C# 如何使用System.Net.Http发送下面所示的cURL请求？

我试图使用Zendesk的票证提交API，在他们的文档中，他们给出了以下cURL示例：

curl https://{subdomain}.zendesk.com/api/v2/tickets.json\
-d'{“票证”：{“请求者”：{“姓名”：“客户”，“电子邮件”：thecustomer@domain.com“}，”主题“：“我的打印机着火了！”，“评论“：{”正文“：“烟很鲜艳。”}”\
-H“内容类型：application/json”-v-u{email_address}:{password}-X POST

我正在尝试使用System.Net.Http库发出此POST请求：

var httpClient = new HttpClient();
HttpContent httpContent = new StringContent(JsonConvert.SerializeObject(model));
if (httpContent.Headers.Any(r => r.Key == "Content-Type"))
    httpContent.Headers.Remove("Content-Type");
httpContent.Headers.Add("Content-Type", "application/json");
httpContent.Headers.Add("Authorization", String.Format("Basic {0}", Convert.ToBase64String(Encoding.ASCII.GetBytes("{user}:{password}"))));
var httpResult = httpClient.PostAsync(WebConfigAppSettings.ZendeskTicket, httpContent);

当我尝试将授权标头添加到内容时，我不断收到一个错误。我现在明白了HttpContent只应该包含内容类型头

如何创建和发送POST请求，以便使用System.Net.Http库设置内容类型标头、授权标头，并在正文中包含Json？

我使用以下代码构建请求：

HttpContent httpContent = new StringContent(JsonConvert.SerializeObject(new { ticket = model }));
if (httpContent.Headers.Any(r => r.Key == "Content-Type"))
    httpContent.Headers.Remove("Content-Type");
httpContent.Headers.Add("Content-Type", "application/json");
var httpRequest = new HttpRequestMessage()
{
    RequestUri = new Uri(WebConfigAppSettings.ZendeskTicket),
    Method = HttpMethod.Post,
    Content = httpContent
};
httpRequest.Headers.Add("Authorization", String.Format("Basic {0}", Convert.ToBase64String(Encoding.UTF8.GetBytes(@"{username}:{password}"))));
httpResult = httpClient.SendAsync(httpRequest);

基本上，我分别构建内容，添加主体和设置标题。然后，我将身份验证头添加到

httpRequest

对象中。因此，我必须将内容头添加到

httpContent

对象，并将授权头添加到

httpRequest

对象
