Evaluate website with the Facebook Sharing Debugger

30.04.2018 (👁7319)

Evaluate website with the Facebook Sharing Debugger

 

The Facebook debugger can be found below

with https://developers.facebook.com/tools/debug/sharing

Here you can enter in the input field the URL of your own website, which one wants to share and where to get an error, or pictures as thumbnails are not passed.

 

Enter a URL in Facebook Debugger

If I then enter the URL in the Facebook sharing debugger,

Test the page, even before sharing with link to Facebook

[Lnk "https://developers.facebook.com/tools/debug/sharing/?q=https%3A%2F%2Freaddy.net%2FNotes%2FDetails%2F124" /]

then comes

[Lnk "https://readdy.net/Notes/Details/124" /]

This URL has not yet been shared on Facebook.

Conclusion: you must have shared the page once.

 

If you enter a page that has already been shared with Facebook,

then comes a detailed evaluation

 

Warnings that should be fixed

·        Derived property

The og: image property should be explicitly specified, even if a value can be derived from other tags.

·        Specification of excess properties

The following properties have been specified on the website. They are NOT supported for the specified og: type property: og: title, og: type, og: url, og: image, og: site_name, og: description

·        Missing properties

The following required properties are missing: og: url, og: type, og: title, og: image, og: description, fb: app_id

 

 

 

<meta property="og: title" content="

👁🗨 Test Fehler: Account/ExternalLoginCallback#_=_" />

<meta property="og: type" content="website" />

<meta property="og: url" content="https://Readdy.net/Notes/Details/124 " />

<meta property="og: image" content="https://Readdy.net/User_Files/Notes/Images/Image_124_0_blog.jpg" />

<meta property="og: site_name" content="Readdy.Net" />

<meta property="og: description" content=" Test Das kommt wenn man sich versucht über Facebook einzuloggen https readdy net Account ExternalLoginCallback ">

 

 

Under Visual Studio in the source code of the controller you will find the error

 

            //--< MetaData >--

            int lenMax200 = note.Text.Length;

            if (lenMax200 > 200) lenMax200 = 200;

            string sMetaDescription = note.Text.Substring(0, lenMax200);

            String sMetaData = "<meta property=\"og: title\" content=\"👁🗨 " + note.Title + "\" />";

            sMetaData += Environment.NewLine + "<meta property=\"og: type\" content=\"website\" />";

            sMetaData += Environment.NewLine + "<meta property=\"og: url\" content=\"https://Readdy.net/Notes/Details/" + note.IDNote + " \" />";

            sMetaData += Environment.NewLine + "<meta property=\"og: image\" content=\"https://Readdy.net/User_Files/Notes/Images/Image_" + note.IDNote + "_0_blog.jpg\" />";

            sMetaData += Environment.NewLine + "<meta property=\"og: site_name\" content=\"Readdy.Net\" />";

            sMetaData += Environment.NewLine + "<meta property=\"og: description\" content=\"" + sMetaDescription + "\">";

            sMetaData += Environment.NewLine + "";

 

            ViewData["MetaData"] = sMetaData;

            //--</ MetaData >--

 

            //< out to view >

            string sMobile_Extenstion = Request_Methods.set_optional_Mobile_Extension(Request);

            return View("details" + sMobile_Extenstion, data);

            //</ out to view >

 

 

Solution:

The meta tag must be generated WITHOUT spaces

"<meta property=\"og: image\"
