Chapter 6 retrieving Blog Data

Retrieving a Single, Full Blog Post

Now that we can return a list of summaries, we also need to return a single blog post to display in full. For that, we are going to reuse the same Azure Function file but add a new method which will have a modified route.

1. Copy the code from Code 6-12 underneath the existing function.

Code 6-12. Get Single Blog Post Function

[FunctionName($"{nameof(BlogPosts)}_GetId")]

public static IActionResult GetBlogPost(

[HttpTrigger(AuthorizationLevel.Anonymous, "get",

Route = "blogposts/{author}/{id}")]

HttpRequest req,

[CosmosDB("SwaBlog", "BlogContainer",

Connection = "CosmosDbConnectionString",

SqlQuery = @"SELECT

c.id,

c.Title,

c.Author,

c.PublishedDate,

c.BlogPostMarkdown,

c.Status,

c.Tags

FROM c

WHERE c.id = {id} and c.Author={author}")]

IEnumerable<BlogPost> blogposts,

ILogger log)

{

if (blogposts.ToArray().Length == 0)

{

return new NotFoundResult();

}

return new OkObjectResult(blogposts.First());

}
