我正在尝试上传大文件(~2 GB)。我从Express中删除了bodyParser,以阻止服务器崩溃在大文件上。崩溃错误也是间歇性的,因此我甚至无法在错误发生时选择,以及原因。
代码如下:
channel = req.params.channel
models.channel.findOne name: channel, (err, show) ->
if err then console.log err
if show?
form = formidable.IncomingForm()
files = []
fields = []
form.uploadDir = __dirname + '/../public/videos/resources/'
form.on 'field', (field, value) ->
#console.log field + ' ' + value
fields.push [field,value]
form.on 'file', (field, file) ->
#console.log file
files.push [field, file]
form.on 'end', ->
for file in files
filename = file[1].name.replace /(.*)\//, ''
ext = file[1].name.replace /(.*)\./, ''
filename = uuid("#{filename}" + Date.now()) + ".#{ext}"
fs.renameSync file[1].path, form.uploadDir + filename
v = new models.video
v.channel_id = channel._id
v.title = 'Episode'
v.description = ''
v.url = filename
v.save (err,results) ->
if err then console.log err
res.send 200
form.parse req
else
res.send 403
有时上传会起作用,有时它会弹出以下内容:
Error: parser error, 0 of 65536 bytes parsed

是否有其他人遇到过这个问题,或者知道是什么导致了这个问题?
答案 0 :(得分:0)
我遇到了类似的错误,问题是由我的中间件中对数据库的异步调用引起的。在设置请求数据事件的任何处理程序之前发送了异步调用。这导致强大的数据丢失。

data.getCategories (err, results) ->
res.locals.categories = results
next()

data.getCategories = (callback) ->
pg.connect connString, (err, client) ->
client.query "SELECT name, slug FROM categories", (err, result) ->
callback err, result.rows
