wxpy、pyinstalller 库的使用。

上午发了张我微信近 2000 位好友的头像拼图,让大伙儿看能不能快速找到自己的头像,没想到反响很强烈,引得阵阵惊呼与膜拜,没有料到。

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1555740721340" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;"> image

有没有犯密集恐惧症?这并不震撼,如果你有 5000 位好友的话,做出来的图看着会更刺激些。

看完了图,你可能想知道这个图咋做出来的,不会是我闲着无聊把把好友头像一个个保存下来再用 PS 拼的吧?

自然不是了,Python 做的,是不是觉得没有 Python 干不了的事儿。其实,这种图很早就有人玩过了,不过下面还是来说说怎么做出来,这样你也可以做一个自己微信好友的图片墙。

有两种方法,一种简单的,不用接触 Python 代码,一种稍微复杂点,需要写代码。

先说简单的方法,只需要两步:运行程序然后扫微信二维码就行了。剩下的交给程序自己蹦跶,泡杯茶在电脑前等待几分钟左右就可以得到图片,具体的等待时间视微信好友数量而不同,我近 2000 好友,用时 10 分钟左右。

一个简单的操作示意图:

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1555740721342" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;"> image

<input class="pgc-img-caption-ipt" placeholder="图片描述(最多50字)" value="" style="box-sizing: border-box; outline: 0px; color: rgb(102, 102, 102); position: absolute; left: 187.5px; transform: translateX(-50%); padding: 6px 7px; max-width: 100%; width: 375px; text-align: center; cursor: text; font-size: 12px; line-height: 1.5; background-color: rgb(255, 255, 255); background-image: none; border: 0px solid rgb(217, 217, 217); border-radius: 4px; transition: all 0.2s cubic-bezier(0.645, 0.045, 0.355, 1) 0s;"></tt-image>

几分钟后就可以得到上面的图片了。

其实到这儿就完了,是不是很简单。

你要感兴趣怎么实现的,可以往下看用 Python 代码怎么实现的,代码不长,60 行就可以搞定。

核心是利用三个个库:

  • wxpy 库,用于获取好友头像然后下载
  • Pillow 库,用于拼接头像
  • Pyinstaller 库,用来打包 Python 程序成 exe 文件

程序通过三个函数实现,第一个 creat_filepath 函数生成图片下载文件路径,第二个 save_avatar 函数循环获取微信好友头像然后保存到本地,第三个 joint_avatar 函数就是把头像拼接成一张大图。

完整代码如下:

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"># -- coding: utf-8 --
from wxpy import *
import math
from PIL import Image
import os

创建头像存放文件夹

def creat_filepath():
avatar_dir = os.getcwd() + "\wechat\"
if not os.path.exists(avatar_dir):
os.mkdir(avatar_dir)
return avatar_dir

保存好友头像

def save_avatar(avatar_dir):
# 初始化机器人,扫码登陆
bot = Bot()
friends = bot.friends(update=True)
num = 0
for friend in friends:
friend.get_avatar(avatar_dir + '\' + str(num) + ".jpg")
print('好友昵称:%s' % friend.nick_name)
num = num + 1

拼接头像

def joint_avatar(path):
# 获取文件夹内头像个数
length = len(os.listdir(path))
# 设置画布大小
image_size = 2560
# 设置每个头像大小
each_size = math.ceil(2560 / math.floor(math.sqrt(length)))
# 计算所需各行列的头像数量
x_lines = math.ceil(math.sqrt(length))
y_lines = math.ceil(math.sqrt(length))
image = Image.new('RGB', (each_size * x_lines, each_size * y_lines))
x = 0
y = 0
for (root, dirs, files) in os.walk(path):
for pic_name in files:
# 增加头像读取不出来的异常处理
try:
with Image.open(path + pic_name) as img:
img = img.resize((each_size, each_size))
image.paste(img, (x * each_size, y * each_size))
x += 1
if x == x_lines:
x = 0
y += 1
except IOError:
print("头像读取失败")
img = image.save(os.getcwd() + "/wechat.png")
print('微信好友头像拼接完成!')
if name == 'main':
avatar_dir = creat_filepath()
save_avatar(avatar_dir)
joint_avatar(avatar_dir)
</pre>

可以直接在运行程序文件,也可以用 Pyinstaller 文件打包后运行。这里额外说一下 pyinstaller 打包的方法和闭坑指南。

不要直接在系统中用 pyinstaller 打包,否则打包出来的 exe 文件会很大。建议在虚拟环境中打包,打包出来的 exe 文件会小很多, 10MB 左右。

虚拟环境创建很简单,简单说一下步骤:

1 安装 pipenv 和 pyinstaller 包,用于后续创建虚拟环境和打包程序:

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">pip install pipenv
pip install pyinstaller # 已安装就不用安装了
</pre>

2 选择一个合适的目录作为 Python 虚拟环境,运行:

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">pipenv install # 创建虚拟环境
pipenv shell # 创建好后,进入虚拟环境
</pre>

3 安装程序引用的库,上面程序引用了四个库:wxpy、math、os 和 PIL,一行代码就可以完成安装。

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">pipenv install wxpy math os
</pre>

4 这里要额外注意 PIL 的安装,现在不用 PIL 库,而是用 Pillow 库取代,所以安装 Pillow 库就行。但不要安装最新的 6.0.0 版本,否则可能会遇到各种错误,例如:PIL 无法识别下载的 jpg 头像文件。

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">OSError: cannot identify image file <ImageFieldFile: images
</pre>

正确的安装方法是安装低版本,经尝试安装 4.2.1 版本没有问题,安装命令:

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">pipenv install Pillow==4.2.1
</pre>

5 然后打包程序就可以了:

<pre spellcheck="false" style="box-sizing: border-box; margin: 5px 0px; padding: 5px 10px; border: 0px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-numeric: inherit; font-variant-east-asian: inherit; font-weight: 400; font-stretch: inherit; font-size: 16px; line-height: inherit; font-family: inherit; vertical-align: baseline; cursor: text; counter-reset: list-1 0 list-2 0 list-3 0 list-4 0 list-5 0 list-6 0 list-7 0 list-8 0 list-9 0; background-color: rgb(240, 240, 240); border-radius: 3px; white-space: pre-wrap; color: rgb(34, 34, 34); letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">pyinstaller -F C:\Users\sony\Desktop\wechat_avatar.py

程序路径要改成你电脑上的路径

-F 表示生成单个 exe 文件,方便运行

</pre>

运行如下:

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1555740721356" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;"> image

<input class="pgc-img-caption-ipt" placeholder="图片描述(最多50字)" value="" style="box-sizing: border-box; outline: 0px; color: rgb(102, 102, 102); position: absolute; left: 187.5px; transform: translateX(-50%); padding: 6px 7px; max-width: 100%; width: 375px; text-align: center; cursor: text; font-size: 12px; line-height: 1.5; background-color: rgb(255, 255, 255); background-image: none; border: 0px solid rgb(217, 217, 217); border-radius: 4px; transition: all 0.2s cubic-bezier(0.645, 0.045, 0.355, 1) 0s;"></tt-image>

运行命令,1 分钟左右若显示 successfully 字样表示程序打包成功:

<tt-image data-tteditor-tag="tteditorTag" contenteditable="false" class="syl1555740721358" data-render-status="finished" data-syl-blot="image" style="box-sizing: border-box; cursor: text; color: rgb(34, 34, 34); font-family: "PingFang SC", "Hiragino Sans GB", "Microsoft YaHei", "WenQuanYi Micro Hei", "Helvetica Neue", Arial, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: pre-wrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: block;"> image

<input class="pgc-img-caption-ipt" placeholder="图片描述(最多50字)" value="" style="box-sizing: border-box; outline: 0px; color: rgb(102, 102, 102); position: absolute; left: 187.5px; transform: translateX(-50%); padding: 6px 7px; max-width: 100%; width: 375px; text-align: center; cursor: text; font-size: 12px; line-height: 1.5; background-color: rgb(255, 255, 255); background-image: none; border: 0px solid rgb(217, 217, 217); border-radius: 4px; transition: all 0.2s cubic-bezier(0.645, 0.045, 0.355, 1) 0s;"></tt-image>

接着在程序目录下找到 wechat_avatar.exe 文件,然后按照第一种方法那样运行就行了。

以上就是用 Python 制作微信好友图片墙的方法。
