视频演示

在这里插入图片描述

1.前端代码(全部)

<template>
	<view>
		<view>
			<button @click="login()">点我进行授权登陆</button>
		</view>
		<!-- 将我们的通过getUserProfile获取到的用户信息进行一个显示处理 -->
		<view>
			<img :src="userInfo.avatarUrl">
			<text>{{userInfo.nickName}}</text>
			
		</view>
		<view>
			<text>信息是:{{msg}}</text>
		</view>
	</view>

</template>

<script>
	export default {
		data() {
			return {
				title: 'Hello',
				userInfo:{
					avatarUrl:'',
					nickName:'',
					
				},
				msg:'',
			}
		},
		onLoad() {

		},
		methods: {
			login() {
				let _this=this;
				uni.getUserProfile({
						provider: 'weixin',
						lang: 'zh_CN',
						desc: '获取您的昵称,头像地区以及性别',
						success: (res) => {
							console.log(res.userInfo);
							// 调用我们的uni.login()方法这个方法可以获取到我们的临时code这个code是我们的需要的
							uni.login({
								provider: 'weixin',
								success(res2) {
									console.log(res2.code);
									_this.userInfo.avatarUrl = res.userInfo.avatarUrl;
									_this.userInfo.nickName = res.userInfo.nickName;
									const user = {
										nickName: res.userInfo.nickName,
										avatarUrl: res.userInfo.avatarUrl,
										code: res2.code//这个只是我们的临时code
									}
									//这个是我们的向我们的后台发送我们的请求(在后台获取我们的用户的openid)
									uni.request({
										method:'POST',
										url:'http://localhost:9898/user/wxLogin',
										data:user,
										success(res) {
											console.log(res.data.msg);
											_this.msg=res.data.msg
											
										}
									})
								}
							})
							}
						})
				}
			}
		}
</script>

<style>
	
</style>

1.getUserProfile()获取用户信息

1.1代码
	uni.getUserProfile({
					provider:'weixin',
					lang:'zh_CN',
					desc:'获取您的昵称,头像地区以及性别',
					success: (res) => {
						console.log(res.userInfo);
					}
				})

打印的结果

2.获取临时code(调用uni.login())

login() {
				let _this=this;
				uni.getUserProfile({
						provider: 'weixin',
						lang: 'zh_CN',
						desc: '获取您的昵称,头像地区以及性别',
						success: (res) => {
							console.log(res.userInfo);
							// 调用我们的uni.login()方法这个方法可以获取到我们的临时code这个code是我们的需要的
							uni.login({
								provider: 'weixin',
								success(res2) {
									console.log(res2.code);
                  //将我们的用户的信息渲染到到我们的页面上边去
									_this.userInfo.avatarUrl = res.userInfo.avatarUrl;
									_this.userInfo.nickName = res.userInfo.nickName;
                  //封装user对象 传递给我们的后台进行数据的存储
									const user = {
										nickName: res.userInfo.nickName,
										avatarUrl: res.userInfo.avatarUrl,
										code: res2.code//这个只是我们的临时code
									}
									//这个是我们的向我们的后台发送我们的请求(在后台获取我们的用户的openid)
									uni.request({
                    //书写你们自己的真实的地址
										url:'',
										data:user,
									})
								}
							})
							}
						})
				}

这个是我们的打印出来的临时code

3.开启一个后端项目(springboot)

3.1建表语句
-- auto-generated definition
create table t_wxuserinfo
(
    id            int auto_increment
        primary key,
    openid        varchar(90)  null,
    nickName      varchar(150) null,
    avatarUrl     varchar(600) null,
    registerDate  datetime     null,
    lastLoginDate datetime     null
);


3.2代码自动生成器(方便我们的自己生成我们的表 带有注释 大家自行修改自己的部分就好)
package yt.test.commom;


import com.baomidou.mybatisplus.generator.FastAutoGenerator;
import com.baomidou.mybatisplus.generator.config.OutputFile;

import java.util.Collections;

/**
 * @since 2022-01-26
 */

public class GeneratorServiceEntity {

    public static String url = "jdbc:mysql://localhost:3306/login?serverTimezone=GMT%2b8";//填写自己的url
    private static final String userName = "root";//自己的userName
    private static final String password = "root";//自己的password
    //
    private static final String outDir = "C:\\Users\\86189\\Downloads\\Music\\test" //选填 填写你自己的项目的路径
            //不用动 写死
            + "\\src\\main\\java\\";
    //这个直接写出 截止到 Application下
    private static final String parentPackage = "com.yt.test";
    // todo 书写你们自己的当前的项目的路径
    private static final String mapperLocation = "C:\\Users\\86189\\Downloads\\Music\\test" +
            //不用动
            "\\src\\main\\resources\\mapper\\";
    // todo 书写你们自己的表名即可
    private static final String tableName = "t_wxuserinfo";

    public static void main(String[] args) {
        generate();
    }

    private static void generate() {
        FastAutoGenerator.create(url, userName, password)
                .globalConfig(builder -> {
                    builder.author("yt") // 设置作者
                            .enableSwagger() // 开启 swagger 模式
                            .fileOverride() // 覆盖已生成文件
                            .outputDir(outDir); // 指定输出目录
                })
                .packageConfig(builder -> {
                    builder.parent(parentPackage) // 设置父包名
                            .moduleName(null) // 设置父包模块名
                            .pathInfo(Collections.singletonMap(OutputFile.mapperXml, mapperLocation)); // 设置mapperXml生成路径
                })
                .strategyConfig(builder -> {
                    builder.entityBuilder().enableLombok();
//                    builder.mapperBuilder().enableMapperAnnotation().build();
                    builder.controllerBuilder().enableHyphenStyle()  // 开启驼峰转连字符
                            .enableRestStyle();  // 开启生成@RestController 控制器
                    builder.addInclude(tableName) // 设置需要生成的表名
                            .addTablePrefix("t_", "tbl_"); // 设置过滤表前缀
                })
//                .templateEngine(new FreemarkerTemplateEngine()) // 使用Freemarker引擎模板,默认的是Velocity引擎模板
                .execute();

    }
}

3.3实体类
package com.sdjzu.yt.entity;
import com.baomidou.mybatisplus.annotation.IdType;
import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;

import com.fasterxml.jackson.databind.annotation.JsonSerialize;
import lombok.Data;

import java.io.Serializable;
import java.util.Date;
@TableName("t_wxUserInfo")
@Data
public class WxUserInfo implements Serializable {


    @TableId(type = IdType.AUTO)
    private Integer id; // 用户编号

    private String openid; // 用户唯一标识


    @TableField("nickName")
    private String nickName; // 用户昵称


    @TableField("avatarUrl")
    private String avatarUrl; // 用户头像图片的 URL


    @TableField("registerDate")
    @JsonSerialize(using = CustomDateTimeSerializer.class)
    private Date registerDate; // 注册日期


    //这里采用的就是我们的自己定义的json的格式 也就是我们的json的返回的形式
    @TableField("lastLoginDate")
    @JsonSerialize(using = CustomDateTimeSerializer.class)
    private Date lastLoginDate; // 最后登录日期


    //wx.login 和 wx.getUserInfo两个方法获取到用户的信息
    @TableField(select = false, exist = false)
    private String code; // 微信用户code 前端传来的



    @TableField("role")
    //用户的角色信息
    private String role;


}

缺少的CustomDateTimeSerializer类
package com.sdjzu.yt.entity;

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;

import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.TimeZone;

public class CustomDateTimeSerializer extends JsonSerializer<Date> {

    @Override
    public void serialize(Date value, JsonGenerator gen, SerializerProvider serializers)
            throws IOException {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        sdf.setTimeZone(TimeZone.getTimeZone("Asia/Shanghai"));
        gen.writeString(sdf.format(value));
    }

}

3.4业务逻辑的书写
servicec层代码
package yt.test.service;

import yt.test.commom.Result;
import yt.test.entity.Wx;
import com.baomidou.mybatisplus.extension.service.IService;

/**
 * <p>
 * 服务类
 * </p>
 *
 * @author yt
 * @since 2022-06-14
 */
public interface IWxService extends IService<Wx> {
    //这个结果类 大家可以随意发挥 符合自己实际开发即可    
    Result Login(Wx wxUserInfo);
}

servicec实现类层代码(核心)
package com.sdjzu.yt.service.impl;

import cn.dev33.satoken.stp.SaLoginConfig;
import cn.dev33.satoken.stp.StpUtil;
import cn.dev33.satoken.util.SaResult;
import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.baomidou.mybatisplus.core.conditions.query.QueryWrapper;
import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
import com.sdjzu.yt.entity.WxUserInfo;
import com.sdjzu.yt.mapper.WxUserInfoMapper;
import com.sdjzu.yt.service.IWxUserInfoService;
import com.sdjzu.yt.util.HttpClientUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.Date;
import java.util.HashMap;
import java.util.Map;

@Service("wxUserInfoService")
public class wxImpl extends ServiceImpl<WxUserInfoMapper, WxUserInfo> implements IWxUserInfoService {
    //定死 不需要修改
    private static final String jscode2sessionUrl = "https://api.weixin.qq.com/sns/jscode2session";
    private static final String appid = "wx3a9ec56a038032c8";    //todo 必改 改成自己的appid
    private static final String secret = "ffdae995a6d35840558552ac65803e4d";//todo 必改 改成自己的密钥
    @Autowired
    private WxUserInfoMapper wxUserInfoMapper;
    @Autowired
    private HttpClientUtil httpClientUtil;

    //实现登陆的逻辑
    @Override
    public SaResult Login(WxUserInfo wxUserInfo) {
        String getMessageUrl = jscode2sessionUrl +
                "?appid=" + appid + "&secret=" +
                secret + "&js_code=" +
                wxUserInfo.getCode() +
                "&grant_type=authorization_code";
        String result = httpClientUtil.sendHttpGet(getMessageUrl);
        JSONObject jsonObject = JSON.parseObject(result);
        String openid = jsonObject.get("openid").toString();

        // todo 至此我们已经获取到openID
        // todo 下面书写自己的业务逻辑 随意发挥

        //todo 这个是我的业务逻辑 可以参考(较简单)
        QueryWrapper<WxUserInfo> wrapper = new QueryWrapper<>();
        wrapper.eq("openid", openid);
        WxUserInfo user = wxUserInfoMapper.selectOne(wrapper);
        if (user == null) {
            System.out.println("插入用户");
            try {
                wxUserInfo.setOpenid(openid);
            } catch (Exception e) {
                e.printStackTrace();
            }
            wxUserInfo.setRegisterDate(new Date());
            wxUserInfo.setLastLoginDate(new Date());
            wxUserInfoMapper.insert(wxUserInfo);
        } else {
            System.out.println("更新用户");
            user.setNickName(wxUserInfo.getNickName());
            user.setAvatarUrl(wxUserInfo.getAvatarUrl());
            user.setLastLoginDate(new Date());
            wxUserInfoMapper.updateById(user);
        }
        //
        StpUtil.login(openid, SaLoginConfig.setExtra(wxUserInfo.getNickName(), wxUserInfo.getAvatarUrl()));
        //这里我们获取到了我们的token 一旦发放我们的token 之后我们的token有效期从这里开始生效
        String token = StpUtil.getTokenValue();
        Map<String, Object> map = new HashMap<>();
        map.put("token", token);
        SaResult map1 = new SaResult(200, "成功", map);
        return map1;
    }

    @Override
    public SaResult UserAuthority(String userRole) {
        return null;
    }

}
