Hello,

I'm following along the tutorial that demonstrates how to create a simple messaging app. Everything has been going great, but I have bumped into a couple of problems/confusion on this page:

Quote

https://github.com/crypti/crypti-dapps-docs/blob/master/MessagingDapp.md

Specifically, where does the code go that is described under "After our validation passes, we need to generate a key pair. To do this, we use modules.api.crypto.keypair". Is it in the callback of Message.prototype.add like this:

Code:

Message.prototype.add = function (cb, query) {
// Validate query object
library.validator.validate(query, {
type: "object",
properties: {
recipientId: {
type: "string",
minLength: 1,
maxLength: 21
},
secret: {
type: "string",
minLength: 1,
maxLength: 100
},
message: {
type: "string",
minLength: 1,
maxLength: 160
}
}
}, function (err) {
// If error exists, execute callback with error as first argument
if (err) {
return cb(err[0].message);
}

var keypair = modules.api.crypto.keypair(query.secret);
modules.blockchain.accounts.getAccount({
publicKey: keypair.publicKey.toString('hex')
}, function (err, account) {
// If error occurs, call cb with error argument
if (err) {
return cb(err);
}

// Create new transaction
try {
var transaction = library.modules.logic.transaction.create({
type: self.type,
message: query.message,
recipientId: query.recipientId,
sender: account,
keypair: keypair
});
} catch (e) {
// Catch error if something goes wrong
return setImmediate(cb, e.toString());
}

// Send transaction for processing
modules.blockchain.transactions.processUnconfirmedTransaction(transaction, cb);
});

});
}

A second issue I am having is with the command:

Code:

crypti-cli dapps --deposit

. I get the following error:

Quote

{ [Error: connect ECONNREFUSED]
code: 'ECONNREFUSED',
errno: 'ECONNREFUSED',
syscall: 'connect' } undefined
Error: connect ECONNREFUSED

Is this a port/firewall issue or something else?

Finally, I am getting an error when trying to run the PUT for the first message:

Code:

curl -XPUT -H "Content-type: application/json" -d '{
"recipientId": "58191895912485C",
"message": "Hello, world!",
"secret": "mysecret"
}' 'http://[my_domain_and_port]/api/dapps/[dappid]/api/messages/add'

Error:

Quote

Cannot PUT /dapps/1719096962757412325/api/messages/add

Does the recipientId have to be something specific, or can it be any string? Any idea how to debug that?

Thanks!

Baz

1. Recipient must be Crypti address or your address.
2.

Did you restarted crypti when updated code? Did you have Crypti enabled when trying deposit? And did you added api calls to routes.json file? Thanks for answers. Meanwhile i will try it.
