#### 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"},

#### 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")
|
||||
}
|
||||
