requests-toolbelt

1.官方文档地址：requests-toolbelt官方文档

2.环境安装

pip install requests-toolbelt

multipart/form-data传文件

from requests_toolbelt import MultipartEncoder
import requests

m = MultipartEncoder(
    fields={'field0': 'value',
           'field1': 'value',
            'field2': ('filename', open('file.py', 'rb'), 'text/plain')}
    )

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

multipart/form-data表单提交（传非文件）

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})

多个文件参数重复

1.参数重复的时候，就不用字典了，用list类型

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})
