 login_res=self.s.post(url=login_url,headers=self.headers,data=form_data,proxies=self.proxies).text
        self.cookie_name="cookies" + self.username + '.txt'

        new_cookie_jar = cookielib.LWPCookieJar(self.username + '.txt')

        # 将转换成字典格式的RequestsCookieJar（这里我用字典推导手动转的）保存到LWPcookiejar中
        requests.utils.cookiejar_from_dict({c.name 

: c.value for c in self.s.cookies}, new_cookie_jar)

        # 保存到本地文件
        new_cookie_jar.save(self.cookie_name, ignore_discard=True, ignore_expires=True)

TypeError: string indices must be integers, not str

Answer 1

字符串索引必须为整数，而不是字符。
你的问题在于requests.get()函数的cookies参数，必须为一个字典或cookiejar对象，而你却赋值了一个字符串。
