Access Log Format Logger

Access log mode is used to view the full body detail of all request and response in the endpoints.

Usage

Importing

import "github.com/AccelByte/go-restful-plugins/v4/pkg/logger/log"

Log all endpoints

ws := new(restful.WebService)
ws.Filter(log.AccessLog)

Log specific endpoint

ws := new(restful.WebService)
ws.Route(ws.GET("/user/{id}").
    Filter(log.AccessLog).
    To(func(request *restful.Request, response *restful.Response) {
}))

Environment variables

Filter sensitive field(s) in request body or response body

Some endpoint might have sensitive field value in its query params, request body or response body. For security reason, those sensitive field value should be masked before it printed as a log.

The log.Attribute filter can be used to define the field(s) that need to be masked.

ws := new(restful.WebService)
ws.Route(ws.GET("/user/{id}").
    Filter(log.AccessLog).
    Filter(log.Attribute(log.Option{
        MaskedQueryParams: "param1,param2",
        MaskedRequestFields: "field1,field2",
        MaskedResponseFields: "field3,field4",
    })).
    To(func(request *restful.Request, response *restful.Response) {
}))

Manually specify log's field value

We could manually set specific field value via request attribute. Please refer to the table below for attribute name of each field.

Example:

// ... your service logic
request.SetAttribute(log.NamespaceAttribute, "myNamespace")
request.SetAttribute(log.UserIDAttribute, "myUserId")
request.SetAttribute(log.ClientIDAttribute, "myClientId")
// ... your service logic
