第一次在优达学城这个平台学习 很喜欢 英文教学 记录！！！
很有趣的学习体验 推荐同学们使用 像我很穷嘛 就看单项课程就是free【本文是自己的记录 不便于直接阅读的那种自己瞎记录的笔记】
课程 1：Requests & Responses
1.introduction
【】
Interactive Python
Git–>could download course materials from the Github repository
deploying
inverstigate
browsers
Namp–>install nact(我在Ubuntu实现的 有趣)2.Your first web server
解答：Applications that you use in a web browser, and mobile services, are both likely to use HTTP. But low-level network tests such as ping do not.
【】
–user interface for web technology
handle incoming requests
Exercise: Running your first web server（很有趣）
access
这一段话非常有用对于一些总是不明所以的（比如我用PHP的建立连接的时候） 现在我就稍微懂了一些web server的原理了
大家可以简单看一下翻译 还是要自己多理解英文比较好
That’s what should happen, anyhow: You get a 404 error code. 404 is the famous HTTP code for “Not Found”, meaning that the resource the client asked for isn’t there.
好了 断断续续学习了一个多小时吧
不过真的喜欢这个课程

3.Parts of a URI
URI schemes
URI for Uniform Resource Identifier.
URL or Uniform Resource Locator.
（mailto is used for links to email addresses. data is used to put a piece of hardcoded data directly into a web page, for instance a small image. magnet is used for links to some file-sharing services such as BitTorrent. However, there is no such thing as a postal URI; if you want to send postal mail from the Web you still need to print it out and put it in the mailbox yourself.）
（example.net is the hostname. /google.com/ponies is the path. Even though google.com is a perfectly good hostname, in this particular URI it is just appearing as part of the path.【只是作为路径的一部分出现】）Relative URI references
Other URI parts 4.Hostnames and ports
