如何在JIRA C＃中发送POST返回statusCode 400

Question

我尝试使用POST方法将数据发送到JIRA，但是在UploadString（）方法中收到错误400。

令牌正确，并且在POSTMAN中测试过的Json没问题，这是问题吗？

我已经待了好几天了，但我解决不了，有人可以帮我吗？谢谢

string json = @"{
                     'fields': {
                            'project': {

                                'id': '14538'
                            },
                            'issuetype': {

                            'customfield_10300': {

                                                    },
                                                    'name': 'ExmTick 40517',
                                                    'description': 'Register Peter Parker',
                                                    'helpText': '
                                                    'issueTypeId':'10835', 

                                                    'groupIds': [ '24' ]
                                                 }
                                            } 
                                }
                        }";

然后使用ATLASSIAN JIRA中的凭据编写的mi代码，请求为：

string jsonResponse = string.Empty;
    var userid = "user@example.com";
    var password = "QLodasdTCdt7Exampledsfsdf";
    var endpoint = "https://example.atlassian.net/rest/api/2/issue?";

    using (var client = new WebClient())
    {
        try
        {
            client.Encoding = 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)
        {
            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;
}

UTF8中的转换方法是：

private static string GetEncodedCredentials(string userid, string password)
    {
        string mergedCredentials = string.Format("{0}:{1}", userid, password);
        byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(mergedCredentials);
        return Convert.ToBase64String(byteCredentials);
    }
