Request.json()
The json()
method of the Request
interface
reads the request body and returns it as a promise that resolves with the result of parsing the body text as JSON
.
Note that despite the method being named json()
, the result is not JSON but is instead the result of taking JSON as input and parsing it to produce a JavaScript object.
Syntax
request.json().then(data => {
// do something with your data
});
Parameters
None.
Return value
A Promise
that resolves to a JavaScript object. This object could be
anything that can be represented by JSON — an object, an array, a string, a number...
Examples
const obj = {hello: 'world'};
const request = new Request('/myEndpoint', {
method: 'POST',
body: JSON.stringify(obj)
});
request.json().then(function(data) {
// do something with the data sent in the request
});
