Jira API 帮助 C# HttpClient

Question

Okay, so I'm very new to using API's in code and I've been able to use a few that were actually pretty easy. But none of them required authentication. I've been trying to use Jira's REST API service via C#'s HttpClient class. See code below:

public void UpdateJiraIssue(string issueValue)
        {
            string url = $@"http://jira.mySite.com/rest/api/2/issue/{issueValue}/editmeta";
            string jsonString = @"myNeatJsonData";
            var content = new StringContent(jsonString, Encoding.UTF8, "application/json");

            //Initialize Client
            HttpClient apiClient = new HttpClient();
            apiClient.BaseAddress = new System.Uri(url);
            apiClient.DefaultRequestHeaders.Accept.Clear();

            byte[] cred = UTF8Encoding.UTF8.GetBytes("username:password");
            apiClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(cred));
            apiClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

            async Task RunJiraAPI()
            {

                using (HttpResponseMessage resp = await apiClient.PostAsync("editmeta", content))
                {
                    if (resp.IsSuccessStatusCode)
                    {
                        var jsonSring = await resp.Content.ReadAsStringAsync();
                    }
                }
            }
            RunJiraAPI();

            return;
        }

The problem I run into is that I get a 401 error (Authentication). Here's what my 'resp' object contains when I run the code:

resp: {StatusCode: 401, ReasonPhrase: ' ', Version: 1.1, Content: System.Net.Http.StreamContent, Headers:
{
  X-AREQUESTID: 400x1314x1

}}

Request Message: {Method: POST, RequestUri: 'https://jira.rhlan.com/rest/api/2/issue/RHD-1116/editmeta', Version: 1.1, Content: System.Net.Http.StringContent, Headers:
{
  Authorization: Basic cWE6aGVjc29mdDEyMw==
  Accept: application/json
  Content-Type: Application/json; charset=utf-8
  Content-Length: 70
}}

Status Code: Unauthorized

I need to work on my json string a bit to get it working right (which is why I didn't include what it actually contains), but once I get passed the authentication error, I'll probably actually change things to do a get Jira issue via the API so I can see all the json data returned that way. Then I'll edit my json string accordingly.

Any ideas what I'm doing wrong here?

Answer 1

You can pass in credentials assuming you have a username and an api token.

string credentials= string.Format("{0}:{1}", username, apitoken);
    byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(credentials);

And in your apiClient you can use it like this.

apiClient.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteCredentials));

Answer 2

You need a username and api-token. Your api-token should be your login password.
