简单搞定生成验证码：
1.views.py
from io import BytesIO import random from PIL import Image,ImageDraw,ImageFont from utils.check_code import create_validate_code def checkCode(request): return render(request,'code_test.html') def codetest(request): # # 获取随机颜色的函数 # def get_random_color(): # return random.randint(0, 255), random.randint(0, 255), random.randint(0, 255) # # # 生成一个图片对象 # img_obj = Image.new( # 'RGB', # (220, 35), # get_random_color() # ) # # 在生成的图片上写字符 # # 生成一个图片画笔对象 # draw_obj = ImageDraw.Draw(img_obj) # # 加载字体文件， 得到一个字体对象 # font_obj = ImageFont.truetype('arial.ttf', 28) # # 开始生成随机字符串并且写到图片上 # tmp_list = [] # for i in range(5): # u = chr(random.randint(65, 90)) # 生成大写字母 # l = chr(random.randint(97, 122)) # 生成小写字母 # n = str(random.randint(0, 9)) # 生成数字，注意要转换成字符串类型 # # tmp = random.choice([u, l, n]) # tmp_list.append(tmp) # draw_obj.text((20 + 40 * i, 0), tmp, fill=get_random_color(), font=font_obj) # # # 保存到session # request.session["valid_code"] = "".join(tmp_list) # # 加干扰线 # width = 220 # 图片宽度（防止越界） # height = 35 # for i in range(5): # x1 = random.randint(0, width) # x2 = random.randint(0, width) # y1 = random.randint(0, height) # y2 = random.randint(0, height) # draw_obj.line((x1, y1, x2, y2), fill=get_random_color()) # # # 加干扰点 # for i in range(40): # draw_obj.point((random.randint(0, width), random.randint(0, height)), fill=get_random_color()) # x = random.randint(0, width) # y = random.randint(0, height) # draw_obj.arc((x, y, x + 4, y + 4), 0, 90, fill=get_random_color()) # # # 不需要在硬盘上保存文件，直接在内存中加载就可以 # io_obj = BytesIO() # # 将生成的图片数据保存在io对象中 # img_obj.save(io_obj, "png") # # 从io对象里面取上一步保存的数据 # data = io_obj.getvalue() # return HttpResponse(data)
2.url
urlpatterns = [ path('admin/', admin.site.urls), url('^checkcode.html$',views.checkCode), url('^codetest.html',views.codetest), ]
