如何使用 Web API 通过 Web 方法管理安全性?



我的场景如下:

我已经为移动应用程序创建了WEB API。

  • 令牌调用 - 它返回授权令牌成功和barer令牌 详
  • GetCompanyDetails(int loginId)
  • GetCompanyCustomer(int companyId)

我在数据库中有如下表:

登录表:

ID| Username | Password | UserType | CreatedDate
1 | Alex | P#ssword | Company  | 2017-05-04
2 | Jhon | 4548@sd  | Company  | 2017-05-10
3 | Rubby | R#$S3343| Customer | 2017-05-11
4 | Moris | M#$353  | Customer | 2017-05-11
5 | Febio | Feb@153  | Customer | 2017-05-11 

公司明细表:

ID | LoginID | CompanyName | Address | CreatedDate | Location
5  |  1      | ALEX Company| Street 1| 2017-05-04  | USA
7  |  2      | JHON INC    | NJ, OPP PR market| 2017-05-10 | USA

客户明细表:

ID | LoginID | Address   | CreatedDate | Location
10  |  3      | Address 1| 2017-05-11  | USA
12  |  4      | Address 2| 2017-05-11 | USA
13  |  5      | Address 3| 2017-05-11 | USA

公司客户表:

ID | CompanyID | CustomerID
1  |  5        | 10
1  |  5        | 12
2  |  7        | 13

一旦我授权了API,那么在我调用该方法以获取公司客户之后。 那次我正在传递公司 ID 以获得客户。.

[HttpGet]
[Authorize(Roles=("Company")]
public List<Customer> CompanyCustomer(int companyId)
{
//Return the list of customer by companyId
}

我的观点是如何验证令牌授权时是同一用户的用户。
假设我要求

  • ALEX 公司的公司 ID = 5,那么我称公司客户(5) 它 将返回所有客户
  • 之后应该调用公司客户(7),然后它仍然返回另一家公司的所有客户。

    如何通过请求的用户检测该 API 调用方令牌?

如何处理这种安全性?

public sealed class PrivateAttribute : Attribute, IAuthorizationFilter {
public Task<HttpResponseMessage> ExecuteAuthorizationFilterAsync(
HttpActionContext actionContext,
CancellationToken cancellationToken,
Func<Task<HttpResponseMessage>> continuation) {
var claimsPrincipal = actionContext.RequestContext.Principal as ClaimsPrincipal;
if (actionContext.RequestContext.RouteData.Values.ContainsKey(CONSTANTS.USER_ID_KEY) && claimsPrincipal != null) {
var requestedID = actionContext.RequestContext.RouteData.Values[CONSTANTS.USER_ID_KEY];
if (claimsPrincipal.HasClaim(CONSTANTS.USER_ID_KEY, requestedID.ToString())) {
return continuation();
} else { // someone is trying to get resources of another user
return whatever fail;
}
} else { // there is no {id} paramter in the route, nothing to do
return continuation();
}
}
public bool AllowMultiple => false;
}

在身份验证时:

public override async Task GrantResourceOwnerCredentials(
OAuthGrantResourceOwnerCredentialsContext context) {
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
using (var authRepo = AuthRepository.Create()) {
var findUserResult = await authRepo.FindUser(context.UserName, context.Password);
if (findUserResult == UserModel.NoUser) {
context.SetError("error", "User not found.");
} else {
var identity = new ClaimsIdentity(context.Options.AuthenticationType);
identity.AddClaim( // this is important, [PrivateAttribute] relies on this
new Claim(CONSTANTS.USER_ID_KEY, findUserResult.ID.ToString()));
context.Validated(identity);
}
}
}
