文章标签 python 微信群聊 python抓取微信群消息怎么屏蔽 List json ci 文章分类 Python 后端开发

早些日子有人问我我的微信里面有一共多少朋友，我就随后拉倒了通讯录最下面就找到了微信一共有多少位好友。然后他又问我，这里面你认识多少人？

这一句话问的我很无语。一千多个好友我真的不知道认识的人有多少。他还紧追着不放了，你知道你微信朋友的男女比例嘛？你知道你微信朋友大部分来自什么地方吗？

以下的代码内容只涉及一些简单的Python知识，稍微有一点Python知识的朋友都可以读下去。如果你没有Python的知识你可能需要去学习一下Python，当然你也可以不用学，搭建好Python的环境就好，期间可能需要用到一些库需要自己去解决一下，在下文中也会详细诉述。

第一步：首先抓取微信朋友的资料

既然是要做统计和分析，第一步就是微信朋友的所有可以抓取的资料抓取出来。所谓有用的资料大致来说有以下几个内容：

昵称、微信号、城市、性别、星标好友、头像、个性签名、备注

每一项或者联合项可以做的统计

性别：好友性别统计

城市：好友地区分布

备注+昵称：大致统计认识的好友比例

头像：人脸识别

那么如何抓取呢？这里使用了之前有一位大神写的如何找出被删的好友的代码，修改部分为从提取json数据截断，对返回的json数据进行提取分别找到了以下的所需要的信息：

代码修改为：

所返回的json结果如下图所示

昵称、微信号、城市、性别、星标好友、头像、个性签名、备注。提取以上信息，对头像图片进行下载，并对数据进行简单的清洗等等，最后一列为微信号不方便显示。

第二步：性别统计和地区分布

使用python的pandas科学计算库进行简单的统计，如果你没有用过，可以转至如下链接进行安装学习：【原】十分钟搞定pandas

只要掌握了非常简单的pandas只是就可以继续往下看做以下统计

(1)、所有好友的男女比例

(2)、所有好友的城市分布

(3)、统计认识的朋友以及占所有朋友的百分比

统计方法：所有朋友 - 没有备注的朋友 - 备注与昵称相同的朋友

(4)、统计认识的朋友中的男女比例

统计方法：对三的结果再进行男女划分即可得到结果

把结果做成简单的图表(主要使用了百度的 echarts 作图)

使用地图慧江苏省好友分布，这个编码我不知怎么回事，可能是浏览器问题，回头我用其它浏览器查看一下。

最后再生成省份好友分布地图

最后运用opencv的图像识别进行人像识别，统计微信好友中用人像作为头像的好友人数。OpenCV的全称是：Open Source Computer Vision Library。OpenCV是一个基于BSD许可(开源)发行的跨平台计算机视觉库，可以运行在Linux、Windows和Mac OS操作系统上。它轻量级而且高效——由一系列 C 函数和少量 C++ 类构成，同时提供了Python、Ruby、MATLAB等语言的接口，实现了图像处理和计算机视觉方面的很多通用算法。

如果你对opencv不是很了解，你可以按照以下的链接进行学习。

你可以去它的官网：http://opencv.org/ (需要有一定的英语知识)

国内也有一些比较好的博客资源，比如以下两个

如下开始是对抓取的朋友头像进行遍历识别是否含有人脸，代码如下。

#!/usr/bin/env python
'''
face detection using haar cascades
USAGE:
facedetect.py [--cascade ] [--nested-cascade ] []
'''
# Python 2/3 compatibility
from __future__ import print_function
import numpy as np
import cv2
# local modules
from video import create_capture
from common import clock, draw_str
def detect(img, cascade):
rects = cascade.detectMultiScale(img, scaleFactor=1.3, minNeighbors=4, minSize=(30, 30),
flags=cv2.CASCADE_SCALE_IMAGE)
if len(rects) == 0:
return []
rects[:,2:] += rects[:,:2]
return rects
def draw_rects(img, rects, color):
for x1, y1, x2, y2 in rects:
cv2.rectangle(img, (x1, y1), (x2, y2), color, 2)
if __name__ == '__main__':
import sys, getopt
print(__doc__)
count = 0
for i in range(1,1192):
print(str(i))
args, video_src = getopt.getopt(sys.argv[1:], '', ['cascade=', 'nested-cascade='])
try:
video_src = video_src[0]
except:
video_src = 0
args = dict(args)
cascade_fn = args.get('--cascade', "../../data/haarcascades/haarcascade_frontalface_alt.xml")
nested_fn = args.get('--nested-cascade', "../../data/haarcascades/haarcascade_eye.xml")
cascade = cv2.CascadeClassifier(cascade_fn)
nested = cv2.CascadeClassifier(nested_fn)
cam = create_capture(video_src, fallback='synth:bg=../data/friend/friendImage/image'+str(i)+'.jpg:noise=0.05')
ret, img = cam.read()
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
gray = cv2.equalizeHist(gray)
rects = detect(gray, cascade)
vis = img.copy()
draw_rects(vis, rects, (0, 255, 0))
if not nested.empty():
if len(rects) == 0:
print('none')
else:
count = count + 1
print(str(count))
input()

执行以上代码统计出最后的结果

使用人像做头像的好友：59 因此不使用人像的1133，看来使用人像的人还是很少的。

运行提取人像头像的代码最后提取出的头像如下所示，不得不说Python的库真是十分的有用。(因为涉及到隐私，所以这里不会展示过多的头像)

最近仍然在研究签名以及头像的可用之处，也是欢迎大家一起学习交流。同时希望以上的内容可以提升一下大家的学习兴趣。关于微信好友的更多挖掘会不断进行。

(1)、人像头像与年龄之间的关系(由于微信没有年龄，于是想通过知乎进行推算)

(2)、个性签名与年龄性格之间的关系

(3)、微信号中所包含信息推算年龄层次，预测当前微信号年龄
