Base64,简单地讲,就是用 64 个字符来表示二进制数据的方法。这 64 个字符包含小写字母 a-z、大写字母 A-Z、数字 0-9 以及符号"+"、"/",其实还有一个 "=" 作为后缀用途,所以实际上有 65 个字符。
Python 内置了一个用于 Base64 编解码的库:base64
:
base64.b64encode()
解码使用 base64.b64decode()
import base64def convert_image(): # Picture ==> base64 encode with open('d://FileTest//Hope_Despair.jpg', 'rb') as fin: image_data = fin.read() base64_data = base64.b64encode(image_data) fout = open('d://FileTest//base64_content.txt', 'w') fout.write(base64_data.decode()) fout.close() # base64 encode ==> Picture with open('d://FileTest//base64_content.txt', 'r') as fin: base64_data = fin.read() ori_image_data = base64.b64decode(base64_data) fout = open('d://FileTest//Hope_Despair_2.jpg', 'wb') fout.write(ori_image_data) fout.close() if __name__ == '__main__': convert_image()对图片进行 Base64 编码和解码(Pythonic)
import base64def convert_image(): # Picture ==> base64 encode with open('d://FileTest//Hope_Despair.jpg', 'rb') as fin, open('d://FileTest//base64_content.txt', 'w') as fout: fout.write(base64.b64encode(fin.read()).decode()) # base64 encode ==> Picture with open('d://FileTest//base64_content.txt', 'r') as fin, open('d://FileTest//Hope_Despair_2.jpg', 'wb') as fout: fout.write(base64.b64decode(fin.read())) if __name__ == '__main__': convert_image()
