## 场景 ##

实现扫码登录微信并获取所有好友的昵称以及头像，并将所有头像

拼接成一张图片。

## 实现 ##

新建文件夹weixinImage

文件夹下新建文件weixinImge.py

# -*- 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)

## 效果 ##

![Image 1][]![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70][]

运行后会出现登录扫码，登录后等待结束。

## 注意 ##

使用了Python自带的IDLE,无法输出特殊字符。会报错:

UnicodeEncodeError: 'UCS-2' codec can't encode characters in position 8-8: Non-BMP character not supported in Tk

后来改为在Pycharm中运行

运行结束后

回到文件夹

则在wechat下是所有的好友头像，而wechat.png是拼接成的头像照片。
