ngx-quill富文本框使用+图片上传

在网上找了很多angular的富文本框组件,体验最好的是Froala这一款,但是要收费.后面又找到了这ngx-quill.搜了下quill的使用方法但是很少说到图片上传.所以自己研究了一下.现在把它分享出来.

1. 安装ngx-quill

npm install --save ngx-quill

2.在index.html引入css

3.在模块中引入

import { QuillModule } from 'ngx-quill';

@NgModule({
  imports: [
    ...
    QuillModule
    ...
  ],
})
export class xxxModule { }

4.在对应的html中引入

5.在component中实现图片上传的处理器

public editor;

EditorCreated(quill) {
    const toolbar = quill.getModule('toolbar');
    toolbar.addHandler('image', this.imageHandler.bind(this));
    this.editor = quill;
  }

imageHandler() {
    const Imageinput = document.createElement('input');
    Imageinput.setAttribute('type', 'file');
    Imageinput.setAttribute('accept','image/png, image/gif, image/jpeg, image/bmp, image/x-icon');
    Imageinput.classList.add('ql-image');
    Imageinput.addEventListener('change', () => {
      const file = Imageinput.files[0];
      const data: FormData = new FormData();
      data.append('file', file, file.name);
      const header = new Headers();
      header.append('Accept', 'application/json');
      const options = new RequestOptions({ headers: header });
      if (Imageinput.files != null && Imageinput.files[0] != null) {
        this.http.post('http://xxxx/upload', data, options)
        .map(res => res.json())
        .subscribe(res => {
          const range = this.editor.getSelection(true);
          const index = range.index + range.length;
          this.editor.insertEmbed(range.index, 'image', 'http://'+res.url);
        });
      }
    });
    Imageinput.click();
  }

8.后台上传接口

@RequestMapping(value = "/upload", method = {RequestMethod.POST})
    @ResponseBody
    public FileUploadResponse upload(@RequestParam("file") MultipartFile file, HttpServletRequest request) {
        String remotePath = nginxServer + "/";
        // 判断文件夹是否存在，不存在则
        File targetFile = new File(basePath);
        if (!targetFile.exists()) {
            targetFile.mkdirs();
        }
        String uuid = UUID.randomUUID().toString().replaceAll("-", "");
        FileUploadResponse rs = new FileUploadResponse();
        String contentType = file.getContentType();
        String fileName = file.getOriginalFilename();
        String fileNameSuffix = fileName.substring(fileName.lastIndexOf("."), fileName.length());
        String fileNameNew = uuid + fileNameSuffix;
        try {
            Files.copy(file.getInputStream(), Paths.get(basePath, fileNameNew), StandardCopyOption.REPLACE_EXISTING);
            rs.setContentType(contentType);
            rs.setFileName(fileNameNew);
            rs.setUrl(remotePath + fileNameNew);
            rs.setType("success");
            log.info(JSON.toJSONString(rs));
        } catch (Exception e) {
            rs.setType("fail");
            rs.setMsg("文件上传失败！");
            log.error("上传文件失败，" + e);
        }
        return rs;
    }

9.富文本框内容需要转码(保存时转码,查看时解码)

/*用正则表达式实现html转码*/
  htmlEncodeByRegExp(str) {
    var s = "";
    if (str.length == 0) return "";
    s = str.replace(/&/g, "&");
    s = s.replace(//g, ">");
    s = s.replace(/\'/g, "'");
    s = s.replace(/\"/g, """);
    s = s.replace(/\n"/g, "");
    s = s.replace(/\r"/g, "");
    return s;
  }
  /*用正则表达式实现html解码*/
  htmlDecodeByRegExp(str) {
    var s = "";
    if (str.length == 0) return "";
    s = str.replace(/&/g, "&");
    s = s.replace(/</g, "<");
    s = s.replace(/>/g, ">");
    s = s.replace(/ /g, " ");
    s = s.replace(/'/g, "\'");
    s = s.replace(/"/g, "\"");
    return s;
  }
