【将数据存储在本地缓存】wx.setStorage
【读取本地缓存】wx.getStorage
以手机号+密码登录为例,把登录成功返回的token值存储在本地缓存中,然后读取缓存中的token:
login.php:
<?php header("Content-type:text/html;charset=utf-8"); $arr = array("state"=>0,"data"=>array(),"msg"=>''); $phone = $_POST['phone']; $password = $_POST['password']; if($phone && $password){ //省略验证...... //返回登录token $tokenstr = 'liweishan666'; $token = $phone.time().$tokenstr;//省略加密 $arr['state'] = 1; $arr['msg'] = '登录成功'; $arr['data']['token'] = $token; }else{ $arr['msg'] = '参数错误'; } echo json_encode($arr); die;
login.wxml:
<form bindsubmit="formSubmit" bindreset="formReset"> <view> 手机号:<input type="text" name="phone" placeholder="请输入账号" confirm-type="done" /> 密码:<input password type="number" name="password" placeholder="请输入6位密码" maxlength="6" /> </view> <view class="btn-area"> <button formType="submit">登录</button> </view> <view class="btn-area"> <button bindtap="gettoken">读取缓存token</button> </view> <view class="btn-area">{{token}}</view> </form>
login.js:
Page({ formSubmit: function (e) { wx.request({ url: 'https://www.msllws.top/login.php', data: { 'phone': e.detail.value.phone, 'password': e.detail.value.password }, method: 'POST', header: { 'Content-Type': 'application/x-www-form-urlencoded' }, success: function (res) { console.log(res.data); //以键值对的形式存储到本地缓存 wx.setStorage({ key: "token", data: res.data.data.token }) }, fail: function () { }, complete: function () { } }) }, gettoken: function (e) { var that = this wx.getStorage({ key: 'token', success: function (res) { that.setData({'token': res.data}) }, fail: function () { }, complete: function () { } }) } })
实现缓存的存储和读取:
【从缓存中移除指定数据】wx.removeStorage
wx.removeStorage({ key: 'token', success (res) { console.log(res.data) } })
【清除全部缓存数据】wx.clearStorage
wx.clearStorage()
