为Spring TestRestTemplate集成测试添加标头值

Question

I am using TestRestTemplate for integration testing on our product.

I have one test that looks like this:

@Test
public void testDeviceQuery() {
    ResponseEntity<Page> deviceInfoPage = template.getForEntity(base, Page.class);

    // validation code here
}

This particular request expects a Header value. Can someone please let me know how I can add a header to the TestRestTemplate call?

Answer 1

Update : As of Spring Boot 1.4.0 , TestRestTemplate does not extend RestTemplate anymore but still provides the same API as RestTemplate .

TestRestTemplate extends RestTemplate provides the same API as the RestTemplate , so you can use that same API for sending requests. For example:

HttpHeaders headers = new HttpHeaders();
headers.add("your_header", "its_value");
template.exchange(base, HttpMethod.GET, new HttpEntity<>(headers), Page.class);

Answer 2

If you want all of your requests using TestRestTemplate to include certain headers, you could add the following to your setup:

testRestTemplate.getRestTemplate().setInterceptors(
        Collections.singletonList((request, body, execution) -> {
            request.getHeaders()
                    .add("header-name", "value");
            return execution.execute(request, body);
        }));

Answer 3

If you want to use multiple headers for all your requests, you can add the below

 import org.apache.http.Header;
 import org.apache.http.impl.client.CloseableHttpClient;
 import org.apache.http.impl.client.HttpClients;
 import org.apache.http.message.BasicHeader;
 import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;


 private void setTestRestTemplateHeaders() {
    Header header = new BasicHeader("header", "value");
    Header header2 = new BasicHeader("header2", "value2");
    List<Header> headers = new ArrayList<Header>();
    headers.add(header);
    headers.add(header2);
    CloseableHttpClient httpClient = HttpClients.custom().setDefaultHeaders(headers).build();
    testRestTemplate.getRestTemplate().setRequestFactory(new HttpComponentsClientHttpRequestFactory(httpClient));
 }

Once the headers are set you can either use TestRestTemplate [testRestTemplate] or RestTemplate [testRestTemplate.getRestTemplate()] for your REST calls
