python pycurl模块上传图片的函数：
复制代码 代码示例:
def upload_img(self, mypic):
'''
upload the image to the remote server.
'''
storage = StringIO()
c = pycurl.Curl()
values = [
("upload_file[]", (pycurl.FORM_FILE, str(mypic)))
]
c.setopt(c.URL, self.upload_url)
c.setopt(c.WRITEFUNCTION, storage.write)
c.setopt(c.HTTPPOST, values)
c.perform()
c.close()
content = storage.getvalue()
print content
以上用到了python pycurl模块，代码中mypic就是一个本地图片的路径，storage变量用于存储post后返回的相应信息。
