Once we have done so, we define a function,get_base64_encoded_image, that takes an image path as the parameter. When we have the image path, we use theopenfunction to get a file object to the image that we wish to encode in Base64. If we can do so successfully, then we usebase...
或者你可以说你的 base64 编码字符串在一对单引号中。要从 Python 中的 base64 代码前缀中删除b’,可以使用string.encode(‘utf-8’)方法。 推荐:使用Python截取屏幕截图的3种方法 import base64 with open("..//pythonProject3/python_download_logo.png", "rb") as img_file: b64_string = base64.b64...

目前,我将编码的base64存储在一个长文本字段中,该字段的字符集为“utf8mb4”。当我尝试从数据库中将代码向下拉并将其加载到图像中时,无法打开得到的图像。我做错什么了?这是我用来编码图像文件的代码。 def convertImageToJSON(): # pick an image file you have in the working directory # or give full ...
