TraceRequest

Overview

The TraceRequest object enables executing HTTP TRACE requests with advanced configuration options. It allows adding custom headers, managing authentication credentials, and handling both synchronous and asynchronous request executions.

For asynchronous requests, success and error callbacks can be defined to process responses or handle errors effectively.

Notable methods include addHeader, which adds custom headers to the request, and executeRequest, which performs the TRACE request synchronously. The object also supports asynchronous execution through executeAsyncRequest, providing flexibility for non-blocking operations. The usePreemptiveAuthentication method can enable credentials to be sent in the initial request, optimizing performance for specific scenarios.

For broader context on HTTP operations, refer to the Http plugin documentation.

Methods Detailed

addHeader(headerName, value)

Add a header to the request.

Parameters

• String headerName ;
• String value ;

Returns: Boolean A boolean indicating whether the header was successfully added to the request.

Sample

method.addHeader('Content-type','text/xml; charset=ISO-8859-1')

executeAsyncRequest()

Execute the request method asynchronous a Promise is returned which will be resolved or rejected when the request is completed or failed.

This Response can be a response with a different status code then just 200, it could also be 500, which is still a valid response from the server. So you need to test the Reponse.getStatusCode() for that to know if everything did go OK. If no response is received (request errors out), the Promise is rejected with exception message as the value.

You can use Promise.all([promise1, promise2, promise3]) to wait for multiple promises to complete. A shortcut for this would be to use httpClient.executeRequest(requestArray) that returns 1 promise that is called when all of them are done.

Returns: Promise

Sample

request.executeAsyncRequest().then(response => { // handle the response }).catch(errorMessage => { // handle the error });})

executeAsyncRequest(username, password)

Execute the request method asynchronous a Promise is returned which will be resolved or rejected when the request is completed or failed.

Parameters

• String username the user name
• String password the password

Returns: Promise

Sample

request.executeAsyncRequest().then(response => { // handle the response }).catch(errorMessage => { // handle the error });})

executeAsyncRequest(username, password, workstation, domain)

Parameters

• String username the user name
• String password the password
• String workstation The workstation the authentication request is originating from.
• String domain The domain to authenticate within.

Returns: Promise

Sample

request.executeAsyncRequest().then(response => { // handle the response }).catch(errorMessage => { // handle the error });})

executeAsyncRequest(username, password, workstation, domain, successCallbackMethod, errorCallbackMethod)

Execute the request method asynchronous. Success callback method will be called when response is received. Response is sent as parameter in callback. This Response can be a response with a different status code then just 200, it could also be 500, which is still a valid response from the server, this won't go into the error callback. So you need to test the Reponse.getStatusCode() for that to know if everything did go OK. If no response is received (request errors out), the errorCallbackMethod is called with exception message as parameter.

Parameters

• String username the user name
• String password the password
• String workstation The workstation the authentication request is originating from.
• String domain The domain to authenticate within.
• Function successCallbackMethod callbackMethod to be called after response is received
• Function errorCallbackMethod callbackMethod to be called if request errors out

Returns: void

Sample

method.executeAsyncRequest('username','password','mycomputername','domain',globals.successCallback,globals.errorCallback)

executeAsyncRequest(username, password, workstation, domain, successCallbackMethod, errorCallbackMethod, callbackExtraArgs)

Execute the request method asynchronous using windows authentication. Success callback method will be called when response is received. Response is sent as parameter in callback followed by any 'callbackExtraArgs' that were given. This Response can be a response with a different status code then just 200, it could also be 500, which is still a valid response from the server, this won't go into the error callback. So you need to test the Reponse.getStatusCode() for that to know if everything did go OK. If no response is received (request errors out, network errors), the errorCallbackMethod is called with exception message as parameter followed by any 'callbackExtraArgs' that were given.

Parameters

• String username the user name
• String password the password
• String workstation The workstation the authentication request is originating from.
• String domain The domain to authenticate within.
• Function successCallbackMethod callbackMethod to be called after response is received
• Function errorCallbackMethod callbackMethod to be called if request errors out
• Array callbackExtraArgs extra arguments that will be passed to the callback methods; can be used to identify from which request the response arrived when using the same callback method for multiple requests. Please use only simple JSON arguments (primitive types or array/objects of primitive types)

Returns: void

Sample

method.executeAsyncRequest('username','password','mycomputername','domain',globals.successCallback,globals.errorCallback, [callIDInt])
