How to set up robots.txt to allow crawling of some pages while disallowing crawling of resource files?

When you need to allow some pages to be crawled while blocking resource files, you can achieve this by combining the Allow and Disallow directives in the robots.txt file. Typically, you first need to specify the target crawler (e.g., using "*" to represent all crawlers), and then configure the allow and disallow rules accordingly. Specific setup methods: - Allow partial pages: Use the Allow directive to specify the page paths to be crawled. For example, to allow crawling of all content under the "/blog/" directory, you can write `Allow: /blog/`. - Block resource files: Block specific types of resources using the Disallow directive. Common resource file extensions include .css, .js, .jpg, .png, etc. You can write `Disallow: /*.css$`, `Disallow: /*.js$`, `Disallow: /*.jpg$`, etc. (The "$" indicates matching the end to avoid mistakenly blocking other content). After completing the configuration, it is recommended to use a robots.txt testing tool (such as Google Search Console's robots testing tool) to verify if the rules are effective and ensure the paths are written correctly (e.g., avoid extra slashes or incorrect case).
