1、requests-toolbelt官方文件：https://pypi.org/project/requests-toolbelt/

2、環境安裝

pip install requests-toolbelt

3、

multipart/form-data傳檔案

from requests_toolbelt import MultipartEncoder
import requests
 
m = MultipartEncoder(
    fields={'field0': 'value',
           'field1': 'value',
            'field2': ('檔名稱', open('檔案地址/file.py', 'rb'), 'text/plain')}
    )
 
r = requests.post('http://httpbin.org/post',
                  data=m,
                  headers={'Content-Type': m.content_type})

multipart/form-data表單提交（傳非檔案）　

from requests_toolbelt import MultipartEncoder
import requests
 
m = MultipartEncoder(
       fields={'field0': 'value',
               'field1': 'value'})
 
r = requests.post('http://httpbin.org/post',
                  data=m,
                  headers={'Content-Type': m.content_type})　

multipart/form-data表單提交（傳圖片）

import requests
from requests_toolbelt.multipart import MultipartEncoder

image = open(r"D:\xxx.jpg", "rb"),  # 讀取模式為二進位制讀取方式

m = MultipartEncoder(fields={
    # "file":("圖片的名稱.jpg","圖片的二進位制流","image/jpeg")
    "file": ("xxxx.jpg", image, "image/jpeg")
})

r = requests.post('http://httpbin.org/post',data=m,headers={'Content-Type': m.content_type})

引數也可以使用list型別

from requests_toolbelt import MultipartEncoder
import requests
 
m = MultipartEncoder(
    fields = [
    ('source', ('f1.ext', f1, 'application/x-example-mimetype'),
    ('source', ('f2.ext', f2, 'application/x-example-mimetype'),
]
    )
 
r = requests.post('http://httpbin.org/post',
                  data=m,
                  headers={'Content-Type': m.content_type})
