Sitemap
Sitemaps XML format
The Sitemap protocol format consists of XML tags. All data values in a Sitemap must be entity-escaped. The file itself must be UTF-8 encoded.
The Sitemap must:
- Begin with an opening <urlset> tag and end with a closing </urlset> tag.
- Specify the namespace (protocol standard) within the <urlset> tag.
- Include a <url> entry for each URL, as a parent XML tag.
- Include a <loc> child entry for each <url> parent tag.
Sample XML Sitemap
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>http://www.example.com/</loc>
<lastmod>2005-01-01</lastmod>
<changefreq>monthly</changefreq>
<priority>0.8</priority>
</url>
</urlset>
在项目根目录下动态生成 sitemap.xml
1. 安装依赖
# install dependency
$ npm i @nuxtjs/sitemap # Or yarn add @nuxtjs/sitemap
2. 修改 nuxt.config.js 文件
const axios = require("axios"); // cannot use import
module.exports = {
modules: [ "@nuxtjs/axios", "@nuxtjs/sitemap" ], // always declare the sitemap module at end of array
sitemap: {
gzip: true,
exclude: [
"/login",
"/search-result",
"/search-result/**",
"/reset-password/**",
"/user-center/**",
],
defaults: {
priority: .5,
lastmod: "2019-06-12",
changefreq: "monthly"
},
async routes () {
const getUsersRes = await getUsers();
if (!getUsersRes) return;
return [
{
url: "/",
priority: 1,
lastmod: "2019-06-12",
changefreq: "monthly",
},
...getUsersRes
];
function getUsers() {
return new Promise((resolve, reject) => {
axios({
method: "GET",
url: "https://jsonplaceholder.typicode.com/users"
})
.then(res => {
resolve(res.data.map(user => '/users/' + user.username));
}).catch(err => {
reject();
});
});
}
}
}
}
2.1 Configuration
- routes
- 值类型可以为 Array 或 Function
- Array / routes: [ { url: "/", priority: 1, lastmod: "2019-06-12", changefreq: "monthly" } ]
- Function / routes() { return axios({ method: "GET", url: ".../users" }).then(res => res.data.map(user => "/users/" + user.username)) }
- defaults
- The defaults parameter set the default options for all routes.
- exclude
- The exclude parameter is an array of glob patterns to exclude static routes from the generated sitemap.
3. 修改 robots.txt 文件
显示添加 Sitemap: https://www.data4industry.com/sitemap.xml
到 robots.txt 文件中
User-agent: *
Request-rate: 1/1
Crawl-delay: 60
Disallow: /user-center
Disallow: /user-terms-of-use
Disallow: /user-privacy-protocol
Disallow: /search-result
Sitemap: https://www.data4industry.com/sitemap.xml
