js向request添加参数

function addParamsToUrl(url, params) {
    const queryString = Object.keys(params)
        .map(key => `${encodeURIComponent(key)}=${encodeURIComponent(params[key])}`)
        .join('&');
    return `${url}?${queryString}`;
}

// 使用示例
const url = 'https://example.com/api';
const params = { key1: 'value1', key2: 'value2' };
const fullUrl = addParamsToUrl(url, params);

// 发送GET请求
fetch(fullUrl)
    .then(response => response.json())
    .then(data => console.log(data))
    .catch(error => console.error('Error:', error));

function sendPostRequest(url, data) {
    return fetch(url, {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json'
        },
        body: JSON.stringify(data)
    })
    .then(response => response.json())
    .catch(error => console.error('Error:', error));
}

// 使用示例
const url = 'https://example.com/api';
const data = { key1: 'value1', key2: 'value2' };

sendPostRequest(url, data)
    .then(responseData => console.log(responseData))
    .catch(error => console.error('Error:', error));

const formData = new FormData();
formData.append('key1', 'value1');
formData.append('key2', 'value2');

fetch(url, {
    method: 'POST',
    body: formData
})
.then(response => response.json())
.catch(error => console.error('Error:', error));
