gin+gorm开发一个简单的用户管理系统实战核心代码

新增用户

接口代码：

package router

import (
	"github.com/zhangdapeng520/zdpgo_gin"
	"gorm_api_user/g"
	"gorm_api_user/model"
)

func userAdd(c *zdpgo_gin.Context) {
	var user model.User
	c.ShouldBindJSON(&user)

	// 创建数据
	g.GDB.Create(&user)

	// 返回
	c.JSON(200, user)
}

测试代码：

package router

import (
	"github.com/zhangdapeng520/zdpgo_httprouter"
	"io"
	"os"
	"testing"
)

func TestUserAdd(t *testing.T) {
	targetUrl := "http://127.0.0.1:8888/user"
	data := map[string]interface{}{
		"name": "张三",
		"age":  30,
	}
	resp, err := zdpgo_httprouter.SendJson("POST", targetUrl, data)
	if err != nil {
		t.Error(err)
	}
	io.Copy(os.Stdout, resp.Body)
}

删除用户

接口代码：

package router

import (
	"github.com/zhangdapeng520/zdpgo_gin"
	"gorm_api_user/g"
	"gorm_api_user/model"
	"strconv"
)

func userDelete(c *zdpgo_gin.Context) {
	idStr := c.Param("id")
	id, _ := strconv.Atoi(idStr)

	g.GDB.Delete(&model.User{Id: id})

	c.JSON(200, nil)
}

测试代码：

package router

import (
	"github.com/zhangdapeng520/zdpgo_httprouter"
	"io"
	"os"
	"testing"
)

func TestUserDelete(t *testing.T) {
	targetUrl := "http://127.0.0.1:8888/user/3"
	data := map[string]interface{}{}
	resp, err := zdpgo_httprouter.SendJson("DELETE", targetUrl, data)
	if err != nil {
		t.Error(err)
	}
	io.Copy(os.Stdout, resp.Body)
}

修改用户

接口代码：

package router

import (
	"github.com/zhangdapeng520/zdpgo_gin"
	"gorm_api_user/g"
	"gorm_api_user/model"
	"strconv"
)

func userUpdate(c *zdpgo_gin.Context) {
	var user model.User
	c.ShouldBindJSON(&user)

	idStr := c.Param("id")
	id, _ := strconv.Atoi(idStr)
	user.Id = id
	g.GDB.Model(model.User{Id: id}).Update("name", user.Name, "age", user.Age)

	c.JSON(200, nil)
}

测试代码：

package router

import (
	"github.com/zhangdapeng520/zdpgo_httprouter"
	"io"
	"os"
	"testing"
)

func TestUserUpdate(t *testing.T) {
	targetUrl := "http://127.0.0.1:8888/user/7"
	data := map[string]interface{}{
		"name": "李四",
		"age":  30,
	}
	resp, err := zdpgo_httprouter.SendJson("PUT", targetUrl, data)
	if err != nil {
		t.Error(err)
	}
	io.Copy(os.Stdout, resp.Body)
}

查询用户

接口代码：

package router

import (
	"github.com/zhangdapeng520/zdpgo_gin"
	"gorm_api_user/g"
	"gorm_api_user/model"
	"strconv"
)

func userGetAll(c *zdpgo_gin.Context) {
	var users []model.User
	g.GDB.Find(&users)

	c.JSON(200, users)
}

func userGet(c *zdpgo_gin.Context) {
	idStr := c.Param("id")
	id, _ := strconv.Atoi(idStr)

	var user model.User
	g.GDB.Find(&user, "id=?", id)

	c.JSON(200, user)
}

测试代码：

package router

import (
	"io"
	"net/http"
	"os"
	"testing"
)

func TestUserGetAll(t *testing.T) {
	targetUrl := "http://127.0.0.1:8888/user"
	resp, err := http.Get(targetUrl)
	if err != nil {
		t.Error(err)
	}
	io.Copy(os.Stdout, resp.Body)
}

func TestUserGet(t *testing.T) {
	targetUrl := "http://127.0.0.1:8888/user/7"
	resp, err := http.Get(targetUrl)
	if err != nil {
		t.Error(err)
	}
	io.Copy(os.Stdout, resp.Body)
