使用解析器

解析器是一种将非结构化数据转换为与后端兼容的结构化数据的方法。将解析器与Olostep API（抓取、爬取、批处理）结合使用，可以将任何网站转换为API调用，以返回所需的JSON。当你需要从相同网站以重复的方式获取大规模数据时，解析器是理想的选择。这种方法相比于LLM提取显著更具成本效益且速度更快，并且仅返回所需的JSON。我们为热门网站和用例提供预构建的解析器。你也可以使用仪表板在几分钟内使用LLM创建自己的解析器，或者请求我们的团队为你创建。

预构建解析器

我们为热门网站提供了几个预构建的解析器：

谷歌搜索：@olostep/google-search
亚马逊产品：@olostep/amazon-it-product
提取电子邮件：@olostep/extract-emails
提取日历：@olostep/extract-calendars
提取社交信息：@olostep/extract-socials
TikTok数据提取：请联系我们获取解析器ID
谷歌新闻：请联系我们获取解析器ID
谷歌地图：请联系我们获取解析器ID

示例用法

import requests
import json

endpoint = "https://api.olostep.com/v1/scrapes"
payload = {
    "formats": ["json"],
    "parser": {"id": "@olostep/google-search"},
    "url_to_scrape": "https://www.google.com/search?q=alexander+the+great&gl=us&hl=en",
    "wait_before_scraping": 0,
}
headers = {
    "Authorization": "Bearer <YOUR-API-KEY>",
    "Content-Type": "application/json"
}

response = requests.request("POST", endpoint, json=payload, headers=headers)
print(json.dumps(response.json(), indent=4))

响应格式

当你使用解析器格式向Olostep API发出请求时，你将收到如下示例的JSON响应：
