安卓js怎么参数传递到后台

let param1 = "value1";
let param2 = "value2";
let url = "https://your-backend-api.com/endpoint?param1=" + param1 + "&param2=" + param2;
fetch(url)
    .then(response => response.json())
    .then(data => console.log(data))
    .catch(error => console.error(error));

let data = {
    param1: "value1",
    param2: "value2"
};
fetch("https://your-backend-api.com/endpoint", {
    method: "POST",
    headers: {
        "Content-Type": "application/json"
    },
    body: JSON.stringify(data)
})
.then(response => response.json())
.then(data => console.log(data))
.catch(error => console.error(error));

<form action="https://your-backend-api.com/endpoint" method="POST">
    <input type="text" name="param1" value="value1">
    <input type="text" name="param2" value="value2">
    <button type="submit">提交</button>
</form>
