Dapr Client examples
The following examples will show you how to:
- Invoke services
- Publish events
- Use the state store to get, set, and delete data
Prerequisites
Running the Sample
To run the sample locally run this command in DaprClient directory:
dapr run --app-id DaprClient -- dotnet run <sample number>
Running the following command will output a list of the samples included.
dapr run --app-id DaprClient -- dotnet run
Press Ctrl+C to exit, and then run the command again and provide a sample number to run the samples.
For example run this command to run the 0th sample from the list produced earlier.
dapr run --app-id DaprClient -- dotnet run 0
Samples that use HTTP-based service invocation will require running the RoutingService.
Samples that use gRPC-based service invocation will require running GrpcService.
Invoking Services
See: InvokeServiceHttpClientExample.cs for an example of using HttpClient to invoke another service through Dapr.
See: InvokeServiceHttpExample.cs for an example using the DaprClient to invoke another service through Dapr.
See: InvokeServiceGrpcExample.cs for an example using the DaprClient to invoke a service using gRPC through Dapr.
Publishing Pub/Sub Events
See: PublishEventExample.cs for an example using the DaprClient to publish a pub/sub event.
Working with the State Store
See: StateStoreExample.cs for an example of using DaprClient for basic state store operations like get, set, and delete.
See: StateStoreETagsExample.cs for an example of using DaprClient for optimistic concurrency control with the state store.
See: StateStoreTransactionsExample.cs for an example of using DaprClient for transactional state store operations that affect multiple keys.
