我正在尝试使用"Microsoft.AspNetCore.ResponseCaching"包在Web api中实现响应缓存.
I am trying to implement response caching in my web api using the "Microsoft.AspNetCore.ResponseCaching" package.
我正在使用Postman来测试应用程序并验证标头等.
I am using Postman to test the application and validate headers etc.
使用指定的最大年龄生成正确的标头,但邮递员似乎从api请求响应,而不使用缓存.响应时间完全没有变化,如果我调试控制器,我会看到它每次都被请求击中.
The correct headers are generated with the specified max-age but postman seems to request the response from the api and not using the cache. The response time does not vary at all and if I debug the controller I can see that it gets hit by the request every time.
启动类ConfigureServices(以及其他内容):
Startup class ConfigureServices (along with other stuff):
services.AddResponseCaching();启动类Configure(以及其他内容):
Startup class Configure (along with other stuff):
app.UseResponseCaching(); app.UseMvc();控制器操作:
[HttpGet("{employeeNr}", Name = EmployeeAction)] [ResponseCache(Duration = 50)] [Produces(typeof(EmployeeDto))] public async Task<IActionResult> GetEmployee(SpecificEmployeeParameters parameters) { if (!await _employeeRepository.EmployeeExists(parameters.EmployeeNr)) return NotFound(); if (!_typeHelperService.TypeHasProperties<EmployeeDto>(parameters.Fields)) return BadRequest(); var entity = await _employeeRepository.GetEmployee(parameters.EmployeeNr); var result = Mapper.Map<EmployeeDto>(entity); return Ok(result.ShapeData(parameters.Fields)); }邮递员的响应标头:
cache-control →private,max-age=50 content-type →application/json; charset=utf-8 date →Wed, 30 Aug 2017 11:53:06 GMT推荐答案
解决了该问题.上面的代码没问题! 邮递员通过设置来阻止缓存.
Fixed the issue. The code above is alright! Postman was preventing caching by a setting.
要解决此问题,请转到邮递员设置:
To fix this behaviour go to Postman Settings:
General -> Headers -> Send no-cache header -> Set to "OFF"更多推荐
