如何将Python的requests GET请求转为带参数的asyncio异步请求？

不需要手动拼接URL，aiohttp的get方法和requests完全一样支持params参数来传递查询参数，直接复用你现有的payload即可。

完整实现代码 #

import asyncio
from aiohttp import ClientSession

async def fetch_wikidata(search_term):
    base_url = "https://www.wikidata.org/w/api.php"
    payload = {
        "action": "query",
        "list": "search",
        "srsearch": search_term,
        "language": "en",
        "format": "json",
        "origin": "*",
    }
    async with ClientSession() as session:
        async with session.get(base_url, params=payload) as resp:
            return await resp.json()

# 并行执行多个请求
async def main():
    terms = ["Python", "asyncio", "Wikidata"]
    tasks = [fetch_wikidata(term) for term in terms]
    results = await asyncio.gather(*tasks)
    for term, res in zip(terms, results):
        print(f"{term}的搜索结果：", res.get('query', {}).get('search', []))

if __name__ == "__main__":
    asyncio.run(main())

核心要点 #

• session.get的params参数会自动将payload中的键值对编码为URL查询字符串，和requests的逻辑完全一致，无需手动拼接。
• 使用await resp.json()直接获取解析后的JSON对象，比read()返回字节流更高效便捷。
• 通过asyncio.gather可以批量创建异步任务，实现真正的并行请求，大幅提升多请求场景下的效率。
