Write in front
There are not a few articles about qiniu cloud uploading pictures, but they just use the test domain name given by qiniu cloud. As a webmaster, after upgrading his domain name to https, the obsessive-compulsive patients are not allowed to have the three words of insecurity in the browser. Of course, there will be some holes when using qiniu cloud to bind his domain name. In order to better maintain their own website, not necessarily perfect for all, but try to do the best!
preparation
- Because my personal server belongs to alicloud, I applied for a secondary domain name on my alicloud (how to apply for alicloud secondary domain name: Click here)
- After the second level domain name application is completed, you need to purchase an ssl certificate. Alicloud has a free certificate to apply for another one!
- And download the ssl certificate! (no configuration such as Nginx is required.)
Seven cattle cloud configuration
New storage
The space name can be customized, and access control selection is public.
At this point, you are finished with the new one.
Configure domain name
Upload https certificate, first level domain name certificate and second level domain name certificate to qiniu cloud first.
In space management, click domain name to configure domain name. First bind primary domain name, then bind secondary domain name. The binding is completed as follows.
Of course, there are pits here. If cname is not used, the following problems will occur.
If you directly create A new cname in the primary domain name, that is, in Alibaba cloud, the record value and - A will always conflict. If you modify - A directly, the following problems will occur.
So we need a secondary domain name!
