Sample code for concurrency testing after flask deployment in Python

After deployment, check the concurrency supported by flask. Let’s take a look at 300 concurrency. Up the code

import threading, time, requests
url = ""total = 0
suc = 0
fail = 0
exception = 0
maxtime=0
mintime=100gt3=0
lt3=0class RequestThread(threading.Thread):def __init__(self, thread_name):  
        threading.Thread.__init__(self)  
        self.test_count = 0def run(self):
        self.test_performace()def test_performace(self):  global totalglobal sucglobal failglobal exceptionglobal gt3global lt3try:  
                st = time.time()  
                conn = requests.get(url)
                res = conn.status_codeif res== 200:
                    total+=1suc+=1else:
                    total+=1fail+=1time_span = time.time()-st  print ('%s:%f\n'%(self.name,time_span)  )
                self.maxtime(time_span)  
                self.mintime(time_span)  if time_span>3:
                    gt3+=1else:
                    lt3+=1except Exception as e:  print (e  )
                total+=1exception+=1def maxtime(self,ts):  global maxtimeprint (ts)if ts>maxtime:
                maxtime=tsdef mintime(self,ts):  global mintimeif ts<mintime:
                mintime=tsprint (&#39;===========请求开始===========&#39;  )
start_time = time.time()
thread_count = 100i = 0  
while i <= thread_count:  
    t = RequestThread("线程：" + str(i))
    t.start()  
    i += 1  t=0while total<thread_count|t>20:print ("总数:%d,成功数:%d,失败:%d,异常:%d\n"%(total,suc,fail,exception)  )print (url)
        t+=1time.sleep(1)print (&#39;===========task end===========&#39;)print ("总数:%d,成功:%d,失败:%d,异常:%d"%(total,suc,fail,exception))print (&#39;响应最大时间:&#39;,maxtime)print (&#39;响应最小时间&#39;,mintime)print (&#39;大于3秒的响应:%d,占比:%0.2f&#39;%(gt3,float(gt3)/total))print (&#39;小于3秒:%d,占比:%0.2f&#39;%(lt3,float(lt3)/total))

Look at Baidu request response

What about mine?

It’s pretty good. It supports concurrency, but it’s not very accurate. You can refer to it. You can also use this for interfaces
