这篇文章介绍一下富文本编辑器,包括代码和实现
1.首先介入一个富文本的Demo,先看一下代码
<!DOCTYPE HTML>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>ueditor demo</title>
<script
type="text/javascript"
src="https://cdn.jsdelivr.net/npm/wangeditor@latest/dist/wangEditor.min.js"
></script>
<script src="esdk-obs-browserjs.3.22.3.min.js"></script>
</head>
<body>
<!-- 加载编辑器的容器 -->
<div id="div1">
<p>欢迎使用 <b>wangEditor</b> 富文本编辑器</p>
</div>
<!-- 引入 wangEditor.min.js -->
<script type="text/javascript">
const E = window.wangEditor
const editor = new E('#div1')
// 或者 const editor = new E( document.getElementById('div1') )
editor.config.menuTooltipPosition = 'down'
editor.config.showLinkImg = false
editor.config.debug = true;
// 关闭粘贴内容中的样式
editor.config.pasteFilterStyle = false
// 忽略粘贴内容中的图片
editor.config.pasteIgnoreImg = true
// 使用 base64 保存图片
//editor.customConfig.uploadImgShowBase64 = true
// 上传图片到服务器
editor.config.uploadFileName = 'myFile'; //设置文件上传的参数名称
editor.config.uploadImgServer = 'upload.do'; //设置上传文件的服务器路径
editor.config.uploadImgMaxSize = 3 * 1024 * 1024; // 将图片大小限制为 3M
editor.config.customUploadImg = (resultFiles, insertImgFn)=>{
// resultFiles 是 input 中选中的文件列表
// insertImgFn 是获取图片 url 后，插入到编辑器的方法
var bb=resultFiles[0];
//alert(JSON.stringify(bb));
//alert(JSON.stringify(insertImgFn));
// 上传图片，返回结果，将图片插入到编辑器中
// var objname= "deploy/ringpai/upload/dcm/" + 123456789 + ".png";
// obsClient.putObject({
// Bucket : 'ringpai-phis',
// Key : 'objname',
// SourceFile : document.getElementById('input-file').files[0]
//}, function (err, result) {
// if(err){
// console.error('Error-->' + err);
// }else{
// alert(JSON.stringify(result));
// console.log('Status-->' + result.CommonMsg.Status);
// }
//});
//insertImgFn(imgUrl)
}
editor.config.uploadImgHooks = {
before: function(xhr, editor, files) {
alert(JSON.stringify(files));
},
success: function(xhr, editor, result) {
console.log("上传成功");
},
fail: function(xhr, editor, result) {
console.log("上传失败,原因是" + result);
},
error: function(xhr, editor) {
console.log("上传出错");
},
timeout: function(xhr, editor) {
console.log("上传超时");
}
}
editor.create()
var obsClient = new ObsClient({
access_key_id: 'OHECMDFOILGX92Z3XDQC',
secret_access_key: 'OtxQhPAocSx0ZizvXCCMXlWVQ1GVJq2ByPsjBDNd',
server : 'obs.cn-north-4.myhuaweicloud.com'
});
// alert(obsClient);
</script>
</body>
</html>这里需要引入一个js包,代码中也有体现,样式大概是下面这种
2.实际的应用(包含接口的编写)
以下的代码只能参考,不能完全粘贴复用,我这里的富文本是一个弹出的界面,只列出富文本的代码,主页面没有列出;可以看代码注释,上传图片视频的接口也会列出,存储文本,回显等接口就不列出了图片和视频的存储是通过华为云进行的,先存到华为云,然后把url存储到数据库中,实现回显

<style>
.LAY-custservice-visit-clickMe {
color: #077aff;
padding: 0 5px;
text-decoration: revert;
cursor: pointer;
}
.w-e-text-container {
height: 420px !important; /*!important是重点，因为原div是行内样式设置的高度300px*/
}
</style>以下是存储到华为云的基本代码,只列出基本的代码,仅供参考
@Override
public String yunUploadFile(MultipartFile file) throws Exception {
String ak = "";
String sk = "";
String endPoint = "";
String bucketName = "";
//设置链接失效时间
// long expireSeconds = 3600 * 24 * 365L;
// 得到文件原名
String fileName = "sysnotifacation/" + file.getOriginalFilename();
InputStream inputStream = file.getInputStream();
//创建云服务器
ObsClient obsClient = new ObsClient(ak, sk, endPoint);
PutObjectResult putObjectResult = obsClient.putObject(bucketName, fileName, inputStream);
int statusCode = putObjectResult.getStatusCode();
String obsurl = putObjectResult.getObjectUrl();
logger.info("-------OBS上传状态为：" + statusCode);
logger.info("-------文件的全路径为：" + obsurl);
inputStream.close();
// // 创建ObsClient实例
// TemporarySignatureRequest request = new TemporarySignatureRequest(HttpMethodEnum.GET, expireSeconds);
// request.setBucketName(bucketName);
// request.setObjectKey(file.getOriginalFilename());
//
// // 设置图片处理参数，对图片依次进行缩放、旋转
// Map<String, Object> queryParams = new HashMap<String, Object>();
// queryParams.put("x-image-process", "image/resize,m_fixed,w_100,h_100/rotate,90");
// request.setQueryParams(queryParams);
//
// // 生成临时授权URL
// TemporarySignatureResponse response = obsClient.createTemporarySignature(request);
// System.out.println(response.getSignedUrl());
obsClient.close();
// return response.getSignedUrl();
return obsurl;
}定义的参数根据自己华为云的参数来写就行,其他的数据接口不展示
以上的代码仅供参考,不能复用,有问题可以私信一起研究哈
