句法:base64.b64encode(s[, altchars]) 参数:该函数以s作为输入,它是必需的参数。 返回值:b64encode() 函数返回编码后的字符串。 Python中Image转base64的例子 import base64 with open("..//pythonProject3/python_download_logo.png", "rb") as img_file: b64_string = base64.b64encode(img_file.re...
The only difference is that in Python 3 the Base64 output is a b string. from PIL import Image from io import BytesIO import base64 # Convert Image to Base64 def im_2_b64(image): buff = BytesIO() image.save(buff, format="JPEG") img_str = base64.b64encode(buff.getvalue()) ret...
This honestly should be all that you need: https://docs.python.org/3.1/library/base64.html In this example you can see where they convert bytes to base64 and decode it back to bytes again: >>> import base64 >>> encoded = base64.b64encode(b'data to be encoded') >>> encoded b'...
the required base64 encoding for an image 600 bytes long would be 800 bytes, so if an HTTP request required more than 200 bytes of overhead, the data URI would be more efficient.
.NET中,可以使用 Convert.ToBase64String(FileUpload1.FileBytes) 方法把上传的图片文件转换成 Base64 格式的字符串。 在Java 中,引入 ws-commons-util-1.0.2.jar 包,或者 org.python.apache.xerces.impl.dv.util.Base64.decode(youtData)( jython.jar) 包 使用下面的方法可以进行还原 ...
Similarly, the b64decode() function takes the base64 encoded string, converts it into a byte string, and returns the decoded byte string. For this particular problem, we’ll have to first convert our input string into a byte string with the bytes.fromhex() function. We’ll then encode ...
