说明

使用python请求http接口

GET 请求

注：发送请求，模似请求头，浏览器信息查看，google上打开标签，输入about:version即可

def get(self, url, param=None, headers=None, cookies=None):
        res = None
        if headers is None:
            headers = {
                "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
                "Accept-Encoding": "gzip, deflate, sdch",
                "Accept-Language": "zh-CN,zh;q=0.8",
                "Cache-Control": "max-age=0",
                "Upgrade-Insecure-Requests": "1",
                "User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.109 Safari/537.36"
            }
        if cookies is None:
            res = requests.get(url=url, data=json.dumps(param),
                               headers=headers, cookies=cookies)
        else:
            res = requests.get(url=url, data=json.dumps(param),
                               headers=headers)
        #print("res=>", res.text)
        if res.status_code == 200:
            return res.text
        else:
            return None

POST 请求

同理也是简单调用

def post(self, url, param=None, headers=None, cookies=None):
        if headers is None:
            headers = {
                "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
                "Accept-Encoding": "gzip, deflate, sdch",
                "Accept-Language": "zh-CN,zh;q=0.8",
                "Cache-Control": "max-age=0",
                "Upgrade-Insecure-Requests": "1",
                "User-Agent": "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/72.0.3626.109 Safari/537.36"
            }
        res = None
        #print("param=",param)
        #json_data = json.dumps(param,ensure_ascii=False) #.encode("utf-8")
        json_data = json.dumps(param)
        #print("json_data=",json_data)
        if cookies is None:
            res = requests.post(url=url, data=json.dumps(param),
                                headers=headers, cookies=cookies)
        else:
            res = requests.post(url=url, data=json.dumps(param),
                                headers=headers)
        res.encoding = 'utf-8'      
        if res.status_code == 200:
            return res.text
        else:
            return None

使用类封装

import requests
import json
import re


class HttpUtil:

    def get(self, url, param=None, headers=None, cookies=None):
        xxxx_与上相同

    def post(self, url, param=None, headers=None, cookies=None):
        xxxx_与上相同

    # 测试
    def test_http(self):
        url = 'http://localhost:8090/pcrm/crm/sale'
        retJson = self.get(url)
        #print("json:", retJson)
        data = json.loads(retJson)
        text = data.get("data")
        #print("test=>", text)
        #retData = json.loads(text)
        total = text.get("total")
        print("total:", total)
        text2 = text.get("records")
        #print("test2=>", text2)
        count = 0
        if text2:
            for cust in text2:
                count = count + 1
                print("列表数据"+str(count)+":", cust)
        # if html:


#调用代码
if __name__ == "__main__":
    httpTest = HttpUtil()
    httpTest.test_http()
