在c#中使用承载令牌构建post HttpClient请求

Question

我不是c#专家，我在c#中有一个post httpRequest要开发，为此我创建了这个方法，它接受一个Uri，一个对象和一个承载令牌。

这个方法的目的是构建调用请求:

private HttpClient client = new HttpClient(); 
public async Task<UserResponse> CreateUser(Uri url, UserRequest userRequest, string token)
{

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
client.DefaultRequestHeaders.TryAddWithoutValidation("Content-Type", "application/json; charset=utf-8");

string requestObject = JsonConvert.SerializeObject(userRequest);
Console.WriteLine("My Object: " + requestObject);
var req = new HttpRequestMessage(HttpMethod.Post, url);
req.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);
req.Content = new StringContent(
requestObject,
Encoding.UTF8,
"application/json"
);
Console.WriteLine(req.ToString());
var response = await client.SendAsync(req); 

string output = await response.Content.ReadAsStringAsync();
Console.WriteLine(JsonConvert.DeserializeObject(output));
UserResponse returnValue = JsonConvert.DeserializeObject<UserResponse>(output);
return returnValue;
}

我的问题是，我不确定我传递正确的标题内容。返回的响应是一条错误消息，告诉我没有经过身份验证。

感谢

你必须这样添加标记:

var baseAddress = "http://....";
var api = ".....";
client.BaseAddress = new Uri(baseAddress);
var contentType = new MediaTypeWithQualityHeaderValue("application/json");
client.DefaultRequestHeaders.Accept.Add(contentType);
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);
var postData = JsonConvert.SerializeObject(userRequest);
contentData = new StringContent(postData, Encoding.UTF8, "application/json");
var response = await client.PostAsync(baseUrl + api, contentData);
if (response.IsSuccessStatusCode)
{
var stringData = await response.Content.ReadAsStringAsync();
return JsonConvert.DeserializeObject<UserResponse>(stringData);
}
else
{
}
