This component provides the ability to run rhai scripts to process http requests in tide. Currently it only supprts modifying the messages but additional features such as a http client are being considered.
$ cargo add tide-rhai
Create a tide server that points to a directory containing rhai scripts.
```rust use tide_rhai::RhaiDir;
async fn main() -> Result<(), std::io::Error> {
tide::log::start();
let mut app = tide::new();
app.at("/")
.get(RhaiDir::new("/", "./").unwrap());
app.listen("127.0.0.1:8080").await?;
Ok(())
}
``
The first parameter for new is the prefix and should be mapped to theat` parameter.
The second is the folder with the rhai scripts in
Creat a rhai script called headers.rhai that selects a header and returns it in a JSON Message. Note it doesn't have to be called .rhai but VS Code has suppport for that file extention.
rust
let obj = #{};
obj.message = "Is this acceptable?" + ctx.headers["accept"];
obj
Here we are using the headers property of the context object. If this was a POST then the ctx object would also contain a data property with the JSON that has been sent to the server.
When you now run to https://localhost:8080/headers.rhai you should see the following:
json
{"message":"Is this acceptable?text/html,application/xhtml+xml,application/xml;q=0.9,
image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9"}
This example can also be ran by cloning this repository and running
bash
$ cargo run --example samples
Then browse to:
http://localhost:8080/helloworld.rhai http://localhost:8080/headers.rhai http://localhost:8080/fetch.rhai
