1.python 上传多个文件

 1.1

pip install requests_toolbelt

from requests_toolbelt.multipart.encoder import MultipartEncoder

list_urls = ['https://sun9-63.userapi.com/c638920/v638920705/1a54d/xSREwpakJD4.jpg',
 'https://sun9-28.userapi.com/c854024/v854024084/1160d8/LDMVHYgguAw.jpg',
 'https://sun9-54.userapi.com/c854220/v854220084/111f66/LdcbEpPR6tg.jpg',
 'https://sun9-40.userapi.com/c841420/v841420283/4c8bb/Mii6GSCrmpo.jpg']

headers0={
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.127 Safari/537.36'
}
fields = [("files",(i.split('/')[-1],requests.get(i,headers=headers0).content)) for i in list_urls]
#fields.append(("boundary","--WebKitFormBoundary9K7xUkVGzyQA6e6h"))
multipart_encoder = MultipartEncoder(fields)
headers2 = {"Content-Type": multipart_encoder.content_type}
resp = requests.post("http://127.0.0.1:9315/send_images", headers=headers2, data=multipart_encoder)
print(resp.text)

  1.2 上传多个文件并提交表单

        

list_urls = ['https://sun9-63.userapi.com/c638920/v638920705/1a54d/xSREwpakJD4.jpg',
             'https://sun9-28.userapi.com/c854024/v854024084/1160d8/LDMVHYgguAw.jpg',
             'https://sun9-54.userapi.com/c854220/v854220084/111f66/LdcbEpPR6tg.jpg',
             'https://sun9-40.userapi.com/c841420/v841420283/4c8bb/Mii6GSCrmpo.jpg']

headers0 = {
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/100.0.4896.127 Safari/537.36'
}
fields = [("files", (i.split('/')[-1], requests.get(i, headers=headers0).content)) for i in list_urls]

data = {"label":"上传表单"}
response = requests.post('http://127.0.0.1:9315/send_images',files=fields,data=data)
print(response.text)

2. 接收单个文件

image_url='https://sun9-40.userapi.com/c841420/v841420283/4c8bb/Mii6GSCrmpo.jpg'

files={'file':(image_url.split('/')[-1],requests.get(image_url,headers=headers0).content))}

data={'label':'文件'}

res = requests.post(‘"http://127.0.0.1:9315/send_one_image"’,data=data,files=files)

print(res.text)
