When I click on "GET DATA" in my App, I would like to access the data in my IBM Cloud with an HTTP request. I need the data in JSON format. This should be implemented with JavaScript. My current code is here:
function httpRequest() {
const xhr = new XMLHttpRequest()
//open a get request with the remote server URL
xhr.open("GET", "https://<orgID>.internetofthings.ibmcloud.com/api/v0002/device/types/<typeID>/devices/<deviceID>/state/<logicalInterfaceID>" )
//send the Http request
xhr.send()
//EVENT HANDLERS
//triggered when the response is completed
xhr.onload = function() {
if (xhr.status === 200) {
//parse JSON datax`x
data = JSON.parse(xhr.responseText)
console.log(data.count)
console.log(data.products)
} else if (xhr.status === 404) {
console.log("No records found")
}
}
//triggered when a network-level error occurs with the request
xhr.onerror = function() {
console.log("Network error occurred")
}
//triggered periodically as the client receives data
//used to monitor the progress of the request
xhr.onprogress = function(e) {
if (e.lengthComputable) {
console.log(`${e.loaded} B of ${e.total} B loaded!`)
} else {
console.log(`${e.loaded} B loaded!`)
}
}
}.btn {
cursor: pointer;
background-color: #555;
color: #fff;
display: inline-block;
padding: 5px;
margin-left: auto;
margin-right: auto;

The problem is, I don't know how to include the username and password in the URL so that I can access the IBM Cloud.

You can base64 encode your credentials using the native btoa() function then set them in the authorization req header.
var xhr = new XMLHttpRequest();
xhr.open( "GET", "https://<orgID>...");
xhr.setRequestHeader("Authorization", `Basic ${btoa('username:password')}`);
xhr.send();
