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

async ==》发音athink、表示异步

await ==》饿威特

# 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:异步:发送100次请求,耗时:1.1421504020690918

 

# 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()

# 100 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}')

同步:发送100次请求,耗时:24.393028020858765
