[英]SailsJS action2 multiple file upload
我正在嘗試從sailsjs 1.2.4 上傳多個文件
這是我的行動:
module.exports = {
friendlyName: 'Post',
description: 'Post something.',
files: ['mediaFiles'],
inputs: {
text : {
required: true,
type: 'string',
},
mediaFiles : {
description : "Media files",
example: '===',
required : false
}
},
exits: {
},
fn: async function (inputs) {
inputs.mediaFiles._files.forEach(file=>{
console.log(file)
})
})
}
}
我在文件 object 中得到以下結果:
{ stream:
PassThrough {
_readableState:
ReadableState {
objectMode: false,
highWaterMark: 16384,
buffer: BufferList { head: [Object], tail: [Object], length: 2 },
length: 43093,
pipes: null,
pipesCount: 0,
flowing: null,
ended: true,
endEmitted: false,
reading: false,
sync: false,
needReadable: false,
emittedReadable: true,
readableListening: false,
resumeScheduled: false,
emitClose: true,
destroyed: false,
defaultEncoding: 'utf8',
awaitDrain: 0,
readingMore: false,
decoder: null,
encoding: null },
readable: true,
domain: null,
_events:
{ prefinish: [Function: prefinish],
drain: [Function],
end: [Function],
error: [Array] },
_eventsCount: 4,
_maxListeners: undefined,
_writableState:
WritableState {
objectMode: false,
highWaterMark: 16384,
finalCalled: false,
needDrain: false,
ending: true,
ended: true,
finished: true,
destroyed: false,
decodeStrings: true,
defaultEncoding: 'utf8',
length: 0,
writing: false,
corked: 0,
sync: false,
bufferProcessing: false,
onwrite: [Function: bound onwrite],
writecb: null,
writelen: 0,
bufferedRequest: null,
lastBufferedRequest: null,
pendingcb: 0,
prefinished: true,
errorEmitted: false,
emitClose: true,
bufferedRequestCount: 0,
corkedRequestsFree: [Object] },
writable: false,
allowHalfOpen: true,
_transformState:
{ afterTransform: [Function: bound afterTransform],
needTransform: false,
transforming: false,
writecb: null,
writechunk: null,
writeencoding: 'buffer' },
headers:
{ 'content-disposition':
'form-data; name="mediaFiles"; filename="bwDzrPkA_400x400.jpg"',
'content-type': 'image/jpeg' },
name: 'mediaFiles',
filename: 'bwDzrPkA_400x400.jpg',
byteOffset: 378,
byteCount: 43093,
field: 'mediaFiles' },
status: 'bufferingOrWriting' }
我的問題是如何將此文件 stream 寫入 /public/media/xyz.png 之類的路徑。 我曾經使用帆正常文件上傳,我可以使用 this.req.file("name").upload().. 但不是在行動 2。我檢查了其他答案,但他們上傳到 s3 而不是在同一台服務器上寫入。
您可以使用依賴 Sails sails-hook-uploads
,因為您可以在設置中定義dirpath
:
https://github.com/sailshq/sails-hook-uploads/blob/master/index.js#L31
module.exports.upload = {
dirpath: '.tmp/public', // recommended .tmp/uploads
adapter: require('skipper-disk'), // Default
}
我強烈建議不要使用公用文件夾,因為它是已編譯的資產目的地,因此您可能會丟失這些文件。
作為替代方案,您可以使用 controller 上傳文件,如下所示:
https://github.com/mikermcneil/ration/blob/master/api/controllers/things/upload-thing.js#L54
之后,將其發送給用戶:
https://github.com/mikermcneil/ration/blob/master/api/controllers/things/download-photo.js#L50
