Synchronous server-side connection to the UnityBase instance. To be used only inside UnityBase. For nodeJS & browser use asynchronous UBConnection class from @unitybase/ub-pub package.

The most used method is SyncConnection.query - a authorized request to ubql endpoint.

  
      const SyncConnection = require('@unitybase/base').SyncConnection
const conn = new SyncConnection({URL: 'http://localhost:888'})
conn.onRequestAuthParams = function(){ return {authSchema: 'UB', login: 'admin', password: 'admin'} }
const domain = conn.getDomainInfo();
if (domain.has('my_entity')){
 ..
}
  

# new SyncConnection (optionsObject)

Arguments:

Members

# appConfig : Object instance

AdminUI settings

# appName : String instance

Name of UnityBase application

# authMethods : Array.<string> instance

Possible server authentication method

# authNeed : Boolean instance

Is UnityBase server require authorization

# clientRequest : ClientRequest instance

Internal instance of HTTP client

# encryptContent : Boolean instance

Is server require content encryption

# onRequestAuthParams : function instance

Callback for resolving user credential. Take a SyncConnection as a parameter, must return authorization parameters object:

 {authSchema: authType, login: login, password: password, [apiKey: ]}

For a internal usage (requests from a locahost or other systems, etc.) and in case authShema == 'UB' it is possible to pass a apiKey instead of a password. apiKey is actually a uba_user.uPasswordHashHexa content

# queryMethod : string instance

Endpoint name for query (runList before 1.12, ubql after 1.12)

# serverCertificate : Boolean instance

base64 encoded server certificate used for cryptographic operation

# servicePath : String instance

Root path to all application-level method

# sessionKeyLifeTime : Number instance

Lifetime (in second) of session encryption

# UBQLv2 instance

Server support UBQL v2 (value instead of values)

Name Type Description
UBQLv2 Boolean

# _domain : UBDomain inner

Methods

# addNew (ubqubRequest) → * instance

Execute addnew method: add method 'addnew' to ubq query (if req.method not already set)

If ubq.fieldList contain only ID return generated ID, otherwise return array of attribute values passed to fieldList. If no field list passed at all - return response.resultData (null usually).

Arguments:
  
      const testRole = conn.addNew({
    entity: 'uba_role',
    fieldList: ['ID', 'name', 'allowedAppMethods'],
    execParams: {
      name: 'testRole1',
      allowedAppMethods: 'runList'
    }
  })
 console.log(testRole) //[3000000000200,"testRole1","runList"]

 const testRoleID = conn.addNew({
    entity: 'uba_role',
    fieldList: ['ID']
  })
 console.log(testRoleID) //3000000000200
  

# addNewAsObject (ubqubRequest, fieldAliasesoptObject.<string, string>) → Object instance

Run UBQL command with addnew method

In case fieldList is passed - result will contains new values for attributes specified in fieldList as Object, otherwise - null

In opposite to addNew method values in result are PARSED based on Domain (as in AsyncConnection) - so values for boolean attributes is true/false, date is typeof Date etc.

Arguments:
  • ubq: ubRequest
  • fieldAliases: Object.<string, string>

    Optional object to change attribute names during transform array to object. Keys are original names, values - new names

  
      const newRole = conn.addNewAsObject({
  entity: 'uba_role',
  fieldList: ['ID', 'name', 'allowedAppMethods'],
  execParams: {
      name: 'testRole61',
      allowedAppMethods: 'runList'
  }
})
 console.log(newRole) // {ID: 332462911062017, name: 'testRole1', allowedAppMethods: 'runList'}
