我尝试使用python v3.8.0在Flask应用程序上导入dll失败！我收到以下错误：

/.../pythonproject/MyDLL.dll: unknown file type, first eight bytes: 0x4D 0x5A 0x50 0x00 0x02 0x00 0x00 0x00
这是我的代码：
from flask import Flask, jsonify
from ctypes import *
import os.path
app = Flask(__name__)
@app.route('/')
def hello_world():
dll_file = os.path.join(os.path.dirname(os.path.abspath(__file__)), "MyDLL.dll")
print(dll_file)
libc = cdll.LoadLibrary(dll_file)
# libc = CDLL(dll_file)
return jsonify(username= 'whatever',
email='whatever',
id='whatever')
我需要从该库导入并使用方法。 你能帮我吗？
谢谢！
