To create an AWS Lambda function that calls a REST endpoint, you can use the HttpClient
class in the .NET Framework to send an HTTP request to the endpoint. Here’s an example of how you can do this in C#:
Copy codeusing System.Net.Http;
public class LambdaFunction
{
public async Task<string> FunctionHandler(object input, ILambdaContext context)
{
using (HttpClient client = new HttpClient())
{
// Set the base address and the headers for the request
client.BaseAddress = new Uri("http://example.com");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
// Send the request and wait for the response
HttpResponseMessage response = await client.GetAsync("/endpoint");
response.EnsureSuccessStatusCode();
string responseContent = await response.Content.ReadAsStringAsync();
// Return the response content
return responseContent;
}
}
}
This code uses the HttpClient
class to send an HTTP GET request to the specified endpoint and retrieves the response content as a string. You can modify the request and the response handling as needed to meet the requirements of your application.
I hope this helps! Let me know if you have any other questions or if there’s anything else I can do to assist.
