button标签详解
index.js
获取code链接
返回openid session_key uinionid(需要绑定微信开放平台)errcode number errMsg等参数的链接
获取uinionid的三种方式
//获取应用实例const app = getApp()Page({data: {code:''",id:''",},//事件处理函数onLoad: function (option) {console.log(option)var that = thiswx.login({success:function(res){that.setData({code:res.code})}})let id = '0'console.log(wx.getStorageSync(id))that.setData({ id: wx.getStorageSync(id)})},//获取用户信息onGotUserInfo: function (res) {console.log(res)//获取的数据有 encryptedData，iv等// 做一个判断是否已经授权然后继续操作var that = this//查看是否授权let id = '0'if (wx.getStorageSync(id)){wx.navigateTo({url: ‘跳转页面的地址’,})}else{wx.request({url: '你的请求地址',method: 'POST',header: {"Content-Type": "application/x-www-form-urlencoded"},data: { 'code': that.data.code, 'encryptedData': res.detail.encryptedData, 'iv': res.detail.iv },success: function (res) {#查看注意事项《1》console.log(res.data)that.setData({ id: res.data})wx.navigateTo({url: ‘跳转页面的地址’,})//查看是否授权let id = '0'wx.setStorageSync(id, res.data) }})}},})
####注意事项《1》如果是用的自带底部导航栏配置 ，用户第一次拒绝授权，再次点击授权允许的时候会报-41001 。原因是code没有更新需要跟新code,解决办法在判断拒绝授权的时候刷新当前页面
if (getCurrentPages().length != 0) {//刷新当前页面的数据getCurrentPages()[getCurrentPages().length - 1].onLoad()}#wx.login需要放在onload里面不要放在onShow里面
进行解码算法
解码文件的下载
下方我对demo.php的改造可以参考 其余两个文件不用改
<?phpinclude_once "wxBizDataCrypt.php";#获取个人信息部分$appid = ‘xxxxxxxxxxxxx';$secret= 'xxxxxxxxxxxxxxxxxxx';$code = $_POST['code'];//是前方获取的code（login组件）$sessionKeyUrl = 'https://api./sns/jscode2session?appid='.$appid.'&secret='.$secret.'&js_code='.$code.'&grant_type=authorization_code';$sessionKey= http_get($sessionKeyUrl);$sessionKey = json_decode($sessionKey,true);$sessionKey = $sessionKey['session_key'];$encryptedData = $_POST['encryptedData'];$iv = $_POST['iv'];function http_get($sessionKeyUrl){$curl = curl_init(); // 启动一个CURL会话curl_setopt($curl, CURLOPT_URL, $sessionKeyUrl);curl_setopt($curl, CURLOPT_HEADER, 0);curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); // 跳过证书检查curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2); // 从证书中检查SSL加密算法是否存在$tmpInfo = curl_exec($curl);//返回api的json对象//关闭URL请求curl_close($curl);return $tmpInfo;}$pc = new WXBizDataCrypt($appid, $sessionKey);$errCode = $pc->decryptData($encryptedData, $iv, $data );if ($errCode == 0) {print($data) //最终数据} else {print($errCode . "\n");}
结果
{"openId": "OPENID","nickName": "NICKNAME","gender": GENDER,"city": "CITY","province": "PROVINCE","country": "COUNTRY","avatarUrl": "AVATARURL","unionId": "UNIONID","watermark":{"appid":"APPID","timestamp":TIMESTAMP}}
查看是否授权 包括自动更新
用到的API: setStorageSync,getStorageSync
在app.js里面
App({onLaunch: function () {//自动更新的设置const updateManager = wx.getUpdateManager()updateManager.onCheckForUpdate(function (res) {// 请求完新版本信息的回调console.log(res.hasUpdate)})updateManager.onUpdateReady(function () {wx.showModal({title: '更新提示',content: '新版本已经准备好，是否重启应用？',success: function (res) {if (res.confirm) {// 新的版本已经下载好，调用 applyUpdate 应用新版本并重启updateManager.applyUpdate()}}})})updateManager.onUpdateFailed(function () {// 新的版本下载失败wx.showModal({title: '更新提示',content: '新版本下载失败',showCancel: false})})let id = '0' //首先给个默认值 否则报错wx.getStorageSync(id)console.log(wx.getStorageSync(id))},globalData: {id : ''}})
