MIME type: application/json
It is used when it is not known how this data will be used. When the information is to be just extracted from the server in JSON format, it may be through a link or from any file, in that case, it is used. In this, the client side only gets the data in JSON format that can be used as a link to data and can be formatted in real-time by any front-end framework.
Example: In this example, the MIME-type is application/json as it is just extracting the dictionary from that variable and putting it in JSON format, and showing it.
<?php
// Setting the header
header('Content-Type:application/json');
// Initializing the directory
$dir =[
['Id'=> 1, 'Name' => 'Geeks' ],
['Id'=> 2, 'Name' => 'for'],
['Id'=> 3, 'Name' => 'Geeks'],
];
// Shows the json data
echo json_encode($dir);
?>
Output:
[{"Id":1, "Name":"Geeks"}, {"Id":2, "Name":"for"}, {"Id":3, "Name":"Geeks"}]
What is the correct JSON content type ?
The correct JSON content type specifies the format of data transmitted over the web as JSON. It ensures proper interpretation by client and server applications, enabling seamless communication and interoperability between systems exchanging JSON-formatted data.
The Content-Type HTTP header specifies the media type of a resource or response, aiding browsers in interpreting returned content. MIME sniffing, based on Multipurpose Internet Mail Extension (MIME), determines content types. Setting the MIME type for JSON requests ensures proper interpretation, enhancing data exchange between client and server.
So we set its MIME type by mentioning it in the Content-Type. We can do the same in two ways:
- MIME type: application/json
- MIME type: application/javascript
