添加了响应头信息后，正常访问时是有响应头，错误访问403、404等请求的响应头是没有的

如下在server里添加头信息：

        add_header X-Content-Type-Options nosniff;
        add_header 'Referrer-Policy' 'origin';
        add_header X-Download-Options "noopen" always;
        add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";
        add_header X-Permitted-Cross-Domain-Policies  "master-only";
        add_header X-Frame-Options SAMEORIGIN;
        add_header Content-Security-Policy "default-src 'self' data: *.xxx.com  'unsafe-inline' 'unsafe-eval' mediastream: ";
        add_header X-Content-Type-Options: nosniff;
        add_header X-XSS-Protection "1; mode=block";

正常访问时响应头里面就有这些信息：

strict-transport-security:

max-age=63072000; includeSubdomains; preload

x-content-type-options:

nosniff

x-content-type-options:

: nosniff

x-content-type-options:

nosniff

x-download-options:

noopen

x-frame-options:

SAMEORIGIN

x-frame-options:

: sameorigin

x-permitted-cross-domain-policies:

master-only

访问403、404时，响应头里就没有这些信息，如何在错误访问时也在响应头添加这些信息？
