###效果图
下载本项目到本地,打开项目主目录,打开命令行,输入:
pip install -r requirements.txt
等待安装完成,输入:
python wxImage.py
出现如下二维码:
用手机微信右上角的扫一扫,确认登陆即可。
稍等片刻,你打开手机微信,找到信息栏的微信传输助手,会看到如下:
python:
- itchat(用于爬取头像)
- pillow(用于拼接图片)
##源码详解
首先登陆python版本微信itchat,生成二维码:
itchat.auto_login(enableCmdQR=True)
获取好友列表:
friends = itchat.get_friends(update=True)[0:]
然后使用itchat的get_head_img(userName=none)函数来爬取好友列表的头像,并下载到本地:
num = 0
for i in friends:
img = itchat.get_head_img(userName=i["UserName"])
fileImage = open(user + "/" + str(num) + ".jpg",'wb')
fileImage.write(img)
fileImage.close()
num += 1
计算出每张头像缩小后的尺寸(由于为了拼接之后可以用来作为为微信头像,所以合成的图片大小都是640 * 640的,因为微信头像大小就是640 * 640)
计算每张头像缩小后的边长(默认为正方形):
eachsize = int(math.sqrt(float(640 * 640) / numPic))
计算合成图片每一边分为多少小边:
numline = int(640 / eachsize)
缩小并拼接图片:
x = 0
y = 0
for i in pics:
try:
#打开图片
img = Image.open(user + "/" + i)
except IOError:
print("Error: 没有找到文件或读取文件失败")
else:
#缩小图片
img = img.resize((eachsize, eachsize), Image.ANTIALIAS)
#拼接图片
toImage.paste(img, (x * eachsize, y * eachsize))
x += 1
if x == numline:
x = 0
y += 1
保存图片到本地:
toImage.save(user + ".jpg")
在微信的文件传输助手发合成后的图片给使用者:
itchat.send_image(user + ".jpg", 'filehelper')
