Python3: requests实现文件上传（对应postman form-data）

#coding:utf-8
from urllib3 import encode_multipart_formdata
import requests

url = "http://127.0.0.1/Pass-01/index.php"
data = {}
headers = {}
filename = 'name.png'  #上传至服务器后，用于存储文件的名称
filepath = r'C:\Users\master\Desktop\pp.jpg'  #当前要上传的文件路径
proxies = {
    "http": "http://127.0.0.1:8080",
    "https": "http://127.0.0.1:8080",
}
####
data['upload_file'] = (filename, open(filepath, 'rb').read())
data['submit']="提交"
encode_data = encode_multipart_formdata(data)
data = encode_data[0]
headers['Content-Type'] = encode_data[1]
# r = requests.post(url, headers=headers, data=data, timeout=5)
r = requests.post(url, headers=headers, data=data, proxies=proxies, timeout=5)
print(r.status_code)

　　上面的代码，我已经试验成功。
