First, you need to create an APP on facebook. For the creation method, see https://developers. facebook.com/, the APP has an item to fill in the Domain, fill in the Domain of your website here. (The APP is bound to the domain and cannot be filled in randomly)
Then you can use facebook comments plugins.
Using facebook comments plugins, facebook comments can be inserted into the page.
Generate code method: https://developers.facebook.com/docs/plugins/comments
For example: There is a page called http://www.example.com/. Insert the following code into this page to use comments plugings.
<!-- include facebook js sdk --> <script id="facebook-jssdk" src="//connect.facebook.net/en_GB/all.js#xfbml=1&appId=这里填写APPID"></script> <!-- comments plugins --> <fb:comments colorscheme="light" numposts="4" height="360px;" width="614px" href="http://www.example.com/" fb-xfbml-state="rendered" class="fb_iframe_widget"></fb:comments>
