MES项目点
一、项目局域网访问地址创建

host: '0.0.0.0',

二、select下拉表单内容
1、默认值设置为undefined，placeholder才生效

<a-col :sm="24" :md="12" :xl="6">
          <a-form-item
            name="opeCodeList"
            :rules="[
              {
                required: true,
                message: $t('input.Pleaseselect') + $t('table.Process'),
              },
            ]"
            :label="$t('table.Process')"
          >
            <a-select
              v-model:value="formState.opeCodeList"
              :getPopupContainer="trigger => trigger.parentNode"
              :placeholder="$t('input.Pleaseselect') + $t('table.Process')"
              allow-clear
              @select="getToolList"
            >
              <a-select-option
                v-for="item in opeList"
                :id="item.id"
                :key="item.id"
                :value="item.opeCode"
              >
                {{ item.opeName }}
              </a-select-option>
            </a-select>
          </a-form-item>
        </a-col>

2、重新绑定label和value

:fieldNames="{ label: 'name', value: 'id' }"
