Exercism 练习

将单个 Exercism 练习概览页面解析为结构化 JSON，包含其标题、难度以及以文本和 HTML 呈现的完整说明。

API 用法

在 Crawling API 请求中添加 &scraper=exercism-exercise。在 url 参数中对目标 URL 进行 URL 编码。

curl 'https://api.crawlbase.com/?token=YOUR_TOKEN' \
  --data-urlencode 'url=https://exercism.org/tracks/ruby/exercises/two-fer' \
  --data-urlencode 'scraper=exercism-exercise' -G
from crawlbase import CrawlingAPI

api = CrawlingAPI({'token': 'YOUR_TOKEN'})
res = api.get(
    'https://exercism.org/tracks/ruby/exercises/two-fer',
    {'scraper': 'exercism-exercise'}
)

import json
data = json.loads(res['body'])
const { CrawlingAPI } = require('crawlbase');
const api = new CrawlingAPI({ token: 'YOUR_TOKEN' });

const res = await api.get(
  'https://exercism.org/tracks/ruby/exercises/two-fer',
  { scraper: 'exercism-exercise' }
);
const data = JSON.parse(res.body);
require 'crawlbase'
api = Crawlbase::API.new(token: 'YOUR_TOKEN')

res = api.get('https://exercism.org/tracks/ruby/exercises/two-fer', scraper: 'exercism-exercise')
data = JSON.parse(res.body)

示例输入 URL

url 参数支持任意 Exercism 练习概览页面 - 即 /tracks/<track>/exercises/<slug> 的页面。例如：

https://exercism.org/tracks/ruby/exercises/two-fer
https://exercism.org/tracks/python/exercises/leap
https://exercism.org/tracks/go/exercises/hello-world
https://exercism.org/tracks/rust/exercises/grains
