butubb 21ff01b894 fix(douyin): 缺 sec-ch-ua 请求头,网关回 200 + 空 body(不是「账号被封」)
先纠正一个我上一轮给错的结论:日志里的 `account blocked` **不是抖音说的**,是
MediaCrawler 自己编的:

    if response.text == "" or response.text == "blocked":
        raise Exception("account blocked")

真实情况只是**抖音返回了空 body**。我把它读成了「账号被风控」,还写进了运行历史和
给用户的结论里 —— 用户质疑「我网页版和手机版都能正常登录」,一查,他是对的。

实测定位(同一 URL、同一 cookie、同一参数):

  浏览器页面内 fetch : 200, 7077 字节  ✓
  httpx              : 200,    0 字节  ✗
    带 a_bogus       : 0 字节
    不带 a_bogus     : 0 字节
    四种 msToken 变体 : 全部 200 有数据(所以不是它)
  用浏览器那次的完整头重放 httpx : 200, 7077 字节 ✓

浏览器那次请求比爬虫多的,只有这三个头:

    sec-ch-ua: "Google Chrome";v="155", "Chromium";v="155", "Not(A:Brand";v=24
    sec-ch-ua-mobile: ?0
    sec-ch-ua-platform: "Linux"

爬虫的 UA 是从页面读的(声称是 Chrome 155)却不带 sec-ch-ua —— 「Chrome 的 UA +
没有 sec-ch-ua」是最典型的机器人特征。网关的回应方式是不报错、不给原因,回一个
200 + 空 body,HTTP 状态还写在成功那一栏。

修:media_platform/douyin/help.py 新增 client_hint_headers(),从
navigator.userAgentData 现算这三个头(现算而不是写死 —— 写死的版本号一旦和 UA 里的
对不上,就又是一个可疑特征);core.py 建客户端时带上。

诚实说明:我无法解释**为什么之前能跑**(run 34 还是成功的,40 分钟后同样的代码就
不行了)。最可能是字节那边收紧了这道校验,但我没有证据,别当结论。

测试 +8:还原出的头与真实浏览器抓到的值逐字一致;拿不到 userAgentData 时返回空而不
凭空编造(编一组和 UA 对不上的头比不带头更糟);mobile 标志;platform 缺失时仍发另两个。

📖 Project Introduction

A powerful multi-platform social media data collection tool that supports crawling public information from mainstream platforms including Xiaohongshu, Douyin, Kuaishou, Bilibili, Weibo, Tieba, Zhihu, and more.

🔧 Technical Principles

  • Core Technology: Based on Playwright browser automation framework for login and maintaining login state
  • No JS Reverse Engineering Required: Uses browser context environment with preserved login state to obtain signature parameters through JS expressions
  • Advantages: No need to reverse complex encryption algorithms, significantly lowering the technical barrier

✨ Features

Platform Keyword Search Specific Post ID Crawling Secondary Comments Specific Creator Homepage Login State Cache IP Proxy Pool Generate Comment Word Cloud

  • AI Agent based on comment analysis is under development 🚀🚀

Click to view: MediaCrawlerPro Project Homepage for more information

🚀 Quick Start

💡 Open source is not easy, if this project helps you, please give a ⭐ Star to support!

📋 Prerequisites

Before proceeding with the next steps, please ensure that uv is installed on your computer:

  • Installation Guide: uv Official Installation Guide
  • Verify Installation: Enter the command uv --version in the terminal. If the version number is displayed normally, the installation was successful
  • Recommendation Reason: uv is currently the most powerful Python package management tool, with fast speed and accurate dependency resolution

🟢 Node.js Installation

The project depends on Node.js, please download and install from the official website:

📦 Python Package Installation

# Enter project directory
cd MediaCrawler

# Use uv sync command to ensure consistency of python version and related dependency packages
uv sync

🌐 Browser Driver Installation

# Install browser driver
uv run playwright install

💡 Tip: MediaCrawler now supports using playwright to connect to your local Chrome browser, solving some issues caused by Webdriver.

Currently, xhs and dy are available using CDP mode to connect to local browsers. If needed, check the configuration items in config/base_config.py.

🚀 Run Crawler Program

# The project does not enable comment crawling mode by default. If you need comments, please modify the ENABLE_GET_COMMENTS variable in config/base_config.py
# Other supported options can also be viewed in config/base_config.py with Chinese comments

# Read keywords from configuration file to search related posts and crawl post information and comments
uv run main.py --platform xhs --lt qrcode --type search

# Read specified post ID list from configuration file to get information and comment information of specified posts
uv run main.py --platform xhs --lt qrcode --type detail

# Open corresponding APP to scan QR code for login

# For other platform crawler usage examples, execute the following command to view
uv run main.py --help

WebUI Support

🖥️ WebUI Visual Operation Interface

MediaCrawler provides a web-based visual operation interface, allowing you to easily use crawler features without command line.

For development, you need to start both the backend API service and the frontend Vite dev server:

# Terminal 1: start API server (default port 8080)
uv run uvicorn api.main:app --port 8080 --reload

# Terminal 2: start frontend dev server
cd webui
npm install
npm run dev        # starts on port 5173 by default and proxies /api to 8080

After successful startup, visit http://localhost:5173/ to open the WebUI interface.

On first launch, an environment check is performed (calls /api/env/check), so make sure the backend service is running. If the check fails, you can click "Skip Check" to bypass it temporarily.

Build for Production

If you want the API server to serve the WebUI static assets directly, build the frontend first:

cd webui
npm install
npm run build      # outputs to api/webui/

Then start only the API server:

uv run uvicorn api.main:app --port 8080 --reload

After successful startup, visit http://localhost:8080 to open the WebUI interface.

WebUI Features

  • Visualize crawler parameter configuration (platform, login method, crawling type, etc.)
  • Real-time view of crawler running status and logs
  • Data preview and export

Interface Preview

🔗 Using Python native venv environment management (Not recommended)

Create and activate Python virtual environment

If crawling Douyin and Zhihu, you need to install nodejs environment in advance, version greater than or equal to: 16

# Enter project root directory
cd MediaCrawler

# Create virtual environment
# My python version is: 3.9.6, the libraries in requirements.txt are based on this version
# If using other python versions, the libraries in requirements.txt may not be compatible, please resolve on your own
python -m venv venv

# macOS & Linux activate virtual environment
source venv/bin/activate

# Windows activate virtual environment
venv\Scripts\activate

Install dependency libraries

pip install -r requirements.txt

Install playwright browser driver

playwright install

Run crawler program (native environment)

# The project does not enable comment crawling mode by default. If you need comments, please modify the ENABLE_GET_COMMENTS variable in config/base_config.py
# Other supported options can also be viewed in config/base_config.py with Chinese comments

# Read keywords from configuration file to search related posts and crawl post information and comments
python main.py --platform xhs --lt qrcode --type search

# Read specified post ID list from configuration file to get information and comment information of specified posts
python main.py --platform xhs --lt qrcode --type detail

# Open corresponding APP to scan QR code for login

# For other platform crawler usage examples, execute the following command to view
python main.py --help
