需要sellerId=50852803的50852803

獲取數(shù)據(jù)地址 https://acs.m.taobao.com/h5/mtop.taobao.social.feed.aggregate/1.0/?appKey=12574478&t=1582778795899&sign=367a770e5a56cfaafc350da1da6b7d76&api=mtop.taobao.social.feed.aggregate&v=1.0&timeout=300000&timer=300000&type=jsonp&dataType=jsonp&callback=mtopjsonp1&data=%7B%22params%22%3A%22%7B%5C%22nodeId%5C%22%3A%5C%22%5C%22%2C%5C%22sellerId%5C%22%3A%5C%2250852803%5C%22%7D%22%2C%22cursor%22%3A%221%22%2C%22pageNum%22%3A%221%22%2C%22pageId%22%3A5703%2C%22env%22%3A%221%22%7D 其中 t為當(dāng)前時間戳 sign 為 (token + "&" + t + "&" + appKey + "&" + data) 這幾個參數(shù)拼接后轉(zhuǎn)成MD5我們需要獲取的就只有token,而token是服務(wù)器傳過來的 所以偽造一次訪問獲取返回的token,然后再訪問數(shù)據(jù)
