Middleware

Method Override

Override POST methods from headers or custom getters.

HTML forms can only send GET and POST. MethodOverride lets a POST request say which method it really means, so forms can reach PUT, PATCH, and DELETE routes. It runs before routing.

app.Use(middleware.MethodOverride())

The default source is:

X-HTTP-Method-Override

The original method is preserved in:

X-Original-Method

Use query-based or custom lookup when needed.

app.Use(middleware.MethodOverrideWithConfig(middleware.MethodOverrideConfig{
  Getter: middleware.MethodOverrideFromFirst(
    middleware.MethodOverrideFromHeader("X-HTTP-Method-Override"),
    middleware.MethodOverrideFromQuery("_method"),
  ),
}))
