Browser Usage

Use the putObjectFromBlob api.

browserify -s baidubce-sdk index.js -o baidubce-sdk.bundle.js

var sdk = require('./baidubce-sdk.bundle');
var $ = require('jquery');

$('files').on('change', function (evt) {
    var file = evt.target.files[0];

    var client = new sdk.BosClient(getBOSConfig());
    var bucket = getBucket();
    var key = file.name;
    var blob = file;

    var ext = key.split(/\./g).pop();
    var mimeType = sdk.MimeType.guess(ext);
    if (/^text\//.test(mimeType)) {
        mimeType += '; charset=UTF-8';
    }
    var options = {
        'Content-Type': mimeType
    };
    var promise = client.putObjectFromBlob(bucket, key, blob, options);
    client._httpAgent._req.xhr.upload.onprogress = function (evt) {
        if (evt.lengthComputable) {
            $('#g_progress').val(evt.loaded / evt.total);
        }
    };
    promise.then(function (res) {
        $('#g_progress').val(1);
        var url = client.generatePresignedUrl(bucket, key)
        $('#g_url').html('<a href="' + url + '" target="_blank">下载地址</a>');
    })
    .catch(function (err) {
        console.error(err);
    });
});
