Question

在创建要添加到MongoDB的新对象时，我的要求之一是使用multer将图像文件上传到服务器。映像已成功上传到本地存储库，并生成了文件路径。我正在尝试通过Pictures数组将生成的文件路径保存到mongodb，但是无法发布文件路径数组。

我已经用谷歌搜索了这个问题，但是找不到解决方法。

当前正在运行带有multer 1.4.1的Angular 5，Mongo db v3.6.3。我正在使用Node.js作为我的服务器。

这是架构：

var FiguredataSchema = new mongoose.Schema({
    name: {type: String, required: true},
    releasedate: {type: Date, required: true},
    announcedate: {type: Date},
    brand: {type: String, required: true},
    series: {type: String, required: true},
    number: {type: Number},
    manufacturer: {type: String},
    distributor: {type: String},
    releaseprice: {type: Number},
    currencytype: {type: String, default: "USD"},
    notes: {type: String},
    pictures: {type: Array},
    thumbnail: {type: String}
},{timestamps: true});

这是POST路径：

app.post('/add', upload.array("uploads[]",10), function(request, response){ //ADD FIGURE TO DB
    var dict = request.files;
    var name = request.body.name;
    var releasedate = request.body.releasedate;
    var announcedate = request.body.announcedate;
    var brand = request.body.brand;
    var series = request.body.series;
    var number = request.body.number;
    var manufacturer = request.body.manufacturer;
    var distributor = request.body.distributor;
    var releaseprice = request.body.releaseprice;
    var currencytype = request.body.currencytype;
    var notes = request.body.notes;

    if(request.files == null){
        console.log("errortype", request)
    }
    else{
        console.log("else")
        var newfigure = new Figuredata(
            {
            name: name,
            releasedate: releasedate,
            announcedate: announcedate,
            brand: brand,
            series: series,
            number: number,
            manufacturer: manufacturer,
            distributor: distributor,
            releaseprice: releaseprice,
            currencytype: currencytype,
            notes: notes,
            pictures: []
            }
        )
        for(var i = 0; i < dict.length; i++){
            for(var key in dict[i]){
                if(key == "path"){
                    newfigure.pictures.push(dict[i][key]); 

                }
            }
        }
        console.log("log",newfigure.pictures)
        newfigure.save(function(error){
            if(error){
                response.json({message: "Error", error: error});
            }
            else{
                response.json({message: "success!", data: newfigure});
            }
        });
    }})

预期结果是看到具有以下结果的对象（对不起，我正在测试它的愚蠢日期）：

{
"_id" : ObjectId("5c319fdb41c91e0663c2d008"),
"currencytype" : "JPY",
    "pictures" :[
"images/pictures/43958469.2_4589642701118_primary.jpg",
"images/pictures/1543613133070.jpg","images/pictures/1545875011468.jpg"],
    "name" : "1212121",
    "releasedate" : ISODate("2019-12-12T00:00:00.000Z"),
    "announcedate" : ISODate("2018-12-12T00:00:00.000Z"),
    "brand" : "adfasdf",
    "series" : "asdfasd",
    "number" : 1212121212,
    "manufacturer" : "waefasdf",
    "distributor" : "efsdfsdf1",
    "releaseprice" : 1000,
    "notes" : "sdfasdfasdfsadf",
    "createdAt" : ISODate("2019-01-06T06:27:39.703Z"),
    "updatedAt" : ISODate("2019-01-06T06:27:39.703Z"),
    "__v" : 0
}

但是，当POST路径被命中时，它不保存而是命中response.json（{message：“ Error”，error：error}）;图像确实保存到了预期的区域，但是文件路径和整个mongo对象没有保存，从而发送错误。
