How can I convert a json array to an array of structs? Example:

  {"name": "Rob"},
  {"name": "John"}

I'm retrieving the json from a request:

body, err := ioutil.ReadAll(r.Body)

How would I unmarshal this into an array?

如何将json数组转换为结构数组? 示例:

 {“ name”:“ Rob”},
 {“ name”:“ John”} 
  <  / pre> 


  body,err:= ioutil.ReadAll(r.Body)

    you simply use json.Unmarshal for this. Example:

    import "encoding/json"
    // This is the type we define for deserialization.
    // You can use map[string]string as well
    type User struct {
        // The `json` struct tag maps between the json name
        // and actual name of the field
        Name string `json:"name"`
    // This functions accepts a byte array containing a JSON
    func parseUsers(jsonBuffer []byte) ([]User, error) {
        // We create an empty array
        users := []User{}
        // Unmarshal the json into it. this will use the struct tag
        err := json.Unmarshal(jsonBuffer, &users)
        if err != nil {
            return nil, err
        // the array is now filled with users
        return users, nil
