现在运动计步很火,无论是蚂蚁森林,还是微信上都很火爆,本文介绍了微信小程序微信运动步数的实例代码,分享给大家
微信小程序API-微信运动 https://mp.weixin.qq.com/debug/wxadoc/dev/api/we-run.html#wxgetwerundataobject
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。
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')
},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。
$url = 'https://api.weixin.qq.com/sns/jscode2session?appid='.$appid.'&secret='.$appsecret.'&js_code='.$_GET['code'].'&grant_type=authorization_code';
$content = file_get_contents($url);
$content = json_decode($content);
echo $content->session_key;
decryptData($encryptedData,$iv,$data );

print($data . "\n");
} else {
print($errCode . "\n");
