微信小程序API-微信运动

思路：wx.login获取的code请求获取的session_key，wx.getWeRunData获取的iv,encryptData，将它们一起发送到后台解密就行了。

安全顾虑，因为只是示例所以直接传递session_key了，为了安全最好按照下图的方式加密后存储到redis中再传递key。

小程序端代码 get3rdSession: function () { let that = this wx.request({ url: 'https://localhost/login.php', data: { code: this.data.code }, method: 'GET', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT success: function (res) { var sessionId = res.data; that.setData({ sessionId: sessionId }) wx.setStorageSync('sessionId', sessionId) that.decodeUserInfo() } }) }, decodeUserInfo: function () { let that = this wx.request({ url: 'https://localhost/decrypt.php', data: { encryptedData: that.data.encryptedData, iv: that.data.iv, session: wx.getStorageSync('sessionId') }, method: 'GET', // OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT // header: {}, // 设置请求的 header success: function (res) { let todayStep = res.data.stepInfoList.pop() that.setData({ step: todayStep.step }); } }) }, onLoad: function () { let that = this wx.login({ success: function (res) { let code = res.code that.setData({ code: code }) wx.getWeRunData({//解密微信运动 success(res) { const wRunEncryptedData = res.encryptedData that.setData({ encryptedData: wRunEncryptedData }) that.setData({ iv: res.iv }) that.get3rdSession()//解密请求函数 } }) } }) }

后台这使用的是官方PHP版本Demo：先处理login的请求，login.php直接返回session_key，然后再一起请求decrypt.php进行解密。

login.php部分代码 $appid = '你的appid'; $appsecret = '你的appsecret'; $url = 'https://api.weixin.qq.com/sns/jscode2session?appid='.$appid.'&secret='.$appsecret.'&js_code='.$_GET['code'].'&grant_type=authorization_code'; $content = file_get_contents($url); $content = json_decode($content); echo $content->session_key; decrypt.php部分代码 $pc = new WXBizDataCrypt($appid, $sessionKey); $errCode = $pc->decryptData($encryptedData, $iv, $data ); if ($errCode == 0) { print($data . "\n"); } else { print($errCode . "\n"); }
