@Registering 请问一下，post里面的once数据是什么呀？

@gcc2000 好的

@Registering 还是之前那个错误什么SSL错误

@Registering 安装了呀，奇怪呢！！！

@Registering 改成我自己的了，我的是2.7.8，还是不行呢

怎么我用楼主的程序出现错误：

@luoyibu 嗯，目前还没用到bs，因为连登陆都没成功呢，，，，我在网上查了好多，但无功而返，大神能帮下忙么？我可以把账号密码分享给您

@qaulau 我用fiddler抓包也发现了这个地址，但是打开是404错误，应该不是这个地址吧？

@lichifeng 您指的是类似scrapy这样的框架么
