如何为所有WebApi响应禁用缓存,以避免IE使用(从缓存)响应 [英] How to disable caching for all WebApi responses in order to avoid IE using (from cache) responses
问题描述
我有一个简单的ASP.NET Core 2.2 Web Api控制器:
I have a simple ASP.NET Core 2.2 Web Api controller:
[ApiVersion("1.0")]
[Route("api/[controller]")]
[ApiController]
public class TestScenariosController : Controller
{
[HttpGet("v2")]
public ActionResult<List<TestScenarioItem>> GetAll()
{
var entities = _dbContext.TestScenarios.AsNoTracking().Select(e => new TestScenarioItem
{
Id = e.Id,
Name = e.Name,
Description = e.Description,
}).ToList();
return entities;
}
}
当我使用 @ angular/common/http
从angular应用查询此操作时:
When I query this action from angular app using @angular/common/http
:
this.http.get<TestScenarioItem[]>(`${this.baseUrl}/api/TestScenarios/v2`);
在IE11中,我只得到缓存的结果.
In IE11, I only get the cached result.
如何为所有Web API响应禁用缓存?
推荐答案
You can add ResponseCacheAttribute
to the controller, like this:
[ApiVersion("1.0")]
[Route("api/[controller]")]
[ApiController]
[ResponseCache(NoStore = true, Location = ResponseCacheLocation.None)]
public class TestScenariosController : Controller
{
...
}
或者,您可以添加 ResponseCacheAttribute
作为全局过滤器,如下所示:
Alternatively, you can add ResponseCacheAttribute
as a global filter, like this:
services
.AddMvc(o =>
{
o.Filters.Add(new ResponseCacheAttribute { NoStore = true, Location = ResponseCacheLocation.None });
});
这将禁用MVC请求的所有缓存,并且可以通过将 ResponseCacheAttribute
再次应用于所需的控制器/操作来针对每个控制器/操作来覆盖.
This disables all caching for MVC requests and can be overridden per controller/action by applying ResponseCacheAttribute
again to the desired controller/action.
请参见文档中的ResponseCache属性以获取更多信息.
See ResponseCache attribute in the docs for more information.
