在我们正常的浏览网站的时候,未登录点击vip专区的时候,需要登录,登录后还会回到最初要进入的网站,这就是页面重定向,在小程序里面也需要完成这样的功能。源码:https://github.com/limingios/wxProgram.git 中No.15
小程序代码
对于搜索,可以类似淘宝的功能,无需登录就可以进行搜索,但是文件上传这个功能就需要进行登录后才可以进行上传,登录后在跳转到原来的页面进行操作。
- 增加data中的默认页面对象,本页面的回调地址
var videoUtils = require('../../utils/videoUtils.js')
const app = getApp()
Page({
data: {
cover:'cover',
videoContext:"",
videoInfo:{},
videId:'',
src:''
},
showSearch:function(){
wx.navigateTo({
url: '../videoSearch/videoSearch',
})
},
onLoad:function(params){
var me = this;
me.videoContext = wx.createVideoContext('myVideo', me);
var videoInfo = JSON.parse(params.videoInfo);
var videoWidth = videoInfo.videoWidth;
var videoHeight = videoInfo.videoHeight;
var cover = 'cover';
if (videoWidth > videoHeight){
cover = '';
}
me.setData({
videId: videoInfo.id,
src: app.serverUrl + videoInfo.videoPath,
videoInfo: videoInfo,
cover: cover
})
},
showIndex:function(){
wx.redirectTo({
url: '../index/index',
})
},
onShow:function(){
var me = this;
me.videoContext.play();
},
onHide:function(){
var me = this;
me.videoContext.pause();
},
upload:function(){
var me = this;
var userInfo = app.getGlobalUserInfo();
var videoInfo = JSON.stringify(me.data.videoInfo);
var realUrl = '../videoInfo/videoInfo#videoInfo@' + videoInfo;
if (userInfo.id == '' || userInfo.id == undefined) {
wx.navigateTo({
url: '../userLogin/userLogin?realUrl=' + realUrl,
})
} else {
videoUtils.uploadVideo();
}
},
showMine: function () {
var me = this;
var userInfo = app.getGlobalUserInfo();
var videoInfo = JSON.parse
if (userInfo.id == '' || userInfo.id == undefined){
wx.navigateTo({
url: '../userLogin/userLogin',
})
}else{
wx.navigateTo({
url: '../mine/mine',
})
}
},
})
登录页面的解析控制
const app = getApp()
Page({
data: {
realUrl:''
},
onLoad:function(params){
var realUrl = params.realUrl;
var me = this;
realUrl = realUrl.replace(/#/g,"?");
realUrl = realUrl.replace(/@/g, "=");
me.setData({
realUrl: realUrl
})
},
doLogin: function (e) {
var formObject = e.detail.value;
var username = formObject.username;
var password = formObject.password;
var me = this;
// 简单验证
if (username.length == 0 || password.length == 0) {
wx.showToast({
title: '用户名或密码不能为空',
icon: 'none',
duration: 3000
})
} else {
wx.showLoading({
title: '正在登录中。。。'
});
wx.request({
url: app.serverUrl + "/login",
method: "POST",
data: {
username: username,
password: password
},
header: {
'content-type': 'application/json' // 默认值
},
success: function (res) {
console.log(res.data);
var status = res.data.status;
wx.hideLoading();
if (status == 200) {
wx.showToast({
title: "用户登陆成功~!",
icon: 'none',
duration: 3000
})
// app.userInfo = res.data.data;
app.setGlobalUserInfo(res.data.data);
var realUrl = me.data.realUrl;
if (realUrl != null && realUrl != '' && realUrl != undefined){
wx.redirectTo({
url: realUrl,
})
}else{
wx.redirectTo({
url: '../mine/mine',
})
}
} else if (status == 500) {
wx.showToast({
title: res.data.msg,
icon: 'none',
duration: 3000
})
}
}
})
}
},
goRegisterPage: function (e) {
wx.redirectTo({
url: '../userRegister/userRegister',
})
}
})
PS:页面重定向只是一种手段,有很多是通过后台的方式来进行控制的,下次给老铁说下springboot的拦截器。
