onUpload(e){
      var formData = new FormData(); 
    f ormData.append('file', e.target.files[0]);
    formData.append('type', 'test');
      $.ajax({
        url: '/ShopApi/util/upload.weixun'，//这里是后台接口需要换掉
        type: 'POST',
        dataType: 'json',
        cache: false,
        data: formData,
        processData: false,
        contentType: false,
        success: (res) => {        
          if (res.code === 200) {
            var img_tpl =&#39;<p class="picture" style="width:108px;float:left;"><img id="preview" src="&#39;+后台返回的tu&#39;pian路径+&#39;" style="width:48px;height:48px;float:left;background-size:cover;"/><span class="r-span"
