Teknik Request POST dan GET

METHOD XMLHttpRequest()

Request POST

var xhr = new XMLHttpRequest();
xhr.open('POST', '/', true);
xhr.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
xhr.send(JSON.stringify({
    "data": ""
}));
xhr.onload = function () {
    if (xhr.readyState == 4 && xhr.status == 200) {
        console.log(xhr.responseText);
    };
};

Request GET

var xhr = new XMLHttpRequest();
xhr.open('GET', '/', true);
xhr.onload = function () {
    if (xhr.readyState == 4 && xhr.status == 200) {
        console.log(xhr.responseText);
    };
};
xhr.send();

METHOD fetch()

Fetch POST

fetch('/', {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json',
        },
        body: JSON.stringify({
            "data": ""
        }),
})
.then(response => response.text())
.then(data => {
    console.log(data);
})
.catch((error) => {
   console.error(error);
});

Fetch GET

Jika respon adalah dalam bentuk JSON

fetch('/')
.then(response => response.json())
.then(function (data) {
   console.log(data)
});

 

Jika respon dalam bentuk teks

fetch('/')
.then(response => response.text())
.then(function (data) {
   console.log(data)
});
