使用zig语言制作简单博客网站(五)编写博客首页数据请求响应代码
前端请求代码
请注意前端数据渲染我换成了vue.js
前端请求代码
<script type="module"> import { createApp, ref, onMounted, } from "./js/vue.esm-browser.prod.js"; createApp({ setup() { const articleList = ref([]); // 首页文章列表 const cateList = ref([]); // 首页分类列表 // 获取首页文章列表 const getArticleList = () => { $.ajax({ url: 'http://localhost:5588/api/home/articles', type: 'GET', dataType: 'json', success: function (res) { if (res.code == 200) { articleList.value = res.data; } }, error: function (err) { console.log(err.responseText); } }); }; // 获取首页分类列表 const getCateList = () => { $.ajax({ url: 'http://localhost:5588/api/home/cates', type: 'GET', dataType: 'json', success: function (res) { if (res.code == 200) { cateList.value = res.data; } }, error: function (err) { console.log(err.responseText); } }); }; onMounted(() => { getArticleList(); getCateList(); }); return { articleList, cateList, } } }).mount('#app') </script>
后端响应代码
首页文章
- 注册路由
// 首页博客列表 router.get("/api/home/articles", &articleController.getHomeArticles);
- 建立
article_controller.zig
文件,代码如下
const std = @import("std"); const httpz = @import("httpz"); const article_server = @import("../server/article_server.zig"); /// 获取首页文章列表 pub fn getHomeArticles(req: *httpz.Request, res: *httpz.Response) !void { _ = req; const articles = try article_server.getHomeArticles(); res.status = 200; try res.json(.{ .code = 200, .msg = "ok", .data = articles }, .{}); }
- 建立
article_server.zig
文件,代码如下
const std = @import("std"); const database = @import("../database/db.zig"); const ArticleModel = @import("../model/article.zig"); /// 获取首页文章列表 pub fn getHomeArticles() ![]ArticleModel.Article { var db = try database.OpenDb(); defer db.deinit(); const query = \\SELECT id, title, description, content, istop, created_at, updated_at FROM article ORDER BY created_at DESC LIMIT 8 OFFSET 0 ; var stmt = try db.prepare(query); defer stmt.deinit(); var gpa = std.heap.GeneralPurposeAllocator(.{}){}; const allocator = gpa.allocator(); const rows = try stmt.all( ArticleModel.Article, allocator, .{}, .{}, ); return rows; }
首页分类
- 注册路由
// 首页分类列表 router.get("/api/home/cates", &cateController.getHomeCategories);
- 建立
cate_controller.zig
文件,代码如下
const std = @import("std"); const httpz = @import("httpz"); const cate_server = @import("../server/cate_server.zig"); /// 获取首页分类列表 pub fn getHomeCategories(req: *httpz.Request, res: *httpz.Response) !void { _ = req; const cates = try cate_server.getHomeCategories(); res.status = 200; try res.json(.{ .code = 200, .msg = "ok", .data = cates }, .{}); }
- 建立
cate_server.zig
文件,代码如下
const std = @import("std"); const database = @import("../database/db.zig"); const CategoryModel = @import("../model/cate.zig"); /// 获取首页分类列表 pub fn getHomeCategories() ![]CategoryModel.Category { var db = try database.OpenDb(); defer db.deinit(); const query = \\SELECT id, name FROM category ; var stmt = try db.prepare(query); defer stmt.deinit(); var gpa = std.heap.GeneralPurposeAllocator(.{}){}; const allocator = gpa.allocator(); const rows = try stmt.all( CategoryModel.Category, allocator, .{}, .{}, ); return rows; }
