全局	`output_gzip`, `rules_dirs`, `rules_auto_update`, `trace_rules`, `clear_context_cookies`, `log_level`, `rules_dirs_enabled`	GlobalSettings, see below

代理

代理模块由 7 文件组成的三层架构：

[
    "http://user:pass@proxy1.example.com:8080",
    "http://proxy2.example.com:3128",
    "socks5://proxy3.example.com:1080"
]

astrocrawl https://example.com -d 3 -p proxies.json

代理模式：direct_only（默认，直连不代理）| prefer_proxy（优先代理，不可用时退直连）| prefer_direct（优先直连，失败时切代理）| proxy_only（强制代理，无代理时启动即报错）

核心机制：

ProxyManager（SWRR 负载均衡）：Smooth Weighted Round-Robin 分配代理到浏览器上下文槽位
ProxyHealthTracker（3 级断路器）：CLOSED → OPEN（3 次连续失败熔断，30s 冷却）→ HALF_OPEN（15s 考察窗口）→ CLOSED；再次熔断冷却 ×1.5（最大 120s）
TCP 主动探测：后台 asyncio 循环周期性 TCP connect 探测 OPEN 状态代理，自动恢复
DomainPathMemory（双缓存）：按域名记忆代理/直连决策，Phase 0 快捷路径，TTL 3600s
ProxySession（组合根 + DI）：异步上下文管理器，组合 ProxyManager + ProxyHealthTracker + 后台探活循环，通过 DI 注入 BrowserPool/aiohttp/AI/Preview 等消费者
ProxyFailureClassifier（SSOT）：将 Playwright/网络错误映射为 4 种重试策略 — ROTATE_PROXY / REPLACE_CONTEXT / TRANSIENT / FATAL
Consumer Routing：PROXY_CONSUMERS 注册表（preview/ai/source），GUI _RouteSettingsPage 为每消费者配置 Profile | Node 路由
ProxyProfile（配置档案）：4 字段 frozen dataclass + UUID 身份，完整 CRUD 内置于 Preferences，GUI 表格管理 + 编辑器
缺代理启动门控：proxy_only/prefer_proxy/prefer_direct 无代理时直接 ConfigError，防止静默降级

输出格式

JSONL（内容输出）

{"url": "https://example.com/page1", "depth": 1, "text": "页面文本...", "title": "Example Page", "timestamp": 1714521600.123}

结构化提取模式下，额外包含 extraction_type 和 fields：

{"url": "https://example.com/product/1", "depth": 2, "text": "", "title": "商品页标题", "timestamp": 1714521600.456, "extraction_type": "example_product", "fields": {"product_title": "商品名", "price": "99.00"}}

所有页面默认包含 schema_org 字段（JSON-LD / Microdata 自动解析）。仅写入 ok 和 truncated 状态的页面。可选 GZip 压缩（默认开启）。配套生成 <output>.report.json 统计报告。

统计报告（摘要）

{
    "outcome_summary": {"ok": 420, "duplicate": 30, "fetch_error": 8},
    "domain_stats": [{"domain": "example.com", "ok": 420, "avg_ms": 2340.5}],
    "depth_layers": {"0": {"processed": 1, "planned": 1}},
    "duration_seconds": 930.5
}

崩溃恢复

使用相同的输出路径再次启动，自动续爬。

astrocrawl https://example.com -d 3 -o data.jsonl
# 中断后…
astrocrawl https://example.com -d 3 -o data.jsonl   # 自动续爬

恢复逻辑：in_flight URL 自动重新入队、进度层从持久化 meta 表恢复、深度变化时边界链接自动展开/暂存、自愈检测从链接图找回丢失子链接、DB 可重试 URL 回收。

提取规则引擎

声明式 CSS 选择器结构化提取系统对标 Zyte/Hext 的页面类型模型：

规则结构：ExtractionRule（名称 + 域名 + url_pattern + fields[选择器/transform] + test_urls）
匹配流程：RuleSnapshot 全量快照 → by_domain 索引 → MatchScope 4 级精确度排序 → RuleMatchCache 域名级缓存
提取流程：CSS 选择器（text/attr/html，支持 multiple 数组 + fallback 链） → RuleTransform 5 变换（strip/strip_currency/regex/replace/join） → 结构化输出
规则源：3 层（用户 > 远程 > pip预置 > default），远程源 HTTPS-only + SHA256 校验
HTML 预处理：3 级清洗（OFF/CANONICAL/STRICT），AI 规则生成前自动执行
安全设计：re2 硬依赖（线性时间，ReDoS 免疫）、3 层验证模型（L2 导入预览 → L1 持久化门 → L0 加载兜底）、DNS rebinding 硬阻断、Unicode 控制字符清洗

AI 多 Provider 架构

领域无关的通用 AI 底座，astrocrawl/ai/ 16 文件 2,638 行，零 Provider SDK 导入：

组件	说明
AIClient 门面	统一 API — `chat()`/`achat()`/`chat_stream()`/`achat_stream()`/`embed()`，异步上下文管理器
Provider 注册表	`importlib.metadata` entry point 自动发现，工厂模式创建，3 个内置 Provider 包
RateLimiter	TokenBucket + BoundedSemaphore，sync/async 共享预算
UsageTracker	会话级 TokenUsage 累加器
AIHook 可观测性	OTel 对齐 — on_request/on_response/on_error/on_retry，4 生命周期钩子
StreamEvent	Vercel AI SDK 对齐 5 事件判别联合 — StreamText/StreamToolCallStart/StreamToolCallDelta/StreamToolCall/StreamFinish
Tool Calling	归一化 `ToolCall`，`arguments` 已解析为 dict
Embeddings	ISP 分离 `_SupportsEmbedding` 协议，OpenAI/Google Provider 支持
AIProfile	10 字段 frozen dataclass，多 Profile CRUD，持久化在 Preferences 中
C-mode 选择	每 AI 消费者模块独立选择并记忆 Profile，对标 Cursor/Continue.dev
动态模型列表	约定发现 `list_models()`，GUI 异步拉取 + Refresh 按钮
异常体系	9 个 Provider 无关异常类 — AIAuthError/AIRateLimitError/AITimeoutError 等

架构

入口层   main.py → CLI (cli/main.py) / GUI (gui/*.py)
引擎层   AsyncCrawler — Processor Chain (8 processors) + WorkerSupervisor + LivenessTracker + UrlGate
插件层   plugin/ — discover → register → lifecycle → dispatch → security (4-layer defense + sandbox + signing)
规则层   rules/ (RuleSnapshot → match → CSS extract → transform) + ai/ (多Provider AI底座)
设施层   browser/ (BrowserPool Actor + ContextPool strategy + SlotPool mechanism + PagePool)
         network/ (aiohttp_retry_fetch + RobotsCache data/policy + RateLimiter×2 + SitemapDiscovery)
         storage/ (CrawlState SQLite WAL + AsyncJsonlWriter JSONL+GZip)
         proxy/   (ProxyManager SWRR + ProxyHealthTracker 3-tier CB + ProxySession DI + TCP probe)
工具层   utils/ (URL 规范化/脱敏 + HTML 解析/RobustHash + Logging logfmt + Preferences CRUD + 原子写入)
配置层   config.py (GlobalSettings 7 + CrawlerConfig 50 frozen dataclasses) + _constants.py + _types.py
         + _path_strategy.py + _retry_strategy.py + _startup.py + _packaged.py + _version.py
         + health.py + health_monitor.py (A/B/C 调度) + resilience.py (Fuse) + diagnostics.py (三重诊断)

核心原则：引擎层不依赖任何 CLI 或 GUI 代码，通过可选的 CrawlerSignals Qt 信号对象与 GUI 通信。Worker 通过 FetchRequest 消息模式与 BrowserPool Actor 交互，不直接接触 Playwright。关键设计范式：Mechanism/Strategy 分离、Data/Policy 分离、lock-free snapshot 读模式、BEGIN IMMEDIATE 事务、不可变配置、ISP 窄接口（PEP 544 Protocol）、Provider-agnostic 零 SDK 导入、插件纵深防御（4 层安全：AST 扫描→PEP 578→seccomp-bpf→Landlock FS ACL）。

English Documentation

AstroCrawl is a full-featured async web crawler built on Playwright headless Chromium — 29,477 lines of Python across 113 source files, 3 built-in AI providers, 103 test files with 0 tests. It supports JavaScript rendering, robots.txt compliance (RFC 9309), automatic sitemap discovery, proxy rotation, content deduplication, crash recovery, a declarative CSS-selector extraction rules engine, a universal plugin system, and a multi-provider AI infrastructure. Available as both a PySide6 GUI desktop app and a feature-complete CLI tool.

Core Capabilities

Capability	Description
JavaScript Rendering	Playwright headless Chromium with full JS execution and CDP health checks
robots.txt Compliance	RFC 9309 — data/policy separated, robots.txt always fetched, Disallow enforcement togglable, Crawl-Delay independently controlled
Sitemap Discovery	Auto-discovery from robots.txt / default paths, recursive Sitemap Index parsing, UrlGate unified admission
Structured Extraction	Declarative CSS-selector rule engine — MatchScope 4-tier precision, field-level extraction + 5-transform pipeline, 3-tier rule sources (user/remote/pip)
Schema.org Extraction	Zero-cost auto-extraction of JSON-LD and Microdata structured data, executed for all pages
AI-Assisted Rule Generation	Dual-path: external AI ChatML paste+import / GUI one-click API call, zero-shot prompt, shared 3-tier HTML preprocessing
AI Multi-Provider Foundation	3 providers (OpenAI/Anthropic/Google), multi-profile management, C-mode context selection, streaming/tool calling/embeddings
Proxy Rotation	4 proxy modes + 3-tier circuit breaker + active TCP probing + DomainPathMemory dual-cache + ProxyProfile management

Environment Variables

Key Config Fields

CrawlerConfig has 50 fields total — an immutable frozen dataclass (frozen=True), modified via the replace() method. Cross-session global settings are managed independently by GlobalSettings (7 fields), persisted via Preferences and explicitly injected into the engine.

Category	Key Fields	Defaults
Browser	`page_timeout`, `viewport_width/height`, `user_agent`, `page_pool_size_per_context`	20000ms, 1280×720, auto, 2
Concurrency	`concurrency`, `domain_max_concurrency`, `domain_min/max_delay`, `max_retries`	8, 3, 1.0–5.0s, 3

Proxy

Proxy module consists of 7 files in a three-tier architecture:

[
    "http://user:pass@proxy1.example.com:8080",
    "http://proxy2.example.com:3128",
    "socks5://proxy3.example.com:1080"
]

astrocrawl https://example.com -d 3 -p proxies.json

Proxy Modes: direct_only (default, no proxy) | prefer_proxy (proxy preferred, fallback to direct) | prefer_direct (direct preferred, fallback to proxy) | proxy_only (proxy required, startup error if none configured)

Core Mechanisms:

ProxyManager (SWRR load balancing): Smooth Weighted Round-Robin assigns proxies to browser context slots
ProxyHealthTracker (3-tier circuit breaker): CLOSED → OPEN (3 consecutive failures, 30s cooldown) → HALF_OPEN (15s probe window) → CLOSED; cooldown ×1.5 on re-trip (max 120s)
Active TCP Probing: Background asyncio loop periodically TCP-connects to OPEN proxies for auto-recovery
DomainPathMemory (dual-cache): Per-domain proxy/direct decision memory, Phase 0 fast path, TTL 3600s
ProxySession (composite root + DI): Async context manager composing ProxyManager + ProxyHealthTracker + background probe loop, injected into BrowserPool/aiohttp/AI/Preview consumers
ProxyFailureClassifier (SSOT): Maps Playwright/network errors to 4 retry strategies — ROTATE_PROXY / REPLACE_CONTEXT / TRANSIENT / FATAL
Consumer Routing: PROXY_CONSUMERS registry (preview/ai/source), GUI _RouteSettingsPage per-consumer Profile | Node routing
ProxyProfile: 4-field frozen dataclass + UUID identity, full CRUD in Preferences, GUI table management + editor
Missing-Proxy Startup Guard: proxy_only/prefer_proxy/prefer_direct raise ConfigError when no proxies configured, preventing silent degradation

Output Format

JSONL (Content Output)

{"url": "https://example.com/page1", "depth": 1, "text": "Page text...", "title": "Example Page", "timestamp": 1714521600.123}

Under structured extraction mode, extraction_type and fields are added:

{"url": "https://example.com/product/1", "depth": 2, "text": "", "title": "Product Page Title", "timestamp": 1714521600.456, "extraction_type": "example_product", "fields": {"product_title": "Product Name", "price": "99.00"}}

All pages include a schema_org field by default (JSON-LD / Microdata auto-extraction). Only pages with ok and truncated status are written. Optional GZip compression (on by default). A <output>.report.json stats report is generated alongside.

Stats Report (Summary)

{
    "outcome_summary": {"ok": 420, "duplicate": 30, "fetch_error": 8},
    "domain_stats": [{"domain": "example.com", "ok": 420, "avg_ms": 2340.5}],
    "depth_layers": {"0": {"processed": 1, "planned": 1}},
    "duration_seconds": 930.5
}

Crash Recovery

Restart with the same output path to auto-resume.

astrocrawl https://example.com -d 3 -o data.jsonl
# After interruption…
astrocrawl https://example.com -d 3 -o data.jsonl   # Auto-resume

Recovery logic: in_flight URLs auto re-enqueued, depth layers restored from persistent meta table, boundary links auto-expand/stash on depth change, self-healing detection recovers lost child links from the link graph, DB retryable URL recovery via peek_retryable.

Extraction Rules Engine

Declarative CSS-selector structured extraction system modeled on Zyte/Hext page-type model:

Rule Structure: ExtractionRule (name + domains + url_pattern + fields[selector/transform] + test_urls)
Match Flow: RuleSnapshot full snapshot → by_domain index → MatchScope 4-tier precision ranking → RuleMatchCache domain-level cache
Extract Flow: CSS selector (text/attr/html, supporting multiple arrays + fallback chains) → RuleTransform 5 transforms (strip/strip_currency/regex/replace/join) → structured output
Rule Sources: 3 tiers (user > remote > pip > default), remote sources HTTPS-only + SHA256 verification
HTML Preprocessing: 3-tier cleaning (OFF/CANONICAL/STRICT), auto-executed before AI rule generation
Security by Design: re2 hard dependency (linear-time, ReDoS-immune), 3-tier validation model (L2 import preview → L1 persistence gate → L0 load-time guard), DNS rebinding hard block, Unicode control char sanitization

AI Multi-Provider Architecture

Domain-agnostic, general-purpose AI foundation — astrocrawl/ai/ 16 files, 2,638 lines, zero Provider SDK imports:

Component	Description
AIClient Facade	Unified API — `chat()`/`achat()`/`chat_stream()`/`achat_stream()`/`embed()`, async context manager
Provider Registry	`importlib.metadata` entry point auto-discovery, factory pattern, 3 built-in provider packages
RateLimiter	TokenBucket + BoundedSemaphore, sync/async shared budget
UsageTracker	Session-level TokenUsage accumulator
AIHook Observability	OTel-aligned — on_request/on_response/on_error/on_retry, 4 lifecycle hooks
StreamEvent	Vercel AI SDK-aligned 5-event discriminated union — StreamText/StreamToolCallStart/StreamToolCallDelta/StreamToolCall/StreamFinish
Tool Calling	Normalized `ToolCall` with parsed `arguments: dict`
Embeddings	ISP-separated `_SupportsEmbedding` protocol, supported by OpenAI/Google providers
AIProfile	10-field frozen dataclass, multi-profile CRUD, persisted in Preferences
C-mode Selection	Per-module independent profile selection with memory, modeled on Cursor/Continue.dev
Dynamic Model List	Convention-based `list_models()` discovery, GUI async fetch with Refresh button
Exception Hierarchy	9 provider-agnostic exception classes — AIAuthError/AIRateLimitError/AITimeoutError/etc.

Architecture

Entry Layer   main.py → CLI (cli/main.py) / GUI (gui/*.py)
Engine Layer  AsyncCrawler — Processor Chain (8 processors) + WorkerSupervisor + LivenessTracker + UrlGate
Plugin Layer  plugin/ — discover → register → lifecycle → dispatch → security (4-layer defense + sandbox + signing)
Rules Layer   rules/ (RuleSnapshot → match → CSS extract → transform) + ai/ (Multi-provider AI foundation)
Infra Layer   browser/ (BrowserPool Actor + ContextPool strategy + SlotPool mechanism + PagePool)
              network/ (aiohttp_retry_fetch + RobotsCache data/policy + RateLimiter×2 + SitemapDiscovery)
              storage/ (CrawlState SQLite WAL + AsyncJsonlWriter JSONL+GZip)
              proxy/   (ProxyManager SWRR + ProxyHealthTracker 3-tier CB + ProxySession DI + TCP probe)
Utils Layer   utils/ (URL normalize/redact + HTML parse/RobustHash + Logging logfmt + Preferences CRUD + atomic writes)
Config Layer  config.py (GlobalSettings 7 + CrawlerConfig 50 frozen dataclasses) + _constants.py + _types.py
              + _path_strategy.py + _retry_strategy.py + _startup.py + _packaged.py + _version.py
              + health.py + health_monitor.py (A/B/C scheduling) + resilience.py (Fuse) + diagnostics.py (triple diagnostics)

Core principle: the engine layer has zero dependency on CLI or GUI code, communicating with the GUI via an optional CrawlerSignals Qt signals object. Workers interact with BrowserPool through asynchronous FetchRequest messages and never touch Playwright directly. Key design paradigms: Mechanism/Strategy separation, Data/Policy separation, lock-free snapshot reads, BEGIN IMMEDIATE transactions, immutable configuration, ISP narrow interfaces (PEP 544 Protocol), provider-agnostic zero SDK imports, plugin defense-in-depth (4-layer security: AST scan → PEP 578 → seccomp-bpf → Landlock FS ACL).

Tech Stack

Layer	Technology
Language	Python 3.12+
Browser Automation	Playwright (Chromium headless)
HTTP Client	aiohttp + TCPConnector
Database	aiosqlite (WAL mode)
HTML Parsing	BeautifulSoup4 + lxml
Regex Engine	google-re2 (linear-time, ReDoS-immune, hard runtime dependency)
AI Client	openai / anthropic / google-genai (multi-provider, entry point auto-discovery)
GUI	PySide6 (Qt6 for Python, Fusion style, QTranslator zh_CN)
Config	Pydantic v2 + JSON/YAML/TOML
Retry	Built-in ProxyFailureClassifier + aiohttp_retry_fetch
Testing	pytest + pytest-asyncio + pytest-cov

Security

Atomic Writes — POSIX protocol (mkstemp → write → fsync → os.replace → chmod 0o600), modeled on SQLite WAL / PostgreSQL WAL / Git core.fsync
Concurrent Locking — fcntl.flock guards rules_state.json and sources.json RMW cycles, modeled on git .git/index.lock
DNS Rebinding Hard Block — 12 private/reserved IP ranges checked, preventing SSRF + DNS rebinding attacks
Unicode Sanitization — display_name/author/description auto-filter Bidi Override / C0 control chars / Interlinear Annotation, modeled on Unicode TR36 + Git ident validation
AI Injection Defense — Five-layer OWASP LLM01 defense (URL reconstruction, field validation, XML boundaries, output validation, user confirmation flow)
Extraction Layer Truncation — max_text_length moved upstream into _extract_value (all three branches), UTF-8 byte-aware truncation, preventing 50MB <div> memory amplification
Transform Two-Gate — Absolute ceiling + ratio ceiling, independent log events, each defending distinct attack vectors
URL Redaction — Proxy credentials and 15+ sensitive parameters (token, key, secret, jwt, etc.) automatically hidden in logs; source URLs limited to scheme://netloc
Chromium Log Suppression — --log-level=3 prevents credential leakage into browser debug output
API Key Protection — AIProfile __repr__ shows only first 8 characters + "...", API keys never appear in logs
File Permissions — Output reports chmod 600, Preferences file chmod 0o600
Cookie Validation — Only .json extension accepted, array format and entry structure verified
Remote Rule Sources — HTTPS-only, SHA256 manifest verification, on-demand download
Rule Regexes — re2 hard dependency ensures linear-time matching, zero ReDoS attack surface
