微信小程序手机号码授权登录

一、微信小程序开发

目前个人的小程序无法使用手机号码授权登录，可以使用测试号进行开发

二、使用步骤

1.前端代码

代码如下（示例）：

<button open-type="getPhoneNumber" bindgetphonenumber="getUserPhoneNumber">立即登录button>

Page({

getUserPhoneNumber(event) {
    if(event.detail.errMsg != "getPhoneNumber:ok") {
      // 授权失败
      return false;
    }
    // 发起请求，进行授权登录
    wx.request({
      url: app.globalData.basePath + "/system/applet/login",
      data: {
        phoneCode: event.detail.code
      },
      method:"POST",
      success: res => {
        console.log(res.data);
        wx.setStorageSync("applet", res.data);
      }
    })
  }
}}

2.后台配置

# 小程序配置
applet:
  appId: wx53fda****c6b0a3
  appSecret: ade99d6dca77****f52fecd5d35039b5
  grantType: authorization_code

3.后台代码

代码如下（示例）：

package com.ruoyi.system.domain.io;

public class AppletLoginInput {

    private String phoneCode;

    private String iv;

    private String encryptedData;

    public String getPhoneCode() {
        return phoneCode;
    }

    public void setPhoneCode(String phoneCode) {
        this.phoneCode = phoneCode;
    }

    public String getIv() {
        return iv;
    }

    public void setIv(String iv) {
        this.iv = iv;
    }

    public String getEncryptedData() {
        return encryptedData;
    }

    public void setEncryptedData(String encryptedData) {
        this.encryptedData = encryptedData;
    }
}

package com.ruoyi.system.domain.io;

public class AppletLoginOutput {

    /**
     * token信息
     */
    private String token;

    public String getToken() {
        return token;
    }

    public void setToken(String token) {
        this.token = token;
    }
}

/**
 * 微信小程序手机号码授权登录
 * @param input
 */
@Anonymous
@PostMapping("/login")
public AppletLoginOutput login(@RequestBody AppletLoginInput input) {
    AppletLoginOutput appletLoginOutput = new AppletLoginOutput();
    // 首先获取最新的token信息
    String tokenParam = "appid=" + appletConfig.getAppId() + "&secret=" + appletConfig.getAppSecret() + "&grant_type=client_credential";
    String tokenResult = HttpUtils.sendGet("https://api.weixin.qq.com/cgi-bin/token", tokenParam);
    JSONObject tokenJSONObject = JSONObject.parseObject(tokenResult);

    // 通过登录信息获取用户的手机号码
    // 获取token 信息
    String body = "{\"code\": \"" + input.getPhoneCode() + "\"}";
    HttpRequest post = HttpUtil.createPost("https://api.weixin.qq.com/wxa/business/getuserphonenumber?access_token=" + tokenJSONObject.getString("access_token"));
    post.header("Content-Type", "application/json");
    post.body(body);
    HttpResponse execute = post.execute();
    AppletResultModel resultModel = JSONObject.parseObject(execute.body(), AppletResultModel.class);
    String jsonString = JSONObject.toJSONString(resultModel);
    System.out.println(jsonString);
    // {"errcode":0,"errmsg":"ok","phone_info":{"countryCode":"86","phoneNumber":"178****3721","purePhoneNumber":"178****3721","watermark":{"appid":"wx53fda****1c6b0a3","timestamp":1754865784}}}
    return appletLoginOutput;
}
