本篇文章给大家分享了python中使用PIL制作并验证图片验证码的具体代码以及说明，需要的朋友参考下吧。

									#string模块自带数字、字母、特殊字符变量集合，不需要我们手写集合

									import string

									import random

									import os

									import uuid

									import settings

									from PIL import Image, ImageDraw, ImageColor, ImageFilter, ImageFont

									class Code(object):

									 # 生成随机生成数字或字母

									 def random_hexdigits(self, len=1):

									 return random.sample(string.hexdigits, len)

									 # 生成干扰字符

									 def punctuation(self, len=1):

									 return tuple(random.sample(string.punctuation, len))

									 # 定义干扰字符颜色

									 def random_color(self, min=64, max=255):

									 return tuple((random.randint(min, max) for i in range(3)))

									 # 生成验证码

									 def creat_code(self, width=80, height=24, color=(192, 192, 192)):

									 image = Image.new('RGB', (width, height), color)

									 #建议下载几款字体，变换下风格，我在setting粒定义了static路径，这里就直接导入了

									 font = ImageFont.truetype(os.path.join(settings.STATICPATH, 'fonts/Lora-Regular.ttf'), 20)

									 draw = ImageDraw.Draw(image)

									 self.fill_color(draw, image, 5)

									 self.fill_dischar(draw, image, 10)

									 code = self.fill_char(draw, image, 4, 10, font)

									 image_name = '{}.jpeg'.format(uuid.uuid4().hex)

									 image_path = os.path.join(settings.STATICPATH, 'code/{}'.format(image_name))

									 print(image_path)

									 image.save(image_path)

									 return {'code': code, 'image_path': image_path}

									 # 填充颜色

									 def fill_color(self, draw, image, interval):

									 for i in range(0, image.width, interval):

									  for j in range(0, image.height, interval):

									  draw.point((i, j), fill=self.random_color())

									 # 填充验证码

									 def fill_dischar(self, draw, image, interval):

									 for i in range(0, image.width, interval):

									  dis = self.punctuation()

									  j = random.randrange(3, image.height - 3)

									  draw.text((i, j), dis[0], fill=self.random_color(64, 255))

									 # 填充验证码

									 def fill_char(self, draw, image, num, interval, font):

									 code = ''

									 for i in range(num):

									  cha = self.random_hexdigits()

									  code += str(cha[0])

									  j = random.randrange(0, 5)

									  # print(cha)

									  # print(image.width*(i/num)+interval,j)

									  draw.text((image.width * (i / num) + interval, j), cha[0], fill=self.random_color(32, 127), font=font)

									 return code

									if __name__ == "__main__":

									 code = Code()

									 print(code.creat_code())

flask路由配置

									import os

									from flask import Flask, Response

									from flask import render_template

									from utils.code import Code

									app = Flask(__name__)

									@app.route('/')

									def Register():

									 return render_template('verify.html')

									@app.route('/codes/')

									def code():

									 infor = Code().creat_code()

									 image_path = infor["image_path"]

									 code = infor['code']

									 print(image_path)

									 with open(image_path, 'rb') as f:

									  image_content = f.read()

									 os.remove(image_path)

									 return Response(image_content, mimetype='jpeg')

									if __name__ == '__main__':

									 app.run(debug=True)

前端配置

									<div class='form-row'>

									  <form id="email_register_form" method="post" autocomplete="off">

									   <div class="form-group ">

									    <label>邮&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;箱</label>

									    <input type="text" id="id_email" name="email" value="None" placeholder="请输入您的邮箱地址"/>

									   </div>

									   <div class="form-group ">

									    <label>密&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;码</label>

									    <input type="password" id="id_password" name="password" value="None" placeholder="请输入6-20位非中文字符密码"/>

									   </div>

									   <div class="form-group captcha1 ">

									    <label>验&nbsp;证&nbsp;码</label>

									    <img src="/codes/" alt="captcha" title="点击切换" class="captcha"

									      onclick="this.src='codes/?'+Math.random()"/>

									    <input autocomplete="off" id="id_captcha_1" name="captcha_1" height="30px" type="text">

									   </div>

									   <input class="btn btn-green" id="jsEmailRegBtn" type="submit" value="注册"/>

									  </form>
