A typical use case occurs when a web user submits a web form on a web page that uses CGI. The form's data is sent to the web server within an HTTP request with a URL denoting a CGI script. The web server then launches the CGI script in a new computer process, passing the form data to it.
Copy the URL of that link, paste it into a text editor, and read (or copy) the QID from it. For example for Kofoworola Abeni Pratt, that URL is d:Q25796287, and so the QID is Q25796287. Alternatively, click on the "Wikidata item" link to visit the item directly, and read the QID from the top of that page (or its URL).
A query string is a part of a uniform resource locator (URL) that assigns values to specified parameters. A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.
As part of a GET request, some data can be passed within the URL's query string, specifying (for example) search terms, date ranges, or other information that defines the query. As part of a POST request, an arbitrary amount of data of any type can be sent to the server in the body of the request message.
curl is a command-line tool for getting or sending data including files using URL syntax. curl provides an interface to the libcurl library; it supports every protocol libcurl supports. [14] curl supports HTTPS and performs SSL certificate verification by default when a secure protocol is specified such as HTTPS.
Visiting the above URL in a web browser will initiate a GET request, calling the API and showing the user a result, known as a return value or as a return. This API returns JSON , a type of data format intended to be understood by computers, but which is somewhat easy for a human to read as well.
