Is it possible to bind query/form multi name(alias)?

[yinheli]

I knew the bind does not support this feature.

e.g.

type Node struct {
  Name string `json:"name" query:"name,n,code"`
}

where Name field's query to support ?name=xxx or ?n=xxx or ?code=xxx

Bind itself does not have that feature, but you could add additional code to do the same

type Node struct {
    Name string `json:"name" query:"name"`
}
n := Node{}
if err := c.Bind(&n); err != nil {
    return err
}
err := echo.QueryParamsBinder(c).
    // String("name", &n.Name).  // <-- not needed as Bind knows that from struct tag
    String("n", &n.Name).
    String("code", &n.Name).
    BindError()
if err != nil {
    return err
}

Or if I do something like rewrite request query?

// original query
query := c.Request().URL.Query()

// handle alias
if query.Has("n") {
  query.Set("name", query.Get("n"))
}

// ...

c.Request().URL.RawQuery = query.Encode()

// then do bind logic 
err := c.Bind(&data)
// ...

yes, you could do that. It is a little bit more code but result is same.
