是否不返回HttpClient - body内容？

HttpClient httpClient = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "https://example.com");
request.Headers.Add("Accept", "text/html");
HttpResponseMessage response = await httpClient.SendAsync(request);

HttpStatusCode statusCode = response.StatusCode;
HttpHeaders headers = response.Headers;

HttpClient httpClient = new HttpClient();
HttpResponseMessage response = await httpClient.GetAsync("https://example.com/largefile.txt");
using (Stream contentStream = await response.Content.ReadAsStreamAsync())
{
    // 在此处处理响应流，如将其保存到本地文件
}

HttpClient httpClient = new HttpClient();
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, "https://example.com");
// 设置请求的内容、头部等
Task<HttpResponseMessage> responseTask = httpClient.SendAsync(request);

// 继续执行其他操作，无需等待响应返回
