您需要使用网站HTML中上传文件的name属性。例子:

autocomplete="off" name="image">

你看到name="image">?你可以在上传文件的网站的HTML中找到它。您需要使用它来上传Multipart/form-data文件

脚本:

import requests

site = 'https://prnt.sc/upload.php' # the site where you upload the file
filename = 'image.jpg'  # name example

这里，在image的位置，用HTML添加上传文件的名称

up = {'image':(filename, open(filename, 'rb'), "multipart/form-data")}

如果上传需要点击按钮进行上传，可以这样使用:

data = {
     "Button" : "Submit",
}

然后启动请求

request = requests.post(site, files=up, data=data)

完成，文件上传成功

我试图用python 3中的请求模块发送一个请求到URL_server。 这对我来说很管用:

# -*- coding: utf-8 *-*
import json, requests

URL_SERVER_TO_POST_DATA = "URL_to_send_POST_request"
HEADERS = {"Content-Type" : "multipart/form-data;"}

def getPointsCC_Function():
  file_data = {
      'var1': (None, "valueOfYourVariable_1"),
      'var2': (None, "valueOfYourVariable_2")
  }

  try:
    resElastic = requests.post(URL_GET_BALANCE, files=file_data)
    res = resElastic.json()
  except Exception as e:
    print(e)

  print (json.dumps(res, indent=4, sort_keys=True))

getPointsCC_Function()

地点:

URL_SERVER_TO_POST_DATA =我们要发送数据的服务器 报头=发送的报头 file_data =发送的参数

import requests
# assume sending two files
url = "put ur url here"
f1 = open("file 1 path", 'rb')
f2 = open("file 2 path", 'rb')
response = requests.post(url,files={"file1 name": f1, "file2 name":f2})
print(response)

这是在多部分请求中发送文件的一种方法

import requests
headers = {"Authorization": "Bearer <token>"}
myfile = 'file.txt'
myfile2 = {'file': (myfile, open(myfile, 'rb'),'application/octet-stream')}
url = 'https://example.com/path'
r = requests.post(url, files=myfile2, headers=headers,verify=False)
print(r.content)

其他方法

import requests

url = "https://example.com/path"

payload={}
files=[
  ('file',('file',open('/path/to/file','rb'),'application/octet-stream'))
]
headers = {
  'Authorization': 'Bearer <token>'
}

response = requests.request("POST", url, headers=headers, data=payload, files=files)

print(response.text)

我都测试过了，两者都很好。

import json
import os
import requests
from requests_toolbelt import MultipartEncoder

AUTH_API_ENDPOINT = "http://localhost:3095/api/auth/login"

def file_upload(path_img, token ):
    url = 'http://localhost:3095/api/shopping/product/image'
    name_img = os.path.basename(path_img)

    mp_encoder = MultipartEncoder(
        fields={
            'email': 'mcm9@gmail.com',
            'source': 'tmall',
            'productId': 'product_0001',
            'image': (name_img, open(path_img, 'rb'), 'multipart/form-data')
        #'spam': ('spam.txt', open('spam.txt', 'rb'), 'text/plain'),
        }
    )

    head = {'Authorization': 'Bearer  {}'.format(token),
            'Content-Type': mp_encoder.content_type}

    with requests.Session() as s:
        result = s.post(url, data=mp_encoder, headers=head)

    return result

def do_auth(username, password, url=AUTH_API_ENDPOINT):
    data = {
        "email": username,
        "password": password
    }

    # sending post request and saving response as response object
    r = requests.post(url=url, data=data)

    # extracting response text
    response_text = r.text

    d = json.loads(response_text)
    # print(d)

    return d


if __name__ == '__main__':
    result = do_auth('mcm4@gmail.com','123456')
    token = result.get('data').get('payload').get('token')
    print(token)
    result = file_upload('/home/mcm/Pictures/1234.png',token)
    print(result.json())

自从编写了以前的一些答案之后，请求已经发生了变化。在Github上看看这个问题的更多细节，这条评论是一个例子。

简而言之，files参数接受一个字典，键为表单字段的名称，值为字符串或2、3或4长度的元组，如请求快速入门中的POST一个多部分编码文件部分所述:

>>> url = 'http://httpbin.org/post'
>>> files = {'file': ('report.xls', open('report.xls', 'rb'), 'application/vnd.ms-excel', {'Expires': '0'})}

在上面，元组的组成如下:

(filename, data, content_type, headers)

如果值只是一个字符串，文件名将与键相同，如下所示:

>>> files = {'obvius_session_id': '72c2b6f406cdabd578c5fd7598557c52'}

Content-Disposition: form-data; name="obvius_session_id"; filename="obvius_session_id"
Content-Type: application/octet-stream

72c2b6f406cdabd578c5fd7598557c52

如果值是一个元组，并且第一个条目是None，则filename属性将不包括在内:

>>> files = {'obvius_session_id': (None, '72c2b6f406cdabd578c5fd7598557c52')}

Content-Disposition: form-data; name="obvius_session_id"
Content-Type: application/octet-stream

72c2b6f406cdabd578c5fd7598557c52
