python的requests实现文件上传,脚本如下【将url、header、data、filename、filepath替换成对应的即可】:
from urllib3 import encode_multipart_formdata
import requests
def post_files(url,header,data,filename,filepath):
"""
:param files: (optional) Dictionary of ``'name': file-like-objects`` (or ``{'name': file-tuple}``) for multipart encoding upload.
``file-tuple`` can be a 2-tuple ``('filename', fileobj)``, 3-tuple ``('filename', fileobj, 'content_type')``
or a 4-tuple ``('filename', fileobj, 'content_type', custom_headers)``, where ``'content-type'`` is a string
defining the content type of the given file and ``custom_headers`` a dict-like object containing additional headers
to add for the file.
"""
data['file']= (filename,open(filepath,'rb').read())
encode_data = encode_multipart_formdata(data)
data = encode_data[0]
header['Content-Type'] = encode_data[1]
r = requests.post(url, headers=header, data=data)
print(r.content)
if __name__=="__main__":
#url,filename,filepath string
#header,data dict
print(post_files("url",{"header":"value"},{"data":"value"},"filename","filepath"))
