"将 json 对象属性映射到类"

Question

有一个这样的json字符串

{
   "result": 
   {
      "id":"1" 
   } 
}

Answer 1

你可以通过这种方式获得 id

  var id=  (await _httpClient.GetFromJsonAsync<User>("api/users/getme")).Result.Id;

Answer 2

您可以采用使用 System.Text.Json 反序列化匿名类型<\/a><\/em>的方法，并在HttpClient<\/code>中添加扩展方法以反序列化为匿名类型对象：

public static partial class HttpClientJsonExtensions
{
    public static Task<TValue?> GetAnonymousTypeFromJsonAsync<TValue>(this HttpClient client, string? requestUri, TValue anonymousTypeObject, CancellationToken cancellationToken = default)
        => client.GetFromJsonAsync<TValue>(requestUri, cancellationToken);
}
