File Storage

uploadFile

1. Interface Description

Interface Function: Upload files to the File Management Service

Interface declaration: uploadFile(object: Object): Promise<Object>

Note

After version 1.0.1, to improve file upload performance, the file upload method has been modified to direct upload to object storage. To prevent CORS errors during usage, you need to log in to the CloudBase Console and add domains in the Security Domains section on the Security Sources page. If existing domains encounter CORS errors, please delete them from the security domains and add them again.

onUploadProgress	function	No	Upload progress callback

Note

cloudPathis the absolute path of the file, including the file name, e.g., foo/bar.jpg, foo/bar/baz.jpg, etc. Must not contain characters other than [0-9, a-z, A-Z], /, !, -, \_, ., ,, \*, and Chinese.
