使用 aliyun-oss-sdk-4.4.4.min.js

方式一 客户端授权

https://help.aliyun.com/document_detail/32069.html

通过 new OSS.Wapper() 来创建client， OSS.Wrapper 提供了异步的接口，类似于callback的方式，在 .then() 中处理返回的结果，在 .catch() 中处理错误。

注意这里暴露了accessKeySecret，实际应用中在客户端不可采用这种方式。

<body>

<script src="http://gosspublic.alicdn.com/aliyun-oss-sdk-4.4.4.min.js"></script>

  <input type="file" id="file" />

  <script type="text/javascript">

    var client = new OSS.Wrapper({

      region: '<oss region>',

      accessKeyId: '<Your accessKeyId>',

      accessKeySecret: '<Your accessKeySecret>',

      bucket: '<Your bucket name>'

    });

    document.getElementById('file').addEventListener('change', function (e) {

      var file = e.target.files[0];

      var storeAs = 'upload-file';

      console.log(file.name + ' => ' + storeAs);

      client.multipartUpload(storeAs, file).then(function (result) {

        console.log(result);

      }).catch(function (err) {

        console.log(err);

      });

    });

  </script>

</body>

方式二 采用服务端授权

https://github.com/rockuw/oss-in-browser

<script>
var appServer = 'http://localhost:3000';//STS授权服务端

var bucket = 'js-sdk-bucket-sts';

var region = 'oss-cn-hangzhou';

var urllib = OSS.urllib;

var OSS = OSS.Wrapper;

var STS = OSS.STS;

var applyTokenDo = function (func) {

  var url = appServer;

  return urllib.request(url, {

    method: 'GET'

  }).then(function (result) {

    var creds = JSON.parse(result.data);

    var client = new OSS({

      region: region,

      accessKeyId: creds.AccessKeyId,

      accessKeySecret: creds.AccessKeySecret,

      stsToken: creds.SecurityToken,

      bucket: bucket

    });

    return func(client);

  });

};

var progress = function (p) {

  return function (done) {

    var bar = document.getElementById('progress-bar');

    bar.style.width = Math.floor(p * 100) + '%';

    bar.innerHTML = Math.floor(p * 100) + '%';

    done();

  }

};

var uploadFile = function (client) {

  var file = document.getElementById('file').files[0];

  var key = document.getElementById('object-key-file').value.trim() || 'object';

  console.log(file.name + ' => ' + key);

  return client.multipartUpload(key, file, {

    progress: progress

  }).then(function (res) {

    console.log('upload success: %j', res);

    return listFiles(client);

  });

};

window.onload = function () {

  document.getElementById('file-button').onclick = function () {

    applyTokenDo(uploadFile);

  }

};
</script>
