Versioning APIs and Managing Code

Problem We often face the issue like the integration was broken since there is a change on the other side of software or API. We want the software integrations to work regardless of changes in the interfaces. Backward compatibility is very crucial for every software should consider seriously. Backward compatibility is a property of an operating system, software, real-world product, or technology that allows for interoperability with an older legacy system, or with input designed for such a system.   Modifying a system in a way that does not allow backward compatibility is sometimes called "breaking" backward compatibility. Such breaking usually incurs various types of costs, such as switching cost. The software is considered stable when its  API  that is used to invoke functions is stable across different versions. Any customers do not want to integrate with a software that keep changing its interface. With microservices architecture, APIs are the key integration poin...

Handle Multipart Contents in Asp.Net Core

Handle Multipart Contents in Asp.Net Core Introduction When we program a web API in ASP.Net core we usually we have the Content-Type header as ‘application/json’ if it is a REST API. Assume a scenario where we need to pass an image along with description about the image or metadata. We can either pass that information in query parameters or in headers, but query parameters or header has limited in size. If the metadata is a json object, then query parameters or header is not a best place to pass. How about sending both the json and binary image within the body itself. There is a Content-Type ‘multipart/mixed’ in HTTP protocol is where we can achieve this. This article shows you how to pass both the json data and the binary in the same http request. Content-Type=multipart/mixed Header In the below example I will show how to use http header content-type as ‘multipart/mixed.’ The purpose of the Content-Type field is to describe the data contained in the body fully enough that the ...
