在我的 apache 错误日志中，我保存了一堆 ssl 警告You configured HTTPS(443) on the standard HTTP(80) port!

这是我的site.ca.conf文件

<VirtualHost *:80>
  ServerName site.ca:80
  DocumentRoot "/var/www/site/public"
  <Directory "/var/www/site/public">
    AllowOverride all
  </Directory>
RewriteEngine on
RewriteCond %{SERVER_NAME} =site.ca
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

这是我的site.ca-le-ssl.conf

<IfModule mod_ssl.c>
<VirtualHost *:443>
  ServerName site.ca:80
  DocumentRoot "/var/www/site/public"
  <Directory "/var/www/site/public">
    AllowOverride all
  </Directory>
ServerAlias site.ca
SSLCertificateFile /etc/letsencrypt/live/site.ca/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/site.ca/privkey.pem
Include /etc/letsencrypt/options-ssl-apache.conf
</VirtualHost>
</IfModule>

每件事都运转良好。我不知道为什么这个警告每天都会出现在我的 apache 日志文件中，我该如何解决它？

我想获得READ_EXTERNAL_STORAGE权限.这是我的代码

    // Check if user granted the permission
    int hasReadExternalStoragePermission = ContextCompat.checkSelfPermission(this,
            Manifest.permission.READ_EXTERNAL_STORAGE);


   if(hasReadExternalStoragePermission == PackageManager.PERMISSION_GRANTED) {
       displaySongs();
   } else {
       // Should we show explanation?
        if( ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.READ_EXTERNAL_STORAGE)) {
               // Show explanation to user
        } else {

            // No explanation needed. We can request permissions
            String permissions[] = {
                    Manifest.permission.READ_EXTERNAL_STORAGE
            };
            ActivityCompat.requestPermissions(this, permissions, REQUEST_PERMISSIONS_CODE);
        }
   }

这是回叫方法

    @Override
public void onRequestPermissionsResult(int requestCode,  String[] permissions, int[] grantResults) {

    switch (requestCode) {
        case REQUEST_PERMISSIONS_CODE:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // Permission Granted …
