Overview

COS 对象的跨域访问配置预请求的方法.

功能说明

跨域访问配置的预请求是指在发送跨域请求之前会发送一个 OPTIONS 请求并带上特定的来源域，HTTP 方法 和 header 信息等给 COS，以决定是否可以发送真正的跨域请求.

关于COS 对象的跨域访问配置预请求接口的具体描述，请查看https://cloud.tencent.com/document/product/436/8288.

示例

@code

QCloudOptionsObjectRequest* request = [[QCloudOptionsObjectRequest alloc] init];

request.bucket =@"存储桶名";

request.origin = @"*";

request.accessControlRequestMethod = @"get";

request.accessControlRequestHeaders = @"host";

request.object = @"对象名";

[request setFinishBlock:^(id outputObject, NSError* error) {

}];
[[QCloudCOSXMLService defaultCOSXML] OptionsObject:request];
