1.环境搭建

1.1.安装visual studio code（vscode） 、python3

1.2.安装requests库

在终端输入pip3 install requests （适用于python3）


2.发送Post请求

导入 requests、json库

import requests
import json

url = 'https://127.0.0.1/dc-wisdom-manager/ipad/receptionDeskAuthor/login'     
data = {
    "loginName":"18888002222",
    "password":"chen@123",
    "identityType":1
}

# verify为https验证
res_post = requests.post(url,data,verify=False).json()

# 输出json格式
print(json.dumps(res_post,indent=4,ensure_ascii=False))


3.发送get请求

get_url = 'https://test-client.polyxfb.com/dc-wisdom-manager/app/api/sign/in?loginName=18766662233&password=Poly@123&identityType=1'   #案场登录

res_get =requests.get(get_url,verify=False).json()        #告诉程序为一个json格式

print(json.dumps(res_get,indent=4,ensure_ascii=False))   #使用josn库中dumps方法格式化

exit()


4.上传文件

上传图片

import json
import requests
from requests_toolbelt import MultipartEncoder   # 上传图片需要引入MultipartEncoder方法
import unittest

def file_upload(self):
        header = self.request_login()
        upload_url = "http://192.168.0.200/api/file/file/upload"
        upload_file = {
            'typeValue':'1',
            'file':('xmind.png',open('C:/Users/zeewain/Downloads/xmind.png','rb'),"image/png") 
        }
        m = MultipartEncoder(upload_file)
        header['Content-Type']=m.content_type
        upload_res = requests.post(upload_url,data=m,headers=header).json()
        upload_res = json.dumps(upload_res,indent=4,ensure_ascii=False)
        return upload_res


5.下载文件

dl_url = 'http://file.mukewang.com/apk/app/139/1642579764/imooc_8.1.6_10102001_android.apk?version=1642579767'

dl_res = requests.get(dl_url)
with open('imooc_8.1.6_10102001_android.apk','wb') as f:
    f.write(dl_res.content)

print(dl_res)

exit()


6.请求头加密串处理

引入库 import hashlib->

import hashlib
import requests
import json

imooc = 'imooc.com'
md5 = hashlib.md5()      # md5实例化对象
md5.update(imooc.encode('utf-8'))     # MD5加密并转码
res = md5.hexdigest()      #获取加密结果
print(res)

转换字符串加密

data = str({
    'user':'Cheney'
})
md5 = hashlib.md5()
md5.update(data.encode('utf-8'))
res1 = md5.hexdigest()
print(res1)

在请求头使用加密的变量

header = {
    'Host':'m.imooc.com',
    'Connection':'keep-alive',
    'Pragma':'no-cache',
    'Cache-Control':'no-cache',
    'Accept':'application/json, text/javascript, */*; q=0.01',
    'X-Requested-With':'XMLHttpRequest',
    'User-Agent':'Mozilla/5.0 (iPhone; CPU iPhone OS 11_0 like Mac OS X) AppleWebKit/604.1.38 (KHTML, like Gecko) Version/11.0 Mobile/15A372 Safari/604.1',
    'Referer':'https://m.imooc.com/',
    'Accept-Language':'zh-CN,zh;q=0.9',
    'token':res,
    'psid':res1
}

res = requests.get('https://m.imooc.com/api/search/searchword',headers=header,verify=False).json()
print(res)
