在给Tornado编写豆瓣API的类时, 在查看文档时, 发现其access_token
并不像其它网站那样是传在query或者body中的. 而是放入headers中.
即: headers["Authorization"] = Bearer <access_token>
搜索OAuth2.0 Bearer, 在RFC 6750中找到了详细介绍
标准中给出了3种access_token的使用方法:
标准推荐使用第一种方法. 第三种并不推荐, 因为access_token有可能泄漏.

不知什么时候手贱把beaglebone black刷成了Debian(Archlinux 没刷成功), 然后就放那了.
今天要做实验, 就搭了下NFS.
NFS Server 使用 Archlinux, 配置参见这里
client 使用 Debian. 需要安装 nfs-common package
配置 BB-black 联网:
在板子下输入命令:
/sbin/route add default gw 192.168.7.1
echo "nameserver 114.114.114.114" >> /etc/resolv.conf
在宿主机上输入:
sudo iptables -A POSTROUTING -t nat -j MASQUERADE ...Everytime one of the socket functions requires a pointer to a socket address structure, that pointer must be cast to a pointer to a generic socket address structure. This is because the socket functions predate the ANSI C standard, so the void * pointer type was not available in ...
在这里下载源代码，根据README进行编译．
在make libfree下时需要修改inet_ntop.c, 将第60行的
size_t size 改成 socklen_t size.
貌似Linux不支持4.4BSD style routing sockets, 所以不需要编译libroute
测试intro/daytimetcpcli: ./daytimetcpcli 216.171.112.36
而书上给的IP地址会一直block.
Then start reading the famous classic book.
“我不喜欢历史”
“你只是讨厌你的过去而已”
语言对人的伤害仅次于身体的伤害。
过去过去了，但它一直活在现在里。
过去的事情有时候连自己都记不清楚，于是现在的你粉饰着，装点着你的过去。 直到你自己相信那是一段美好的恍若你亲身经历。
但真实的过去永远在那，等待着机会吞噬你，吞噬你亲近的人。
过去永远支配着现在的你，而现在又将过去。
