多语言支持的关键特性

核心技术实现

编码自动检测与处理

import chardet
from langdetect import detect
class EncodingProcessor:
    def detect_and_decode(self, content):
        # 自动检测编码
        detected = chardet.detect(content)
        encoding = detected['encoding'] or 'utf-8'
        try:
            decoded = content.decode(encoding)
        except UnicodeDecodeError:
            # 尝试常见编码
            for enc in ['utf-8', 'gbk', 'shift_jis', 'euc-kr']:
                try:
                    decoded = content.decode(enc)
                    break
                except:
                    continue
        # 检测语言
        try:
            language = detect(decoded[:1000])
        except:
            language = 'unknown'
        return decoded, language

语言特定的解析规则

class LanguageParserFactory:
    def get_parser(self, language, site_type):
        parsers = {
            'zh': {
                'news': ChineseNewsParser(),
                'forum': ChineseForumParser(),
                'ecommerce': ChineseEcommerceParser()
            },
            'en': {
                'news': EnglishNewsParser(),
                'blog': EnglishBlogParser()
            },
            'ja': JapaneseParser(),
            'ko': KoreanParser()
        }
        return parsers.get(language, {}).get(site_type, UniversalParser())

智能语言路由

class SmartCrawlerRouter:
    def __init__(self):
        self.language_strategies = {
            'zh': self._chinese_strategy,
            'en': self._english_strategy,
            'ja': self._japanese_strategy,
            'ko': self._korean_strategy
        }
    def route_request(self, url, content_type='html'):
        # 基于URL和内容类型选择策略
        language = self._detect_language_from_url(url)
        strategy = self.language_strategies.get(
            language, 
            self._universal_strategy
        )
        return strategy(url, content_type)

配置系统

多语言配置文件

  zh:
    name: 简体中文
    encoding: [utf-8, gbk, gb2312]
    stopwords: config/stopwords/zh.txt
    date_formats:
      - "YYYY年MM月DD日"
      - "YYYY-MM-DD"
    char_ranges:
      - [0x4E00, 0x9FFF]  # 常用汉字
  en:
    name: English
    encoding: [utf-8, iso-8859-1]
    stopwords: config/stopwords/en.txt
    date_formats:
      - "MMMM DD, YYYY"
      - "DD/MM/YYYY"
  ja:
    name: 日本語
    encoding: [utf-8, shift_jis, euc-jp]
    text_processing: japanese_processor.JapaneseTextProcessor

站点配置文件

{
  "sites": {
    "zh_news": {
      "language": "zh",
      "selectors": {
        "title": ["h1.article-title", ".news-title"],
        "content": [".article-content", "#content"],
        "date": [".publish-time", "time"],
        "author": [".author", ".editor"]
      },
      "pagination": {
        "type": "url_param",
        "pattern": "page={page}"
      }
    },
    "en_blog": {
      "language": "en",
      "dynamic": true,
      "requires_js": true,
      "wait_time": 3
    }
  }
}

数据处理管道

多语言文本处理管道

class MultilingualPipeline:
    def __init__(self):
        self.pipeline = [
            EncodingNormalizer(),
            LanguageDetector(),
            TextCleaner(),
            EntityExtractor(),
            SentimentAnalyzer(),
            TranslationProcessor(optional=True)
        ]
    def process(self, text, target_language=None):
        result = {'original': text}
        for processor in self.pipeline:
            if isinstance(processor, TranslationProcessor) and target_language:
                result = processor.process(result, target_language)
            else:
                result = processor.process(result)
        return result

翻译集成

class TranslationManager:
    def __init__(self):
        self.translators = {
            'google': GoogleTranslator(),
            'deepl': DeepLTranslator(),
            'baidu': BaiduTranslator(),
            'youdao': YoudaoTranslator()
        }
    def translate(self, text, src_lang, tgt_lang, translator='auto'):
        if translator == 'auto':
            translator = self._select_best_translator(src_lang, tgt_lang)
        return self.translators[translator].translate(
            text, src_lang, tgt_lang
        )

部署和使用示例

基本使用

from openclaw import MultilingualClaw
# 初始化多语言爬虫
claw = MultilingualClaw(
    languages=['zh', 'en', 'ja'],
    default_language='auto'
)
# 抓取多语言网站
results = claw.crawl([
    'https://example.cn',      # 中文
    'https://example.com',     # 英文
    'https://example.co.jp'    # 日文
])
# 统一处理
processed = claw.process_all(
    results,
    target_language='zh'  # 可选：统一翻译为中文
)

CLI工具

# 基本抓取
openclaw crawl --url https://example.com --lang en
# 批量抓取
openclaw batch --config sites.yaml --parallel 5
# 翻译模式
openclaw crawl --url https://example.jp --translate-to zh
# 导出多格式
openclaw export --format json,csv,xlsx --lang all

高级功能

动态语言适配

class AdaptiveCrawler:
    def __init__(self):
        self.language_models = {}
        self.load_language_models()
    def adaptive_parse(self, html, url):
        # 1. 检测语言
        language = self.detect_language(html)
        # 2. 加载对应模型
        if language not in self.language_models:
            self.language_models[language] = self.train_model(language)
        # 3. 智能解析
        parser = self.create_parser(language, html)
        return parser.extract(html)

分布式多语言爬取

# 使用Celery进行分布式任务分发
@app.task(queue='crawler_tasks')
def crawl_language_site(url, language):
    # 根据语言分发到不同的worker
    if language in CJK_LANGUAGES:
        return crawl_cjk_site.delay(url, language)
    elif language in EUROPEAN_LANGUAGES:
        return crawl_european_site.delay(url, language)
    else:
        return crawl_universal_site.delay(url)
