javascript - Upload failed token not specified

The same code
Uploading normally under www.a.com
Under www.b.com, the same code, getting the token through www.a.com and uploading error: "token not specified"

Uptoken under uptoken_func returns a null value before being assigned a value by the data called back by ajax, so the token is empty when uploading

It seems that the poster’s code is uploading files to Qiniu CDN
Regarding the token problem, the poster can check whether it is a JS cross-domain issue. You can also look at Qiniu’s development documents or contact Qiniu’s technical staff. Adjust it

After the ajax under uptoken_func cross-domain, its running order has changed. All programs have been executed before the uptoken under success is assigned a value, so the uploaded uptoken is empty
