Hi,
I nested the subsequest org.getVault calls inside the callback of first and below code is working for me as a solution here.
var http = require('http');
var apigee = require('apigee-access');
var svr = http.createServer(function(req, resp) {
var orgVault = apigee.getVault('SampleVault', 'environment');
//Call to get the HostURL
orgVault.get('HostURL',function(err, HostURL) {
if(err){
resp.end('Failed to get HostURL');
}
else {
apigee.setVariable(req,"HostURL",HostURL);
console.log('HostURL',HostURL);
// Next call to get the TokenURL
orgVault.get('TokenURL',function(err, TokenURL) {
if(err){
resp.end('Failed to get TokenURL');
}
else {
apigee.setVariable(req,"TokenURL",TokenURL);
console.log('TokenURL',TokenURL);
// Next call to get the CallURL
orgVault.get('CallURL',function(err, CallURL) {
if(err){
resp.end('Failed to get CallURL');
}
else {
apigee.setVariable(req,"CallURL",CallURL);
console.log('CallURL',CallURL);
// Next call to get the Username
orgVault.get('Username',function(err, Username) {
if(err){
resp.end('Failed to get Username');
}
else {
apigee.setVariable(req,"Username",Username);
console.log('Username',Username);
// Next call to get the Password
orgVault.get('Password',function(err, Password) {
if(err){
resp.end('Failed to get Password');
}
else {
apigee.setVariable(req,"Password",Password);
console.log('Password',Password);
resp.end('All Calls were successful');
}
});
}
});
}
});
}
}):
}
});
});
svr.listen(9000, function() {
console.log('The server is listening on port 9000');
});
This is because there is no other logic in node.js than callback to check if the call got completed or not.
Using 'serial' execution model of express will be a overkill here as we are not doing anything but fetching values from vault.
Please let me know if this works fine or need any modifications/changes to make it better.
Thanks,
Santosh
