HttpClient 不返回 URI 的 json 值

Question

I am trying to use HttpClient to GET information from Jira, but I am unable to see any of the information. I want to be able to get all the bugs that match certain filters so that I can add them to a table in my program.

I have tried to access Jira with the rest api, but every time I do it says that the issue or project doesn't exist. The thing is that if I enter the URI into the bar at the top of my browser I can see the JSON text that I want. This leads me to believe that the reason my code is not returning these values is because of an authorization issue. I am using basic auth to send my credentials. I also want to add that I used cURL in cmd to test my credentials with basic auth and it worked.

public async Task<JiraModel> GetBugs()
        {
           using (var client = new HttpClient())
            {
                string url = "https://myurl.atlassian.net/rest/api/3/project/VCMF";

                String username = "username";
                String password = "apikey";
                String encoded = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("UTF-8").GetBytes(username + ":" + password));

                client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", "Basic " + encoded);
                client.BaseAddress = new Uri("https://myurl.atlassian.net/rest/api/3/project/VCMF");
                var response = await client.GetAsync(url);
                var content = await response.Content.ReadAsStringAsync();
                return JsonConvert.DeserializeObject<JiraModel>(content);
            }
        }

I should be getting the json results in string form by the end of this length of code, but I keep getting a 404 error instead that for this code specifically says "No project could be found with key 'VCMF'".

Answer 1

The issue here is that you're creating the authorization header incorrectly.

The constructor you're using for AuthenticationHeaderValue class takes two arguments: scheme and parameter:

public AuthenticationHeaderValue(string scheme, string parameter)
{
}

The first argument should be the scheme (Basic in this case) and the second, the base64-encoded credentials:

So instead of:

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Authorization", "Basic " + encoded);

It should be:

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", encoded);

Hope this helps!
