固定和ajv模式验证

Question

I am trying to validate the querystring parameter 'hccid' as shown below. Seems like the validation is not working for me. Can some one see what I am missing?

const fastify = require('fastify')({
  ajv: {
        removeAdditional: true,
        useDefaults:      true,
        coerceTypes:      true
    }
});


const schema = {
    querystring: {
       hccid: { type: 'string' }
    }
};

// Declare a route
 fastify.get('/hello', {schema}, function (request, reply) {
    const hccid = request.query.hccid;
    reply.send({ hello: 'world' })
});

// Run the server!
fastify.listen(3000, function (err) {
if (err) throw err
  console.log(`server listening on ${fastify.server.address().port}`)
});

So with that code, I should get a schema validation exception when I call the service with a total new queryparam abc just like I shown below

http://localhost:3000/hello?abc=1

but there was no error. I got the response back {"hello":"world"}

I also tried removing the queryparam all together http://localhost:3000/hello

and I still got {"hello":"world"}

so obviously the validation is not working. What is missing in my code? any help would be appreciated.

Answer 1

this schema structure solved my problem. Just in case if someone wants to check it out if they run into similar issue.

const querySchema = {
    schema: {
       querystring: {
         type: 'object',
           properties: {
             hccid: {
               type: 'string'
             }
         },
       required: ['hccid']
     }
  }
}
