话不多说,直接干货走起:
看到了吗?字体加密了。那就找。。定位到加密字体的地方,然后看右边的styles,你是不是看到了与字体相关的名字—font-family,就是他,复制他然后源码里面全局搜索,你会看到如下东西:
woff?就是这个字体文件。正则拿下来,接下来是正题
# 获取源码里面的字体加密源码 base_str = re.findall(r"base64,(.*?))",response.text)[0]
将base64编码的字体字符串解码成为二进制格式,写成.woff文件,再通过BytesIO把一个二进制内存块当成一个文件来操作
def make_font_file(base64_string: str): #将base64编码的字体字符串解码成为二进制格式 bin_data = base64.decodebytes(base64_string.encode()) with open(‘testotf.woff‘,‘wb‘) as f: f.write(bin_data) return bin_data def convert_font_to_xml(bin_data): #BytesIO把一个二进制内存块当成一个文件来操作 font = TTFont(BytesIO(bin_data)) #将解码字体保存为xml font.saveXML(‘test1.xml‘)
再用画笔把他画出来,顺便使用pytesseract库把他识别出来
def draw(path): #接下来就是画字体了 #创建一张空的画板,大小为80*30,默认填充为白色 im = Image.new(‘RGB‘,(90,30),(255,255,255)) #获取绘制的上下文环境(绘制的起始地址) dr = ImageDraw.Draw(im) #创建要绘制的字体 font = ImageFont.truetype(BytesIO(make_font_file(base_str)),18) #开始绘制(10,5)是起始绘制坐标,fill指明字体的填充色为黑色 dr.text((10,5),text,font=font,fill="#000000") im.save(‘hh.jpg‘) result = pytesseract.image_to_string(path).replace(‘ ‘,‘.‘) return result
这样就可以得到解码后的数字了。。
不过毕竟识别肯定不是百分之百能成功的。另外还有一种可以完全实现,但是他的对应关系还没找到,搞了一半,半成品(我发现这个可以https://www.jianshu.com/p/5aa978e9823d)不过又验证了一下,发现他的字体库是在变化的,所以说这个好像不可以用了。

这一块的对应关系不对,所以这个暂时可以不用!!

我知道你还缺少pytesseract 库,https://digi.bib.uni-mannheim.de/tesseract/直接下载吧,记得下载完,修改一下pytesseract.py这个文件下的tesseract_cmd,这个后面跟你的路径
