4.2.7 框架之翻译工具

一、说明

Oinone目前的默认文案是中文，如果需要使用其他语言，Oinone也提供一系列的翻译能力。

二、定义语言文件

在src/local下新增一个名为zh_cn.ts文件:

编辑zh_cn.ts文件，增加以下内容：

const zhCN = {
    demo: {
        test: '这是测试'
    }
}

export default zhCN

在mian.ts注册语言资源：

import { LanguageType, registryLanguage} from '@kunlun/dependencies';
import Zh_cn from './local/zh_cn'
registryLanguage(LanguageType['zh-CN'], Zh_cn);

三、Vue模板使用

<template>
  <div class="petFormWrapper">
    <form :model="formState" @finish="onFinish">
      <a-form-item :label="translate('demo.test')" id="name" name="kind" :rules="[{ required: true, message: '请输入品种种类!', trigger: 'focus' }]">
        <a-input v-model:value="formState.kind" @input="(e) => onNameChange(e, 'kind')" />
        <span style="color: red">{{ getServiceError('kind') }}</span>
      </a-form-item>

      <a-form-item label="品种名" id="name" name="name" :rules="[{ required: true, message: '请输入品种名!', trigger: 'focus' }]">
        <a-input v-model:value="formState.name" @input="(e) => onNameChange(e, 'name')" />
        <span style="color: red">{{ getServiceError('name') }}</span>
      </a-form-item>
    </form>
  </div>
</template>

<script lang="ts">
import { defineComponent, reactive } from 'vue';
import { Form } from 'ant-design-vue';

export default defineComponent({
  // 引入translate
  props: ['onChange', 'reloadData', 'serviceErrors', 'translate'],
  components: { Form },
  setup(props) {
    const formState = reactive({
      kind: '',
      name: '',
    });

    const onFinish = () => {
      console.log(formState);
    };

    const onNameChange = (event, name) => {
      props.onChange(name, event.target.value);
    };

    const reloadData = async () => {
      await props.reloadData();
    };

    const getServiceError = (name: string) => {
      const error = props.serviceErrors.find(error => error.name === name);
      return error ? error.error : '';
    }

    return {
      formState,
      reloadData,
      onNameChange,
      onFinish,
      getServiceError
    };
  }
});
</script>

效果

四、JS使用-translate

<template>
  <div class="petFormWrapper">
    <form :model="formState" @finish="onFinish">
      <a-form-item :label="translate('demo.test')" id="name" name="kind" :rules="[{ required: true, message: '请输入品种种类!', trigger: 'focus' }]">
        <a-input v-model:value="formState.kind" @input="(e) => onNameChange(e, 'kind')" />
        <span style="color: red">{{ getServiceError('kind') }}</span>
      </a-form-item>

      <a-form-item label="品种名" id="name" name="name" :rules="[{ required: true, message: '请输入品种名!', trigger: 'focus' }]">
        <a-input v-model:value="formState.name" @input="(e) => onNameChange(e, 'name')" />
        <span style="color: red">{{ getServiceError('name') }}</span>
      </a-form-item>
    </form>
  </div>
</template>

<script lang="ts">
import { defineComponent, reactive, onMounted } from 'vue';
// 引入
import { translate } from '@kunlun/dependencies';
import { Form } from 'ant-design-vue';

export default defineComponent({
  props: ['onChange', 'reloadData', 'serviceErrors', 'translate'],
  components: { Form },
  setup(props) {
    const formState = reactive({
      kind: '',
      name: '',
    });

    const onFinish = () => {
      console.log(formState);
    };

    const onNameChange = (event, name) => {
      props.onChange(name, event.target.value);
    };

    const reloadData = async () => {
      await props.reloadData();
    };

    const getServiceError = (name: string) => {
      const error = props.serviceErrors.find(error => error.name === name);
      return error ? error.error : '';
    }

    onMounted(() => {
      // 使用
      const test = translate('demo.test');
      console.log(test);
    });

    return {
      formState,
      reloadData,
      onNameChange,
      onFinish,
      getServiceError
    };
  }
});
</script>

五、JS使用-translateValueByKey

translateValueByKey和translate的区别是，获取资源的路径不同，translate从前端定义中获取对应的翻译，translateValueByKey是从平台翻译功能中配置得来。建议使用

import { translateValueByKey } from '@kunlun/dependencies';
translateValueByKey("中文名称") || "默认值"

六、翻译dslNode

处理xml的国际化

import { translateNode } from '@kunlun/translateValueByKey';
translateNode(dslNode);
