char *	Mandatory	Suffix that is appended to a request initiated for a directory on the website endpoint. For example, if the suffix is index.html and you request for samplebucket/images/, the data that is returned will be the object with the key name images/index.html in the samplebucket bucket. Suffix cannot be empty or contain slashes (/).
set_bucket_website_conf->key	const char *	Optional	Indicates the object name that is used when a 4XX error occurs. This element identifies the page that is returned when a 4XX error occurs.
set_bucket_website_conf->routingrule_info	bucket_website_routingrule *	Optional	For details about redirection rules, see the following table.
set_bucket_website_conf->routingrule_count	int	Optional	Total size of set_bucket_website_conf.routingrule_info
handler	obs_response_handler*	Mandatory	Callback function
callback_data	void *	Optional	Callback data

The following table describes the redirection rule structure bucket_website_routingrule.

Field	Type	Mandatory or Optional	Description
key_prefix_equals	const char *	Optional	Indicates the object name prefix when the redirection is applied.
http_errorcode_returned_equals	const char *	Optional	Indicates HTTP error codes when the redirection takes effect. The specified redirection is applied only when the error code returned equals this value.
protocol	const char *	Optional	Indicates protocol used in the redirection request.
host_name	const char *	Optional	Indicates the host name used in the redirection request.
replace_key_prefix_with	const char *	Optional	Indicates the object name prefix used in the redirection request.
replace_key_with	const char *	Optional	Indicates the object name used in the redirection request.
http_redirect_code	const char *	Optional	Indicates the HTTP status code returned after the redirection request.

Configuring Redirection for All Requests

Sample code:

{
    obs_status ret_status = OBS_STATUS_BUTT;
    // Create and initialize option.
    obs_options option;
    init_obs_options(&option);

    option.bucket_options.bucket_name = "<Your bucketname>";

    option.bucket_options.secret_access_key = getenv("SECRET_ACCESS_KEY");
    // Set response callback function.
    obs_response_handler response_handler =

    // Configure redirection for all requests.

    set_bucket_website_configuration(&option, &set_bucket_redirect_all, NULL,
