这是我数据库中存放的图片的路径：

D:\data\temp\\1566005346231.jpg

这是我前端的代码

for (var i = 0; i < data.list.length; i++) {
                    var product = data.list[i];
                    console.log(product);
                    if (product.productStatus == "1") {
                        product.productStatus = "已上架"
                    } else {
                        product.productStatus = "未上架"
                    }
                    var tmp = "<tr>\n" +
                        "            <td>" + product.productBarcode + "</td>\n" +
                        "            <td>" + product.productName + "</td>\n" +
                        "            <td>" + product.productPrice + "</td>\n" +
                        "            <td>" + product.productStandard + "</td>\n" +
                        "            <td><img src='"+product.productImage+"'></td>\n" + 这块就是要显示图片的地方
                        "            <td>" + product.productSort + "</td>\n" +
                        "            <td>" + product.productStatus + "</td>\n" +

                        "        </tr>";
                    list_html += tmp;
