Doubao Web Image Generator

This project/skill uses Playwright to automate browser control, directly utilizing the real environment of Doubao Web for image generation, perfectly bypassing the a_bogus signature risk control issue. (这个项目/技能通过 Playwright 自动化控制浏览器的方式，直接利用豆包 Web 端的真实环境进行图片生成，从而完美避开 a_bogus 签名风控问题。)

Features (功能)

Auto-save login status to ~/.doubao-web-session (自动保存登录状态在 ~/.doubao-web-session)
Send image generation Prompts in a real browser environment (在真实浏览器环境中发送生图 Prompt)
Intercept and parse SSE stream responses to get the watermark-free original image URL (拦截并解析 SSE 流式响应，获取无水印原图 URL)

How to Run (如何运行)

# Default headless mode (silent background run) and original image quality, saving to generated.png
# 默认使用无头模式 (后台静默运行) 和 获取原图画质，并默认保存为 generated.png
npx ts-node scripts/main.ts "A cyberpunk style cat (一只赛博朋克风格的猫咪)"

# Specify image save path (--output or --image)
# 指定图片保存路径 (--output 或 --image)
npx ts-node scripts/main.ts "A cyberpunk style cat" --output="./my_cyber_cat.png"

# Specify image quality (--quality=preview or --quality=original)
# preview fetches faster, original attempts to get high-res quality (default)
# 指定图片画质 (--quality=preview 或 --quality=original)
# preview 抓取速度更快，original 尝试获取大图画质 (默认)
npx ts-node scripts/main.ts "A cyberpunk style cat" --quality=preview --output="./preview_cat.png"

# For the first run or when login is required, you must use the --ui parameter to show the browser window
# 首次运行或需要登录时，必须使用 --ui 参数显示浏览器窗口
npx ts-node scripts/main.ts "Test" --ui

Technical Principle (技术原理)

Browser Hosting (浏览器托管): Use Playwright to launch a real Chromium browser, loading the user data directory. (利用 Playwright 启动一个真实的 Chromium 浏览器，加载用户数据目录。)
UI Automation (UI 自动化): Locate the input box, auto-fill Help me generate an image: {prompt} and simulate pressing Enter. (定位输入框，自动填入 帮我生成图片：{prompt} 并模拟回车。)
Network Interception (网络拦截): Listen to the POST request response of /samantha/chat/completion to get the complete SSE data stream. (监听 /samantha/chat/completion 的 POST 请求响应，获取完整的 SSE 数据流。)
Data Parsing (数据解析): Use regex to match the image_ori URL in the response stream. (使用正则匹配响应流中的 image_ori 的 URL。)

Directory Structure (目录结构)

scripts/doubao-webapi/client.ts - Core Playwright client logic (核心 Playwright 客户端逻辑)
scripts/main.ts - Command line entry file (命令行入口文件)
