方式1：

childProcess = exec('adb logcat | grep "sqsdk"');
 childProcess.stdout.on("data", (data) => {
            console.log(`${data}`);
        });

到达了maxbuffer便不会输出

方式2：
执行脚本文件：不支持多个平台

方式3：
执行spawn子进程，发现会多出来很多日志
子进程需要关闭父进程来关闭掉

let result = str.search(/sqsdk/);
正则匹配到的位置：1032

获取当前component的实例

代码示例

//main.js
window._vue = new Vue({
  router, render: h => h(App)
}).$mount("#app");

//component组件
mounted() {
      let _this = this;
      getRecentFiles(function(tmpFiles) {
        console.log("tmpFiles:"+tmpFiles);
        //原始数据被reverse
        _this.recentFiles = { ...tmpFiles.reverse() };
        console.log("最近文件1", _this.recentFiles);

        console.log("tmpFiles:"+tmpFiles);
        window._vue.recentFiles = { ...tmpFiles.reverse() };
        console.log("最近文件1", window._vue.recentFiles);
        if (window._vue.recentFiles == _this.recentFiles){
          console.log("相同");
        }else {
          console.log("不同");
        }
      });
      console.log("mounted");
    }
