本节目标：实现步骤：
今天突然想闲逛逛CSDN博客，看到有个排行榜，就点进去了。
其实早就知道有这个地，以前都不怎么来看。
然后，仔细一看，疑问和兴趣就都来了：
这积分太出人意料了，是吧。
它背后的原因是什么呢？
点进去：
看左边的红线上，这就让人吃惊了，难道是CSDN的官方？ 能自己随便给积分？
然后，看他置顶文章，标题太吸引人了，不得不看。
反正是人各有志吧，其实我觉得CSDN还是不错的，虽然现在竞争对手也多了，估计日子也不好过。
既然这人不是官方， 那他的积分哪来的，于是，很快找到了原因：
这人确实有才，于是好奇心越发大了。
他怎么得的这段呢，这个工具是什么，我现在是不清楚的。
所以就整理了一下http模块。
不过，先看了一下cgi模块：
<span style="font-size:18px;">> cgi
BytesIO, FeedParser, FieldStorage, MiniFieldStorage, StringIO,
TextIOWrapper, closelog, dolog, escape, html,
initlog, locale, log, logfile, logfp,
maxlen, nolog, os, parse, parse_header,
parse_multipart, parse_qs, parse_qsl, print_arguments, print_directory,
print_environ, print_environ_usage, print_exception, print_form, sys,
tempfile, test, urllib, valid_boundary, warn,
import cgi;
def tmp():
print('写入开始 >>>');
array = ['cgi'];
fout = open('output.txt', 'w');
for i in range(len(array)):
s = array[i];
fout.write('> ' + s+'\n');
try:
a = dir(eval(s));
b = [];
for j in range(len(a)):
if (a[j][0] == '_'):
continue;
else:
b.append(a[j]);
for j in range(len(b)):
if (j == 0):
fout.write('\t');
fout.write(b[j]+', ');
if (j%5 == 4):
fout.write('\n\t');
fout.write('\r\n');
except:
pass;
fout.close();
print('写入完毕');</span>然后看看http模块：
<span style="font-size:18px;">> http.client

def tmp():
print('写入开始 >>>');
array = ['http.client', 'http.client.HTTPConnection',
'http.client.HTTPResponse'];
fout = open('output.txt', 'w');
for i in range(len(array)):
s = array[i];
fout.write('> ' + s+'\n');
try:
a = dir(eval(s));
b = [];
for j in range(len(a)):
if (a[j][0] == '_'):
continue;
else:
b.append(a[j]);
for j in range(len(b)):
if (j == 0):
fout.write('\t');
fout.write(b[j]+', ');
if (j%5 == 4):
fout.write('\n\t');
fout.write('\r\n');
except:
pass;
fout.close();
print('写入完毕');
</span>
抓http头的工具：
<span style="font-size:18px;">#使用http.client模块

</span>但我的这个cookie好像和他那个不一样，他怎么得到的呢？
于是我又整理了一下cookie，在python 3.*里，现在是在httlp下面的子文件了。
<span style="font-size:18px;">> http.cookies
BaseCookie, CookieError, Morsel, SimpleCookie, re,
string,
> http.server
BaseHTTPRequestHandler, CGIHTTPRequestHandler, DEFAULT_ERROR_CONTENT_TYPE, DEFAULT_ERROR_MESSAGE, HTTPServer,
SimpleHTTPRequestHandler, argparse, copy, email, executable,
html, http, io, mimetypes, nobody,
nobody_uid, os, posixpath, select, shutil,
socket, socketserver, sys, test, time,
urllib,
import http.client;
import http.cookiejar;
import http.cookies;
import http.server;
def tmp():
print('写入开始 >>>');
array = ['http.client', 'http.client.HTTPConnection',
'http.client.HTTPResponse', 'http.cookiejar',
'http.cookies', 'http.server'];
fout = open('output.txt', 'w');
for i in range(len(array)):
s = array[i];
fout.write('> ' + s+'\n');
try:
a = dir(eval(s));
b = [];
for j in range(len(a)):
if (a[j][0] == '_'):
continue;
else:
b.append(a[j]);
for j in range(len(b)):
if (j == 0):
fout.write('\t');
fout.write(b[j]+', ');
if (j%5 == 4):
fout.write('\n\t');
fout.write('\r\n');
except(Except, e):
print(e);
fout.close();
print('写入完毕');</span>整理这个的目的是想看一下上面那个http头里抓到的cookie是不是正解，
于是又用urllib库重新抓了一遍：

这人是这样刷分的，当然现在肯定是不行了，行也不要刷，这积分其实并没有什么利益在内
让它真实点更好。
这人太有才了，这个第一拿的大家心服口服，于是就又去他现在的博客逛了一圈，
看能不能扫到点什么好东西。
结果呢，是也有点，但不多。
比如一些计算机网络方面的东西：
这位同学的东西搜刮了一遍后，我就又回到了这个排行榜第二名，
打开一看，这位比上一位就没法比了，这纯粹是一小号用了那个bug。
那就来看第三位吧：
看左边的红线，这要以怎样的速度写博客，才能有这样惊人的数字呢。
再仔细一看，这人也很有才，只不过不是代码，而是思维：
再仔细一看，这位的博文早就不更了，早已是人去楼空。
不得不说，CSDN光凭能让这前两位，一个有才的刷分者，一个纯粹的刷分者，
以及一个只说理论，不谈技术的业界理论大师牢牢坐稳这前三名的位置，
就这份气度和度量就让阿伟觉得，CSDN确实可靠，毕竟，这就是赤祼祼的打脸啊。
本节到此结束。
