js中的ajax传两个参数

var xhr = new XMLHttpRequest();
xhr.open('POST', 'your-endpoint-url', true);
xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');

var param1 = 'value1';
var param2 = 'value2';
var params = 'param1=' + encodeURIComponent(param1) + '&param2=' + encodeURIComponent(param2);

xhr.onreadystatechange = function() {
    if (xhr.readyState === 4 && xhr.status === 200) {
        console.log(xhr.responseText);
    }
};

xhr.send(params);

var param1 = 'value1';
var param2 = 'value2';
var params = new URLSearchParams({ param1: param1, param2: param2 });

fetch('your-endpoint-url', {
    method: 'POST',
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded'
    },
    body: params
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error('Error:', error));
