在Go中将字符串从HTTP请求转换为数据结构

package main

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

type Person struct {
    Name  string `json:"name"`
    Age   int    `json:"age"`
    Email string `json:"email"`
}

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

func handlePerson(w http.ResponseWriter, r *http.Request) {
    // 读取请求体中的数据
    body := make([]byte, r.ContentLength)
    r.Body.Read(body)

    // 解析JSON字符串为Person结构体
    var person Person
    err := json.Unmarshal(body, &person)
    if err != nil {
        http.Error(w, err.Error(), http.StatusBadRequest)
        return
    }

    // 打印解析后的数据
    fmt.Printf("Name: %s, Age: %d, Email: %s\n", person.Name, person.Age, person.Email)

    // 返回成功响应
    w.WriteHeader(http.StatusOK)
}
