Python与微信——itchat包

itchat

一安装itchat

pip install itchat pip install echarts-python

二登陆并向文件传输助手发消息

``` import itchat 登录

itchat.login()

发送消息,filehelper是文件传输助手

itchat.send(u'hello', 'filehelper')

<h4 class='title'>二微信好友性别比例</h4>

获取好友列表

friends = itchat.get_friends(update=True)[0:]
print(friends)

初始化计数器，有男有女

male = female = other = 0

遍历这个列表，列表里第一位是自己，所以从“自己”之后计算 Sex中1是男士，2是女士 UserName, City, DisplayName, Province, NickName, KeyWord, RemarkName, HeadImgUrl, Alias，Sex

for i in friends[1:]:
sex =i["Sex"]
if sex ==1:
male += 1
elif sex == 2:
female += 1
else:
other += 1

总数算上

total = len(friends[1:])

print("男性好友：%.2f%%"%(float(male)/total100))
print("女性好友：%.2f%%"%(float(female)/total100))
print("其他：%.2f%%"%(float(other)/total*100))

<h4 class='title'>三微信设置自动回复</h4>

import itchat
import time

自动回复 封装好的装饰器，当接收到的消息是Text

@itchat.msg_register('Text')
def text_reply(msg):
# 当消息不是由自己发出
if not msg['FromUserName'] == myUserName:
# 发送一条提示给文件助手
itchat.send_msg(u'[%s]收到好友@%s的信息：%s '%(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(msg['CreateTime'])),
msg['User']['NickName'],
msg['Text']
),
'filehelper')
# 回复给好友
return u'[自动回复]您好，我现在有事不在，一会再和您联系。 已经收到您的的信息：%s ' % (msg['Text'])

if name == "main":
itchat.auto_login()
# 获取自己的UserName
myUserName = itchat.get_friends(update=True)[0]['UserName']
itchat.run()

先登录

itchat.login()

获取好友列表

friends = itchat.get_friends(update=True)[0:]

tlist = []
for i in friends:
# 获取签名
signature1 = i['Signature'].strip().replace('span', '').replace('class','').replace('emoji','')
# 正则过滤emoji表情
rep = re.compile("1fd.+")
signature = rep.sub('', signature1)
tlist.append(signature)

拼接字符串

text = ''.join(tlist)

jieba分词

word_list_jieba = jieba.cut(text, cut_all=True)
wl_space_split = ' '.join(word_list_jieba)

图片路径

projiect_path = os.path.dirname(os.path.dirname(file))
img_dir = os.path.join(projiect_path, 'images')
alice_coloring = np.array(Image.open(os.path.join(img_dir, 'ciyun.jpg')))

选择字体存放路径

my_wordcloud = WordCloud(
# 设置背景颜色
background_color='white',
max_words=2000,
# 词云形状
mask=alice_coloring,
# 最大字号
max_font_size=40,
random_state=42,
# 设置字体，不设置就会乱码
font_path=os.path.join(img_dir, 'simsun.ttc')
).generate(wl_space_split)

image_colors = ImageColorGenerator(alice_coloring)

显示词云图片

plt.imshow(my_wordcloud.recolor(color_func=image_colors))
plt.imshow(my_wordcloud)
plt.axis('off')
plt.show()

保存照片，并发送给手机

my_wordcloud.to_file(os.path.join(img_dir, 'myciyun.png'))
itchat.send_image(os.path.join(img_dir, 'myciyun.png'), 'filehelper')
