文件是一个文本文件，里面的base64编码的图片

import base64
import os

input_file = "D:\\rainbow\\Downloads\\1.txt"
output_file = os.path.join(os.path.dirname(input_file), "output.jpg")

try:
  with open(input_file, "r") as file:
    base64_data = file.read().strip()
  if base64_data.startswith("data:image/jpg;base64,"):
    base64_data = base64_data.split(",")[1]
  binary_data = base64.b64decode(base64_data)
  with open(output_file, "wb") as image_file:
    image_file.write(binary_data)
  print(f"图片已成功保存为 {output_file}")
except FileNotFoundError:
