This method interacts with information from the current request. The request may come from:
|
|
|
|
1. The initial SSR render if this method called from a [`Component`](dioxus_lib::prelude::component) or a [`server`](crate) function that is called during the initial render
|
|
|
|
```rust
|
|
# use dioxus::prelude::*;
|
|
#[component]
|
|
fn PrintHtmlRequestInfo() -> Element {
|
|
// The server context only exists on the server, so we need to put it behind a server_only! config
|
|
server_only! {
|
|
// Since we are calling this from a component, the server context that is returned will be from
|
|
// the html request for ssr rendering
|
|
let context = server_context();
|
|
let request_parts = context.request_parts();
|
|
println!("headers are {:?}", request_parts.headers);
|
|
}
|
|
rsx! {}
|
|
}
|
|
```
|
|
|
|
2. A request to a [`server`](crate) function called directly from the client (either on desktop/mobile or on the web frontend after the initial render)
|
|
|
|
```rust
|
|
# use dioxus::prelude::*;
|
|
#[server]
|
|
async fn read_headers() -> ServerFnResult {
|
|
// Since we are calling this from a server function, the server context that is may be from the
|
|
// initial request or a request from the client
|
|
let context = server_context();
|
|
let request_parts = context.request_parts();
|
|
println!("headers are {:?}", request_parts.headers);
|
|
Ok(())
|
|
}
|
|
|
|
#[component]
|
|
fn CallServerFunction() -> Element {
|
|
rsx! {
|
|
button {
|
|
// If you click the button, the server function will be called and the server context will be
|
|
// from the client request
|
|
onclick: move |_| async {
|
|
_ = read_headers().await
|
|
},
|
|
"Call server function"
|
|
}
|
|
}
|
|
}
|
|
```
