Middleware |
|
Middleware is a function which is chained in the HTTP request-response cycle. Middleware has access to the request and response objects which it utilizes to perform a specific action, for example, logging every request.
Logger
Logs each HTTP request with method, path, status, response time and bytes served.
Example
e.Use(Logger())
// Output: `2015/06/07 18:16:16 GET / 200 13.238µs 14`
BasicAuth
BasicAuth middleware provides an HTTP basic authentication.
- For valid credentials it calls the next handler in the chain.
- For invalid Authorization header it sends "404 - Bad Request" response.
- For invalid credentials, it sends "401 - Unauthorized" response.
Example
e.Group("/admin")
e.Use(mw.BasicAuth(func(usr, pwd string) bool {
if usr == "joe" && pwd == "secret" {
return true
}
return false
}))
Gzip
Gzip middleware compresses HTTP response using gzip compression scheme.
Example
e.Use(mw.Gzip())
Recover
Recover middleware recovers from panics anywhere in the chain and handles the control to the centralized [HTTPErrorHandler]({{< relref "guide/customization.md#http-error-handler">}}).
Example
e.Use(mw.Recover())
