Python : Converting unicode logs of dict into valid json format

While debugging, programmer goes through logs to grab request payload. The issue is payload is wrapped with u for unicode, ‘ and True and False and None which are python standards however fails to pass json validation.

Hence to use them, we need to convert the unicoded python dict into valid json to do crul call, for the same here is the simple trick :

{u’a’: u’aValue’, u’b’: u’bValue’, u’c’: u’cValue’} is a dictionary which you are calling as unicode json. Now, in your language if you want a regular json from this then just do something like this:

x={u'a': u'aValue', u'b': u'bValue', u'c': u'cValue'}
y=json.dumps(x)
print y

The output will be {“a”: “aValue”, “c”: “cValue”, “b”: “bValue”}

This will remove all u, convert False into false, True into true, None into null and convert ‘ into ”   🙂

MongoDb : Add user to DB

use myDb
db.createUser(
   {
     user: "accountUser",
     pwd: "password",
     roles: [ "readWrite", "dbAdmin" ]
   }
)

Login with admin role, use your db and create user with role.

Mongodb – can’t login via -u root -p bitnami

Are you trying to login like this?

mongo admin --username root --password YOUR_PASSWORD

where YOUR_PASSWORD is the one you can see in your AWS system log:

Setting Bitnami application password to 'YOUR_PASSWORD'

If this doesn’t work, you can also try resetting MongoDB password:

Nodejs : Simple get call using http node module

var http = require('http');

var options = {
  host: 'example.com',
  port: 80,
  path: '/foo.html'
};

http.get(options, function(resp){
  resp.on('data', function(chunk){
    //do something with chunk
  });
}).on("error", function(e){
  console.log("Got error: " + e.message);
});

MongoDb : Case in-sensative search using pymongo

As we all know Json is case sensitive and so is MongoDB, hence searching same name which got save in different case might not return any result. The solution is to do case in-sensative search.

Below is the example of pymongo

db.users.find_one({'name': re.compile(username, re.IGNORECASE)})
