### Path parameter
|
|
|
|
Path parameter can be retrieved either by name `Context.Param(name string) string`
|
|
or by index `Context.P(i int) string`. Getting parameter by index gives a slightly
|
|
better performance.
|
|
|
|
*Example*
|
|
|
|
```go
|
|
e.Get("/users/:name", func(c *echo.Context) error {
|
|
// By name
|
|
name := c.Param("name")
|
|
|
|
// By index
|
|
name := c.P(0)
|
|
|
|
return c.String(http.StatusOK, name)
|
|
})
|
|
```
|
|
|
|
```sh
|
|
$ curl http://localhost:1323/users/joe
|
|
```
|
|
|
|
### Query parameter
|
|
|
|
Query parameter can be retrieved by name using `Context.Query(name string)`.
|
|
|
|
*Example*
|
|
|
|
```go
|
|
e.Get("/users", func(c *echo.Context) error {
|
|
name := c.Query("name")
|
|
return c.String(http.StatusOK, name)
|
|
})
|
|
```
|
|
|
|
```sh
|
|
$ curl -G -d "name=joe" http://localhost:1323/users
|
|
```
|
|
|
|
### Form parameter
|
|
|
|
Form parameter can be retrieved by name using `Context.Form(name string)`.
|
|
|
|
*Example*
|
|
|
|
```go
|
|
e.Post("/users", func(c *echo.Context) error {
|
|
name := c.Form("name")
|
|
return c.String(http.StatusOK, name)
|
|
})
|
|
```
|
|
|
|
```sh
|
|
$ curl -d "name=joe" http://localhost:1323/users
|
|
```
