An easy way to validate Go request

<p>When building REST API or web applications using Go, an essential part is to validate the incoming request data. I have worked in some small and medium project in Golang, most of them are micro-services, providing restful API. I have used a different way to validate incoming data. Let&#39;s start with particular one that I use frequently. For validating application/json or text/plain request, first I build a struct type of that particular request and add a validate method on the struct. Let&#39;s see an example <a href="https://medium.com/@thedevsaddam/an-easy-way-to-validate-go-request-c15182fd11b1">Read full post here</a></p> <hr/>**评论：**<br/><br/>arp242: <pre><p>You keep posting this literally every week: <a href="https://www.reddit.com/r/golang/comments/711qdw/validate_input_in_golang_easily/">one</a>, <a href="https://www.reddit.com/r/golang/comments/71wm45/validate_golang_request_data_with_simple_rules/">two</a>, <a href="https://www.reddit.com/r/golang/comments/75yt2x/golang_request_validation_package_update/">three</a>, and I&#39;m almost certain there was a fourth (now deleted) post as well.</p> <p>I&#39;m sure your library is great and all, but don&#39;t think we need to know about it every week...</p></pre>thedevsaddam: <pre><p>Does it feel allergic to you? And THIS is a post I am sharing not just the link. Don&#39;t tell people to stop contributing open source, to stop contributong on that project. You don&#39;t contribute that doesn&#39;t mean others can&#39;t do it. and don&#39;t take it personally. </p></pre>ZetaHunter: <pre><p>I just use <a href="https://github.com/go-chi/render" rel="nofollow">https://github.com/go-chi/render</a> which provides more or less generic Binder interface in which you can do your validation code.</p></pre>manifold360: <pre><p>I use <a href="https://github.com/go-openapi" rel="nofollow">OpenAPI</a> (aka swagger) to define the schema, publish the schema, and validate the request with the schema. It is the best solution I have seen in a long time.</p> <p>I also validate on the JS client-side against the published api specs.</p></pre>
