闲来无事系列-雨课堂抓包发包玩法（娱乐向）

今天开心的玩游戏，突然发来通知，增加了一门课程，打开一看，噢，原来是雨课堂

其实，本来通过多开挂机的方式，完成了大部分的课程了，但是，还是想探究一下，这个原理，于是乎，留了几节课，用来实验。

为什么要这么玩呢，因为很久之前（非本次），某网站的长达几个小时的视频，通过python伪造请求，可以做到10s看完，非常有意思

这个网站的视频逻辑是不断发包请求

但是每个包的请求的视频点，不得超过太长时间，否则失效。以下为破解代码

import requests
import random
import time
import math
courseId = "****"
videoId = "****"
longtime = 1000
viewUUID = "****"
cs = {
        "_fecdn_":"1",
        "gr_user_id":"****",
        "****_gr_session_id":"****",
        "grwng_uid":"****",
        "****":"true",
        "UniqueKey":"****",
        "lebanban_auth":"****",
        "fb_auth":"****",
        "****_gr_last_sent_sid_with_cs1":"****",
        "****_gr_last_sent_cs1":"****",
        "****_gr_cs1":"****",
        "JSESSIONID":"****"
    }
hs = {
        "Host":"www.****.com",
        "Connection":"keep-alive",
        "Accept":"application/json, text/javascript, */*; q=0.01",
        "X-Requested-With":"XMLHttpRequest",
        "User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4139.0 Safari/537.36 Edg/84.0.516.1",
        "Content-Type":"application/x-www-form-urlencoded",
        "Origin":"https://www.****.com",
        "Sec-Fetch-Site":"same-origin",
        "Sec-Fetch-Mode":"cors",
        "Sec-Fetch-Dest":"empty",
        "Referer":"https://www.****.com/course/introduction/"+courseId+".shtml",
        "Accept-Encoding":"gzip, deflate, br",
        "Accept-Language":"zh-CN,zh;q=0.9,en;q=0.8,en-GB;q=0.7,en-US;q=0.6",
    }

monitor = {
    "courseId":courseId,
    "videoId" : videoId,
    "resourceType":"0",
    "currentSec":0,
    "viewUUID":viewUUID,
    "bufferTime":0
    }

end = math.floor(longtime * 60)
for c in range(1,end+5,5):
    tranceId = (str(time.time()*1000)[:13]+str(random.randint(10,99)))[-11:];
    monitor["currentSec"] = c
    monitor["bufferTime"] = random.randint(1,99)
    url = "https://www.****.com/learn/common/playstatistics.json?traceId=" + tranceId
    rsp = requests.post(url,headers=hs,cookies=cs,params=monitor)
    print(rsp.text)

回归正题，一起来了解一下雨课堂的情况。

反手就是打开 fiddler，点开课程抓包看看情况。

（远不止这些包）

每次请求，和得到的回包，都用notepad++记录一下，以便于之后，通过请求获取具体的课堂信息等

除了分析了300多行，想了解一下，每个包的目的等。

首先，我先教大家使用notepad++里面，好用的js和json的格式自动排版工具

JSTool和JSON Viewer。。。。。JSON Viewer可以一键将json格式化

至于JSTool，好羞愧啊，刚开始，有些参数没有弄明白，我直接去后台扒JS看了，emmmmmm，乱七八糟的（混淆了），放弃了。

接下来，我将具体说明每个请求和每个包的作用（*为手动马赛克）

先放上感觉没有用的包。

#获取学校信息（暂时没啥作用，因为返回来的包，没什么有价值的东西）
GET https://****.yuketang.cn/edu_admin/get_custom_university_info/?current=1 

GET https://****.yuketang.cn/edu_admin/get_custom_university_info/?host_name=****.yuketang.cn&no_loading=true&term=latest&uv_id=0000

#导出列表（暂时没用）
GET https://****.yuketang.cn/edu_admin/display_data_dashboard/export_list/?no_loading=true&page_size=10&page=1
#回包
{"msg": "", "data": {"exporting_count": 0, "page_size": 0, "task_list": []}, "success": true}

回包含有我需要的参数的包。

# 获取课堂信息
GET https://****.yuketang.cn/mooc-api/v1/lms/learn/classroom_info/?classroom_id=****&sign=****&term=latest&uv_id=****
# 回包
{
	"msg": "",
	"data": {
		"notice": false,
		"end": 1611000000000.0, #课堂的结束时间（已随机修改）
		"name": "***",
		"start": 1604000000000.0,#课堂的开始时间（已随机修改）
		"course_name": "***",
		"is_class_end": false,
		"teacher": {
			"picture": "***",
			"name": "***"
		}
	},
	"success": true
}

# 获取该课堂的章节
GET https://****.yuketang.cn/mooc-api/v1/lms/learn/course/chapter?cid=****&sign=****&term=latest&uv_id=**** HTTP/1.1

# 部分回包
"section_leaf_list": [{
				"order": 0,
				"leaf_list": [{
					"name": "Video",
					"is_locked": false,
					"start_time": ****, # 开始时间
					"chapter_id": ****, # 章节id
					"section_id": ****, # 部分id（参数可能有用）
					"leaf_type": 0,
					"id": ****, #（参数可能有用）
					"is_show": true,
					"end_time": 0,

					"leafinfo_id": **** #叶子id （参数可能有用）
				}],
				"chapter_id": ****,
				"id": ****,
				"name": "章节名称"
			}

下面这个包，几乎包含了所有的信息，大概如下

# 通过课堂名，章节名，还有sign还有university_id，获取信息
GET https://****.yuketang.cn/mooc-api/v1/lms/learn/leaf_info/****/****/?sign=****&term=latest&uv_id=****

这里自动跳过了暂时无用包

# 获取视频的观看进度

GET https://****.yuketang.cn/video-log/get_video_watch_progress/?cid=****&user_id=****&classroom_id=****&video_type=video&vtype=rate&video_id=****&snapshot=1&term=latest&uv_id=****

# 
{
	"****": {
		"last_point": ****, # 最近的一次
		"completed": 0,
		"first_point": ****,
		"video_length": ****,# 视频长度
		"rate": ****
	},
	"message": null,
	"code": 0,
	"data": {
		"****": {
			"last_point": ****,
			"completed": 0,
			"first_point": ****,
			"video_length": ****,
			"rate": ****
		}
	}
}

这里提一下，可以利用爬虫来获取讨论区的内容并筛选

讨论区也是学生的作业，每个人必须要评论，可以通过爬虫获取，分析，重组评论，直接发包评论（有想法，没有去实现）

# 获取评论区

GET https://****.yuketang.cn/v/discussion/v2/comment/list/****/?_date=****&term=latest&offset=0&limit=10&web=web 

# 回包

{
	"msg": "",
	"data": {

			"previous": null,
			"results": [],
			"next": null

					],
					"commented": 0,
					"content": {

						"upload_images": []

					"user_info": {

				},

视频都在这个包，可以通过视频源地址下载（我不清楚网站有没有提供下载地址，没了解）

# 获取某视频的URL
https://****.yuketang.cn/api/open/audiovideo/playurl?_date=****&term=latest&video_id=****&provider=cc&file_type=1&is_single=0 


# 回包
！！！！大家看到wsSecret了吗，从这里可以获取，其他地方好像也可以，我记不清了
{
	"msg": "",

				"quality20": [
					"https://ws.cdn.xuetangx.com/****-20.mp4?wsSecret=****&wsTime=****"

	},

}

#大家都知道， 字幕是另外加的，通过这个请求，可获得所有字幕

}

还有许多包，这里就不赘述了。

既然大概的发包情况都了解了，那么，开始写代码吧，先把全局变量安排好

import requests
import random
import time
import math
import json

接下来，构造请求头，cookies等json包

接下来，通过GET https://0.yuketang.cn/mooc-api/v1/lms/learn/leaf_info/这个

def getInfor():# 获取信息
    url = "https://0.yuketang.cn/mooc-api/v1/lms/learn/leaf_info/" + classroom_id + "/" + video_id + "/"
    rsp = requests.get(url,headers = headers, cookies = cookies, params = leaf_info)
    jRes = json.loads(rsp.text)
    course_id = jRes["data"]["course_id"]
    user_id = jRes["data"]["user_id"]
    sku_id = jRes["data"]["sku_id"]
    cc_id = jRes["data"]["content_info"]["media"]["ccid"]
    print("详细信息查询" + str(course_id) + " : " + str(user_id) + " : " + str(sku_id) + " : " + str(cc_id))

通过模拟

def getClass():
    global heart_beat_time
    for i in range(10):
        url = "https://0.yuketang.cn/video-log/get_video_watch_progress/"

        jRes = json.loads(rsp.text)
        last_point = jRes[video_id]["last_point"]
        first_point = jRes[video_id]["first_point"]
        video_length = jRes[video_id]["video_length"]
        print("第 " + str(heart_beat_time) + " 次视频进度查询" + str(last_point) + " : " + str(first_point) + " : " + str(video_length))

        nowDate = str(int(time.time() * 1000))     # 跳动时间

        heart_beat["heart_data"][0]["ts"] = nowDate

        print("第 " + str(heart_beat_time) + " 次心脏:" + rsp.text)
        heart_beat_time += 1
        sleep(000000000000000000000000000000)

但是每个包的请求的视频点，不得超过太长时间，否则失效。以下为破解代码

回归正题，一起来了解一下雨课堂的情况。

接下来，我将具体说明每个请求和每个包的作用（*为手动马赛克）

这里自动跳过了暂时无用包

这里提一下，可以利用爬虫来获取讨论区的内容并筛选

还有许多包，这里就不赘述了。

接下来，通过GET https://0.yuketang.cn/mooc-api/v1/lms/learn/leaf_info/这个

cookies等怎么获取呢

如果大家想了解更多这种原理等，可以看看之前的cf活动领取器，通过抓包发包进行操作，超级方便。

还记得逆战当初出活动（貌似是爱丽丝）翻车了，通过穷举，获取红包，白嫖了好几百块的东西，233333333
