Changing REST Headers When Web Service Testing

When you are writing REST web service tests, you can use the following code to set the HTTP headers:

      var headers = SeS('RestHeaderTest1_Get_Session').GetRequestHeaders();
      SeS('RestHeaderTest1_Get_Session').SetRequestHeaders([{'Name': 'Content-Type', 'Value': 'application/json'}]);
      headers = SeS('RestHeaderTest1_Get_Session').GetRequestHeaders();
      Tester.Message(headers[0].Value);

If you would like to change thee headers (e.g. in this case to switch the Content-Type from JSON to XML, you might try the following:

      //Set headers to XML - does not work
      SeS('RestHeaderTest1_Get_Session').SetRequestHeaders([{'Name': 'Content-Type', 'Value': 'application/xml'}]);
      headers = SeS('RestHeaderTest1_Get_Session').GetRequestHeaders();
      Tester.Message(headers[0].Value);

However that does not work, you instead should use the following:

      //Set headers to XML - does work
      headers[0].Value = 'application/xml';
      headers = SeS('RestHeaderTest1_Get_Session').GetRequestHeaders();
      Tester.Message(headers[0].Value);   

Another option that we recommend is using the new global Session object that was introduced in Rapise 5.0:

//Set original header
Session.SetRequestHeaders(...)
SeS('RestHeaderTest1_Get_Session').DoSomething(...)

//Set new headers
Session.SetRequestHeaders(...)
SeS('RestHeaderTest1_Get_Session').DoSomethingWithNewHeaders(...)
