[Chrome extension] Connect http/https website via proxy have username and password or proxy anonymous

I wrote a chrome extension to help my chrome browser use a proxy to connect http / https sites. I use 2 types of proxies, that is, anonymous proxies and proxies with accounts and passwords. I only use https proxies, do not use sock5 or any other type. This Chrome extension has the following tasks: Step 1: When I access any path, but in the path with the character "command = set_proxy", it will immediately execute the set proxy command for the entire browser, meaning that all websites have access to it. via that proxy. I used the [login to view URL] event (callback, filter, opt_extraInfoSpec); To catch the url, discover that the words "command = set_proxy" will immediately set the proxy, without waiting for the browser to process the site then set the proxy, it will set immediately, without waiting. Example of a link: [login to view URL] If the proxy is anonymous, the path will look like this: [login to view URL] Redirect after setting the proxy [login to view URL]://[login to view URL] However, I have a big problem with the type of proxy identifier that requires a username and password. I can't send "Proxy-Authorization" parameters in "request Header" every time I change another proxy (probably because of cache, or anything, I don't know) I already have the source code available, fix it for me, or you can write in your own way.
