Configuring a Preflight Request for Cross-origin Access

Description

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

Sample code

// Bucket name in the format of BucketName-APPID (APPID is required), which can be viewed in the COS console at https://console.intl.cloud.tencent.com/cos5/bucket
String bucket = "examplebucket-1250000000";
String cosPath = "exampleobject"; // The 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;
   }
    // If you use the Kotlin language to call this, please note that the exception in the callback method is nullable; otherwise, the onFail method will not be called back, that is:
   // clientException is of type CosXmlClientException? and serviceException is of type CosXmlServiceException?
   @Override
   public void onFail(CosXmlRequest cosXmlRequest,
                      @Nullable CosXmlClientException clientException,
                      @Nullable CosXmlServiceException serviceException) {
       if (clientException != null) {
           clientException.printStackTrace();
       } else {
           serviceException.printStackTrace();
       }
   }
});
