const uploadFile = function uploadFile(client) {
if (!uploadFileClient || Object.keys(uploadFileClient).length === 0) {
uploadFileClient = client;
}


const file = document.getElementById('file').files[0];
const key = document.getElementById('object-key-file').value.trim() || 'object';


console.log(`${file.name} => ${key}`);
const options = {
progress,
partSize: 500 * 1024,
timeout:60000,
meta: {
year: 2017,
people: 'test',
},
callback: {


//此处是添加上传回调的位置。
url: 'https://example.aliyundoc.com/v2/sync',
/* host: 'oss-cn-shenzhen.aliyuncs.com', */
/* eslint no-template-curly-in-string: [0] */
body: 'bucket=${bucket}&object=${object}&var1=${x:var1}',
contentType: 'application/x-www-form-urlencoded',
customValue: {
var1: 'value1',
var2: 'value2',
},
},
