它不难



a）设置一个套接字 - 你需要主机，页面&port（也许这些可以作为参数传递） - 大约11行代码

b）使用来自（a）的套接字发出连接 - 1行代码

c） 你可能需要写一个GET [path] HTTP / 1.0和一个HOST语句到套接字

d）读取返回的数据从套接字 - 2行代码可以覆盖（d&e）

e）将结果从（d）写入文件或stdout

f）关闭并整理 - 2-3行代码



没有评论，大约20-30行代码



我们打算为你写作业/作业

a) set up a socket - for which you'll need host, page & port (maybe these can be passed as parameters) - about 11 lines of code
b) issue a connect using the socket from (a) - 1 line of code
c) [edit - whoops, its a web server you're speaking to] you may need to write a GET [path] HTTP/1.0 and a HOST statement to the socket
d) read the data that comes back from the socket - 2 lines of code can cover (d & e)
e) either write the results from (d) to a file or stdout
f) close and tidy up - 2-3 lines of code

Without comments, its about 20-30 lines of code
