request in the vue page:

mounted () {
    axios.get("http://v.juhe.cn/toutiao/index", {
      params: {
        key: "ed0b5a46f81b282bd2ce8df1f02225d9"
      }
    })
    .then(function (res) {
      console.log(res);
      this.list = res.result.data
    })
    .catch(function (error) {
      console.log(error);
    });
}

there will be cross-domain errors when using cordova serve android, but there should be no cross-domain errors when packaged into APP?

the cordova-plugin-whitelist plug-in is installed, but it doesn"t work.

debug with chrome://inspect/-sharpdevices, the console reports an error:

I really can"t find out the reason. Please give me some advice.
