背景

笔者为了一个简单的需求：即不同主体间的小程序跳转，举个例子，我的小程序想直接跳转某盘小程序里面实现分享，这样有更好的用户体验。碍于无法获取跳转参数的设置方法，遂做笔记以证笔者的尝试历程。

方案

获取小程序源码，首先可以肯定这个方案是可行的的。

笔者截取了一段反编译命令执行过程

可能存在文件残缺的问题，但是最终是成功获取到源码的，那么接下来
我们来阐述一下该过程中需要注意的几个关键点。

第一点：配置环境变量

安装将node.js 和 npm 后，全部加入环境变量
笔者的环境变量为

npm ：D:\nodejs\node_modules\npm\node_modules
node：D:\nodejs

npm

第二点：

连接DDMS

访问到 /data/data/com.tencent.mm/MicroMsg/{User}/appbrand/pkg
导出应该都会吧？
DDMS

ADB桥接

我这里是MUMU模拟器端口号为 7555，夜神和海马都有自己的端口号，这里之所以用模拟器是因为它可以获取root权限，不然DDMS获取不到/data/data/下的文件

第三点：新建下载

新建

笔者直接在桌面创建文件夹
C:\Users\Administrator\Desktop\WeiXin

下载

然后去https://github.com/qwerty472123/wxappUnpacker下载，当然也可以直接git clone 拉下来。

放在C:\Users\Administrator\Desktop\WeiXin文件夹下面然后解压，可以看到和之前下载下来的.wxapkg放一起，主要是为了方便操作.
下载位置

Shift+右键打开命令行
CMD

最后不出意外跟上面命令一样一次成功。

第四点：跳转

API 地址

wx.navigateToMiniProgram({
  appId: 'xxxxx',
  path: 'pages/xxxxx_share/share',
  extraData: {
  },
  envVersion: 'develop',
  success(res) {
    // 打开成功
  }
})

path

app.json找到的分享路径
share

appid

可参考https://blog.csdn.net/qq_20330595/article/details/86496433#2_18

extraData

extraData
看对方怎么取得你就怎么传。
