在Go Lang POST请求中创建JSON负载？

request, err := http.NewRequest("POST", url,bytes.NewBuffer(**myJsonPayload**))

I am new in Go and trying to make post request with dynamic 'myJsonPayload', which will be changing for different request.

Use Marshal in the encoding/json package of Go's standard library to encode your data as JSON.

Signature:

func Marshal(v interface{}) ([]byte, error)

Example from package docs, where input data happens to be a struct type with int, string, and string slice field types:

type ColorGroup struct {
    ID     int
    Name   string
    Colors []string
}
group := ColorGroup{
    ID:     1,
    Name:   "Reds",
    Colors: []string{"Crimson", "Red", "Ruby", "Maroon"},
}
b, err := json.Marshal(group)

You can also use map for dynamically changing json payload. Below is the example code to do this.

payload := map[string]interface{}{"id":1, "name":"zahid"}
byts, _ := json.Marshal(payload)
fmt.Println(string(byts)) // {"id":1,"name":"zahid"}
