【中文标题】profile.User.Identity.IsAuthenticated 返回 false 没有人帮助我【英文标题】：profile.User.Identity.IsAuthenticated return false nobody helped me 【发布时间】：2021-09-02 23:40:47 【问题描述】：我正在尝试将带有另一个项目 (c#) 的 Web 服务构建连接到我的项目 (asp.net mvc)。目前我可以登录和注销，但我无法将查询带到我的项目中，因为 profile.User.Identity.IsAuthenticated 它返回 false。
这是我如何调用登录查询和另一个查询来带来一些信息。当我使用网络浏览器连接时，它们都可以工作。问题在于身份。
我的项目
//LOGIN USING WEBSERVICE
[HttpPost]
public IActionResult Login(LoginViewModel _login)
using (var client = new WebClient())
client.Headers.Add("Content-Type:application/json"); //Content-Type
client.Headers.Add("Accept:application/json");
string result =
client.DownloadString("http://localhost/Services/BlueLifeDataService.svc/Login?login='" +
_login.db + "\\" + _login.Username + "'&password='" + _login.Password + "'");
var _result = JsonConvert.DeserializeObject<dynamic>(result);
if(_result["d"]["Login"].Value == true)
Response.Cookies.Append("User", _login.Username);
return RedirectToAction("Index");
else
return View();
//BRING QUERY
public IActionResult Get()
using (var client = new WebClient())
client.Headers.Add("Content-Type:application/json"); //Content-Type
client.Headers.Add("Accept:application/json");
string result =
client.DownloadString("http://localhost/Services/BlueLifeDataService.svc/Aircraft?");
var _result = JsonConvert.DeserializeObject<dynamic>(result);
return View();

【问题讨论】：
【参考方案1】：从我在您的项目代码中看到的内容来看，您正在 Get 操作中创建一个新的 WebClient，但您没有传递您在调用 Web 服务时在 Login 操作中收到的 FormsAuthentication cookie -因此它无法验证该请求。你可能想看看：WebClient accessing page with credentials
