以前給客戶寫(xiě)的一個(gè)批量采集軟件失效了，今天又過(guò)來(lái)找我我就看了一下，作者采集那里沒(méi)有問(wèn)題，主要是出現(xiàn)在視頻解析那里，以前的解析接口失效了。

客戶那邊是做視頻采集搬運(yùn)的，UC大魚(yú)的視頻質(zhì)量還不錯(cuò)，沒(méi)有水印，記錄一下過(guò)程。

首先從手機(jī)UC瀏覽器分享了一個(gè)作者鏈接過(guò)來(lái)：

http://a.mp.uc.cn/media.html?mid=eafce118a8d04a7fb49edb26e67a16f4&client=ucweb&uc_param_str=frdnsnpfvecpntnwprdsssnikt&uc_biz_str=S:custom%7CC:iflow_ncmt

翻了一下頁(yè)面是分頁(yè)加載的，這種一般都是以Json的形式返回?cái)?shù)據(jù)。

打開(kāi)控制臺(tái)切換到network頁(yè)看一下網(wǎng)頁(yè)請(qǐng)求，這里我有一個(gè)小技巧，一般這種分頁(yè)加載的網(wǎng)頁(yè)我會(huì)先嘗試過(guò)濾一下“page=”字符看一下。

過(guò)濾”page=”字符接口一下子就出來(lái)了：

http://ff.dayu.com/contents/author/eafce118a8d04a7fb49edb26e67a16f4?biz_id=1002&_size=8&_page=1&_order_type=published_at&status=1&_fetch=1&uc_param_str=frdnsnpfvecpntnwprdsssnikt&_=1547577957727

接口請(qǐng)求的時(shí)候主要注意一下下面兩個(gè)參數(shù)，其他默認(rèn)就好。

eafce118a8d04a7fb49edb26e67a16f4 作者ID

page= 分頁(yè)

以上UC大魚(yú)作者的所有視頻鏈接都采集出來(lái)了，接下來(lái)就是把視頻直鏈解析出來(lái)。

我們先從作者頁(yè)打開(kāi)一個(gè)視頻播放頁(yè)面，刷新攔截一下看視頻鏈接是從哪個(gè)接口反回來(lái)的。

http://v.mp.uc.cn/video.html?uc_param_str=frdnsnpfvecpntnwprdssskt&from=media#!wm_cid=267399668026835968!!wm_aid=26fa9499c6dd453ebbfc4880b71aaa75!!wm_id=eafce118a8d04a7fb49edb26e67a16f4

我翻了一下請(qǐng)求發(fā)現(xiàn)他的視頻鏈接是從下面接口反回來(lái)的：

http://v.mp.uc.cn/api/vps?token=Hh%2FdqhK4JBpmDIcJ9CLIWQ%3D%3D&ums_id=97aff448e4250d3d&wm_cid=267399668026835968&wm_id=eafce118a8d04a7fb49edb26e67a16f4

有幾個(gè)亂碼看著不方便，Url解碼一下得到下面數(shù)據(jù)：

http://v.mp.uc.cn/api/vps?token=Hh/dqhK4JBpmDIcJ9CLIWQ==&ums_id=97aff448e4250d3d&wm_cid=267399668026835968&wm_id=eafce118a8d04a7fb49edb26e67a16f4

接口返回了以下數(shù)據(jù)：

{"status":0,"message":"","data":{"url":"http://dy-frontend.video.ums.uc.cn/w/1547547793/video/wemedia/eafce118a8d04a7fb49edb26e67a16f4/444065d12d690e266b5493b90e514f99-1337752270-6-0-2.mp4?auth_key=1547581955-b0bca68f99dc4b42a0c79e978259fea2-0-504c180f7f177d2423bb13078f54a940","duration":196,"size":"21057680","sign":"db4c7d3ccc6a5ee0729a7c24da432ac3"}}

這個(gè)接口有四個(gè)參數(shù)：

token=Hh/dqhK4JBpmDIcJ9CLIWQ==

ums_id=97aff448e4250d3d

wm_cid=267399668026835968

wm_id=eafce118a8d04a7fb49edb26e67a16f4

這些參數(shù)是從哪來(lái)的一般來(lái)說(shuō)我都會(huì)先嘗試搜索一下網(wǎng)頁(yè)源碼，這里我沒(méi)有搜索到，還是得往前面看一下是不是從別的接口返回來(lái)的。（這里我說(shuō)一下抓包我推薦用Fiddler，使用Fiddler全局搜索很容易能搜索到這些參數(shù)是哪個(gè)接口返回的，就不用像我這樣子一個(gè)接口一個(gè)接口去看，我因?yàn)槭窃诶霞移齐娔X用不了Fiddler所以就只能用瀏覽器的開(kāi)發(fā)工具。）

往前面翻了一下發(fā)現(xiàn)除了token,其他幾個(gè)參數(shù)都在下面這個(gè)接口：

http://ff.dayu.com/contents/267399668026835968?biz_id=1002&_fetch_author=1&_fetch_incrs=1

訪問(wèn)后返回了下面數(shù)據(jù)：

現(xiàn)在我們就差一個(gè)token參數(shù)

翻了好一會(huì)才發(fā)現(xiàn)token原來(lái)是下面這個(gè)接口服務(wù)器響應(yīng)頭返回的Set-Cookie:

http://v.mp.uc.cn/video.html?uc_param_str=frdnsnpfvecpntnwprdssskt&from=media

以上有點(diǎn)亂，怎么獲取作者全部視頻就不說(shuō)了，我們來(lái)盤(pán)一下UC大魚(yú)獲取視頻鏈接的過(guò)程。

首先訪問(wèn)一個(gè)視頻鏈接：http://v.mp.uc.cn/video.html?uc_param_str=frdnsnpfvecpntnwprdssskt&from=media#!wm_cid=267399668026835968!!wm_aid=26fa9499c6dd453ebbfc4880b71aaa75!!wm_id=eafce118a8d04a7fb49edb26e67a16f4

然后取上面視頻鏈接的wm_aid參數(shù)拼接出下面鏈接：http://ff.dayu.com/contents/267399668026835968?biz_id=1002&_fetch_author=1&_fetch_incrs=1

訪問(wèn)后返回?cái)?shù)據(jù)如下：

然后我們從上面返回?cái)?shù)據(jù)分別取出：

ums_id":"97aff448e4250d3d"； 對(duì)應(yīng)視頻直鏈接口的ums_id參數(shù)

然后再訪問(wèn)下面鏈接：

取出服務(wù)器響應(yīng)頭返回的Set-Cookie:
