Python版本为2.7，使用requests包

# coding=utf-8
import requests
 
url = "http://******upload.action"
fileName = 'C:\\Users\\seanzou\\Desktop\\img\\1.jpg'
img = open(fileName, 'rb')
#注意这里一定要设置图片类型
file={'file':(fileName, img, 'Content-Type: image/jpg')}
params={
    'file_model': 1,
    'name_model': 1,
    'siteUrl': '******',
    'isPublish': '******',
    'director': '******',
    'userId': 1
}
header={
    'Accept': '*/*',
    'Accept-Encoding': 'gzip,deflate',
    'Accept-Language': 'zh-CN,zh;q=0.9',
    'User-Agent': 'Mozilla/5.0',
}
try:
    #也可不设置head属性
    result = requests.post(url, data=params, files=file, headers=header)
    print result.text
except Exception as e:
    print(e)
finally:
    img.close()

执行结果如下

我们debug一下脚本来看一下请求的head

{
	'Content-Length': '7499',
	'Accept-Language': 'zh-CN,zh;q=0.9',
	'Accept-Encoding': 'gzip,deflate',
	'Accept': '*/*',
	'User-Agent': 'Mozilla/5.0',
	'Connection': 'keep-alive',
	'Content-Type': 'multipart/form-data; boundary=666ba8e246f86930402e10964c73bcc9'
}

再来看一下请求的body

--666ba8e246f86930402e10964c73bcc9
Content-Disposition: form-data; name="file_model"

--666ba8e246f86930402e10964c73bcc9
