How to support HTTPS in Beego

I want my beego website to support https.

There are another post Beego and Https. I try that method enable chrome setting chrome://flags/#allow-insecure-localhost or open url with Microsoft Edge. It's still show This site can’t be reached.

Environment

go version go1.10 windows/amd64
Beego : 1.10.1

My step is:

Install googleapis.cer to my windows 10 computer.
Copy googleapis.cer and googleapis.keyfile to D:\Go_workspace\src\myproject

Edit D:\Go_workspace\src\myproject\conf\app.conf

appname = myproject
runmode = prod
[dev]
httpaddr = "127.0.0.1"
HTTPPort = 9100
[prod]
httpaddr = "127.0.0.1"
HTTPSPort = 9099
httpsaddr = "127.0.0.1"
EnableHTTPS = true
EnableHttpTLS = true
HTTPSCertFile = "googleapis.cer"
HTTPSKeyFile = "googleapis.key"  
[test]
HTTPSPort = 9099

Run my project with the bee tool command ....\bin\bee run

I get the following message and show message This site can’t be reached when I go to URL https://127.0.0.1:9099 :

2018/11/09 10:07:56.251 [I] [asm_amd64.s:2361]  http server Running on http://127.0.0.1:8080
2018/11/09 10:07:56.253 [I] [asm_amd64.s:2361]  https server Running on https://127.0.0.1:9099
2018/11/09 10:07:56.293 [C] [asm_amd64.s:2361]  ListenAndServeTLS:  listen tcp 127.0.0.1:9099: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted.

Does anyone know how to solve this problem? Thank you

Solution

There is a a possible race condition in beego that makes it intermittent to run both HTTP and HTTPS together. You can see this in app.go

if BConfig.Listen.EnableHTTPS || BConfig.Listen.EnableMutualHTTPS {
    go func() {
        //...
        app.Server.Addr = // the Addr is set to the value of HTTPS addr
        // ListenAndServeTLS()
    }()
}
if BConfig.Listen.EnableHTTP {
    go func() {
        app.Server.Addr = addr // the Addr is set to the valu of HTTP addr
        // ListenAndServe()
    }()
}

As you can see the Server.Addr is set on different goroutines which is a data race.

So I would suggest that you run your app exclusively on HTTPS unless you want to patch beego itself.

e.g. in your app.conf:

EnableHTTP = false
EnableHTTPS = true
