API | Operation | Description |
Configuring a preflight request for cross-origin access | Sends a preflight request to check whether a real cross-origin access request can be sent |
OPTIONS Object) is used to send a preflight request to check the CORS configuration of an object. Before making an actual CORS request, you can send an OPTIONS request that includes the source origin, HTTP method, and headers to COS to determine whether an actual CORS request can be sent. If there is no CORS configuration, "403 Forbidden" will be returned. You can enable CORS for a bucket using the PUT Bucket cors API.cos.optionsObject({Bucket: 'examplebucket-1250000000', /* Your bucket name. Required. */Region: 'COS_REGION', /* Bucket region, such as `ap-beijing`. Required. */Key: '1.jpg', /* Object key stored in the bucket (such as `1.jpg` and `a/b/test.txt`). Required. */Origin: 'https://www.qq.com', /*Required*/AccessControlRequestMethod: 'PUT', /*Required*/AccessControlRequestHeaders: 'origin,accept,content-type' /*Optional*/}, function(err, data) {console.log(err || data);});
