javascript - How can I use Joi to sanitize the query parameter for hapi? -

i wondering if can use joi automatically sanitize query parameter instead of manually doing that?

this have done route.

var querystring = require('querystring');  function datetostring(date) {   return moment(new date(querystring.unescape(date))).toisostring(); }  function posts(request, reply) {   request.query.from = datetostring(request.query.from); } 

and joi schema.

var toppostsconfig = {   description: 'top posts',   plugins: {     'hapi-swagger': {         order: 1     }   },   validate: {     query: {        form: joi.date().iso().optional().default(moment().subtract(2, 'day').utc().format()).description('start date query')     }   } }  {   method: 'get',   path: '/posts',   handler: posts,   config: toppostsconfig } 

just wondering if joi has special method auto sanitize query parameter unescaped characters?

edit: request comes in 2016-02-05t20%3a26%3a34.916z escaped browser. thinking if joi can unescape automatically don't have manually.

first off have typo on field validating - "form" instead of "from".

joi should receive decoded url query. it's easy check replacing joi query validation object function , inspecting value:

server.route({   method: 'get',   path: '/posts',   handler: (req, reply) => {     reply(req.query);   },   config: {     description: 'top posts',     validate: {       query: (value, options, next) => {         console.log(value);         next(null, value);       },     },   }, }); 

when fix typo in example works expected.

if want additional data processing can use function form of validation , using joi.validate() function body.
