1.获取过程及需要的参数，图已经很明显，这个是在网上拿别人的图，写的很好很到位，就不一一解释，比较我也是菜鸟
2，在小程序这边，我们需要用 wx.login来给后台传code（因为微信小程序，不支持在小程序页面使用appid和secret,防止你的信息丢失，所以正式版只能从后台调用接口），注意code只有十分钟有效期，而且每次访问code都是变化的（微信这么写的）
后台代码
public class WxStepController { private String appid = "你的appid"; private String secret = "你的secret"; private String url = "https://api.weixin.qq.com/sns/jscode2session?appid=" + appid + "&secret=" + secret + "&js_code="; private String url0 = "&grant_type=authorization_code"; //我自己的注入，------------------------------------ @Autowired private MemberMapper ms; @Autowired 虚线内的你们可以不要 private WalkStepMapper ws;------------------------------------------------------ protected static final Logger logger = LoggerFactory.getLogger(WxStepController.class); @ApiOperation(value = "微信登录") @ApiImplicitParam(name = "code",value = "微信code",required = true, dataType = "int") //两行为swagger的注解，可以不要 @RequestMapping("/onlogin") public String login(String code){ String oppid=""; JSONObject oppidObj=null; try { oppid = new HttpRequestor().doGet(url+code+url0); //url+code+url0 oppidObj =JSONObject.fromObject(oppid); System.out.println(oppidObj); } catch (Exception e) { e.printStackTrace(); } logger.debug("获取到的json串"+oppid); Gson gson = new Gson(); return gson.toJson(oppidObj); }这样的话，就能获取到用户session_key，openid（对于一个公众号唯一），
3.这时候，我们需要用wx.getWeRunData来获取微信运动的数据，以及加密方式等，用来解密微信运动数据数据
其中，token是用来验证用户是否登录，和传递用户信息的，相信很多都用，因为我这个是app跳小程序，所以传token，如果只是小程序的，传openid即可，因为这就是唯一标识符，openid在上面的json已经获取到
解密方法类AES，直接copy别人的

这就算完成了，只需要把返回结果，放进data，然后页面调用就行，我把整体代码再贴一遍，免的你们看着乱
完整代码
在data中，加上 runData:{}即可
var that = this; wx.login({ success: function(res) { // 发送 res.code 到后台换取 openId, sessionKey, unionId //if (res.code) { wx.request({ url: 'https://你的服务器地址/onlogin', //本地调试，是获取不到code的，所以要实现，还是得传服务 data: { "code": res.code }, header: { 'content-type': 'application/json' // 默认值 }, success: function (res) { console.log(res.data) console.log("sessionkey--" + res.data.session_key) //2、调用小程序API: wx.getWeRunData获取微信运动数据（加密的）； wx.getWeRunData({ success(resRun) { const encryptedData = resRun console.info(resRun); //3、解密步骤2的数据； wx.request({ url: 'https://你的服务器地址/decrypt', //记得更改 data: { encryptedData: resRun.encryptedData, iv: resRun.iv, sessionKey: res.data.session_key, token:'用户token,如果你只是小程序开发，传openid即：res.data.openid',days: 3 //传要协调的天数 }, method: 'GET', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT // header: {}, // 设置请求的 header success: function (resDecrypt) { var runData = JSON.parse(resDecrypt.data.userInfo) console.info(runData); if (runData.stepInfoList) { runData.stepInfoList = runData.stepInfoList.reverse() for (var i in runData.stepInfoList) { //给数据加上时间，格式呢，在你的util.js下面写，建微信小程序项目的时候就有，import进来就行，不要也可以 runData.stepInfoList[i].date = util.formatTime(new Date(runData.stepInfoList[i].timestamp * 1000)) } that.setData({ runData: runData.stepInfoList }); } } }); } }) } }) //} else { // console.log('获取用户登录态失败！' + res.errMsg) //} } })页面显示部分（我只取了当天数据，所以下标是0，如果要显示30天数据，用wx:for-items={{runData}}）
后台代码，上面都有，只需要把我的存储步数的类，换成你的即可 （TWalk）数据存储和查询部分，根据自己情况即可，第一次在这上面发，写的不好，大家见谅，有问题可以互动的哦，希望能帮到大家，方法上面那些@Api什么的，都是swagger的注解，前后端分离时候，为前后知道接口作用和要传的参数用的
