Validating package payload

create a new order, send an invoice, schedule a delivery and so on.

As you can see, there are many approaches to input validation.

Recently, during a pair programming session, I had a really interesting discussion.

We talked about validating incoming payload which was basically a client’s input in a JSON format.

For more information on the upcoming change, we invite you to read our blog post.

JSONLint is a validator and reformatter for JSON, a lightweight data-interchange format.

Copy and paste, directly type, or input a URL in the editor above and let JSONLint tidy and validate your messy JSON code. As a solution, either use direct URL input, or make sure your content's newlines match the architecture your system expects! Thanks to Douglas Crockford of JSON and JS Lint, and Zach Carter, who built a pure Java Script implementation.

You can download the JSONLint source code on Git Hub.

Here is the list of parameters that apply to Make Appx pack, Make Appx unpack, Make Appx bundle, Make Appx unbundle, Make Appx encrypt, or Make Appx decrypt.

Our request hit a controller so we can build this from from received parameters.

Having a proper Form Object we are sure that we will provide valid parameters in any place In this way, we delegate input validation to a particular service.

Here are the command-line parameters that apply specifically to each command: Make Appx pack [h] Creates a package.

Make Appx unbundle [pfn] Unpacks all packages to a subdirectory under the specified output path, named after the bundle full name.

I believe there’s no silver bullet for that because all depends on the context.
