🔥 什么是Firecrawl?
Firecrawl是一个API服务,它接受一个URL,对其进行爬取,并将其转换为干净的markdown或结构化数据。我们爬取所有可访问的子页面,并为每一个页面提供干净的数据。无需站点地图。
Pst. 嘿,你,加入我们的星标用户吧 :)
如何使用?
我们的托管版本提供易于使用的API。您可以在此处找到游乐场和文档。如果您愿意,也可以自托管后端。

}
}
使用Python SDK
安装Python SDK
pip install firecrawl
-
py
爬取一个网站
from firecrawl import FirecrawlApp
app = FirecrawlApp(api_key="YOUR_API_KEY")
crawl_result = app.crawl_url('mendable.ai', {'crawlerOptions': {'excludes': ['blog/*']}})
for result in crawl_result:
print(result['markdown'])
爬取单个URL
要爬取单个URL,使用scrape_url方法。它接受URL作为参数,并返回作为字典的爬取数据。
url = 'https://example.com'
scraped_data = app.scrape_url(url)
从URL提取结构化数据
使用LLM提取,您可以轻松地从任何URL提取结构化数据。我们支持pydantic架构,以便您更容易使用。以下是使用方法:
from pydantic import BaseModel, Field
from typing import List
class ArticleSchema(BaseModel):
title: str
points: int
by: str
commentsURL: str
class TopArticlesSchema(BaseModel):
top: List[ArticleSchema] = Field(..., max_items=5, description="Top 5 stories")
data = app.scrape_url('https://news.ycombinator.com', {
'extractorOptions': {
'extractionSchema': TopArticlesSchema.schema_json(),
'mode': 'llm-extraction'
},
'pageOptions':{
'onlyMainContent': True
}
})
print(data["llm_extraction"])
搜索查询
执行网络搜索,检索顶部结果,从每个页面提取数据,并返回其markdown格式内容。
query = 'What is Mendable?'
search_result = app.search(query)
使用Node SDK
安装
要安装Firecrawl Node SDK,您可以使用npm:
npm install
@mendable
/
firecrawl
-
js
使用
1.从firecrawl.dev获取API密钥 2.并将API密钥设置为名为FIRECRAWL_API_KEY的环境变量,或将其作为参数传递给FirecrawlApp类。
爬取单个URL
要带错误处理爬取单个URL,请使用scrapeUrl方法。它接受URL作为参数,并返回作为字典的爬取数据。
try {
const url = 'https://example.com';
const scrapedData = await app.scrapeUrl(url);
console.log(scrapedData);
} catch (error) {
console.error(
'Error occurred while scraping:',
error.message
);
}
爬取网站
要带错误处理爬取网站,请使用crawlUrl
方法。它接受起始URL和可选参数作为参数。params
参数允许您为爬取作业指定额外选项,如最大页面数、允许的域和输出格式。
const crawlUrl = 'https://example.com';
const params = {
crawlerOptions: {
excludes: ['blog/'],
includes: [], // 留空表示所有页面
limit: 1000,
},
pageOptions: {
onlyMainContent: true
}
};
const waitUntilDone = true;
const timeout = 5;
const crawlResult = await app.crawlUrl(
crawlUrl,
params,
waitUntilDone,
timeout
);
检查爬取状态
要带错误处理检查爬取作业状态,请使用checkCrawlStatus方法。它接受作业ID作为参数,并返回爬取作业的当前状态。
const status = await app.checkCrawlStatus(jobId);
console.log(status);
从URL提取结构化数据
使用LLM提取,您也可以轻松地从任何URL提取结构化数据。我们支持zod架构,以便您更容易使用。以下是使用方法:
import FirecrawlApp from "@mendable/firecrawl-js";
import { z } from "zod";
const app = new FirecrawlApp({
apiKey: "fc-YOUR_API_KEY",
});
// 定义架构以提取内容
const schema = z.object({
top: z
.array(
z.object({
title: z.string(),
points: z.number(),
by: z.string(),
commentsURL: z.string(),
})
)
.length(5)
.describe("Top 5 stories on Hacker News"),
});
const scrapeResult = await app.scrapeUrl("https://news.ycombinator.com", {
extractorOptions: { extractionSchema: schema },
});
console.log(scrapeResult.data["llm_extraction"]);
搜索查询
使用search方法,您可以在搜索引擎中搜索查询,并获取顶部结果以及每个结果的页面内容。该方法接受查询作为参数,并返回搜索结果。
const query = 'what is mendable?';
const searchResults = await app.search(query, {
pageOptions: {
fetchPageContent: true // 获取每个搜索结果的页面内容
}
});
