我正在尝试向Web应用程序的请求标头添加自定义标头。在我的Web应用程序中，我从Web api检索数据，在此请求中，我想添加一个包含字符串sessionID的自定义标头。我正在寻找一种通用的解决方案，这样我就不必在每次拨打电话之前都添加相同的代码。
我的控制器如下：
[HttpGet]
public async Task<ActionResult> getCall()
{
string url = "http://localhost:51080/";
string customerApi = "customer/1";
using (var client = new HttpClient())
{
//get logged in userID
HttpContext context = System.Web.HttpContext.Current;
string sessionID = context.Session["userID"].ToString();
//Create request and add headers
client.BaseAddress = new Uri(url);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//Custom header
//Response
HttpResponseMessage response = await client.GetAsync(customerApi);
if (response.IsSuccessStatusCode)
{
string jsondata = await response.Content.ReadAsStringAsync();
return Content(jsondata, "application/json");
}
return Json(1, JsonRequestBehavior.AllowGet);
}
}
希望任何人都能提供帮助！
谢谢！

DefaultRequestHeaders后面的集合具有Add方法，该方法可让您添加所需的标题：
client.DefaultRequestHeaders.Add("headerName", sesssionID);
