FLASK 修改Server响应标头

原来的响应标头：

Connection:close

Content-Length:6427

Content-Type:text/html; charset=utf-8

Date:Tue, 14 Mar 2023 03:03:42 GMT

Server:Werkzeug/2.2.2 Python/3.10.7

Vary:Cookie

我想隐藏Server标头，可以通过覆盖 Flask.process_response() 方法来更改每个响应的服务器标头。如下所示（验证通过）：

SERVER_NAME = 'lichun'
class localFlask(Flask):
    def process_response(self, response):
        # Every response will be processed here first
        response.headers['server'] = SERVER_NAME
        return (response)
app = localFlask(__name__)

同理也应该可以修改其他headers的内容。如下所示：

class localFlask(Flask):
    def process_response(self, response):
        # Every response will be processed here first
        response.headers['Access-Control-Allow-Origin'] = '*'       
        response.headers['Access-Control-Allow-Headers'] ='*'
        return (response)
