要从文本文件内的URL检索JSON文件,通常涉及以下几个基础概念和技术:
以下是一个使用Python进行异步请求的示例代码:
import aiohttp
import asyncio
import json
async def fetch_json(url):
async with aiohttp.ClientSession() as session:
async with session.get(url) as response:
return await response.json()
async def main(file_path):
urls = []
with open(file_path, 'r') as file:
for line in file:
urls.append(line.strip())
tasks = [fetch_json(url) for url in urls]
results = await asyncio.gather(*tasks)
for result in results:
print(json.dumps(result, indent=4))
# 运行示例
file_path = 'urls.txt'
asyncio.run(main(file_path))
通过以上方法,可以有效地从文本文件内的URL检索JSON文件,并处理常见的错误情况。
