Hi @solid pier. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#How to get index.astro dynamic parameter in SSG mode
flint marshBOT
In Astro, you can access the parameters from the URL using the Astro.params object. This object contains the values of dynamic route segments matched for the request.
Here's an example of how you can use Astro.params:
---
export function getStaticPaths() {
return [
{ params: { id: '1' } },
{ params: { id: '2' } },
{ params: { id: '3' } }
];
}
const { id } = Astro.params;
---
<h1>{id}</h1>
In this example, Astro.params is used to get the id parameter from the URL. The getStaticPaths function is used to define the possible values for id.
However, please note that with the default output: 'static' option, Astro.request.url does not contain search parameters, like ?foo=bar, as it’s not possible to determine them ahead of time during static builds. However in output: 'server' mode, Astro.request.url does contain search parameters as it can be determined from a server request.
For more information, you can refer to the Astro API Reference (https://docs.astro.build/en/reference/api-reference#astroparams) and Astro.request documentation (https://docs.astro.build/en/reference/api-reference#astrorequest).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@flint marsh the static file generated would be open and load different platform, how to achieve when onload index page able to identify the index page is loaded from which platform?

Let me check the knowledge base for you. One moment! :books:
To identify the platform from which the index page is loaded, you would typically use JavaScript to check the navigator.userAgent property. This property returns the user agent string for the current browser, which you can use to identify the platform.
However, Astro emphasizes minimized JavaScript usage and optimized loading times for an improved user experience. It's important to note that this approach would require client-side JavaScript to run, which might not align with Astro's philosophy of shipping less JavaScript.
If you want to perform this check server-side during the build process, you would need to have some way of knowing the platform at build time, which is typically not possible for static sites as the platform would be determined by the user's device at runtime.
If you're running in output: 'server' mode, you could potentially use the Astro.request.headers['user-agent'] to determine the platform server-side, but this information isn't available in the static output mode.
For more information, you can refer to the Astro API Reference (https://docs.astro.build/en/reference/api-reference).

@flint marsh I have this in my pages/index.astro, how to access them
export function getStaticPaths() {
return [{ params: { platform: "ios" } }, { params: { platform: "android" } }];
}

Let me check the knowledge base for you. One moment! :books:
In Astro, you can access the parameters from the URL using the Astro.params object. This object contains the values of dynamic route segments matched for the request.
In your case, you can access the platform parameter from the URL as follows:
---
export function getStaticPaths() {
return [{ params: { platform: "ios" } }, { params: { platform: "android" } }];
}
const { platform } = Astro.params;
---
<h1>{platform}</h1>
In this example, Astro.params is used to get the platform parameter from the URL. The getStaticPaths function is used to define the possible values for platform.
However, please note that getStaticPaths is used for dynamic routes, and it seems like you're trying to use it in a static route (index.astro). Dynamic routes in Astro are defined by including parameters in the filename, like [platform].astro.
