CKEditor+腾讯云对象存储

解决问题：1、服务器之前来回的挂载

2、图片上传后经过编辑器被压缩

版本信息：ckeditor_4.11.1_full

下载地址：https://ckeditor.com/ckeditor-4/download/

1、将ckeditor放入项目的静态文件夹中

2、打开ckeditor/plugins/image/dialogs/image.js文件，搜索“b.config.image_previewText”，(b.config.image_previewText||'')单引号中的内容全删了，

搜索“upload”可以找到这一段 id:'Upload',hidden:true实际上上传功能被隐藏了，把上面的true改成false，如果你的显示是hidden:!0,直接改成0即可，就可以显示了，再打开编辑器，就能找到上传功能了。

3、ckeditor/config.js文件设置上传到服务器按钮的事件URL，指定将上传的文件提交给那个URL进行处理

2腾讯云对象存储

文档地址：https://cloud.tencent.com/document/product/436/14102

介绍：对象存储（Cloud Object Storage，简称：COS）是腾讯云提供的一种存储海量文件的分布式存储服务，用户可通过网络随时存储和查看数据。腾讯云 COS 使所有用户都能使用具备高扩展性、低成本、可靠和安全的数据存储服务。

COS 通过控制台、 API、SDK 等多样化方式简单、快速地接入，实现了海量数据存储和管理。通过 COS 可以进行多格式文件的上传、下载和管理。腾讯云提供了直观的 Web 管理界面，同时遍布全国范围的 CDN 节点可以对文件下载进行加速。

腾讯云对象存储代码：

@Component("tXFileService")

public class TXFileServiceImpl implements TXFileService {

private static Logger logger = LoggerFactory.getLogger(TXFileServiceImpl.class);

private static String LOCAL_TARGET_ROUTE = "/mydata/PYTFileMng/upload/";//本地图片默认下载路径

@Value("${tx.secretId:-1}")

private String secretId;

@Value("${tx.secretKey:-1}")

private String secretKey;

@Value("${tx.bucketName:-1}")

private String bucketName;

@Value("${tx.region:-1}")

private String region;

@Reference

private CmqSendService cmqSendService;

private COSClient getCosClient() {

// 将本地文件上传到COS

// 1 初始化用户身份信息(secretId, secretKey)

COSCredentials cred = new BasicCOSCredentials(secretId, secretKey);

// 2 设置bucket的区域

ClientConfig clientConfig = new ClientConfig(new Region(region));

// 3 生成cos客户端

COSClient cosclient = new COSClient(cred, clientConfig);

return cosclient;

}

@Override

public String uploadImgPubFile(Map<String, Object> paramMap) throws Exception {

COSClient cosClient = getCosClient();

String upAddr = paramMap.get("upAddr").toString();

String oldUpStr = upAddr;

String localAddr = paramMap.get("localAddr").toString();

String baseAddr = paramMap.get("baseAddr").toString();

try {

// 如果上传路径不包含基础路径,则拼接上传路径

if (!upAddr.contains(baseAddr)) {

upAddr = baseAddr + upAddr;

}

PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, upAddr, new File(localAddr));

// 设置存储类型, 默认是标准(Standard), 低频(standard_ia)

putObjectRequest.setStorageClass(StorageClass.Standard);

cosClient.putObject(putObjectRequest);

return upAddr;

} catch (Exception e) {

logger.error("上传腾讯云对象存储失败:",e);

List<EmailMessageBean> beans = new ArrayList<EmailMessageBean>();

EmailMessageBean bean = new EmailMessageBean();

Map<String,Object> params = new HashMap<>();//请求参数

params.put("upStr", oldUpStr);

params.put("localAddr", localAddr);

params.put("baseAddr", baseAddr);

bean.setParams(params);

bean.setMailType(EmailType.ERROR_EMAIL);//错误邮件

bean.setContent(StringUtils.convertException(e));//错误信息

beans.add(bean);

cmqSendService.sendEmailMessage(beans);

} finally {

// 关闭客户端

cosClient.shutdown();

}

return null;

}

@Override

public String uploadImgPubFileByURL(Map<String, Object> paramMap) throws Exception {

COSClient cosClient = getCosClient();

String upAddr = paramMap.get("upAddr").toString();//腾讯云上传路径
