What's the server-side equivalent of $.ajax()

问题:

I want to perform an HTTP request from server-side code in a Google App Script with an Authorization header. Is there an App Script API for sending HTTP requests?

What's the equivalent of this code in a Google Apps Script?

 var api = "URL";
 $.ajax({
     type: 'GET',
     url: api,
     contentType: 'application/json',
     dataType:'json',
     data: {},
     beforeSend: function(xhr) {
         xhr.setRequestHeader('Authorization', makeBaseAuth('username', 'password'));
     }
});

You can send HTTP requests using the UrlFetchApp object. It has a fetch(url, params) method that returns a HTTPResponse with information about the result of the HTTP fetch.

function testapi(){

    var encode =  Utilities.base64Encode('username:password', Utilities.Charset.UTF_8);
    Logger.log(encode);

    var option = {
      headers : {
            Authorization: "Basic "+ encode
      }   
    }

    var url = "URL";
    var response = UrlFetchApp.fetch(url, option).getContentText()
    response = JSON.parse(response);

    for (var key in response){
      Logger.log(key);
    }
}
