Custom test of http header with spring-test-mvc
提问by Avi
I'm testing my MVC service with spring-test-mvcI used something like:
我正在使用以下内容测试我的 MVC 服务spring-test-mvc：
MockMvc mockMvc = standaloneSetup(controller).build();
mockMvc.perform(get("<my-url>")).andExpect(content().bytes(expectedBytes)).andExpect(content().type("image/png"))
.andExpect(header().string("cache-control", "max-age=3600"));
Which worked fine.
哪个工作得很好。
Now I changed the cache image to be random in a specific range. For example, instead of 3600it could be 3500-3700. I'm trying to figure out how I can get the header value and do some tests on it instead of using this pattern of andExpect.
现在我将缓存图像更改为特定范围内的随机图像。例如，代替3600它可能是3500-3700. 我试图弄清楚如何获取标头值并对其进行一些测试，而不是使用andExpect.

Perhaps you mean something like this.
也许你的意思是这样的。
MvcResult mvcResult = mvc.perform(get("/")).andReturn();
String headerValue = mvcResult.getResponse().getHeader("headerName");

To add a little more detail to Admit's answer: if you also have access to a JAX-RS implementation in your code, you can use the CacheControl object to make a very explicit test (example using hamcrest matchers):
为 Admit 的回答添加更多细节：如果您还可以访问代码中的 JAX-RS 实现，则可以使用 CacheControl 对象进行非常明确的测试（例如使用 hamcrest 匹配器）：
int maxAge = CacheControl
.valueOf(mvcResult.getResponse().getHeader("Cache-Control"))
.getMaxAge();
assertThat(maxAge, is(both(greaterThanOrEqualTo(3500)).and(lessThanOrEqualTo(3700))));
