Hi @elder dock. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
In Astro, you can't directly set the body of a request using Astro.request.body.set(). Instead, you can pass data to the body of a request by using the fetch function. Here's an example of how you can do it:
---
const data = { restaurant_id: 1 };
const res = await fetch('/api/endpoint', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify(data)
});
---
In this example, fetch is used to make a POST request to the /api/endpoint. The data to be sent in the body of the request is defined in the data object, which is then converted to a JSON string using JSON.stringify(data) and passed to the body property of the fetch options.
Please note that the endpoint /api/endpoint is just a placeholder, you should replace it with your actual API endpoint.
Also, remember to handle the response (res) appropriately, for example by converting it to JSON with await res.json() if the API returns JSON data.

@fluid vigil but for GET() api endpoint, i can do Astro.request.headers.set, so I wonder if there's any way to set the body for POST() api endpoint?

Let me check the knowledge base for you. One moment! :books:
In Astro, setting the body for a POST request is done differently than setting headers. For a POST request, you typically want to send data in the body of the request. This is done by passing an object to the body property of the fetch options, as shown in the previous example.
However, if you're trying to set the body in an Astro API endpoint, you can do so by returning an object from your endpoint function with a body property. Here's an example:
export const post: APIRoute = async ({ request, url }) => {
const body = await request.json();
// ... do something with the body data ...
return {
status: 200,
headers: {
'content-type': 'application/json',
},
body: JSON.stringify({ key: 'value' }), // This is the response body
};
};
In this example, the post function is an Astro API endpoint that receives a request and returns a response. The response body is set by returning an object with a body property.
Please note that the body property should be a string, so if you want to return a JavaScript object, you need to convert it to a JSON string using JSON.stringify().
