我在服务器端使用jquery-file-upload和Python-Flask。每当我上传一个大的100mb +文件时,上传的版本比原来的略大,并且不会打开(已损坏)。我已经为10mb块的大文件启用了分块,我试图将“disableImageResize”设置为“true”以及尝试单个和多个文件,结果是一样的。我在代码中遗漏了什么吗?
main.js
$(function () {
'use strict';
// Initialize the jQuery File Upload widget:
$('#fileupload').fileupload({
// Uncomment the following to send cross-domain cookies:
//xhrFields: {withCredentials: true},
url: 'rs_upload',
disableImageResize: true,
sequentialUploads: true,
// redirect: 'home',
done: function (e, data) {
console.log("uploaded: " + data.files[0].name)
}
, maxChunkSize: 10000000, // 10 MB,
}).bind('fileuploadstop', function (e, data) {
if (data.loaded == data.total){window.location.replace("rs_create")}
});
views.py
@app.route("/rs_upload", methods=["GET", "POST"])
def rs_upload():
if request.method == 'POST':
files = request.files['file']
fs = files
handle_file(fs)
fullpath = session.get('finalpath')
if 'Content-Range' in request.headers:
# extract starting byte from Content-Range header string
range_str = request.headers['Content-Range']
start_bytes = int(range_str.split(' ')[1].split('-')[0])
# append chunk to the file on disk, or create new
with open(fullpath, 'a') as f:
f.seek(start_bytes)
f.write(fs.stream.read())
else:
# this is not a chunked request, so just save the whole file
fs.save(fullpath)
return jsonify({"name": fs.filename,
"size": os.path.getsize(fullpath),
"url": 'uploads/' + fs.filename,
"thumbnail_url": None,
"delete_url": None,
"delete_type": None,})
return render_template('remote_sensing/upload.html')

不确定这是否是问题,但会尝试
with open(fullpath, 'ab') as f:
打开&以二进制模式附加到文件。
