しばらく預かる

axios要求バックエンドデータ

this.$axios({
	url: 'http://119.29.140.134/api/city',
	method: 'post',
	headers: {
		'Content-Type': 'application/json'
	}
})
.then(function (response) {
  console.log(response);
})
.catch(function (error) {
  console.log(error);
}); 

データエクスポート

this.$api.getPSQAddressInfo().then(res => {
	var FileSaver = require('file-saver');
	var content = JSON.stringify(res.data);
	var blob = new Blob([content ], {type: "text/plain;charset=utf-8"}); 
	FileSaver.saveAs(blob, "address.json");
})
