2.调试页面

Network—>XHR
刷新，底部发现视频请求接口：

#6大参数
https://www.iesddddddouyin.com/web/api/v2/aweme/post/?
sec_uid=MS4wLjABAAAA0MTqN7ohUuTFM4Jga0qt-x__9pqLg_vY9quQPtGy_Y&

_signature=OqMnuxASZC3EKvfcJHZ0NTqjJ6&   (签名)
dytk=e70f8853eefed9d397090595598051cd

复制接口到浏览器

数据都在：aweme_list:[]中

视频链接：

"https://aweme.snssdk.com/aweme/v1/play/?video_id=v0200fb80000bptdot8ghl0vhjjpk06g&
line=0&ratio=540p&
watermark=1&
media_type=4&vr_type=0&
improve_bitrate=0&
logo_name=aweme&
is_support_h265=0&
source=PackSourceEnum_PUBLISH",复制链接到手机浏览器可以看到视频，pc网页上看不到

这个接口是有时间限制的

3.能获取到数据了，写请求
六大请求参数：

刷新了几次 ，发现只有签名在变

4._signature生成流程

index_10ae3b3.js

if ("music" === e) {a = "/web/api/v2/music/list/original/";var i = {user_id: params.user_id,sec_uid: params.sec_uid,count: params.count,cursor: params.max_cursor};t = i}t._signature = signature,t.dytk = dytk,

signature加密方法：

nonce = e.uid,signature = _bytedAcrawler.sign(nonce),_tea.default.setEventCommonParams({page_name: "reflow_user"}),

_bytedAcrawler

_bytedAcrawler = require("douyin_falcon:node_modules/byted-acrawler/dist/runtime")

douyin_falcon:node_modules/byted-acrawler/dist/runtime

third_a0e4a8f.js
/*!douyin_falcon:node_modules/byted-dp-event-collector/src/eventCollector.js*/加密方法：
__M.define("douyin_falcon:node_modules/byted-acrawler/dist/runtime",function(l,e){Function(function(l)

5.把signature的加密的js方法复用生成_signature

6.写请求
