JSON without escaping

[qulxizer]

I need to serve JSON responses that include full URLs containing query parameters. However, I'm encountering an issue where the URLs are being escaped—for example, characters like & and = in query parameters are converted to \u0026 and \u003d.

In the Go standard library, json.Encoder.SetEscapeHTML(false) allows disabling this behavior. Is there a similar way to achieve this in Echo when using c.JSON(...), or do I need to manually handle the response to prevent escaping?

It's possible to specify your own JSONSerializer instead of the default one and set enc.SetEscapeHTML(false) during serialization:

e := echo.New() e.JSONSerializer = &MyJSONSerializer{} ...

// DefaultJSONSerializer implements JSON encoding using encoding/json. type MyJSONSerializer echo.DefaultJSONSerializer // Serialize converts an interface into a json and writes it to the response. // You can optionally use the indent parameter to produce pretty JSONs. func (d MyJSONSerializer) Serialize(c echo.Context, i interface{}, indent string) error { enc := json.NewEncoder(c.Response()) enc.SetEscapeHTML(false) if indent != "" { enc.SetIndent("", indent)	} return enc.Encode(i) } // Deserialize reads a JSON from a request body and converts it into an interface. func (d MyJSONSerializer) Deserialize(c echo.Context, i interface{}) error { return echo.DefaultJSONSerializer(d).Deserialize(c, i) }

See how it''s implemented in Echo:
