我使用Blueimp/jquery-file-upload插件直接从JS客户端代码将文件上传到AWS S3。我用过multipart上传。这是fileupload的设置:
multipart: true,
maxChunkSize: 10 * 1024 * 1024,
autoUpload: true,
当我使用此事件侦听器记录响应时:'fileuploadchunkdone'
我可以看到所有块都已上传,但在存储桶中只保存了最后一个块。另外,当我在上传过程中看到我的存储桶时,我可以看到文件大小相等的块大小,但是在上传完整文件大小等于最后一个块大小后,文件已损坏。
我做错了什么吗?或者这是一些错误?
这是我的S3设置:
CORS:
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
<CORSRule>
<AllowedOrigin>*</AllowedOrigin>
<AllowedMethod>GET</AllowedMethod>

</CORSConfiguration>
感谢您的帮助!

这是我用于此的js代码:
$('.upload-video-part').each(function(){
var that = this;
var videoId;
$(this).fileupload({
sequentialUploads: true,
multipart: true,
disableValidation: true,
maxChunkSize: 10 * 1024 * 1024,
autoUpload: true,
add: function (event, data) {
$(that).find('input[type=file]').hide();
$(that).find('#progress').show();
$.ajax({
url: "/uploaded_videos",
type: 'POST',
dataType: 'json',
data: {doc: {title: data.files[0].name}},
async: false,
success: function(retdata) {
$(that).find('input[name=key]').val(retdata.key);
$(that).find('input[name=policy]').val(retdata.policy);
$(that).find('input[name=signature]').val(retdata.signature);
$(that).parent().append('<div id="video-edit-form-' + retdata.id + '"></div>');
videoId = retdata.id;
data.submit();
$.get({
url: "/edit_after_upload?id=" + videoId,
success: function(data) {
$('#edit_uploaded_video_' + retdata.id).submit(function(e, data){
e.preventDefault();
var messageArea = $('#edit_uploaded_video_' + retdata.id).find('.message-area')[0];
$.ajax({
type: 'PUT',
url: $('#edit_uploaded_video_' + retdata.id).attr('action'),
data: $('#edit_uploaded_video_' + retdata.id).serialize(),
success: function(data) {
$(messageArea).css('color', 'rgba(0, 255, 0, .5');
messageArea.innerHTML = 'Video was successfuly saved!';
$(messageArea).css('display', 'inline-block');
},
error: function(err){
$(messageArea).css('color', 'rgba(255, 0, 0, .5');
messageArea.innerHTML = err.responseJSON.errors;
$(messageArea).css('display', 'inline-block');
}
});
return false;
});
}
});
}
});
},
send: function(e, data) {},
fail: function(e, data) {
$(that).find('.fileinput-button span')[0].innerHTML = 'Video uploading failed';
$(that).find('#progress .bar').css('background', 'red');
},
done: function (event, data) {
$(that).find('.fileinput-button span')[0].innerHTML = 'Video successfully uploaded';
$(that).find('#progress .bar').css('background', 'green');
},
progressall: function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$(that).find('#progress .bar').css( 'width', progress + '%');
}
}).on('fileuploadchunksend', function (e, data) {});
});

在 s3 中以多个块上传文件。首先使用s3 api创建Multi Part Upload。
https://docs.aws.amazon.com/AmazonS3/latest/API/API_CreateMultipartUpload.html
您将从此 API 收到上传 ID。
然后使用这个api上传parts,在数据中提供partNumber和upload id。
https://docs.aws.amazon.com/AmazonS3/latest/API/API_UploadPart.html#API_UploadPart_RequestSyntax
使用etag和partNumber从这个api接收,通过API_CompleteMultipartUpload完成partUpload
https://docs.aws.amazon.com/AmazonS3/latest/API/API_CompleteMultipartUpload.html
