In my previous blog post about LocalStack S3 setup I’ve included a hardcoded delay of 5 seconds before actually calling AWS SDK. This gives enough time when waiting LocalStack to start and be ready to accept incoming requests. However, what is actually enough?
If you use AWS S3 and don’t want to use the actual bucket for one or another reason for your local development, you’ve probably come across LocalStack S3 mock for this. Especially, if you are running your apps or integration tests in Docker.
Chakram has a lot of examples of using JSON requests, however I needed a working solution for chakram multipart file upload and authenticate using Authorization header.
A quick example to illustrate an implementation of a custom Unauthorized response body in ASP.NET Core 2.0. The implementation is based on the AuthorizeFilter from Microsoft MVC framework.
A quick working example of Covariance and Contravariance in generics for a reference of when in and out C# keywords can be used.
Recently I’ve run into an ASP.NET Core MVC bug when an HTTP request with multipart content-type and empty body would cause an unhanded IOException exception to be thrown in MVC framework. However, when sending an invalid request I’d expect to receive a 400 error response code.
In this blog post I will share my experience of assembling, programming, and testing Robi-kun. Robi-kun is a Japanese toy robot which comes in parts from 70 magazines subscription. I’ve picked up an existing and half-done assembly, tested the assembled components, and completed the assembly to bring the robot to life :)
I was setting up Amazon SQS client locally, and received No RegionEndpoint or ServiceURL configured exception. My goal was to load all AWS config values from environment variables together with a temporary session token, however I will go trough config file option as well. Apparently region value was not picked up by the Amazon SQS client.
This blog post shows a quick example of implementing custom authentication in .NET Core 2.0 to secure your Web API. And in most cases you do want to secure your Web APIs, even though they were internal (micro)services only. If you don’t have a proper Identity provider e. g. Identity Server in place, and just need a quick solution, then a simple option is to validate Authorization header against a hardcoded value.
If you’ve ever tried to change a default value of a SQL constraint you’ve probably noticed that you have to drop the constraint, and then re-create the constraint with a new default value. However, what if you found an auto-named SQL constraint, and you started wondering how your SQL script will work across different environments with different databases…
