Customize Marshal and Unmarshal

Default behaviour #

Req uses the go standard library’s marshal and unmarshal function by default:

• Use json.Marshal or xml.Marshal to marshal request body if you pass struct or map into Request.SetBody, Request.SetBodyJsonMarshal or Request.SetBodyXmlMarshal.
• Use json.Unmarshal or xml.Unmarshal to unmarshal response body if you pass struct or map into Request.SetResult, Request.SetError or Response.Unmarshal.

Customization #

You can customize the marshal function with Client.SetJsonMarshal or Client.SetXmlMarshal if you need more advanced customization:

// Example of registering json-iterator
import jsoniter "github.com/json-iterator/go"

json := jsoniter.ConfigCompatibleWithStandardLibrary

client := req.C().
	SetJsonMarshal(json.Marshal).
	SetJsonUnmarshal(json.Unmarshal)

// Similarly, XML functions can also be customized
client.SetXmlMarshal(xmlMarshalFunc).SetXmlUnmarshal(xmlUnmarshalFunc)
