Configuring a Preflight Request for Cross-origin Access

Feature description

This API is used to get the cross-origin access configuration for a preflight request.

Sample code

String bucket = "examplebucket-1250000000"; // Bucket name in the format: `BucketName-APPID`
String cosPath = "exampleobject"; // Location identifier of the object in the bucket, i.e., the object key
String origin = "https://cloud.tencent.com";
String accessMethod = "PUT";
OptionObjectRequest optionObjectRequest = new OptionObjectRequest(bucket,
        cosPath, origin,
        accessMethod);
cosXmlService.optionObjectAsync(optionObjectRequest,
        new CosXmlResultListener() {
    @Override
    public void onSuccess(CosXmlRequest cosXmlRequest, CosXmlResult result) {
        OptionObjectResult optionObjectResult = (OptionObjectResult) result;
    }

    @Override
    public void onFail(CosXmlRequest cosXmlRequest,
                       CosXmlClientException clientException,
                       CosXmlServiceException serviceException) {
        if (clientException != null) {
            clientException.printStackTrace();
        } else {
            serviceException.printStackTrace();
        }
    }
});
