工作中会有一些需要并发测试的场景，例如：两人同时操作一条数据，此时需要验证结果是否符合预期
最初是借助jmeter来进行并发测试，建2个线程组，每个线程组中各放一个接口，启动时会同时执行个线程组中的接口，从而实现并发测试的目的
但是每次都要打开jmeter，用起来不太方便，所以就尝试用python来实现接口并发测试，然后再写个前端页面
所以本次实现以下功能：
1、后端在django框架下，基于python实现接口并发测试
2、前端页面基于百度amis低代码平台实现
一、后端逻辑实现
用python自带的库concurrent.futures，它提供ThreadPoolExecutor，使之能够并发执行函数(来自ChatGPT)
ChatGPT给出的示例代码如下
上述代码中，make_request()函数是需要并发执行的函数，ThreadPoolExecutor设置并发请求，示例中传入的参数urls是一个list
根据自己的实际需求改造一下示例代码：
首先我的目标是对2个接口请求进行并发测试，所以会从前端传入2个接口的请求url、headers、请求参数，把前端参数组合成list，大致如下：列表包裹字典，一个字典是一组参数，标记好url、headers、payload
param_data = [
{"url": url_1, "headers": headers_1, "payload": payload_1},
{"url": url_2, "headers": headers_2, "payload": payload_2}
]新建一个concurrency_test.py文件
make_request()函数改为如下形式，它接收的参数data就是一组字典参数
from concurrent.futures import ThreadPoolExecutor
import requests
def make_request(data):
r = requests.post(url=data["url"], headers=data["headers"], json=data["payload"], verify=False)
# print(r.json())
return r.json()然后再定义一个主函数
def multi_processing(data):
with ThreadPoolExecutor(max_workers=2) as executor:
results = list(executor.map(make_request, data))
# print(results)
res = []
for i, result in zip(data, results):
res.append(
result["message"] + "；traceId=" + result["traceId"]
)
print(res)
return resmax_workers控制并发数量(线程数)，map()中接收并发函数以及它所需要的参数
再新建一个视图函数concurrency_test_views.py
from django.http import JsonResponse,HttpResponse
import json
from app.api.concurrency_test import *
from django.views.decorators.http import require_http_methods
def concurrent(request):
url_1 = request.GET.get("url_1")
headers_1 = json.loads(request.GET.get("header_1"))
payload_1 = json.loads(request.GET.get("body_1"))
url_2 = request.GET.get("url_2")
headers_2 = json.loads(request.GET.get("header_2"))
payload_2 = json.loads(request.GET.get("body_2"))
param_data = [
{"url": url_1, "headers": headers_1, "payload": payload_1},
{"url": url_2, "headers": headers_2, "payload": payload_2}
]
res = multi_processing(param_data)
dict_res = {
"res1": res[0],
"res2": res[1]
}
return JsonResponse(dict_res, json_dumps_params={'ensure_ascii': False})
# return HttpResponse(res)最后配置好路由，这个接口就写好了
----------------------------------------------
接下来开始写前端，前端布局大致如下
这个页面是直接用amis写的，这部分是用的现成的组件，不再细说，贴下代码
前端amis代码
