Developing Mapping Scripts

Code Rule

OneAccess imposes several restrictions on mapping scripts, including disabling Java class, limiting CPU usage time, and restricting memory usage, the script format, and the use of certain functions.

• Do not use Java class.

  If the following code is used:

  var File = Java.type('java.io.File'); File;

  The following exception will be thrown:

  java.lang.ClassNotFoundException: java.io.File

• Limit the CPU usage time.

  By default, the execution time is limited to 1 second. If the execution time exceeds this limit, an exception will be thrown.

  If the following code is used:

  do{}while(true);

  The following exception will be thrown:

  ScriptCPUAbuseException

• Limit the memory usage.

  The default size is 10 MB. If the size exceeds this limit, an exception will be thrown.

  If the following code is used:

  var o={},i=0; while (true) {o[i++] = 'abc'}

  The following exception will be thrown:

  ScriptMemoryAbuseException

• Restrict the script format.

  To ensure proper script formatting, the if, while, and for statements must be enclosed in braces. Failure to do so may result in format errors.

  If the following code is used:

  var o={},i=0; while (true) o[i++] = 'abc';

  The following exception will be thrown:

  BracesException

• Restrict the use of certain functions.

  The following functions cannot be used in the code. If they are included, they will have no effect.

  print 
  echo 
  quit 
  exit
  readFully 
  readLine 
  load
  loadWithNewGlobal

Example Scripts

• User attributes

  The user object can be used in the script and contains all user attributes. The specific attributes are subject to the attribute code in the attribute definition. For details about managing user attributes, see Managing User Attributes. For details about managing account attributes, see 9.

  

  • Example 1: Map the user registration time:

    var createdAt = user.createdAt; 
    var date =new Date(createdAt); 
    date.toISOString();

  • Example 2: Map the mobile phone number of a user and hide the four digits in the middle:

    var mobile = user.mobile;
    var result = "";
    if(mobile.length == 15) {
      result = mobile.slice(0,7) + "****" + mobile.slice(-4);
    }
    result;

  • Example 3: Generate a user email address based on the username:

    var username = user.userName; 
    username.toLowerCase()+"@huaweicloud.com";

• Organization attributes

  The organization object can be used in the script and contains all the attributes of the organization.

  • Example 1: Map an organization name.

    var orgName = organization.name;
    orgName.toString();

  • Example 2: Map organization code.

    var orgCode = organization.code;
    orgCode.toString();

  • Example 3: Map an organization ID.

    var id= organization.id;
    id.toString();

• System attributes

  Obtain system attributes, such as date.

  Example: Map the time for tomorrow:

  var date =new Date();
  date.setDate(date.getDate()+1); 
  date.toISOString();
