vue进阶——整合富文本编辑器wangEditor

前言

个人整合wangEditor过程中的经验与总结

一、什么是wangEditor？

wangEditor是一款基于JavaScript的富文本编辑器插件，用于在网页中实现所见即所得的编辑功能。它提供了丰富的编辑功能，包括文字样式设置、插入图片、插入表格、代码高亮等。wangEditor易于集成和使用，支持自定义配置和扩展。

二、安装wangEditor

1. React

yarn add @wangeditor/editor-for-react
# 或者 npm install @wangeditor/editor-for-react --save

2. Vue2

yarn add @wangeditor/editor-for-vue
# 或者 npm install @wangeditor/editor-for-vue --save

3. Vue3

yarn add @wangeditor/editor-for-vue@next
# 或者 npm install @wangeditor/editor-for-vue@next --save

4. CDN

<!-- 引入 css -->
<link href="https://unpkg.com/@wangeditor/editor@latest/dist/css/style.css" rel="stylesheet">

<!-- 引入 js -->
<script src="https://unpkg.com/@wangeditor/editor@latest/dist/index.js"></script>
<script>
    var E = window.wangEditor; // 全局变量
</script>

三、基本使用

1. vue2

<template>
    <div style="border: 1px solid #ccc;">
        <Toolbar
            style="border-bottom: 1px solid #ccc"
            :editor="editor"
            :defaultConfig="toolbarConfig"
            :mode="mode"
        />
        <Editor
            style="height: 500px; overflow-y: hidden;"
            v-model="html"
            :defaultConfig="editorConfig"
            :mode="mode"
            @onCreated="onCreated"
        />
    </div>
</template>
<script>
import Vue from 'vue'
import { Editor, Toolbar } from '@wangeditor/editor-for-vue'

export default Vue.extend({
    components: { Editor, Toolbar },
    data() {
        return {
            editor: null,
            html: '<p>hello</p>',
            toolbarConfig: { },
            editorConfig: { placeholder: '请输入内容...' },
            mode: 'default', // or 'simple'
        }
    },
    methods: {
        onCreated(editor) {
            this.editor = Object.seal(editor) // 一定要用 Object.seal() ，否则会报错
        },
    },
    mounted() {
        // 模拟 ajax 请求，异步渲染编辑器
        setTimeout(() => {
            this.html = '<p>模拟 Ajax 异步设置内容 HTML</p>'
        }, 1500)
    },
    beforeDestroy() {
        const editor = this.editor
        if (editor == null) return
        editor.destroy() // 组件销毁时，及时销毁编辑器
    }
})
</script>
<style src="@wangeditor/editor/dist/css/style.css"></style>

2. vue3

<template>
    <div style="border: 1px solid #ccc">
      <Toolbar
        style="border-bottom: 1px solid #ccc"
        :editor="editorRef"
        :defaultConfig="toolbarConfig"
        :mode="mode"
      />
      <Editor
        style="height: 500px; overflow-y: hidden;"
        v-model="valueHtml"
        :defaultConfig="editorConfig"
        :mode="mode"
        @onCreated="handleCreated"
      />
    </div>
</template>
<script>
import '@wangeditor/editor/dist/css/style.css' // 引入 css

import { onBeforeUnmount, ref, shallowRef, onMounted } from 'vue'
import { Editor, Toolbar } from '@wangeditor/editor-for-vue'

export default {
  components: { Editor, Toolbar },
  setup() {
    // 编辑器实例，必须用 shallowRef
    const editorRef = shallowRef()

    // 内容 HTML
    const valueHtml = ref('<p>hello</p>')

    // 模拟 ajax 异步获取内容
    onMounted(() => {
        setTimeout(() => {
            valueHtml.value = '<p>模拟 Ajax 异步设置内容</p>'
        }, 1500)
    })

    const toolbarConfig = {}
    const editorConfig = { placeholder: '请输入内容...' }

    // 组件销毁时，也及时销毁编辑器
    onBeforeUnmount(() => {
        const editor = editorRef.value
        if (editor == null) return
        editor.destroy()
    })

    const handleCreated = (editor) => {
      editorRef.value = editor // 记录 editor 实例，重要！
    }

    return {
      editorRef,
      valueHtml,
      mode: 'default', // 或 'simple'
      toolbarConfig,
      editorConfig,
      handleCreated
    };
  }
}
</script>

四、文件上传问题

此处以vue2 Springboot为例，代码仅供参考

前端

前端重点在于editorConfig中fileName及server的配置

<template>
    <div>
        <div class="editor-container">
            <Toolbar :editor="editor" :defaultConfig="toolbarConfig" :mode="mode" />
            <el-button @click="save">保存</el-button>
            <el-button @click="clear">清空</el-button>
            <Editor v-model="html" :defaultConfig="editorConfig" :mode="mode" @onCreated="onCreated" />
        </div>
    </div>
</template>
    
<script>
import { Editor, Toolbar } from '@wangeditor/editor-for-vue';

export default {
    components: {
        Editor,
        Toolbar
    },
    data() {
        return {
            editor: null,
            html: '<p>文章内容</p>',
            toolbarConfig: {},
            editorConfig: {
                placeholder: '请输入内容...',
                MENU_CONF: {
                    uploadImage: {
                        fieldName: 'file',
                        server: 'http://localhost:8082/file/uploadTest'
                    }
                }
            },
            mode: 'default'
        };
    },
    methods: {
        save() {
            this.$store.state.articleContent = this.html;
        },
        clear() {
            this.html = '';
        },
        onCreated(editor) {
            this.editor = Object.seal(editor);
        }
    },
    mounted() {
        setTimeout(() => {
            this.html = '<p>暂不支持视频，提交前记得保存</p>';
        }, 2000);
    },
    beforeDestroy() {
        const editor = this.editor;
        if (editor == null) return;
        editor.destroy();
    }
};
</script>
    
<style src="@wangeditor/editor/dist/css/style.css"></style>
<style>

.editor-container {
    border: 1px solid #ccc;
}

.editor-container>* {
    border-bottom: 1px solid #ccc;
}

.editor-container>button {
    border: 0;
}

.editor-container>.w-e-text-container {
    height: 500px;
    overflow-y: hidden;
}

</style>

后端

后端重点在于返回类型及文件大小配置

import com.alibaba.fastjson.JSONObject;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.multipart.MultipartFile;

import javax.servlet.http.HttpServletRequest;
import java.io.File;
import java.io.IOException;

@RestController
@CrossOrigin
@RequestMapping("/file")
public class FileController {


    @PostMapping("/uploadTest")
    @CrossOrigin
    public JSONObject uploadTest(@RequestParam(value = "file", required = false) MultipartFile file,HttpServletRequest request) throws Exception {
        String url = upload(file,request);
        JSONObject jsonObject = new JSONObject();
        if(url != null){
            jsonObject.put("errno",0);
            JSONObject jsonObject1 = new JSONObject();
            jsonObject1.put("url",url);
            jsonObject1.put("alt","a2-w1p.jpeg");
            jsonObject1.put("href",url);
            jsonObject.put("data",jsonObject1);
        }else {
            jsonObject.put("errno",1);
            jsonObject.put("message","上传图片失败");
        }
        return jsonObject;
    }

    @PostMapping("/upload")
    public String upload(@RequestParam("file") MultipartFile file, HttpServletRequest request) throws IOException {
        String filename = file.getOriginalFilename();
        String path = request.getServletContext().getRealPath("/upload/");
        saveFile(file, path);
        return "http://localhost:8082/upload/"   filename;
    }

    public void saveFile(MultipartFile f, String path) throws IOException {
        File upDir = new File(path);
        if (!upDir.exists()) {
            upDir.mkdir();
        }
        File file = new File(path   f.getOriginalFilename());
        f.transferTo(file);
    }

}

yml文件大小配置

  servlet:
    multipart:
      # 上传文件的最大大小限制
      max-file-size: 10MB
      # 请求的最大大小限制
      max-request-size: 10MB
