当图片转换为base64编码字符串后，其中包含大量的+号，如果我们将上述base64编码字符串通过网络传输给其他接口，那么服务器在解析数据时会把+号当成连接符，然后自动将+号转换为空格，所以为保证数据的准确性，我们需要将空格转换成+号，转换方法如下：
import base64 def encode_to_base64(text): encoded_bytes = base64.b64encode(text.encode('ascii')) encoded_str = encoded_bytes.decode('ascii') return encoded_str def decode_from_base64(encoded_str): decoded_bytes = base64.b64decode(encoded_str.encode('ascii')) decoded_str = decoded_byte...

base64_encode():将文本编码为Base64格式。Base64是一种将二进制数据转换为可打印ASCII字符的编码方式。它将文本转换为一串由大小写字母、数字和特殊字符组成的字符序列。 base64_decode():将经过Base64编码的文本解码为原始文本。 这些函数在处理文本编码和解码时非常有用,特别是在处理URL参数、加密数据传输等场景中...
