Struct async_fcgi::client::connection::Connection

pub struct Connection { /* private fields */ }

Single transport connection to a FCGI application

Can multiplex max_req_per_con simultaneous request streams

Implementations

impl Connection

pub async fn connect( addr: &Addr, max_req_per_con: u16 ) -> Result<Connection, Box<dyn Error>>

Connect to a peer with MultiHeaderStrategy::OnlyFirst & HeaderMultilineStrategy::Ignore.

pub async fn connect_with_strategy( addr: &Addr, max_req_per_con: u16, header_mul: MultiHeaderStrategy, header_nl: HeaderMultilineStrategy ) -> Result<Connection, Box<dyn Error>>

Connect to a peer

pub fn is_ready(&self) -> bool

true if the next call to forward does not need to wait for the end of some previous request

pub async fn close(self) -> Result<(), IoError>

pub async fn forward<B, I, P1, P2>( &self, req: Request<B>, dyn_headers: I ) -> Result<Response<impl Body<Data = Bytes, Error = IoError>>, IoError>where B: Body + Unpin, I: IntoIterator<Item = (P1, P2)>, P1: Buf, P2: Buf,

Forwards an HTTP request to a FGCI Application

let req = Request::get("/test?lol=1").header("Accept", "text/html").body(Empty::<Bytes>::new())?;
let mut params = [(
    &b"SCRIPT_FILENAME"[..],
    &b"/home/daniel/Public/test.php"[..]
)];
let mut res = fcgi_con.forward(req, params).await?;

Fills QUERY_STRING, REQUEST_METHOD, CONTENT_TYPE and CONTENT_LENGTH from the corresponding values in the Request. Headers from the Request will be added with the HTTP_ prefix. (CGI/1.1 4.1.18)

Additional Params might be expected from the application (at least the url path):
