luceos
in my situation.
upload.xxx.cn is my CDN domain, and xxx.com is my local domain,
i mean:
files like pdf i would like it be uploaded and visit by original links, it saves in my server computer.
images be uploaded to CDN to make it fast to visit.
but now, if I set CDN(OSS Link) and image upload to QINIU, Images will be upload to QINIU, pdf will be uploaded to my server, but all them return the CDN links, pdf wont be uploaded to CDN(QINIU), so we can't use this link to open it, only original links can visit.
i dont know if i explain it well. sorry to take your time, thank you luceos anyway!
