想用python写一个上传B站视频的脚本，用cookie登录并从
http://member.bilibili.com/ge...
获取一些必要的参数，然后用
http://vs103.upload.acgvideo....
上传视频，最后把一些视频信息post到
http://member.bilibili.com/v/...
最后能把视频post到指定账号下但总是显示转码失败（正常上传能成功），如图：

代码如下：

import requests
import json
import sys
import os
import re

class User():
    # some code
    
    def cookies_login(self):
        # cookie 登录
        
    def password_login(self):
        # 密码登录
        
    def upload(self, filename):
        # some code 
        try:
            response = self.session.get('http://member.bilibili.com/get_vupload_url', cookies=cookies)
        except:
            print('Cannot get response from server!')
        uploadresponse = json.loads(response.text)
        """
        print(response.text)
        {"url":"http://vs101.upload.acgvideo.com/upload.cgi?uid=43091594&filename=5896bf9e980e815d29a6b3b4d42d40cf&hash=7496003172e8a9a5bbe73beace2521ad",

        """
        try:        # if error happens...
