This change allows middleware to replace the logger on the echo.Context
with a customized per-request logger with additional fields. The logger
is reset to default on every Reset() call.
Otherwise, the `http.ResponseWriter` passed to `next()` within the
middleware is unused. This precludes middlewares from wrapping the
http.ResponseWriter to do things like record the status code.
* Added feature to map url params to a struct with the default binder
* Added test for mix of POST data and bound params
* Renamed variables
* Added error check
* Removed unneded fix
* feat: Add a new ErrorHandlerWithContext
This commit adds a new error handler, which is passed the
current context, so that you can add custom redirects or even
other kinds of responses. For example:
```go
e.Use(middleware.JWTWithConfig(middleware.JWTConfig{
SigningKey: []byte("secret"),
TokenLookup: "query:token",
ErrorHandlerWithContext: func(err error, c echo.Context) error {
// do stuff with context and err
switch err.(type) {
case jwt.ValidationError:
return c.Redirect(http.StatusSeeOther, "/login")
}
return err
},
}))
```
* chore: address golint issues
* echo.context.cjson should encode the JSON before writing the status code #1334 :
`response.Write` automatically sets status to `200` if a response code wasn't committed yet. This is convenient, but it ignores the fact that `response.Status` is a public field that may be set separately/before `response.Write` has been called
A `response.Status` is by default `0`, or `200` if the response was reset, so `response.Write` should fallback to `200` only if a code wasn't set yet.
* echo.context.cjson should encode the JSON before writing the status code #1334 :
Writing the response code before encoding the payload is prone to error.
If JSON encoding fails, the response code is already committed, the server is able to only modify the response body to reflect the error and the user receives an awkward response where the status is successful but the body reports an error.
Instead - set the desired code on `c.response.Status`. If writing eventually takes place, the desired code is committed. If an error occurs, the server can still change the response.
