回送组件存储错误：请求中止

Question

我正在尝试配置将环回文件上传到Firebase存储。主要问题是我使用的是半年前可用的代码。

代码停止工作，出现以下错误：

error: Error: Request aborted

我已经阅读了所有stackoverflow，但情况有所不同。我不使用multer和bodyParser。只是尝试以与以前相同的方式上载vie Ajax文件。

这是我的datasource.js配置：

"storage": {
  "name": "storage",
  "connector": "loopback-component-storage",
  "provider": "google",
  "keyFilename": "config/firebase-key.json",
  "projectId": "spoc",

}

images.js

/**

    const uploadHandler = (err, fileObj, cb, req) => {
        console.log(fileObj);
        if(err) cb(err);
        else {
            const files = fileObj.files['files'];
            const imageData = files.map(file => {
                return {
                    name: file.name,
                    type: file.type,
                    container: file.container,

                };
            });
            Images.create(imageData, (err, obj) => createImageHandler(err, obj, cb));
        }
    };

    /**
     * Create image metadata entry.
     * @param {Object} err - create image metadata error object.

    const createImageHandler = (err,obj, cb) => {
        if (err !== null) cb(err);
        else cb(null, obj);
    };

    /** Configuration object for upload method */
    const remoteMethodConfig = {
        description: 'Uploads a file',
        accepts: [
            {arg: 'req', type: 'object', 'http': {source: 'req'}},
            {arg: 'res', type: 'object', 'http': {source: 'res'}}, 
            { arg: 'options', type: 'object', http:{ source: 'query'} }
        ],
        returns: {
            arg: 'fileObject', type: 'object', root: true
        },
        http: {verb: 'post'}
    };

    /** Get current project id to define approrpiate firebase storage bucket.  */
    const projectId = firebase.instanceId().app.options.projectId;

    /** Upload image to Firebase storage bucket. */
    Images.upload = (req, res, options, cb) => {
        console.log(projectId);
        console.log(req.body);
        if(!options) options = {};
        req.params.container = `${projectId}`;
        // ctx.req.data = ctx.req.body;
        Images.app.models.container.upload(req, res, options, (err, fileObject) => {
            uploadHandler(err, fileObject, cb, req)
        });
    };

    Images.remoteMethod('upload', remoteMethodConfig);
};

因此，请求挂起，然后中止。核心问题是它在六月某个地方工作：（
