How can I disable the HTML view in Drupal 8? - drupal

So I'm building a website with Drupal as its backend and an Angular frontend. I'm creating all kinds of content-types in Drupal and then I'm exposing those the content through a JSON view (or in other words a RESTful API). However, Drupal also still exposes an HTML view for all content. I wish to disable that, because it is of no use to me and I don't want it to be accidentally found and maybe even indexed.
Is there an easy way to disable the HTML view for all content?

hook_entity_view and from there block access or change render could be one solution

Have your webserver deny based on the content type sent. I believe nginx has $sent_http_content_type for this purpose.
Alternatively, write an event subscriber subscribing to KernelEvents::RESPONSE and if the response is not a ResourceResponseInterface then throw an AccessDeniedHttpException.

firebase storage custom html page for errors like permission denied?

Is there a way to show a custom html page or redirect a user when storage throws errors like if file is not available, not sufficient permissions or in case of any other issues when the file can't be accessed/displayed?
So instead of the below
We need to show a custom page with our brand designs.
What are the options here?
No, there is not. You are using an API endpoint (download URL) meant for programmatic consumption or inline page insertion, not for loading into a browser to present a full web page.

Adding simple CMS functionality to an existing MVC application

ASP.NET 4.51, MVC 5
Have read Integrating a CMS into an established application-centric MVC website
We have a number of MVC applications that serve as public facing websites. The applications were built using MVC as that was the technology stack understood by the developers and primarily the content that was being delivered was based on business process data.
However more and more we are being asked to add "another page" to the websites which for all intents and purposes is a plain old static content page. This ultimately involves:
Adding a new route
Creating a view with the required HTML
We have various "home grown" solutions which now pull HTML from the database for these views. However this means we are writing custom back end data entry screens as well as 1 & 2 above.
So.... There must be a better way. Has anyone got any practical experience or suggestions on how to add simple CMS functionality that we can give to end users, plugged into our MVC application? We need to provide the following functionality to the end user:
Create new pages, edit pages using WYSIWYG
Add meta tags and canonical tags for SEO
Specify the url portion of the uri for SEO purposes
All insights appreciated.
Is it feasible to do the following:
Have a database table to house the content for these pages. e.g. title, summary, description, url, meta, image(s) etc...
In the front end have a template for these pages. The database data fills in the placeholders within this template.
Perhaps hold all the pages on a base URL like www.yoursite.com/page/dynamic-page-url-from-db
You can use the Remote attribute validation on the url field to make sure they are all unique in the database.
With this in mind, create a single Route to catch the requests and filter valid/invalid requests in the Page controller based on the URL provided with the db. If non-existent throw new HttpException(404, "Page Not Found"); and have an error handler pick that up and deliver your 404.
META could be set via ViewBag or a dedicated section that alters the _Layout file at the point of rendering the view.
TinyMCE is a decent WYSIWYG editor. You can even add dynamic image gallery functionality to it if you want to embed images within the main body of the pages.
I'm working on making a CMS currently used in a demanding production environment into a product. I've just (as of 20 Jan 2015) made a NuGet package which installs the CMS into an MVC project which should be possible to add to any existing MVC site without breaking it. CMS functionality can then be added where needed. Currently I'm looking to work with some users to help them get the CMS into production on their sites, however this may have changed by the time you read this. Look at http://www.lynicon.com for more information and to sign up to a Slack community where I can give you access to the NuGet package.

Drupal: How to share content between two Drupal sites?

I have two drupal 7 sites and I want them to share content of a certain content type. I want to have this content stored in an external database. How could I make this happen with a custom module?
You can setup a Rest server.
Then you can use views to share the information you want.
Module: https://drupal.org/project/services
Maybe have a closer look on these modules:
Drupal Sync
Drupal Deploy
I didn't try out one of these so far, but I think it's what you are looking for.
Contents (ie. nodes) on a Drupal site are not stored in a single tables. The same tables are used to store content of different content type. Some of the tables are created dynamically when you add fields to a content type, or when you change their settings. So you cannot share some contents between two sites by simply sharing the table(s) used to store them.
As a rule of thumb, you cannot achieve anything complexe in Drupal by simply doing stuff at the database level. There is too much storage logic implemented in (PHP) code that cannot be ignored when accessing the DB. You should always base your solution on Drupal's API (and most of the time, not the DB layer API, but the high-level API such as the Node and Fields APIs).
That said, there is no core API to communicate between sites. I would use one of the site as the canonical source of the shared contents and the only site where they can be edited. Then somehow replicate these content on the second site. This can be done with the Services or RESTful Web Services module on the second site, and a custom module on the first site, used to push new contents and the updated contents to the second through a REST service.

Legitamate cross site communication

I am building a website, within a large intranet, that wraps and adds functionality to another site within the same intranet. I do not have access to the other site's source and they do not provide any api's for the functionality they provide. I need to, somehow, have my server-side code go to that site, fill in some forms, then press a submit button.
Is this possible? If so, how can I accomplish this?
Note: I am working in asp.NET if that matters at all.
Not the most efficient, but maybe WatiN can get you started:
http://watin.sourceforge.net/
Just look at the URL the form is supposed to submit to and the method it employs (POST or GET) and then send a request to that URL using the same method and put the field you want as parameters
Your server-side code is basically a web client to the other web site. You will need to write the code to send the HTML form data to the other web site and process the response. I would start with the System.Net.WebClient class. Take a look at System.Net.WebClient.UploadValues. That class/method will enable you to POST the form data to the web site via a NameValueCollection.

Updateable Google Sitemap for ASP.NET 3.5 Web App Project

I am working on an ASP.NET 3.5 Web Application project in C#. I have manually added a Google-friendly sitemap which includes entries for every page in the project - this is not a CMS.
<url>
<loc>http://www.mysite.com/events.aspx</loc>
<lastmod>2009-11-17T20:45:46Z</lastmod>
<changefreq>daily</changefreq>
<priority>0.8</priority>
</url>
The client updates events using an admin back-end. Other than that, the site is relatively static. I'm trying to decide on the best way to update the <lastmod> values for a handful of pages that are regularly updated.
In particular, I am using the QueryStringField of the ListView control to enhance SEO as described here:
https://web.archive.org/web/20211029044137/https://www.4guysfromrolla.com/articles/010610-1.aspx
http://gsej.wordpress.com/2009/05/31/using-a-datapager-with-both-a-querystringfield-and-renderdisabledbuttonsaslabels/
When the QueryStringField property is set, the DataPager renders the paging interface as a series of hyperlinks which the crawler can follow and index. However, if Google has crawled my list of events two days ago, and in the meantime, the admin has added another dozen events... say the page size is set to 6; in this case, the Google SERP links would now be pointing to the wrong pages. This is why I need to be sure that the sitemap reflects changes to the events page as soon as they happen.
I have already looked though other SO questions for info and didn't find what I needed. Can anyone offer some guidance or an alternative approach?
UPDATE:
Since this is a shared hosting environment, a directory watcher/service won't work:
How to create file watcher in shared webhosting environment
UPDATE:
Starting to realize that I may need signify to Google that the containing page has been updated; update the last-modified HTTP header?
Rather than using a hand-coded sitemap, create a sitemap handler that will generate the sitemap on the fly. You can create a method in the handler that will grab pages from an existing navigation sitemap, from the database, or even from a hard-coded list of pages. You can create an XmlDocument from the list, and write the InnerXml of the document out to the handler response stream.
Then, create a class with a method that will automatically ping search engines with the above handler's URL (like http://www.google.com/webmasters/tools/ping?sitemap=http://www.mysite.com/sitemap.ashx).
Whever someone adds a new event, call the above method. This will ping Google using your latest sitemap (freshly generated by the above method).
You want to make sure that the ping only works if the sitemap has actually been updated. You could use File.SetLastWriteTime on events.aspx in the AddNewEvent handler to signify that the containing page has been updated.
Aslo, be careful to make sure there have been no pings for the last hour (as Google guidelines discourage pinging more than once per hour).
I actually plan to implement this in the following OSS project: http://cyclemania.codeplex.com. I will let you know once it's done and you can have a look.
If you let your user add events to the website you are probably using a database.
This means you can generate the XML-Sitemap at runtime like this:
create a page where your sitemap will be available (this doesn't need to be sitemap.xml but can also be sitemap.aspx or even sitemap.ashx).
open a database connection
loop through all records and create an Xml Element for each record
This blog post should help you further: Build a Search Engine SiteMap in C#.
It is not using the new XElements from .Net 3.5, but is will work fine.
You can put this in an aspx page, but adding an HttpHandler is probably better as described on the same blog, different post: (creating a httphandler for a sitemap)
