最近客户做的一个微信小程序，可以原来的开发者忘记给他源文件了，只能通过反编译uniapp找回原来的代码，特此记录一下反编译的过程

举例：

<view class="data-v-5310fc90">
    <u-sticky bind:__l="__l" class="data-v-5310fc90" vueId="6199cf00-1" vueSlots="{{['default']}}">
        <view class="u-border-bottom echo-top-tabsheight echo-bg-white data-v-5310fc90">
            <u-tabs bind:__l="__l" bind:click="__e" class="data-v-5310fc90" current="{{tabscurrent}}" data-event-opts="{{[ [ '^click',[ ['tabsChange'] ] ] ]}}" list="{{tabslist}}" vueId="{{'6199cf00-2'+','+'6199cf00-1'}}"></u-tabs>
        </view>
    </u-sticky>
    <u-empty bind:__l="__l" class="data-v-5310fc90" icon="/static/empty/data.png" iconSize="300" marginTop="50" mode="data" show="{{pempty}}" vueId="6199cf00-3"></u-empty>
    <block wx:if="{{pempty==false}}">
        <view class="data-v-5310fc90" wx:if="{{swiperlist!=null&&cateid==0}}">
            <u-swiper bind:__l="__l" bind:click="__e" circular="{{true}}" class="data-v-5310fc90" data-event-opts="{{[ [ '^click',[ ['goSwiper'] ] ] ]}}" keyName="tilpic" list="{{swiperlist}}" vueId="6199cf00-4"></u-swiper>
        </view>
        <navigator class="data-v-5310fc90" url="{{'/pages/notice/detail?id='+item.id}}" wx:for="{{plist}}" wx:key="id">
            <view class="u-flex u-flex-nowrap u-row-between u-padding-30 u-border-bottom echo-col-stretch data-v-5310fc90">
                <view class="u-flex-1 u-flex u-flex-wrap echo-row-acontent data-v-5310fc90">
                    <view class="u-line-2 u-font-16 data-v-5310fc90">{{item.title}}</view>
                    <view class="u-flex u-flex-nowrap u-row-between u-font-12 u-light-color echo-width-fill u-padding-top-20 data-v-5310fc90">
                        <view class="data-v-5310fc90">{{item.mediaNoticeCate.name}}</view>
                        <view class="data-v-5310fc90" wx:if="{{item.priority>0}}">置顶</view>
                    </view>
                </view>
            </view>
        </navigator>
        <view class="u-padding-top-20 u-padding-bottom-40 data-v-5310fc90">
            <u-loadmore bind:__l="__l" class="data-v-5310fc90" status="{{pstatus}}" vueId="6199cf00-5"></u-loadmore>
        </view>
    </block>
    <echo-tabbar bind:__l="__l" class="data-v-5310fc90" tabber="{{vuex_tabbar}}" value="{{nowpage}}" vueId="6199cf00-6"></echo-tabbar>
</view>

编译后的代码：

<template>
	<view>
		<u-sticky vueId="6199cf00-1" :vueSlots="['default']" customNavHeight="0px" >
			<view class="u-border-bottom echo-top-tabsheight echo-bg-white data-v-5310fc90" >

			</view>
		</u-sticky>
		<u-empty icon="/static/empty/data.png" iconSize="300" marginTop="50" mode="data" :show="pempty" ></u-empty>
		<block v-if="pempty==false">

</style>

第一步 移除一些没有用的事件

bind:__l="__l"

第二步 将非标签里面的{{}}里面的转变为 vue 事件 如 

wx:if="{{pempty==false}}"
转为
v-if ="pempty==false"

第三步 将小程序.js里面的onlod onShareAppMessage onShareTimeline onPullDownRefresh methods 等常用得到方法 移植到uniapp里面去 这些方法里面很容易替换 一般替换一个this 一个特殊定义的方法如uni
