将值追加到c.Json响应

package main

import (
    "encoding/json"
    "net/http"
)

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

func handler(w http.ResponseWriter, r *http.Request) {
    c := struct {
        Data string `json:"data"`
    }{
        Data: "original data",
    }

    newData := struct {
        NewData string `json:"new_data"`
    }{
        NewData: "new data",
    }

    // 将新的键值对合并到原有的JSON数据中
    mergedData := map[string]interface{}{
        "data":      c.Data,
        "new_data":  newData.NewData,
    }

    // 转换为JSON格式
    response, err := json.Marshal(mergedData)
    if err != nil {
        http.Error(w, err.Error(), http.StatusInternalServerError)
        return
    }

    w.Header().Set("Content-Type", "application/json")
    w.Write(response)
}
