Question

开始使用symfony并遇到服务问题。

... \应用\配置\ services.yml

app.pdf.service:
    class: AppBundle\Service\PdfService
    arguments: [format, orientation]]

... \ SRC \的appbundle \服务\ PdfService.php

namespace AppBundle\Service;

class PdfService
{

    private $format;
    private $orientation;

    public function __construct($format, $orientation)
    {
        $this->format = $format;
        $this->orientation = $orientation;
    }

}

现在我尝试使用以下服务：

$this->container->get('app.pdf.service');

我忘记了什么吗？ $ this-＆gt; container-＆gt; get（ist working，因为我从whiteoctober / tcpdf-bundle调用了tcpdf / Service。我将扩展此服务，因为我需要更多的功能。

任何提示？ cu s00n n00n

假设您的参数中定义了格式和方向，请尝试：

Description

＆＃34;硬编码＆＃34;定义示例：

'use strict'

import _ from 'moar-lodash'
import Promise from 'bluebird'
import Mongoose from 'mongoose'
import Async from 'async'
import Util from 'util'
import * as appRoot from 'app-root-path'

Mongoose.Promise = Promise

Mongoose.connect( appRoot.require('./dist/lib/config').database.connection )

const accountLib = appRoot.require('./dist/lib/account')

const models = require( '../models' )( Mongoose )

models.Asset.getAsset( '56d0819b655baf4a4a7f9cad' )
    .then( assetDoc => {
        var jqDoc = JSON.parse(JSON.stringify(assetDoc.toJSON()))

        // Show the CURRENT description
        console.log('[IN QUERY - Before Modify]\n\t', jqDoc.attributes[1].value)

        assetDoc.attr('Description').set( 'Date-'+Date.now() )

        return assetDoc.save()

    } )
    .then(data => {
        // Just show the Description AFTER it was saved
        console.log('[AFTER QUERY - AFTER Modify]\n\t', data.attributes[1].value)
    })
    .catch( err => console.error( 'ERROR:',err ) )
    .finally( () => {
        Mongoose.connection.close()
        console.log('# Connection Closed')
    })


[IN QUERY - Before Modify]
     Date-1474915946697
[MIDDLEWARE ORIGINAL Desc]
     Date-1474916372134
[MIDDLEWARE NEW Desc]
     Date-1474916372134
[AFTER QUERY - AFTER Modify]
     Date-1474916372134
# Connection Closed
