创建问题Jira REST API（400错误请求）

Question

问题

我正在尝试使用HttpWebRequest创建对我们内部Jira服务器的REST API调用。但是不知何故，我不断收到（400）错误的请求错误。我也尝试过使用WebClient和其他方法，但是似乎找不到正确的方法。有什么建议吗？

URL 是正确的

用户是正确的

密码是正确的

JSON数据也正确

必须有另一种访问远程服务器的方式吗？我一直在搜索，但似乎找不到解决方法。

我的代码

public static void CreateJiraRequest(JiraApiObject.RootObject jiraApiObject)
{
    string url = "https://jira-test.ch.*********.net/rest/api/latest/issue/";
    string user = "peno.ch";
    string password = "**********";

    var request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";
    request.ContentType = "application/json";
    request.Credentials = new System.Net.NetworkCredential(user, password);

    string data = JsonConvert.SerializeObject(jiraApiObject);

    using (var webStream = request.GetRequestStream())
    using (var requestWriter = new StreamWriter(webStream, System.Text.Encoding.ASCII))
    {
        requestWriter.Write(data);
    }

    try
    {
        var webResponse = request.GetResponse();
        using (var responseReader = new StreamReader(webResponse.GetResponseStream()))
        {
            string response = responseReader.ReadToEnd();
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

JSON

{
    "fields": {
       "project":
       {
          "key": "FOO"
       },
       "summary": "Test the REST API",
       "issuetype": {
          "name": "Task"
       }
   }
}

异常

在request.GetResponse();上输入try块时会发生异常

其他信息：远程服务器返回错误：（400）错误的请求。

解决方案

上面的代码中的问题是Jira需要编码的凭据。如果不对凭据进行编码，那么Jira服务器将返回400 Bad Request错误，并且没有特定信息。

我编写了两个新功能，一个用于API请求，另一个用于凭据的编码。

API调用

[TestClass]
public class FruitTests
{
    [TestMethod]
    public void WhichConstructorIsUsed()
    {
        var fruits = new List<IFruit>();
        fruits.Add(new Apple(Colors.Red, 5));
        fruits.Add(new Banana(Colors.Yellow, 20));

        var clonedFruits = fruits.Select(f => new Apple(f));

        Console.WriteLine(string.Join("\n", clonedFruits));
    }
}

编码功能

public static string PostJsonRequest(string endpoint, string userid, string password, string json)
    {
        // Create string to hold JSON response
        string jsonResponse = string.Empty;

        using (var client = new WebClient())
        {
            try
            {
                client.Encoding = System.Text.Encoding.UTF8;
                client.Headers.Set("Authorization", "Basic " + GetEncodedCredentials(userid, password));
                client.Headers.Add("Content-Type: application/json");
                client.Headers.Add("Accept", "application/json");
                var uri = new Uri(endpoint);
                var response = client.UploadString(uri, "POST", json);
                jsonResponse = response;
            }
            catch (WebException ex)
            {
                // Http Error
                if (ex.Status == WebExceptionStatus.ProtocolError)
                {
                    HttpWebResponse wrsp = (HttpWebResponse)ex.Response;
                    var statusCode = (int)wrsp.StatusCode;
                    var msg = wrsp.StatusDescription;
                    throw new HttpException(statusCode, msg);
                }
                else
                {
                    throw new HttpException(500, ex.Message);
                }
            }
        }

        return jsonResponse;
    }
