# 智慧树 (zhihuishu.com) API 逆向分析
|
||||
|
||||
> 日期: 2026-06-23 | 全部接口已验证通过
|
||||
|
||||
---
|
||||
|
||||
## 一、概述
|
||||
|
||||
智慧树有两套 API 体系：
|
||||
|
||||
| 体系 | 域名 | 加密 | 课程类型 |
|
||||
|------|------|------|---------|
|
||||
| Zhidao | `studyservice-api` / `onlineservice-api` | AES-CBC (secretStr) | 共享学分课 |
|
||||
| Hike | `hikeservice` / `studyresources` / `hike-teaching` | 无加密 | 校内学分课 |
|
||||
|
||||
---
|
||||
|
||||
## 二、登录流程
|
||||
|
||||
### 4.1 密码登录（需要滑块验证码）
|
||||
|
||||
```
|
||||
Step 1: GET passport.zhihuishu.com/login → 获取 Session Cookie (JSESSIONID等)
|
||||
|
||||
Step 2: POST passport.zhihuishu.com/user/validateAccountAndPassword
|
||||
Body: secretStr=Base64(encodeURIComponent(JSON.stringify({
|
||||
account: "手机号",
|
||||
password: "密码",
|
||||
validate: "滑块验证码token"
|
||||
})))
|
||||
→ {status: 1, uuid: "...", pwd: "一次性密码"}
|
||||
|
||||
Step 3: POST appcomm-user.zhihuishu.com/.../checkNeedAuth
|
||||
Body: uuid=xxx
|
||||
→ {rt: {needAuth: 0}}
|
||||
|
||||
Step 4: GET passport.zhihuishu.com/login?pwd={pwd}&service={service}
|
||||
→ 302重定向链 → 设置 CASLOGC Cookie
|
||||
注意: 必须用 requests 库跟随重定向，urllib 不会自动跨域传 Cookie
|
||||
|
||||
加密方式: btoa(encodeURIComponent(JSON)) — 就是 Base64 + URL编码
|
||||
(不是 AES！这是登录专用加密)
|
||||
```
|
||||
|
||||
### 4.2 滑块验证码
|
||||
|
||||
网易易盾，captchaId: `75f9f716460a422f89a628f50fd8cc2b`
|
||||
|
||||
```html
|
||||
<script src="https://cstaticdun.126.net/load.min.js"></script>
|
||||
<script>
|
||||
initNECaptcha({
|
||||
element: '#captcha',
|
||||
captchaId: '75f9f716460a422f89a628f50fd8cc2b',
|
||||
mode: 'popup',
|
||||
onVerify: function(err, data) {
|
||||
// data.validate 就是需要的 token
|
||||
}
|
||||
}, onload, onerror);
|
||||
</script>
|
||||
```
|
||||
|
||||

|
||||
|
||||
## 三、Zhidao API（共享学分课）
|
||||
|
||||
### 5.1 AES 加密

||||
"video": b"azp53h0kft7qi78q", # 视频/学习/进度
|
||||
"qa": b"kcGOlISPkYKRksSK", # 弹题
|
||||
}
|
||||
IV = b"1g3qqdh4jvbskb9x"
|
||||
|
||||
def aes_encrypt(data_str, key=KEY_MAP["video"]):
|
||||
pad_len = 16 - len(data_str) % 16
|
||||
padded = data_str + chr(pad_len) * pad_len
|
||||
cipher = AES.new(key, AES.MODE_CBC, IV)
|
||||
return base64.b64encode(cipher.encrypt(padded.encode())).decode()
|
||||
```
|
||||
|
||||
**请求格式：**
|
||||
```
|
||||

|
||||
Body: secretStr={AES密文}&dateFormate={毫秒时间戳}
|
||||
```
|
||||

|
||||
|
||||
### 5.2 课程列表

|
||||
加密密钥: VIDEO_KEY
|
||||
加密前:
|
||||
{
|
||||

|
||||
{
|
||||
"code": 0,
|
||||
"data": {
|
||||
"lv": {
|
||||
"4001": { "watchState": 1, "studyTotalTime": 600 }
|
||||
},
|
||||
"lesson": {
|
||||
"1001297571": { "watchState": 1, "studyTotalTime": 600 }
|
||||
}
|
||||
}
|
||||
}
|
||||
watchState: 0=未看完, 1=已看完
|
||||
studyTotalTime: 已学习秒数
|
||||
```
|
||||
|
||||
### 5.7 提交学习进度
|
||||
|
||||
```
|
||||
Step 1 (prelearningNote):
|
||||
POST studyservice-api.zhihuishu.com/gateway/t/v1/learning/prelearningNote
|
||||
加密密钥: VIDEO_KEY
|
||||
加密前: {"ccCourseId":...,"chapterId":...,"isApply":1,"lessonId":...,
|
||||
"lessonVideoId":...,"recruitId":...,"videoId":...,"dateFormate":时间戳}
|
||||
返回: data.studiedLessonDto.id → Base64编码得到 learningTokenId
|
||||
|
||||
Step 2 (saveDatabaseIntervalTimeV2):
|
||||
POST studyservice-api.zhihuishu.com/gateway/t/v1/learning/saveDatabaseIntervalTimeV2
|
||||
加密密钥: VIDEO_KEY
|
||||
加密前: {
|
||||
"ewssw": "0,1,2", // watchPoint
|
||||
"sdsew": getEv([...]), // EV混淆的参数
|
||||
"zwsds": learningTokenId, // Base64编码的token
|
||||
"courseId": ...,
|
||||
"dateFormate": 时间戳
|
||||
}
|
||||
```
|
||||
|
||||
### 5.8 EV 混淆算法
|
||||
|
||||
```python
|
||||
def getEv(data_list, key="zzpttjd"):
|
||||
"""XOR 混淆"""
|
||||
data = ';'.join(map(str, data_list))
|
||||
key_cycle = (ord(c) for _ in iter(int,1) for c in key)
|
||||
ev = ''
|
||||
for c in data:
|
||||
tmp = hex(ord(c) ^ next(key_cycle)).replace('0x', '')
|
||||
if len(tmp) < 2: tmp = '0' + tmp
|
||||
ev += tmp[-4:]
|
||||
return ev
|
||||
|
||||
# saveDatabaseIntervalTimeV2 的 raw_ev 参数:
|
||||
raw_ev = [
|
||||
recruitId, lessonId, smallLessonId, videoId, chapterId,
|
||||
'0', # studyStatus
|
||||
played_time - last_submit, # 本次播放时长
|
||||
played_time, # 累计播放时长
|
||||
HMS(played_time), # HH:MM:SS 格式
|
||||
uuid + "zhs" # UUID后缀
|
||||
]
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 四、Hike API（校内学分课）
|
||||
|
||||
无需 AES 加密，直接 GET 请求，带 Cookie 即可。
|
||||
|
||||
### 6.1 课程列表
|
||||
|
||||
```
|
||||
GET hikeservice.zhihuishu.com/student/course/aided/getMyCourseList?uuid={uuid}&data={UTC时间}
|
||||
返回: result.startInngcourseList (注意拼写)
|
||||
```
|
||||
|
||||
### 6.2 章节/资源树
|
||||
|
||||
```
|
||||
GET studyresources.zhihuishu.com/studyResources/stuResouce/queryResourceMenuTree?courseId={id}
|
||||
返回: rt 数组，childList 非空=目录，childList=null=文件，dataType=3=视频
|
||||
```
|
||||
|
||||
### 6.3 视频信息
|
||||
|
||||
```
|
||||
GET studyresources.zhihuishu.com/studyResources/stuResouce/stuViewFile?courseId={id}&fileId={id}
|
||||
返回: dataId (视频流ID), totalTime, studyTime
|
||||
```
|
||||
|
||||
### 6.4 提交学习记录
|
||||
|
||||
```
|
||||
GET hike-teaching.zhihuishu.com/stuStudy/saveStuStudyRecord?uuid=...&courseId=...&fileId=...
|
||||
&studyTotalTime=...&startWatchTime=...&endWatchTime=...&startDate=...&endDate=...
|
||||
&signature=MD5(SALT + uuid + courseId + fileId + studyTotalTime + startDate + endDate + endWatchTime + startWatchTime + uuid)
|
||||
|
||||
SALT = "o6xpt3b#Qy$Z"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 五、Cookie 体系
|
||||
|
||||
登录后获取的关键 Cookie：
|
||||
|
||||
| Cookie | 域名 | 说明 |
|
||||
|--------|------|------|
|
||||
| CASLOGC | passport.zhihuishu.com | URL编码JSON，含uuid/realName/userId |
|
||||
| JSESSIONID | passport.zhihuishu.com | Session ID |
|
||||
| SERVERID | 各子域名 | 服务器路由 |
|
||||
| SESSION | onlineservice-api / studyservice-api | API会话 (通过CAS重定向获取) |
|
||||
|
||||
⚠️ 登录时必须跟随完整 CAS 重定向链，否则缺少 `onlineservice-api` 的 SESSION Cookie 导致 API 返回 401。
|
||||
|
||||
---
|
||||
|
||||
## 六、关键注意事项
|
||||
|
||||
1. **AES JSON 格式**: `json.dumps(data, separators=(',', ':'))` — 紧凑格式，无空格
|
||||
2. **dateFormate 双写**: 加密 JSON 内和表单字段都要有，且值相同
|
||||
3. **lessonVideoIds 不能含 0**: 单视频课时 smallLessonId=0，此时传空数组 `[]`
|
||||
4. **CAS 重定向**: 必须用 requests.Session() 自动跟随，urllib 不会跨域传 Cookie
|
||||
5. **latin-1 编码**: Cookie 值保持 URL 编码状态（纯 ASCII），不要解码成中文
|
||||
6. **Encrypt 已变更**: 登录接口用 `btoa(encodeURIComponent(JSON))`，不是 AES
