Validate non-string parameters
Opened this issue · 2 comments
Since Koa's ctx.query object has every query parameter set to a string value, this middleware is throwing an error when I attempt to validate a query parameter that should be an integer. For instance, if my URI has a query parameter like ?limit=5 and then I do ctx.verifyParams({ limit: 'int' }); an error is thrown because ctx.query is { limit: '5' }. Is there a way to tell the middleware to attempt to coerce the query parameter's value to the expected type from a string before the validation occurs or a separate middleware that would perform this?
parameter is a strict validation check module and cannot validate a field if you don't cast it to the correct type
// Example code:
if (ctx.query.hasOwnProperty("limit")) {
if (ctx.query.limit != undefined) {
ctx.query.limit = parseInt(ctx.query.limit);
} else {
delete ctx.query.limit;
}
}Hi all,
Parameter class now has a convert option which is able to cast string into other types.
Maybe we can add an argument to let user decide whether to use it or not.
