我正在尝试将一些数据输入数据库并在成功调用结束时获取 access_token。
当我调用传递此参数时:
一切顺利,用户注册并保存到数据库中,access_token 返回给用户:
但是,当我在 deviceId 值中添加符号 +、= 或\时,出现异常并且数据库中没有保存任何内容:

这是此调用的模型定义:
public class Registration
{
public string UserName { get; set; }
public string Password{ get; set; }
public string DeviceId { get; set; }
public string DeviceName { get; set; }
}
字段 deviceId 作为 UserName 保存到数据库中,根据它的定义,它是 NVARCHAR(1024)
NVARCHAR 是否可能不允许非字母和数字的字符?其他人有这样的问题吗?
编辑:这是问题所在的方法:
[Route("registration/request")]
public async Task<HttpResponseMessage> RegistrationRequest(Registration model)
{
try
{
MatrixLogManager.Info("Starting token creating.");
var request = HttpContext.Current.Request;
var tokenServiceUrl = request.Url.GetLeftPart(UriPartial.Authority) + request.ApplicationPath + "/Token";
MatrixLogManager.Info("Checking if model is valid.");
if (!ModelState.IsValid)
{
return Request.CreateResponse(BadRequest(ModelState));
}
using (MatrixServiceLayerLogin login = new MatrixServiceLayerLogin())
{
if (login.LoginUser(model.UserName, model.Password, true, true))
{
var personId = login.GetPersonId();
MatrixLogManager.Debug("User " + model.UserName + "successfully logged in on MatrixSTS.");
try
{
using (var authRepo = new AuthRepository())
{
ApplicationUser appUser = new UserFactory().CreateApplicationUser(model, personId);
IdentityResult result = await authRepo.RegisterUser(appUser);
EMailService.SendEmail(appUser);
IHttpActionResult errorResult = GetErrorResult(result);
if (errorResult != null)
{
return Request.CreateResponse(errorResult);
}
using (var client = new HttpClient())
{
var requestParams = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("grant_type", "password"),
new KeyValuePair<string, string>("username", appUser.UserName),
new KeyValuePair<string, string>("password", "0000")
};
var requestParamsFormUrlEncoded = new FormUrlEncodedContent(requestParams);
var tokenServiceResponse = await client.PostAsync(tokenServiceUrl, requestParamsFormUrlEncoded);
var responseString = await tokenServiceResponse.Content.ReadAsStringAsync();
var responseCode = tokenServiceResponse.StatusCode;
var responseMsg = new HttpResponseMessage(responseCode)
{
Content = new StringContent(responseString, Encoding.UTF8, "application/json")
};
responseMsg.Headers.Add("PSK", appUser.PSK);
return responseMsg;
}
}
}
catch (Exception ex)
{
MatrixLogManager.Error("Error: ", ex);
throw ex;
}
}
else
{
return Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "Invalid username or password.");
}
}
}
catch (Exception ex)
{
MatrixLogManager.Error(string.Format("Error while trying registring user: Exception = {0} InnerException {1}", ex.Message, ex.InnerException.Message));
throw;
}
}
Try-Catch 没有捕获任何异常,真正的异常发生在这里:
public async Task<IdentityResult> RegisterUser(ApplicationUser userModel)
{
userModel.TwoFactorEnabled = true;
userModel.PSK = TimeSensitivePassCode.GeneratePresharedKey();
var result = await _userManager.CreateAsync(userModel, "0000");
return result;
}
当结果所在的行返回给客户端时。我猜想之前排队存钱不太顺利。我将在该部分代码中设置 try-catch 并发布异常。
最佳答案
这通常发生在您将 Response 包装两次时。
考虑您的方法返回 Task<IHttpActionResult>
而不是 Task<HttpResponseMessage>
并注意你是如何包装 errorResult
的调用时两次:
return Request.CreateResponse(errorResult);
这可能会让您相信是您的 token 服务中的错误导致了这个问题,而实际上双重包装是:)
考虑以下几点:
[Route("registration/request")]
public async Task<IHttpResult> RegistrationRequest(Registration model)
{
try
{
MatrixLogManager.Info("Starting token creating.");
var request = HttpContext.Current.Request;
var tokenServiceUrl = request.Url.GetLeftPart(UriPartial.Authority) + request.ApplicationPath + "/Token";
MatrixLogManager.Info("Checking if model is valid.");
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
using (MatrixServiceLayerLogin login = new MatrixServiceLayerLogin())
{
if (login.LoginUser(model.UserName, model.Password, true, true))
{
var personId = login.GetPersonId();
MatrixLogManager.Debug("User " + model.UserName + "successfully logged in on MatrixSTS.");
try
{
using (var authRepo = new AuthRepository())
{
ApplicationUser appUser = new UserFactory().CreateApplicationUser(model, personId);
IdentityResult result = await authRepo.RegisterUser(appUser);
EMailService.SendEmail(appUser);
IHttpActionResult errorResult = GetErrorResult(result);
if (errorResult != null)
{
// MAJOR CHANGE here
return errorResult;
}
using (var client = new HttpClient())
{
var requestParams = new List<KeyValuePair<string, string>>
{
new KeyValuePair<string, string>("grant_type", "password"),
new KeyValuePair<string, string>("username", appUser.UserName),
new KeyValuePair<string, string>("password", "0000")
};
var requestParamsFormUrlEncoded = new FormUrlEncodedContent(requestParams);
var tokenServiceResponse = await client.PostAsync(tokenServiceUrl, requestParamsFormUrlEncoded);
var responseString = await tokenServiceResponse.Content.ReadAsStringAsync();
var responseCode = tokenServiceResponse.StatusCode;
var responseMsg = new HttpResponseMessage(responseCode)
{
Content = new StringContent(responseString, Encoding.UTF8, "application/json")
};
responseMsg.Headers.Add("PSK", appUser.PSK);
return responseMsg;
}
}
}
catch (Exception ex)
{
MatrixLogManager.Error("Error: ", ex);
throw ex;
}
}
else
{
return Request.CreateErrorResponse(HttpStatusCode.Unauthorized, "Invalid username or password.");
}
}
}
catch (Exception ex)
{
MatrixLogManager.Error(string.Format("Error while trying registring user: Exception = {0} InnerException {1}", ex.Message, ex.InnerException.Message));
throw;
}
}
