Question

我正在使用Graham Campbell的markdown parser作为Laravel在我正在建造的应用程序中。虽然它确实将Markdown解析为HTML，但它实际上是返回标签，而不是我正在寻找的格式化文本。以下是有问题的观点：

import java.awt.Color;
import java.awt.Dimension;
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.GridLayout;
import java.awt.Label;
import java.awt.Panel;
import java.awt.RenderingHints;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class TestClass extends Panel {


        /**
         * 
         */
        private static final long serialVersionUID = 1L;

        Panel ballPanel = new Panel();
        Label ballLabel = new Label();
        Panel coordinatePanel = new Panel();
        Label coordinateLabel = new Label();
        int nowX, nowY;
        Label nowXcoordinateLabel = new Label("Now X :");
        Label nowYcoordinateLabel = new Label("Now Y :");

        TestClass() {

            coordinatePanel.add(coordinateLabel);
            nowXcoordinateLabel.setBackground(Color.WHITE);
            nowYcoordinateLabel.setBackground(Color.WHITE);
            nowXcoordinateLabel.setPreferredSize(new Dimension(100, 25));
            nowYcoordinateLabel.setPreferredSize(new Dimension(100, 25));
            coordinatePanel.setPreferredSize(new Dimension(400, 30));
            coordinatePanel.setBackground(Color.LIGHT_GRAY);
            coordinatePanel.add(nowXcoordinateLabel);
            coordinatePanel.add(nowYcoordinateLabel);

            MouseAdapter ml = new MouseAdapter() {

                @Override
                public void mouseMoved(MouseEvent e) {
                    nowXcoordinateLabel.setText("Now X :" + e.getX());
                    nowYcoordinateLabel.setText("Now Y :" + e.getY());
                    nowX = e.getX();
                    nowY = e.getY();
                    repaint();
                    super.mouseMoved(e);
                }

            };


            setLayout(new GridLayout(1, 1));
            setBackground(Color.WHITE);
            addMouseMotionListener(ml);
            setVisible(true);
            setSize(400, 400);
        }


        @Override
        public void paint(Graphics g) {
            Graphics2D gg = (Graphics2D) g;
            gg.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
            gg.setColor(Color.BLUE);
            gg.fillOval(nowX, nowY, 20, 20);

        }

        public static void main(String[] arg) {
            TestClass mb = new TestClass();
            Frame frame = new Frame("Test drawing");
            frame.addWindowListener(new WindowAdapter() {


                @Override
                public void windowClosing(WindowEvent e) {
                     frame.dispose();
                    super.windowClosing(e);
                }


            });
            frame.setLayout(new GridLayout(1, 1));
            frame.add(mb);
            frame.add(mb.coordinatePanel);
            frame.setSize(800, 600);
            frame.setVisible(true);
        }


}

我最初的怀疑是str_limit方法与它有关，但改变操作的顺序甚至完全删除str_limit都没有效果。因此，例如，目前，如果我的帖子有正文@extends('layouts.app') @section('stylesheet') <link rel="stylesheet" href="{{ asset('css/writing.css') }}"> @endsection @php use GrahamCampbell\Markdown\Facades\Markdown; @endphp @section('content') <h2 class="writing_title">writing</h2> <h4 class="writing_subtitle">musings & guides</h4> <hr class="divider"> <section class="writing_listing"> @foreach( $posts as $post ) <article class="writing_article"> <div class="writing_article-title_block"> <h3 class="writing_article-title">{{ $post->title }}</h3> <span class="writing_article-datetime">{{ date('M j, Y H:i', strtotime($post->created_at)) }}</span> </div> <div class="writing_article-content_block"> {{ str_limit(Markdown::convertToHtml($post->body), 250) }} </div> <a href="{{ url('writing/'.$post->slug) }}">Read More</a> </article> @endforeach </section> @endsection，那么我将取回的字面意思是# Header of post字符串而不是帖子。我的所有段落都以<h1>Header of post</h1>作为字符串限定。

问题最有可能出现在这里：

{{ str_limit(Markdown::convertToHtml($post->body), 250) }}

laravel中的双括号（{{ }}）将被清理，这将使您的代码作为实际标记而不是格式化输出。你能做的就是替换它：

{{ str_limit(Markdown::convertToHtml($post->body), 250) }}

用这个：

{!! str_limit(Markdown::convertToHtml($post->body), 250) !!}

此语法将未经过验证的html回显到您的模板中。

希望这有帮助！欢呼声。
