@app.route('/tiji', methods=['POST']) def tiji(): dch = request.form.get('dch') name = request.form.get('filename') print(name) folder_name = f"{dch}dianyun" if not os.path.exists(folder_name): os.mkdir(folder_name) for file in request.files.getlist('file'): filename = file.filename file.save(os.path.join(folder_name, filename)) dhs = request.form.getlist('dh') print(len(dhs)) for i in range(len(dhs)): print(dhs[i]) folder_path = os.path.join(folder_name) file_name = f"{name}.laz" if has_file(folder_path, file_name): return jsonify({"code": 200, "msg": "success"}) else: return jsonify({"code": 500, "msg": "fail"}) print('hi') 用什么替换return jsonify，可以在发送success给前端后还可以打印hi

如果你想在发送成功响应给前端后打印 "hi"，你可以使用 `print()` 函数并在最后使用 `return` 语句返回一个字符串给前端。这样可以同时在控制台打印消息并发送响应。

以下是修改后的代码示例：

@app.route('/tiji', methods=['POST'])
def tiji():
    dch = request.form.get('dch')
    name = request.form.get('filename')
    print(name)
    folder_name = f"{dch}dianyun"

    if not os.path.exists(folder_name):
        os.mkdir(folder_name)
    for file in request.files.getlist('file'):
        filename = file.filename
        file.save(os.path.join(folder_name, filename))

    dhs = request.form.getlist('dh')
    print(len(dhs))
    for i in range(len(dhs)):
        print(dhs[i])

    folder_path = os.path.join(folder_name)
    file_name = f"{name}.laz"

    if has_file(folder_path, file_name):
        print('hi')  # 在此处打印 "hi"
        return "success"  # 返回一个字符串给前端
    else:
        return "fail"  # 返回一个字符串给前端

在上面的代码中，我将 `return jsonify()` 替换为了 `return "success"` 和 `return "fail"`，这样就可以返回一个字符串给前端。同时，我在成功情况下添加了一个 `print('hi')` 语句，用来打印 "hi"。
