#### Using BasicAuth() middleware
```go
func main() {
r := gin.Default()
// note than: type gin.H map[string]interface{}
secrets := gin.H{
"foo": gin.H{"email": "foo@bar.com", "phone": "123433"},

"user": user,
"secret": secret
}

}
}
}
// hit "localhost:8080/admin/secrets
// Listen and server on 0.0.0.0:8080
r.Run(":8080")
}
```
#### Goroutines inside a middleware
When starting inside a middleware or handler, you **SHOULD NOT** use the original context inside it, you have to use a read-only copy.
```go
func main() {
r := gin.Default()
r.GET("/long_async", func(c *gin.Context) {
// create copy to be used inside the goroutine
c_cp := c.Copy()
go func() {
// simulate a long task with time.Sleep(). 5 seconds
time.Sleep(5 * time.Second)
// note than you are using the copied context "c_cp", IMPORTANT
log.Println("Done! in path " + c_cp.Req.URL.Path)
}()
})
r.GET("/long_sync", func(c *gin.Context) {
// simulate a long task with time.Sleep(). 5 seconds
time.Sleep(5 * time.Second)
// since we are NOT using a goroutine, we do not have to copy the context
log.Println("Done! in path " + c.Req.URL.Path)
})
// Listen and server on 0.0.0.0:8080
r.Run(":8080")
}
```
