从在线图片中提取文本 Url In python

Question

我已经根据网络上的参考资料和一些 youtube 视频编写了代码，但它似乎对我不起作用，我也无法进一步理解可能是什么问题。

import io
import requests
import pytesseract
from PIL import Image

r = requests.get("http://www.teamjimmyjoe.com/wp-content/uploads/2014/09/Classic-Best-Funny-Text-Messages-earthquake-titties.jpg",stream=True)
# print( type(response) ) # <class 'requests.models.Response'>

img = Image.open(io.BytesIO(r.content))
# print( type(img) ) # <class 'PIL.JpegImagePlugin.JpegImageFile'>
text = pytesseract.image_to_string(img)

print(text)

我收到这个错误

  File "F:\Projects\FileExtractor\untitled3.py", line 16, in <module>
    img = Image.open(io.BytesIO(r.content))

  File "C:\ProgramData\Anaconda3\lib\site-packages\PIL\Image.py", line 2943, in open
    raise UnidentifiedImageError(

UnidentifiedImageError: cannot identify image file <_io.BytesIO object at 0x000001E85C0BAA40>

请帮我解决这个问题。谢谢

Answer 1

始终从最简单的修复开始，然后从那里开始。

import requests
# import pytesseract
# from PIL import Image

r = requests.get("http://www.teamjimmyjoe.com/wp-content/uploads/2014/09/Classic-Best-Funny-Text-Messages-earthquake-titties.jpg",stream=True)

print(r.text)

产生这个结果：

<head><title>Not Acceptable!</title></head><body><h1>Not Acceptable!</h1><p>An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.</p></body></html>

问题是您没有下载图像，您被 Mod_Security 阻止了。在获得图像和文本之前，您需要克服这一点。

想了想。为什么不欺骗浏览器 headers，这现在似乎可以工作了。

import io
import requests
import pytesseract
from PIL import Image

url = 'http://www.teamjimmyjoe.com/wp-content/uploads/2014/09/Classic-Best-Funny-Text-Messages-earthquake-titties.jpg'
headers = {'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.95 Safari/537.36'}

r = requests.get(url, headers=headers)

img = Image.open(io.BytesIO(r.content))
# # print( type(img) ) # <class 'PIL.JpegImagePlugin.JpegImageFile'>
text = pytesseract.image_to_string(img)
#
print(text)

响应是：
