How to Initialize Embedded Structs in Go: A Focus on http.Request?

Initializing Embedded Structs in Go

When embedding a struct within another struct, it's often necessary to initialize the embedded struct as well. This question focuses on initializing the inner http.Request embedded within the outer MyRequest struct.

To initialize the embedded struct, modify the code in the New function as follows:

req := new(MyRequest)
req.PathParams = pathParams
req.Request = origRequest

Alternatively, you can also use the following syntax:

req := &MyRequest{
  PathParams: pathParams,
  Request: origRequest,
}

Both approaches accomplish the same result. The first method invokes new to create a pointer to a new MyRequest struct, while the second method directly assigns values to a struct literal.

Initializing the embedded struct is crucial for properly using the MyRequest struct. The embedded Request field provides access to the original HTTP request, while the PathParams field contains a map of path parameters. By properly initializing these fields, you can take advantage of the embeded struct's functionality.
