Android 动态配置域名

Posted 2023-02-27 左郁

应用场景

开发测试过程中，一般会涉及到多个环境测试，例如：开发环境，alpha环境，beta环境，正式环境，测试人员在测试过程中，如果想要查看其他环境的数据，就需要重新安装apk包，所以动态配置域名会显得很方便，不用重新打包，应用内一键切换测试环境

效果展示

1. 入口：做了一个彩蛋功能，标题栏连续点击5次进入，入口可添加在任意你想加的地方
2. 身份验证：这里加了一个判断，方便开发
   • release包需要输入暗号，暗号是当前的日期，格式为yyyyMMdd，eg-20210618，暗号正确，则进入域名配置页面；
   • debug包直接进入域名配置页面
3. 域名配置：支持的相关操作
   • 新增
   • 选择
   • 删除

实现方式：框架集成

已经集成ZyFrame框架的小伙伴只需要调用两句话

1. MyApplication中配置

val defaultHost = "http://10.0.0.110:8088"  //默认域名
ZyConfig.HOST = SpUtil.get(HostKey.host_fileName).getString(HostKey.host_config, defaultHost)

2. 入口点击事件调用

HostSetUtil.displayEggs(this)

实现方式：源码

1. HostSetUtil 域名配置入口彩蛋工具类

object HostSetUtil 
    /**
     * 存放点击事件次数
     */
    private var mHits: LongArray? = null

    /**
     * 测试彩蛋
     */
    fun displayEggs(context: Context) 
        if (mHits == null) 
            mHits = LongArray(3)
        

        mHits?.let 
            System.arraycopy(mHits ?: longArrayOf(), 1, mHits, 0, it.size - 1)
            it[it.size - 1] = SystemClock.uptimeMillis()
            if (SystemClock.uptimeMillis() - it[0] <= 5000) //5秒内连续点击。
                mHits = null
                val isApkInDebug = context.applicationInfo.flags and ApplicationInfo.FLAG_DEBUGGABLE != 0
                if (isApkInDebug) 
                    HostSetDialog(context).show()
                 else 
                    showAdminDialog(context)
                
            
        
    

    /**
     * 展示管理员权限对话框
     */
     private fun showAdminDialog(context: Context) 
        val view = View.inflate(context, R.layout.dialog_host_pwd, null)
        val dialog = AlertDialog.Builder(context)
            .setTitle("身份验证")
            .setView(view)
            .create()

        dialog.setCanceledOnTouchOutside(false)
        dialog.setCancelable(true)
        dialog.show()

        val cancelBtn = view.findViewById<Button>(R.id.btn_cancel)
        val confirmBtn = view.findViewById<Button>(R.id.btn_confirm)
        val inputEditText = view.findViewById<EditText>(R.id.et_input)
        cancelBtn.setOnClickListener 
            dialog.dismiss()
        
        confirmBtn.setOnClickListener 
            val password = StringUtil.getCurrentTime("yyyyMMdd")
            if (password == inputEditText.text.toString()) 
                HostSetDialog(context).show()
             else 
                ToastUtil.show("身份验证失败")
            
            dialog.dismiss()
