Question

我正在编写一个Python脚本，我想要批量上传照片。我想读取一个Image并将其转换为字节数组。任何建议都将不胜感激。

#!/usr/bin/python
import xmlrpclib
import SOAPpy, getpass, datetime
import urllib, cStringIO
from PIL import Image
from urllib import urlopen 
import os
import io
from array import array
""" create a proxy object with methods that can be used to invoke
    corresponding RPC calls on the remote server """
soapy = SOAPpy.WSDL.Proxy('localhost:8090/rpc/soap-axis/confluenceservice-v2?wsdl') 
auth = soapy.login('admin', 'Cs$corp@123')

Answer 1

使用bytearray：

with open("img.png", "rb") as image:
  f = image.read()
  b = bytearray(f)
  print b[0]

您还可以查看struct，可以进行多次转换。

Answer 2

我不知道转换为字节数组，但很容易将其转换为字符串：

import base64

with open("t.png", "rb") as imageFile:
    str = base64.b64encode(imageFile.read())
    print str

Answer 3

with BytesIO() as output:
    from PIL import Image
    with Image.open(filename) as img:
        img.convert('RGB').save(output, 'BMP')                
    data = output.getvalue()[14:]

我只是用它来将图像添加到Windows中的剪贴板。

Answer 4

这对我有用

# Convert image to bytes
import PIL.Image as Image
pil_im = Image.fromarray(image)
b = io.BytesIO()
pil_im.save(b, 'jpeg')
im_bytes = b.getvalue()
return im_bytes

用于将Image转换为Byte数组的Python脚本
