我為我的桌面軟件創建了一個 API，以避免每次我想對 HttpClient 標頭進行更改時進行編碼和重建，但我不知道如何創建自定義 HttpRequestHeader 列表并將其作為請求標頭添加到 HttpClient 中。我正在尋找這樣的解決方案：clients.DefaultRequestHeaders = list_of_json_header_values;到目前為止，這是我發出請求的代碼：public static string DownloadSource(string link){    try    {        HttpClientHandler hch = new HttpClientHandler();        hch.Proxy = null;        hch.UseProxy = false;        using (HttpClient clients = new HttpClient(hch))        {            //clients.DefaultRequestHeaders = list_of_json_header_values; ???            using (HttpResponseMessage response = clients.GetAsync(link).Result)            {                using (HttpContent content = response.Content)                {                    return content.ReadAsStringAsync().Result;                }            }        }    }    catch (Exception _ex)    {        MessageBox.Show(_ex.ToString());    }}這是我從 JSON 獲取標頭的方法：var headers_json = "json here";var objects = JObject.Parse(headers_json);foreach (var item in objects["header_settings"]){    //list_of_json_header_values.Add(item.ToString()); ???    Console.WriteLine(item.ToString());}控制臺輸出："Cache-Control": "no-cache""User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:64.0) Gecko/20100101 Firefox/64.0""Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8""Accept-Language": "en-GB,en;q=0.5"
