API 封装//

请求拦截器apiClient.interceptors.request.use((config){constauthStoreuseAuthStore();if(authStore.token){config.headers.AuthorizationBearer${authStore.token};}returnconfig;},(error)Promise.reject(error));// 响应拦截器apiClient.interceptors.response.use((response)response.data,(error){if(error.response?.status401){constauthStoreuseAuthStore();authStore.logout();router.push(/login);}returnPromise.reject(error);});exportdefaultapiClient;4.2 产品管理 API//

Pinia 状态管理//

Vue 3 组合式组件!-- frontend/src/views/ProductList.vue -- script setup langts import { onMounted, ref } from vue; import { useProductStore } from /stores/products; import { ElMessage, ElMessageBox } from element-plus; import type { Product } from /api/products; import ProductForm from /components/ProductForm.vue; const store useProductStore(); const showForm ref(false); const editingProduct refProduct | null(null); const searchQuery ref(); onMounted(() { store.fetchProducts(); }); function handleSearch() { store.fetchProducts({ search: searchQuery.value || undefined }); } function handlePageChange(page: number) { store.currentPage page; store.fetchProducts(); } function handleCreate() { editingProduct.value null; showForm.value true; } function handleEdit(product: Product) { editingProduct.value { ...product }; showForm.value true; } async function handleDelete(product: Product) { try { await ElMessageBox.confirm( 确定要删除产品「${product.name}」吗, 确认删除, { type: warning } ); await store.deleteProduct(product.id); ElMessage.success(删除成功); } catch { // 取消操作 } } async function handleFormSubmit(data: any) { try { if (editingProduct.value) { await store.updateProduct(editingProduct.value.id, data); ElMessage.success(更新成功); } else { await store.createProduct(data); ElMessage.success(创建成功); } showForm.value false; } catch (e: any) { ElMessage.error(e.response?.data?.detail || 操作失败); } } /script template div classproduct-list div classtoolbar el-input v-modelsearchQuery placeholder搜索产品... keyup.enterhandleSearch stylewidth: 300px

Docker的全栈技术栈组合在2026年已经成为Python全栈开发的事实标准。这套组合的优势在于FastAPI原生异步、自动文档、类型安全开发效率极高Vue 3Composition API、响应式系统、Pinia状态管理前端开发体验极佳Docker一键部署、环境隔离、易于扩展运维成本极低完整的全栈开发流程先设计数据模型→编写后端API→定义Pydantic Schema→开发前端页面→前后端联调→Docker部署。每一步都有清晰的最佳实践开发者可以专注于业务逻辑而非基础设施。对于想要快速交付全栈项目的团队来说这套技术栈组合是2026年最高效的选择。
