Validating code

The validation constraints can be declared in JSON and shared between clients and the server. One thing that is a bit unorthodox is that most validators will consider undefined values (,) valid values.

So for example adding a constraint of at least 6 characters will be like saying If the attribute is given it must be at least 6 characters.

Unless otherwise specified you can always specify the message option to customize the message returned if the validator doesn't pass.

Just remember to not include the attribute name since it's automatically prepended to the error message.

access_token i get error 'Error validating verification code'. r=site/oauth2 but i need passing some params can somebody help me? id=70855 but nothing work for me There are presently (as of March 2011) undocumented requirements regarding what makes a valid redirect_uri.

You can tell to use any A compatible promise implemention like this: There are already many validation libraries out there today but most of them are very tightly coupled to a language or framework.

The goal of is to provide a cross framework and cross language way of validating data.

If you want to use async validation you need to use a runtime that supports Promises.This differs from example Ruby on Rails where validators instead have the option.I find it quite common that you want to have constraints on an optional attribute.The project can be found on Git Hub where you can also find our issue tracker.There is also a Travis project used for testing, a Coveralls project used to code coverage as well as the annotated source.is an open source component of Wrapp and is licensed under the MIT license.There are no required external dependencies at all!Second, you cannot use many special characters in the redirect_uri.A lot of discussion rages whether parameters can be passed at all.They can, you're limited which characters are valid but no one has published a list that I know. There are a lot of programmers passing along misinformation that a simple solution is to pass type=client_cred. I knew for a fact that my URLs were the same because I used a class with the same $var, but I kept getting the 400 response and that error in the JSON response.Traditional methods like url/html encoding will fail because percent(%) is not valid. This may limit your access to some of the permissions you requested in your authorization. The only thing I did was change my redirect_uri from: Part of the information given by Aaron Wheeler is incorrect.


  1. On-the-fly validation is available for all Web content files and is performed as you edit the file. However, this form of code validation is rather soft, that is, not all.
