python 自动化测试数据并发送到http-nodejs server

Posted 2022-04-14 qianbo_insist

目的

使用python做自动化测试，使用python得numpy，pandas，http等库来post数据，并且自动产生随机数字，后转化成json上传，并用nodejs做server接收测试，当然也可以用go，java，都一样

1、产生随机数：

import time
x = random.randint(65,71)
print(x)

为了产生比较正常得随机心率数据，范围使用65到71

2、http post

两种方法，使用request 或者httpclient

import requests
 s = requests.session()
    #print(s.headers)
    headers1 = 
        'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:54.0) Gecko/20100101 Firefox/54.0',
        'Content-Type': 'application/json'
    
    response = s.post(url1,data=json1, headers=headers1,timeout=10)

超时时间设置为10s

3、json post

上传时需要json数据，需要将字典转换成json

import json
str = json.dumps('userid':1)
print(str)

使用dumps函数就可以立刻将python字典格式转化成json字符串

4、show me the code

import numpy as np
import random
import requests
import time
import pandas as pd
import json
import http.client,urllib.parse
url = "http://39.103.188.46:8082/hrv"
url1 = "http://127.0.0.1:8000/hrv"


def post2():
    str = json.dumps('userid':1)
    print(str)
    headers = "Content-type": "application/json","Accept": "text/plain"
    conn = http.client.HTTPConnection("127.0.0.1",8000)
    conn.request('POST', "/hrv", str, headers)
    response = conn.getresponse()
    print(response.status, response.reason)
    data = response.read().decode('utf-8')
    print(data)
    conn.close()

def post(datain):
    s = requests.session()
    #print(s.headers)
    headers1 = 
        'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:54.0) Gecko/20100101 Firefox/54.0',
        'Content-Type': 'application/json'
    
  
    #json = pd.DataFrame.to_json(datain)
    json1 = json.dumps(datain) # 转换为json
    response = s.post(url1,data=json1, headers=headers1,timeout=10)
    print(response)
    print(response.content)

data = 'Id': 116,'Type':3,'Device':'B00007','Data':[]
nowtime = time.mktime(time.localtime()) - 1000*60 *6 *60  # 往前推一个小时

number = 6 * 60 #一分钟6个数据，一共60分钟 360个数据
for i in range(number): 
    #x=np.append(x,)
    data['Data'].insert(0,'heart':random.randint(65,71), 'Time':nowtime+i*166)

post(data)

5、nodejs server

实际上我们使用得是go server 做心率服务，这里简单使用nodejs server来接收数据测试，测试人员可以简单使用python，nodejs，go 等做server

var express = require('express');
var cors = require('cors');
var app = express();//创建express实例
app.use(cors());//为了解决跨域问题
var http = require('http').Server(app);
//var httpget = require('http');
var bodyParser = require('body-parser');
app.use(bodyParser.json(limit: '1mb'));  
app.use(bodyParser.urlencoded(            
  extended: true
));
//var session = require('express-session');
/*
app.use(session(
    secret: 'secret',
    resave: true,// don't save session if unmodified
    saveUninitialized: false,// don't create session until something stored
    cookie: 
        maxAge: 1000 * 60 * 10 //过期时间设置(单位毫秒)
    
));
*/
app.use(express.static(__dirname));

app.post("/hrv",function(req,res)
	console.log(req.body);
	 res.send("ret:1");
);

 app.get("/",function(req,res)
     
     res.send("ret:ok");
 );

http.listen(8000, function () 
    console.log('listening on *:8000');
);

收到数据打印，如下图所示
