生成随机的验证码图片（Python）

---

一、导入包

import random
from PIL import Image, ImageDraw, ImageFont

二、生成随机的验证码

def random_code(length=4):
    '''默认返回4位随机验证码，字符串'''
    code = ""
    characters = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890"
    for i in range(length):
        rand_char = random.choice(characters)
        code += rand_char
    return code

三、生成随机的rgb颜色

def random_color():
    """默认返回随机颜色，元组"""
    return random.randrange(256), random.randrange(256), random.randrange(256)

四、生成图片验证码

def image_code(width=120, height=30, point=100, line=4):
    '''生成图片验证码'''
    code = random_code()
    color = random_color()

    image = Image.new(mode='RGB', size=(width, height), color=(0, 0, 0))  # 背景图片
    draw = ImageDraw.Draw(image)
    font = ImageFont.truetype("arial.ttf", 28)  # 字体

    for i, ch in enumerate(code):
        draw.text([i * width / 4, 0], ch, fill=color, font=font)
    for _ in range(point):
        draw.point([random.randint(0, width), random.randint(0, height)], fill=random_color())  # 画点
    for _ in range(line):
        draw.line(
            (random.randint(0, width),
             random.randint(0, height),
             random.randint(0, width),
             random.randint(0, height)
             ),
            fill=random_color())  # 画线

    image.show()
    # image.save(r'')
