设置跨域规则
您可以通过setBucketCORS设置桶的跨域规则,如果原规则存在则覆盖原规则。以下代码展示了如何设置跨域规则:
static OBSClient *client; NSString *endPoint = @"your-endpoint"; // 认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险,建议在配置文件或者环境变量中密文存放,使用时解密,确保安全;本示例以ak和sk保存在环境变量中为例,运行本示例前请先在本地环境中设置环境变量AccessKeyID和SecretAccessKey。 // 您可以登录访问管理控制台获取访问密钥AK/SK,获取方式请参见https://support.huaweicloud.com/intl/zh-cn/usermanual-ca/ca_01_0003.html char* ak_env = getenv("AccessKeyID"); char* sk_env = getenv("SecretAccessKey"); NSString *AK = [NSString stringWithUTF8String:ak_env]; NSString *SK = [NSString stringWithUTF8String:sk_env]; // 初始化身份验证 OBSStaticCredentialProvider *credentialProvider = [[OBSStaticCredentialProvider alloc] initWithAccessKey:AK secretKey:SK]; //初始化服务配置 OBSServiceConfiguration *conf = [[OBSServiceConfiguration alloc] initWithURLString:endPoint credentialProvider:credentialProvider]; // 初始化client client = [[OBSClient alloc] initWithConfiguration:conf]; // 设置桶的跨域资源共享 OBSSetBucketCORSRequest *request = [[OBSSetBucketCORSRequest alloc] initWithBucketName:@"bucketname"]; OBSCORSRule* rule = [OBSCORSRule new]; // 指定允许的跨域请求方法(GET/PUT/DELETE/POST/HEAD) rule.allowedMethodList = @[OBSCORSHTTPGET,OBSCORSHTTPPUT,OBSCORSHTTPPOST,OBSCORSHTTPHEAD]; // 指定允许跨域请求的来源 rule.allowedOriginList = @[@"www.example1.com",@"www.example2.com"]; // 允许的header rule.allowedHeaderList = @[@"allowedheader1",@"allowedheader2"]; // 指定允许用户从应用程序中访问的header rule.exposeHeaderList = @[@"exposeheader_1",@"exposeheader_2"]; // 指定浏览器对特定资源的预取(OPTIONS)请求返回结果的缓存时间,单位为秒 rule.maxAgeSeconds = [NSNumber numberWithInt:100]; [request.bucketCORSRuleList addObject:rule]; [client setBucketCORS:request completionHandler:^(OBSSetBucketCORSResponse *response, NSError *error) { NSLog(@"%@",response); }];
