java服务器端集成微信小程序

   weixin-java-tools是轻量性的，扩张性比较强的微信应用第三方插件，今天我给大家讲一下如何在spring boot应用中集成微信小程序相关API。

   1.pom文件配置 

	com.github.binarywang
	weixin-java-miniapp
	${weixin-java-miniapp.version}

  2.创建contoller供外部调用

package com.cloud.controller;

import cn.binarywang.wx.miniapp.api.WxMaService;
import cn.binarywang.wx.miniapp.bean.WxMaJscode2SessionResult;
import cn.binarywang.wx.miniapp.bean.WxMaPhoneNumberInfo;
import cn.binarywang.wx.miniapp.bean.WxMaUserInfo;
import com.alibaba.fastjson.JSONObject;
import com.yycunluo.cloud.service.WeixinServiceFactory;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.core.env.Environment;
import org.springframework.web.bind.annotation.*;
/**
 * 微信小程序用户接口
 *
 *
 */
@RestController
@RequestMapping("/maUser")
public class WxMaUserController {
    private final Logger logger = LoggerFactory.getLogger(this.getClass());
    @Autowired
    private Environment environment;
    /**
     * 登陆接口
     */
    @RequestMapping(value = "/getUserByCode",method = RequestMethod.POST)
    public JSONObject login(@RequestBody JSONObject inData) {
        String code = inData.getString("code");
        String appId = inData.getString("appId");
        JSONObject json = new JSONObject();
        try {
            final WxMaService wxMaService = WeixinServiceFactory.getWxMaService(appId, environment);
            WxMaJscode2SessionResult session = wxMaService.getUserService().getSessionInfo(code);
            json.put("code", 0);
            json.put("message", "success");
            json.put("data", session);
        } catch (Exception e) {
            logger.error("调用微信服务器出现异常", e);
            json.put("code", 1812041738);
            json.put("message", "获取微信用户数据失败");
        }
        return json;
    }
    /**
     *
     * 获取用户信息接口
     *
     */
    @GetMapping("/getUserInfo")
    public JSONObject getUserInfo(@RequestBody JSONObject inData){
        JSONObject json = new JSONObject();
        try {
            String appId = inData.getString("appId");
            String sessionKey = inData.getString("sessionKey");
            String signature = inData.getString("signature");
            String rawData = inData.getString("rawData");
            String encryptedData = inData.getString("encryptedData");
            String iv = inData.getString("iv");
            final WxMaService wxMaService = WeixinServiceFactory.getWxMaService(appId, environment);
            // 用户信息校验
            if (!wxMaService.getUserService().checkUserInfo(sessionKey, rawData, signature)) {
                json.put("code",1812041739);
                json.put("message", "获取用户信息接口出错");
                return json;
            }
            // 解密用户信息
            WxMaUserInfo userInfo = wxMaService.getUserService().getUserInfo(sessionKey, encryptedData, iv);
            json.put("code", 0);
            json.put("message", "success");
            json.put("data", userInfo);
        }catch (Exception e) {
            logger.error("调用微信服务器出现异常", e);
            json.put("code", 1812041738);
            json.put("message", "获取微信用户数据失败");
        }
        return json;
    }
    /**
     *
     * 获取用户绑定手机号信息
     *
     */
    @GetMapping("/getUserPhone")
    public JSONObject getUserPhone(@RequestBody JSONObject inData) {
        JSONObject json = new JSONObject();
        try {
            String appId = inData.getString("appId");
            String sessionKey = inData.getString("sessionKey");
            String signature = inData.getString("signature");
            String rawData = inData.getString("rawData");
            String encryptedData = inData.getString("encryptedData");
            String iv = inData.getString("iv");
            final WxMaService wxMaService = WeixinServiceFactory.getWxMaService(appId, environment);
            // 用户信息校验
            if (!wxMaService.getUserService().checkUserInfo(sessionKey, rawData, signature)) {
                json.put("code",1812050942);
                json.put("message", "获取用户信息接口出错");
                return json;
            }
            // 解密用户信息
            WxMaPhoneNumberInfo wxMaPhoneNumberInfo = wxMaService.getUserService().getPhoneNoInfo(sessionKey, encryptedData, iv);
            json.put("code", 0);
            json.put("message", "success");
            json.put("data", wxMaPhoneNumberInfo);
        }catch (Exception e) {
            logger.error("调用微信服务器出现异常", e);
            json.put("code", 1812050942);
            json.put("message", "获取微信用户数据失败");
        }
        return json;
    }
}

 3.通过接口映射的接口可以进行访问。
