4.1 wxml
<view class="container">
<text bindtap="doJump" class="jump">跳过{{seconds}}秒</text>
<image class="img" src="/images/bg/splash.png" />
</view>
4.2 js
Page({
data: {
seconds:3
},
doJump(e){
wx.switchTab({
url: '/pages/index/index'
})
},
onLoad(options) {
var instance = setInterval(()=>{
if(this.data.seconds <= 0){
clearInterval(instance)
wx.switchTab({
url: '/pages/index/index',
})
}else{
this.setData({
seconds:this.data.seconds - 1
})
}
},1000)
},

}
4.5 后端加载的欢迎页
4.5.1 表模型
class Welcome(models.Model):
img = models.ImageField(upload_to='welcome', default='slash.png')
order = models.IntegerField()
create_time = models.DateTimeField(auto_now=True)
is_delete = models.BooleanField(default=False)
4.5.2 开启media访问
MEDIA_URL = '/media/'
MEDIA_ROOT=os.path.join(BASE_DIR,'media')
path('media/<path:path>', serve, {'document_root': settings.MEDIA_ROOT})
4.5.3 视图函数
from .models import Welcome
from django.http import JsonResponse
def welcome(requesst):
welcome=Welcome.objects.all().order_by('order').first()
return JsonResponse({'code':100,'msg':'成功','result':{'img':'http://127.0.0.1:8000/media/'+str(welcome.img)}})
4.5.4 微信小程序端
const api = require("../../config/settings.js")
Page({
data: {
img:'http://127.0.0.1:8000/media/welcome/splash3.png',
seconds:3
},
doJump(e){
wx.switchTab({
url: '/pages/index/index'
})
},
onLoad(options) {
wx.request({
url: api.welcome,
method:'GET',
success:(res)=>{
this.setData({
img:res.data.result.img
})
}
})
var instance = setInterval(()=>{
if(this.data.seconds <= 0){
clearInterval(instance)
wx.switchTab({
url: '/pages/index/index',
})
}else{
this.setData({
seconds:this.data.seconds - 1
})
