Error: Unrecognized field "username" on jql request

[William Ross]

Hi,

I create an application in which I can see how many hours users have logged in. For this I have to carry out the next following jql request via the REST API.

worklogDate >= "2018/03/26" && worklogDate <= "2018/03/30" ORDER BY key ASC

I wrote this code

require 'config.php';  
    $ch = curl_init( atlassinaURL.'/rest/api/2/search/?jql=worklogDate%20%3E%3D%20%222018%2F03%2F26%22%20%26%26%20worklogDate%20%3C%3D%20%222018%2F03%2F30%22%20ORDER%20BY%20key%20ASC');
    $jsonData = array( 
       'username' => JiraUser,
        'password' => JiraPass );
    $jsonDataEncoded = json_encode($jsonData);

    curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
    $result = curl_exec($ch);

    curl_close($ch);
    $sess_arr = json_decode($result, true);
    
    if(isset($sess_arr['errorMessages'][0])) {
        echo $sess_arr['errorMessages'][0];
    }else {
        var_dump($sess_arr);
    }

When I call this page, I get the following message back

Unrecognized field "username" (Class com.atlassian.jira.rest.v2.search.SearchRequestBean), not marked as ignorable
 at [Source: org.apache.catalina.connector.CoyoteInputStream@3f8b53db; line: 1, column: 14] (through reference chain: com.atlassian.jira.rest.v2.search.SearchRequestBean["username"])

I searched the internet, but I did not find the solution. Can you help me?

Your post is sending the user name and password as though they are on-screen fields.

They are not fields, they are data for authentication.  Please have a read of https://developer.atlassian.com/server/jira/platform/rest-apis/ concentrating on the authentication sections
