有什么办法可以避免此代码中的return null
?
@Test
public void testFrontEndPing() throws Exception {
String url = frontEndUrl("ping");
HttpGet httpGet = new HttpGet(url);
httpClient.execute(httpGet, httpResponse -> {
assertEquals(200, httpResponse.getStatusLine().getStatusCode());
return null;
}
);
}
最佳答案
您可以编写一个包装方法,如下所示:
static void execute(HttpClient client, HttpUriRequest request,
Consumer<HttpResponse> handler) {
client.<Void>execute(request, response -> {
handler.accept(response);
return null;
});
}
并像这样使用它:
execute(httpClient, httpGet, httpResponse ->
assertEquals(200, httpResponse.getStatusLine().getStatusCode()));
