Use Header Manager to pass the Token as a Header so you would have:

Answer 2

A bit easier JMeter setup (login/get):

Thread Group

• HTTP Request, Body Data: { "Login":"some", "Password":"credentials" }

  • HTTP Header Manager: content-type application/json
  • JSON Extractor - Names of created variables: Token; JSON Path expression: tokenName (root level in my case)

• HTTP Request

  • HTTP Header Manager: content-type -> application/json; Authorization -> Bearer ${Token}
  • Response Assertion: Fields to Test = Response Code; Pattern Matching Rules = Equals, Not; Pattern to Test 401

• View Results Tree to check results

Local IE Ajax version in case...

<SCRIPT>
var baseUri = 'https://localhost:port';
var tokenUri = '/something';
var getUri = '/restrictedData';
var token;
var form = { "Login":"some", "Password":"credentials" };
postRequest(baseUri + tokenUri, form, gotToken)

function gotToken(progress) {
    var response = progress.srcElement;
    if (response.status != 200) {
        document.body.innerText = "Error:\n" + response.response;
        return;
    }
    token = JSON.parse(response.response);
    console.log(JSON.stringify(token));
    var restricted = getRequest(baseUri + getUri, token.tokenName, gotRestricted);
}
function gotRestricted(progress) {
    var jsonStr = progress.srcElement.response;
    var jsonObj = JSON.parse(jsonStr);
    document.body.innerText = JSON.stringify(token,null,2) + '\n\n' + JSON.stringify(jsonObj,null,2);
}
function getRequest(url, token, callback) {
    var xhr = new XMLHttpRequest();
    xhr.onloadend = callback;
    xhr.open('GET', url);
    xhr.setRequestHeader('contentType', 'application/json')
    if (token) xhr.setRequestHeader("Authorization", "Bearer " + token);
    xhr.send();
    return xhr;
}
function postRequest(url, body, callback) {
    var xhr = new XMLHttpRequest();
    xhr.onloadend = callback;
    xhr.open('POST', url);
    xhr.setRequestHeader('Content-Type', 'application/json')
    xhr.send(JSON.stringify(body));
    return xhr;
}
</SCRIPT>

Answer 3

Add Bearer ${token} in HTTP Header Manager available under failing HTTP Request.

Answer 4

use Authorization as parameter name and value should be Bearer ${variable_name}
