一、python实现http服务调用

服务端开发后通常需要做功能测试、性能测试，通常postman、curl等作功能测试使用，长跑服务性能postman并不太适合，如用c++实现http client，开发效率太低效，本文介绍一种用python来实现http server的测试。

二、代码实现

1. http 申请token代码

import json
import requests
import time
import threading
import time
from threading import Thread
import sys                                                                  
import signal
#-*- coding: UTF-8 -*-
requests.packages.urllib3.disable_warnings()

username="admin"
password="admin123"

sever_ip="10.20.40.80"
my_token=""

def allocToken(platform_ip):
    url='http://%s/user/allocToken' %(platform_ip)
    headers = {
        "Content-Type": "application/json",
    }
    data={
        "validateMethod":"name+password",
        "username":str(username),
        "userpassword":str(password),
        "refreshInterval":3600,        
        "requestid":"1"       
        }
    response = requests.post(url, headers=headers, verify=False, data=json.dumps(data))
    resp = json.loads(response.text)
    print("token: "+ str(resp["token"]))
    return resp["token"]



def ConcurrencyAllocToken(sequence,platform_ip):
    while True:
        try:
            start = time.time()
            my_token=allocToken(platform_ip)
            t_exec = time.time() - start
            print(str(sequence) + " call alloc token used: " + str(t_exec))
            break
        except:
            break        


if __name__=="__main__":  
    cpucores = 1
    for i in range(cpucores):
        thread = Thread(target=ConcurrencyAllocToken, args=(i,sever_ip,))
        thread.start()
        time.sleep(1)

2. 结果如下：

{
    "requestid": "1",
    "resultDesc": "成功",
    "resultcode": 0,
    "token": "BA680401-92D5-535A-38D4-633C8456ED9E",
    "userInfo": {
        "userid": "5aa2d40b-87f6-4a82-abf3-212df0677309",
        "loginName": "admin",
        "userName": "admin123"
    }
}

总结

本文实现了最简单的http申请token的流程，可以做其他的扩展使用。
