将chrome页面的变量保存到本地

在chrome的控制台中粘贴并运行如下代码:

(function(console) {
    console.save = function(data, filename) {
        if (!data) {
            console.error('Console.save: No data')
            return;
        }
        if (!filename) filename = 'console.json'
        if (typeof data === 'object') {
            data = JSON.stringify(data, undefined, 4)
        }
        var blob = new Blob([data], {
                type: 'text/json'
            }),
            e = document.createEvent('MouseEvents'),
            a = document.createElement('a')
        a.download = filename
        a.href = window.URL.createObjectURL(blob)
        a.dataset.downloadurl = ['text/json', a.download, a.href].join(':')
        e.initMouseEvent('click', true, false, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null)
        a.dispatchEvent(e)
    }
    return 'success'
})(console)

使用范例:

然后运行如下代码:

fetch('https://feed.sina.com.cn/api/roll/get?pageid=121&lid=1356&num=20&versionNumber=1.2.4&page=125&encode=utf-8&_=1600564853163')
    .then(res=>{
        res.json().then(r=>{
            console.save(r, 'result.json')
        })
    });
