requests--文件上传，文件下载

文件上传

在做接口自动化的时候，有时需要上传文件，比如更改头像等等，在request里，通过files参数来上传

import requests

base_url = 'http://httpbin.org'
file = {'file': open(r'E:0.jpg', 'rb')}
r = requests.post(base_url + '/post', files=file)

print(r.text)  

文件下载

第一种方式

import requests


def dowload_file(file_path):
    headers = {"Referer": "https://xx315.xx315.nex"}
    cookie = {"Cookie": "ASP.NET_SessionId=bij"}
    
    r = requests.get(url='https://xx315.xx315',
                     cookies=cookie,
                     headers=headers,
                     stream=True)
    
    if r.status_code == 200:
        with open(file_path, 'wb') as f:
            for chunk in r.iter_content(chunk_size=1024):
                f.write(chunk)


dowload_file('F:\123.xlsx')

注意：

文件如果不存在，会在当前目录下生成一个文件，有内容会清空在写入

第二种方式

import requests
import shutil


def download_file_raw(file_path):
    url = 'https://xx315.xx315.net/Ashx/Export'
    cookie = {"Cookie": 'ASP.NET_SessionId=sjl8'}
    r = requests.get(url=url,
                     cookies=cookie,
                     stream=True
                     )

    if r.status_code == 200:
        with open(file_path, 'wb') as f:
            r.raw.decode_content = True
            shutil.copyfileobj(r.raw, f)


download_file_raw('F:\123.xlsx')
