除了使用性能測試工具進行性能測試，咱們也能夠直接用python多線程進行性能測試。html
下面，使用這幾個模塊，對一個查詢接口作性能測試：python
requests：發送http請求json
json：返回的字符串轉換成json格式api
threading：多線程多線程
time：統計時間app
具體實現過程見代碼及註釋。工具
import requests
import json
import threading
import time
# 定義請求基本地址
base_url = "http://127.0.0.1:8000"
success = 0
fail = 0
# 查詢線程
def get_guest_list_thread(start_user,end_user):
for i in range(start_user,end_user):
phone = 13800138000 + i
r = requests.get(base_url+'/api/get_guest_list/', params={'eid':1,'phone':phone})
# print(r.status_code) # 200
# print(r.content) # b'{"status": 200, "message": "success", "data": {"realname": "alen", "phone": "13800138000", "email": "alen@mail.com", "sign": false}}'
# print(r.json()) # {'status': 200, 'message': 'success', 'data': {'realname': 'alen', 'phone': '13800138000', 'email': 'alen@mail.com', 'sign': False}}
# print(type(r)) # <class 'requests.models.Response'> ,這個類型有json方法，不須要import json
# print(r) # <Response [200]>
# print(json.loads(r.content)) #須要import json，{'status': 200, 'message': 'success', 'data': {'realname': 'alen', 'phone': '13800138000', 'email': 'alen@mail.com', 'sign': False}}
result = r.json()
global success,fail
try:
if phone=='13800138000' or phone=='13800138001':
assert result['status'] == 20
success +=1
else:
assert result['status'] == 10022
success +=1
except AssertionError as e:
print('get error:'+str(phone))
fail +=1
# 5個線程，25個數據
# lists = {1:6, 6:11, 11:16, 16:21, 21:26} # 能夠這樣寫數據，也能夠經過下面生成
data = 25
n = 5
step = int(data/n)
lists = {}
for i in range(1,n+1):
lists[(i-1)*step+1]=i*step + 1
print(lists)
# 建立線程列表
threads = []
# 建立線程
for start_user,end_user in lists.items():
t = threading.Thread(target=get_guest_list_thread,args=(start_user,end_user)) # args是一個元組
threads.append(t)
if __name__ == '__main__':
# 開始時間
start_time = time.time()
# 啓動線程
for i in range(len(lists)):
threads[i].start()
for i in range(len(lists)):
threads[i].join()
# 結束時間
time.sleep(3) # 爲了更明顯看出用例執行耗時，加上休眠
end_time = time.time()
print("開始時間:"+str(start_time)+'>>>>>'+time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(start_time)))
print("結束時間:"+str(end_time)+'>>>>>'+time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(end_time)))
print('總共耗時:' + str(end_time - start_time))
print('總共耗時:%.2f'%(end_time - start_time)) # 保留兩位小數
print('測試經過用例數：{}， 測試失敗用例數：{}， 測試經過率爲：{}'.format(success,fail,str(success*100/(success+fail))+'%'))
結果：性能
