1. 首先，登錄pc端的微博頁面，并切換到自己微博列表的第一頁（url 應該是 https://weibo.com/YOURNAME/profile...這樣的形式 ）
2. 在 chrome 瀏覽器調試工具的 console 命令行（ chrome如何打開控制臺-百度經驗
   ）中，貼入以下代碼：

const delay = 6180; // 間隔時間
const onlyForward = true; // 僅刪轉發(fā)

const ajwvr = 6;
const cfg = window.$CONFIG;
let pagebar = 0;

function getQuery() {
    const { protocol, host, pathname, search } = document.location;
    const query = search.substr(1).split('&').reduce((obj, item) => {
        const [key, value] = item.split('=');
        obj[key] = value;
        return obj;
    }, Object.create(null));
    return { ...document.location, query: { page: 1, profile_type: 1, ...query } };
}

3. 如果連續(xù)刪除的已發(fā)微博數量較多，官方為防止操作過于頻繁，每隔一段時間就會刪除失敗，這時只要等待即可，腳本會繼續(xù)執(zhí)行
4. 該腳本還很原始，如果條數多，刪除速度會很慢，請耐心使用
5. 刪到最后一頁后，可能需要手動翻回首頁重復若干次
