python接口测试中的异步调用

Posted 2020-12-16 只宅不技术

接口测试中可以可以使用httpx进行异步调用，下面对比一下异步调用和同步调用的速度

异步调用的代码如下

# 异步调用
import httpx
import asyncio
import time

async def request(client):
    resp = await client.get(\'http://httpbin.org/get\')
    result = resp.json()

async def main():
    async with httpx.AsyncClient() as client:
        # 100 次调用
        task_list = []
        for _ in range(100):
            req = request(client)
            task = asyncio.create_task(req)
            task_list.append(task)
        await asyncio.gather(*task_list)


if __name__ == "__main__":
    #开始
    start = time.time()
    asyncio.run(main())
    # 结束
    end = time.time()
    print(f\'异步：发送100次请求，耗时：{end - start}\')

结果为

 

 同步调用代码如下

# 同步调用
import time
import httpx


def make_request(client):
    resp = client.get(\'http://httpbin.org/get\')
    result = resp.json()

def main():
    session = httpx.Client()

    # 1000 次调用
    for _ in range(100):
        make_request(session)


if __name__ == \'__main__\':
    # 开始
    start = time.time()
    main()
    # 结束
    end = time.time()
    print(f\'同步：发送100次请求，耗时：{end - start}\')

结果为：
