For convenience in certain scenarios, it may be necessary to convert a struct to a map in Golang. This can be achieved through the reflect and json packages.
One approach involves utilizing the reflect package to inspect the structure of the struct and build a map dynamically. This can be done using the provided ConvertToMap function:
<br>func ConvertToMap(model interface{}) bson.M {</p>
<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">ret := bson.M{}
modelReflect := reflect.ValueOf(model)
... // Implementation
return ret}
Alternatively, the structs package offers a convenient and comprehensive solution. It supports various operations involving structs, including converting them to maps. For instance, the following code snippet utilizes the Map function:
<br>type Server struct {</p>
<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">Name string
ID int32
Enabled bool}
s := &Server{
Name: "gopher", ID: 123456, Enabled: true,
}
m := structs.Map(s) // => {"Name":"gopher", "ID":123456, "Enabled":true}
The structs package handles scenarios such as anonymous (embedded) fields and nested structs. Additionally, it provides options for filtering fields through the use of field tags.
