前端js-put上传函数分享

export const fileCOSUpload = (files) => {
  return new Promise(async (resolve, reject) => {
    const { data, status  } = await axios.post(`xxxx`,  {
        RequestId: keyGuid(),
        DataType: 2,
        UserName: Cookie.get('ti-user'),
        FileName:files.name});
    // 获取到 Url 后，前端可以这样 ajax 上传
    let xhr = new XMLHttpRequest();
    // put上传
    xhr.open('PUT', data.Response.UploadAddress, true);
　　// 请求头
    xhr.setRequestHeader('X-TC-Titoken', Cookie.get('ti-token'));
    xhr.onload = (e) => {
      resolve(data.Response.FileId);
    };
    xhr.onerror = (e) => {
      reject(null);
    };
    xhr.send(files); // files 是要上传的文件对象
  })
};
