二、RESTful API基础集成
2.1 构建标准化API服务
基于TypeScript接口定义数据模型，通过分层设计实现API服务的标准化。以下是符合Open/Closed原则的服务层实现：
// src/types/Product.ts - 定义数据模型
export interface Product {
id: string;
code: string;
name: string;
price: number;
category: string;
inventoryStatus: 'INSTOCK' | 'LOWSTOCK' | 'OUTOFSTOCK';
rating: number;
}
// src/services/ApiService.ts - 基础API服务
export abstract class ApiService {
protected baseUrl: string;
constructor(baseUrl: string) {
this.baseUrl = baseUrl;
}
protected async request<T>(
endpoint: string,
options: RequestInit = {}
): Promise<T> {
const url = `${this.baseUrl}/${endpoint}`;
const headers = {
'Content-Type': 'application/json',
...options.headers
};
try {
const response = await fetch(url, { ...options, headers });
if (!response.ok) {
const error = await response.json().catch(() => ({}));
throw new Error(error.message || `HTTP error! status: ${response.status}`);
}
return await response.json() as T;
} catch (error) {
console.error(`[ApiService] Request failed: ${error.message}`);
throw error; // 向上传播错误，由调用方处理
}
}
}
2.2 实现CRUD操作服务
以产品管理为例，实现符合RESTful规范的CRUD操作：
// src/services/ProductService.ts
import { ApiService } from './ApiService';
import { Product } from '../types/Product';
export class ProductService extends ApiService {
constructor() {
super('https://api.example.com/products');
}
// 获取产品列表（支持分页、排序、过滤）
async getProducts(params: {
page?: number;
limit?: number;
sort?: string;
order?: 'asc' | 'desc';
category?: string;
}): Promise<{ data: Product[], total: number }> {
const queryParams = new URLSearchParams();
Object.entries(params).forEach(([key, value]) => {
if (value !== undefined) queryParams.append(key, value.toString());
});
return this.request<{ data: Product[], total: number }>(
`?${queryParams.toString()}`,
{ method: 'GET' }
);
}
// 获取单个产品详情
async getProduct(id: string): Promise<Product> {
return this.request<Product>(`/${id}`, { method: 'GET' });
}
// 创建新产品
async createProduct(product: Omit<Product, 'id'>): Promise<Product> {
return this.request<Product>('', {
method: 'POST',
body: JSON.stringify(product)
});
}
// 更新产品信息
async updateProduct(id: string, product: Partial<Product>): Promise<Product> {
return this.request<Product>(`/${id}`, {
method: 'PUT',
body: JSON.stringify(product)
});
}
// 删除产品
async deleteProduct(id: string): Promise<{ success: boolean }> {
return this.request<{ success: boolean }>(`/${id}`, {
method: 'DELETE'
});
}
}
三、PrimeVue组件数据绑定实践
3.1 DataTable与API集成
PrimeVue的DataTable组件是实现数据展示的核心控件，以下是一个完整的产品列表实现，包含分页、排序、过滤功能：
<template>
<div class="card">
<h5>产品列表</h5>
<DataTable
:value="products"
:loading="loading"
:totalRecords="totalRecords"
:rows="rows"
:first="first"
:paginator="true"
:sortMode="sortMode"
:multiSortMeta="multiSortMeta"
@page="onPageChange"
@sort="onSortChange"
>
<Column field="code" header="产品编码" sortable></Column>
<Column field="name" header="产品名称" sortable></Column>
<Column field="category" header="类别" sortable>
<template #filter="{ filterCallback }">
<InputText
v-model="categoryFilter"
@input="filterCallback()"
placeholder="搜索类别"
/>
</template>
</Column>
<Column field="price" header="价格" sortable>
<template #body="slotProps">
¥{{ slotProps.data.price.toFixed(2) }}
</template>
</Column>
<Column field="inventoryStatus" header="库存状态" sortable>
<template #body="slotProps">
<Badge
:severity="
slotProps.data.inventoryStatus === 'INSTOCK' ? 'success' :
slotProps.data.inventoryStatus === 'LOWSTOCK' ? 'warning' : 'danger'
"
>
{{ slotProps.data.inventoryStatus }}
</Badge>
</template>
</Column>
<Column header="操作">
<template #body="slotProps">
<Button
icon="pi pi-pencil"
severity="primary"
size="sm"
@click="editProduct(slotProps.data)"
></Button>
<Button
icon="pi pi-trash"
severity="danger"
size="sm"
class="ml-2"
@click="deleteProduct(slotProps.data.id)"
></Button>
</template>
</Column>
</DataTable>
<!-- 错误提示 -->
<Message
v-if="error"
severity="error"
closable
@close="error = null"
>
{{ error }}
</Message>
</div>
</template>
<script setup lang="ts">
import { ref, onMounted, reactive } from 'vue';
import { DataTable, Column } from 'primevue/datatable';
import { Button } from 'primevue/button';
import { InputText } from 'primevue/inputtext';
import { Badge } from 'primevue/badge';
import { Message } from 'primevue/message';
import { ProductService } from '@/services/ProductService';
import type { Product } from '@/types/Product';
// 服务实例
const productService = new ProductService();
// 状态管理
const products = ref<Product[]>([]);
const totalRecords = ref(0);
const loading = ref(true);
const error = ref<string | null>(null);
// 分页控制
const rows = ref(10);
const first = ref(0);
const sortMode = ref('multiple');
const multiSortMeta = ref<{ field: string, order: number }[]>([]);
const categoryFilter = ref('');
// 生命周期钩子
onMounted(() => {
fetchProducts();
});
// 数据获取方法
const fetchProducts = async () => {
loading.value = true;
try {
const params: any = {
page: first.value / rows.value + 1,
limit: rows.value,
category: categoryFilter.value || undefined
};
// 处理排序参数
if (multiSortMeta.value.length > 0) {
params.sort = multiSortMeta.value.map(m => m.field).join(',');
params.order = multiSortMeta.value.map(m => m.order === 1 ? 'asc' : 'desc').join(',');
}
const result = await productService.getProducts(params);
products.value = result.data;
totalRecords.value = result.total;
error.value = null;
} catch (err) {
error.value = err instanceof Error ? err.message : '获取产品数据失败';
console.error('产品数据获取失败:', err);
} finally {
loading.value = false;
}
};
// 分页事件处理
const onPageChange = (event: any) => {
first.value = event.first;
rows.value = event.rows;
fetchProducts();
};
// 排序事件处理
const onSortChange = (event: any) => {
multiSortMeta.value = event.multiSortMeta;
fetchProducts();
};
// 编辑产品
const editProduct = (product: Product) => {
// 编辑逻辑
};
// 删除产品
const deleteProduct = async (id: string) => {
if (confirm('确定要删除此产品吗？')) {
try {
await productService.deleteProduct(id);
fetchProducts(); // 重新加载数据
// 显示成功提示
useToast().add({ severity: 'success', summary: '成功', detail: '产品已删除' });
} catch (err) {
error.value = err instanceof Error ? err.message : '删除产品失败';
}
}
};
</script>
3.2 表单组件与API交互
PrimeVue的表单组件可以与RESTful API无缝集成，实现数据的创建和更新功能。以下是一个产品创建表单的实现：
<template>
<div class="card">
<h5>{{ isEdit ? '编辑产品' : '创建产品' }}</h5>
<Form @submit.prevent="handleSubmit" v-slot="{ valid, invalid }">
<div class="grid">
<div class="col-12 md:col-6">
<InputText
v-model="product.name"
label="产品名称"
required
:disabled="submitting"
/>
</div>
<div class="col-12 md:col-6">
<InputText
v-model="product.code"
label="产品编码"
required
:disabled="isEdit || submitting"
/>
</div>
<div class="col-12 md:col-6">
<InputNumber
v-model="product.price"
label="价格"
required
:min="0"
:step="0.01"
:disabled="submitting"
/>
</div>
<div class="col-12 md:col-6">
<Select
v-model="product.category"
label="类别"
required
:disabled="submitting"
>
<Option value="Accessories">配件</Option>
<Option value="Clothing">服装</Option>
<Option value="Electronics">电子产品</Option>
<Option value="Fitness">健身器材</Option>
</Select>
</div>
<div class="col-12">
<Textarea
v-model="product.description"
label="产品描述"
rows="3"
:disabled="submitting"
/>
</div>
<div class="col-12 flex justify-end gap-2 mt-4">
<Button
label="取消"
@click="onCancel"
:disabled="submitting"
/>
<Button
label="保存"
type="submit"
severity="primary"
:disabled="!valid || submitting"
:loading="submitting"
/>
</div>
</div>
</Form>
</div>
</template>
<script setup lang="ts">
import { ref, reactive, toRefs, onMounted } from 'vue';
import { Form, Field } from 'primevue/form';
import { InputText } from 'primevue/inputtext';
import { InputNumber } from 'primevue/inputnumber';
import { Select, Option } from 'primevue/select';
import { Textarea } from 'primevue/textarea';
import { Button } from 'primevue/button';
import { ProductService } from '@/services/ProductService';
import type { Product } from '@/types/Product';
import { useToast } from 'primevue/usetoast';
import { useRoute, useRouter } from 'vue-router';
const toast = useToast();
const route = useRoute();
const router = useRouter();
const productService = new ProductService();
// 状态管理
const isEdit = ref(!!route.params.id);
const submitting = ref(false);
const product = reactive<Partial<Product>>({
name: '',
code: '',
price: 0,
category: '',
description: ''
});
// 生命周期钩子
onMounted(async () => {
if (isEdit.value) {
await loadProduct(route.params.id as string);
}
});
// 加载产品数据
const loadProduct = async (id: string) => {
try {
const data = await productService.getProduct(id);
Object.assign(product, data);
} catch (err) {
toast.add({
severity: 'error',
summary: '加载失败',
detail: err instanceof Error ? err.message : '无法加载产品数据'
});
router.back();
}
};
// 表单提交处理
const handleSubmit = async () => {
submitting.value = true;
try {
if (isEdit.value) {
await productService.updateProduct(route.params.id as string, product);
toast.add({ severity: 'success', summary: '成功', detail: '产品已更新' });
} else {
await productService.createProduct(product as Omit<Product, 'id'>);
toast.add({ severity: 'success', summary: '成功', detail: '产品已创建' });
}
router.push('/products');
} catch (err) {
toast.add({
severity: 'error',
summary: '提交失败',
detail: err instanceof Error ? err.message : '操作失败，请重试'
});
} finally {
submitting.value = false;
}
};
// 取消操作
const onCancel = () => {
router.back();
};
</script>
四、错误处理与用户反馈
4.1 错误处理策略
在RESTful API集成中，错误处理是保障用户体验的关键环节。PrimeVue提供了Message和Toast组件，结合try-catch机制，可以实现全面的错误处理策略：
// src/services/ErrorService.ts - 错误处理服务
import { useToast } from 'primevue/usetoast';
export enum ErrorType {
NETWORK = '网络错误',
SERVER = '服务器错误',
VALIDATION = '数据验证错误',
AUTHENTICATION = '身份验证错误',
AUTHORIZATION = '权限不足',
NOT_FOUND = '资源不存在',
RATE_LIMIT = '请求频率限制',
UNKNOWN = '未知错误'
}
export class ApiError extends Error {
type: ErrorType;
statusCode?: number;
errors?: Record<string, string[]>;
constructor(
message: string,
type: ErrorType = ErrorType.UNKNOWN,
statusCode?: number,
errors?: Record<string, string[]>
) {
super(message);
this.name = 'ApiError';
this.type = type;
this.statusCode = statusCode;
this.errors = errors;
}
}
export const useApiErrorHandler = () => {
const toast = useToast();
const handleError = (error: unknown): ApiError => {
let apiError: ApiError;
if (error instanceof ApiError) {
apiError = error;
} else if (error instanceof Error) {
// 网络错误处理
if (error.message.includes('Failed to fetch')) {
apiError = new ApiError(
'无法连接到服务器，请检查网络连接',
ErrorType.NETWORK
);
} else {
apiError = new ApiError(error.message);
}
} else {
apiError = new ApiError('发生未知错误', ErrorType.UNKNOWN);
}
// 显示错误提示
toast.add({
severity: 'error',
summary: apiError.type,
detail: apiError.message,
life: 6000
});
return apiError;
};
// 处理表单验证错误
const handleValidationErrors = (errors: Record<string, string[]>) => {
const errorMessages: string[] = [];
for (const field in errors) {
errorMessages.push(`${field}: ${errors[field].join('; ')}`);
}
toast.add({
severity: 'error',
summary: ErrorType.VALIDATION,
detail: errorMessages.join('<br>'),
life: 10000,
dangerouslyUseHTMLString: true
});
};
return { handleError, handleValidationErrors };
};
4.2 服务层集成错误处理
// src/services/ProductService.ts (增强错误处理)
import { ApiService } from './ApiService';
import { Product } from '../types/Product';
import { ApiError, ErrorType } from './ErrorService';
export class ProductService extends创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
