CreateBlog: Client Implementation

The CreateBlog method on the client side is responsible for sending a new blog post to the server and handling the response. Here’s a detailed implementation:

1. Create a Client Stub

Create a gRPC client stub using the generated Java classes.

Java

BlogServiceGrpc.BlogServiceBlockingStub stub = BlogServiceGrpc.newBlockingStub(channel);

2. Create a BlogPost Object

Create a BlogPost object with the desired title and content.

Java

BlogPost blogPost = BlogPost.newBuilder()
        .setTitle("My First Blog Post")
        .setContent("This is the content of my blog post.")
        .build();

3. Call the CreateBlog Method

Call the CreateBlog method on the client stub, passing the BlogPost object as an argument.

Java

BlogPost response = stub.createBlogPost(blogPost);

4. Handle the Response

Handle the response from the server. If the request was successful, the response will contain the created blog post.

Java

if (response.hasId()) {
    System.out.println("Blog post created successfully. ID: " + response.getId());
} else {
    System.err.println("Error creating blog post: " + response.getMessage());
}

Complete Example

Java

public class BlogClient {
    public static void main(String[] args) throws IOException, InterruptedException {
        ManagedChannel channel = ManagedChannelBuilder.forAddress("localhost", 50051)   
                .usePlaintext()
                .build();

        BlogServiceGrpc.BlogServiceBlockingStub stub = BlogServiceGrpc.newBlockingStub(channel);   

        BlogPost blogPost = BlogPost.newBuilder()
                .setTitle("My First Blog Post")
                .setContent("This is the content of my blog post.")
                .build();

        BlogPost response = stub.createBlogPost(blogPost);

        if (response.hasId()) {
            System.out.println("Blog post created successfully. ID: " + response.getId());
        } else {
            System.err.println("Error creating blog post: " + response.getMessage());
        }

        channel.shutdownNow().awaitTermination(5, TimeUnit.SECONDS);
    }
}
