Azure Cosmos DB
To use Azure Cosmos DB in serverless mode, choose Serverless as the Capacity mode when creating your account.
1.Register binding extensions
dotnet add package Microsoft.Azure.WebJobs.Extensions.CosmosDB --version 3.0.10
2.Add an output binding
[CosmosDB(databaseName: "my-database", collectionName: "my-container",
ConnectionStringSetting = "CosmosDbConnectionString"
)]IAsyncCollector<dynamic> documentsOut,
3.Add code that uses the output binding
[FunctionName("HttpExample")]
public static async Task<IActionResult> Run(HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
[CosmosDB(
databaseName: "my-database",
collectionName: "my-container",
ConnectionStringSetting = "CosmosDbConnectionString")]IAsyncCollector<dynamic> documentsOut,ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
string name = req.Query["name"];
string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
dynamic data = JsonConvert.DeserializeObject(requestBody);
name = name ?? data?.name;
if (!string.IsNullOrEmpty(name))
{
// Add a JSON document to the output container.
await documentsOut.AddAsync(new
{
// create a random ID
id = System.Guid.NewGuid().ToString(),
name = name
});
}
string responseMessage = string.IsNullOrEmpty(name)
? "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
: $"Hello, {name}. This HTTP triggered function executed successfully.";
return new OkObjectResult(responseMessage);
}
