Referer configuration (C++ SDK V2)

Usage notes

• Before you run the sample code, replace <region> with your region, such as cn-hangzhou.

• The sample code reads access credentials from environment variables. For more information, see Configure access credentials.

• To set the referer configuration, you must have the oss:PutBucketReferer permission. To get the referer configuration, you must have the oss:GetBucketReferer permission.

Sample code

#include <iostream>
#include "alibabacloud/oss2/ClientConfiguration.h"
#include "alibabacloud/oss2/OSSClient.h"
#include "alibabacloud/oss2/credentials/CredentialsProvider.h"

namespace oss = alibabacloud::oss2;

int main() {
    auto conf = oss::ClientConfiguration::loadDefault();
    conf.region = "<region>";
    conf.credentialsProvider = std::make_shared<oss::EnvironmentVariableCredentialsProvider>();

    oss::OSSClient client(conf);

    oss::models::RefererList refererList;
    refererList.referers.push_back("https://www.example.com");
    refererList.referers.push_back("https://*.example.com");

    oss::models::RefererConfiguration refConf;
    refConf.allowEmptyReferer = true;
    refConf.refererList = refererList;

    auto outcome = client.putBucketReferer(
        oss::models::PutBucketRefererRequest()
            .setBucket("examplebucket")
            .setRefererConfiguration(refConf));

    if (!outcome.has_value()) {
        auto& e = outcome.error();
        std::cerr << "Failed to set the referer configuration"
