resolve({ default: result['attachment'] })
返回的resolve必须要带default,后面跟附件路径

  upload() {
      let upload = new Promise((resolve, reject)=>{
        this.loader['file'].then(
            (data)=>{
                this.uploadFile(data,this.url,'sherry')
                .subscribe(
                    (result)=>{
                        console.log('result',result);
                        resolve({ default: result['attachment'] })
                    },
                    (error)=>{
                        reject(data.msg);
                    }
                );
            }
        );
      });
      return upload;
  }
