express req.session在另一条路线中是空的

Question

有什么建议吗？ Express req.session在另一条路线中是空的。

可以按以下路线打印：

console.log(user) req.session.userid = user.userid req.session.username = user.username c onsole.log('sesesese') console.log(req.session) console.log(req.session.userid) console.log('Is matched!') res.send({status: 1,userid: req.session.userid}) console.log(req.session) console.log(req.session.userid)

Session {
  cookie: 
   { path: '/',
     _expires: null,
     originalMaxAge: null,
     httpOnly: true } }

但是当我使用另一条路线时，req.session是空的：

router.get('/logStatus',function(req, res) { console.log(req.session.cookie) console.log(req.session.username) if (req.session) { res.send( {userid: req.session.userid,username: req.session.username} ) } else { res.send({status: 0}) }})

app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(cookieParser())
app.use(session({
  secret: 'sessionsecret',
  resave: false,
  saveUninitialized: true,
  cookie:{ path: '/', httpOnly: true, secure: false, maxAge: null }
}))
app.use('/',index)
app.use('/admin',admin)
app.use('/test',test)

这是我的app.js：

//get system albums
PHImageRequestOptions * options = [[PHImageRequestOptions alloc] init];
options.networkAccessAllowed = YES;
options.synchronous = YES;
KVPhotoAlbum * userAlum = nil;
PHCachingImageManager * manager = [[PHCachingImageManager alloc] init];
PHFetchResult * systemAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeSmartAlbum subtype:PHAssetCollectionSubtypeAlbumRegular options:nil];
for (id object in systemAlbums) {
    if ([object isKindOfClass:[PHAssetCollection class]]) {
        PHAssetCollection * collection = (PHAssetCollection*)object;
        if (collection.assetCollectionSubtype == PHAssetCollectionSubtypeSmartAlbumVideos) {
            continue;   
        }
        //get photo
        PHFetchResult * imageResults = [PHAsset fetchAssetsInAssetCollection:collection options:nil];
        if (imageResults.count) {
            KVPhotoAlbum * album = [[KVPhotoAlbum alloc] init];
            album.collection = collection;
            album.title = [collection valueForKey:@"localizedTitle"];
            album.photoCount = imageResults.count;
            if (collection.assetCollectionSubtype == PHAssetCollectionSubtypeSmartAlbumUserLibrary) {
                //camera
                userAlum = album;
            }else {
                [_albums addObject:album];
            }
            PHAsset * asset = [imageResults lastObject];
            [manager requestImageForAsset:asset targetSize:CGSizeMake(60, 60) contentMode:PHImageContentModeDefault options:options resultHandler:^(UIImage * _Nullable result, NSDictionary * _Nullable info) {
                album.image = result;
            }];
        }
    }
}
//get albums created by user
PHFetchResult * customAlbums = [PHCollectionList fetchTopLevelUserCollectionsWithOptions:nil];
for (id object in customAlbums) {
    if ([object isKindOfClass:[PHAssetCollection class]]) {
        PHAssetCollection * collection = (PHAssetCollection*)object;
        if (collection.assetCollectionSubtype == PHAssetCollectionSubtypeSmartAlbumVideos) {
            continue;   
        }
        //get photo
        PHFetchResult * imageResults = [PHAsset fetchAssetsInAssetCollection:collection options:nil];
        if (imageResults.count) {
            KVPhotoAlbum * album = [[KVPhotoAlbum alloc] init];
            album.collection = collection;
            album.title = [collection valueForKey:@"localizedTitle"];
            album.photoCount = imageResults.count;
            [_albums addObject:album];
            PHAsset * asset = [imageResults lastObject];
            [manager requestImageForAsset:asset targetSize:CGSizeMake(60, 60) contentMode:PHImageContentModeDefault options:options resultHandler:^(UIImage * _Nullable result, NSDictionary * _Nullable info) {
                album.image = result;
            }];
        }
    }
}

我已将它存储在mongoDB中，我使用react和fetch，当我获取时，mongo会话存储将添加会话，它们是否隐藏了原始会话？
