多线程-http请求

• 线程基类

import threading
class base_thread(threading.Thread):
    def __init__(self, func):
        threading.Thread.__init__(self)
        self.func = func
        #print(type(self.func))
    def run(self):
        self.func

• http请求

#-*- coding: utf-8 -*-
import requests
import json
class ConfigHttp:
    def __init__(self, host, port,headers):
        self.host = host
        self.port = port
        self.headers = headers
    # 封装HTTP GET请求方法
    def get(self, url, params):
        # params = urllib.parse.urlencode(params)
        url = "http://"+self.host+":"+self.port+url
        try:
            r = requests.get(url, params=params, headers=self.headers)
            r.encoding = 'UTF-8'
            return r.text
        except Exception:
            print('no json data returned')
            return {}
    # 封装HTTP POST请求方法,支持上传图片
    def post(self, url, data, files=None):
        data = eval(data)
        url = 'http://' + self.host + ':' + str(self.port)+url
        r =requests.post(url, files=files, data=data)
        print(data)
        json_response = r.text
        return json_response

• 简单调用,当然最好的方式是再次封装一层

import ConfigHttp   
def sample_request():
    headers= {'Accept':'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8','User-Agent':'Mozilla/5.0 (Windows NT 6.1; rv:29.0) Gecko/20100101 Firefox/29.0'}
    cf = ConfigHttp(host="www.xxx.com",port=80,headers=headers)
    #cf.get(url="/api/getuserinfo",{"id":2})
    cf.get(url="/api/getuserinfo?id=2")

• 多线程调用

def multi_thread():
    count = 100
    threads = []
    for i in range(0, 100):
        threads.append(base_thread(sample_request()))
    for j in range(0, 100):
        threads[j].start()
    for k in range(0, 100):
        threads[k].join()
