[−][src]Struct azure_functions::bindings::SignalRMessage
Represents the SignalR message output binding.
The following binding attributes are supported:
Name | Description |
---|---|
name | The name of the parameter being bound. |
hub_name | The name of the SignalR hub that will receive the message. |
connection | The name of the app setting that contains the SignalR Service connection string. Defaults to AzureSignalRConnectionString . |
Examples
This example implements an HTTP-triggered Azure Function that returns a SignalRMessage binding:
use azure_functions::{ bindings::{HttpRequest, SignalRMessage}, func, }; use serde_json::{to_value, Value}; #[func] #[binding(name = "req", auth_level = "anonymous", methods = "post")] #[binding(name = "$return", hub_name = "chat", connection = "myconnection")] pub fn send_message(req: HttpRequest) -> SignalRMessage { SignalRMessage { user_id: req.query_params().get("user").map(|v| v.to_owned()), group_name: req.query_params().get("group").map(|v| v.to_owned()), target: "newMessage".to_owned(), arguments: vec![req.query_params().get("message").map_or(Value::Null, |v| to_value(v).unwrap())], } }
Fields
user_id: Option<String>
The optional user id to send the message to.
group_name: Option<String>
The optional group name to send the message to.
target: String
The target method name to invoke on each SignalR client.
arguments: Vec<Value>
The arguments to pass to the target method.
