使用python生成一个图片验证码，随机的，可以由于验证人机和别的啊，很方便很简单
导入模块
import random from PIL import Image,ImageFont,ImageDraw
生成随机验证码
def rndtxt():
txt_list = []
# 大写字母
txt_list.extend([i for i in range(65,90)])
# 小写字母
txt_list.extend([i for i in range(97,123)])
# 数字
txt_list.extend([i for i in range(48,57)])
return chr(txt_list[random.randint(0,len(txt_list)-1)])
作为待会生成的图片背景色和字体色
def rndbgcolor():
# 背景颜色
return (random.randint(64,255),random.randint(64,255),random.randint(64,255))
def rndtxtcolor2():
# 字体颜色
return (random.randint(32,127),random.randint(32,127),random.randint(32,127))
进行生成打印验证码并以图片的形式打开，不保存图片文件，仅用于一时的验证码验证
def code():
weight = 240
hight = 60
image = Image.new('RGB',(weight,hight),(255,255,255))
font = ImageFont.truetype('msyh.ttc',36)
draw = ImageDraw.Draw(image)
# 填充背景颜色
for x in range(weight):
for y in range(hight):
draw.point((x,y),fill=rndbgcolor())
# 生成随机验证码
for T in range(4):
rndtxt_2 = rndtxt()
print(rndtxt_2) # 打印验证码的值
draw.text((60 * T + 10,10),rndtxt_2,font=font,fill=rndtxtcolor2())
image.show()
完整代码：
#!/usr/bin/env python3
import random
from PIL import Image,ImageFont,ImageDraw
def rndtxt():
txt_list = []
# 大写字母
txt_list.extend([i for i in range(65,90)])
# 小写字母
txt_list.extend([i for i in range(97,123)])
# 数字
txt_list.extend([i for i in range(48,57)])
return chr(txt_list[random.randint(0,len(txt_list)-1)])
def rndbgcolor():
# 背景颜色
return (random.randint(64,255),random.randint(64,255),random.randint(64,255))
def rndtxtcolor2():
# 字体颜色
return (random.randint(32,127),random.randint(32,127),random.randint(32,127))
def code():
weight = 240
hight = 60
image = Image.new('RGB',(weight,hight),(255,255,255))
font = ImageFont.truetype('msyh.ttc',36)
draw = ImageDraw.Draw(image)
# 填充背景颜色
for x in range(weight):
for y in range(hight):
draw.point((x,y),fill=rndbgcolor())
# 生成随机验证码
for T in range(4):
rndtxt_2 = rndtxt()
print(rndtxt_2) # 打印验证码的值
draw.text((60 * T + 10,10),rndtxt_2,font=font,fill=rndtxtcolor2())
image.show()
code()
