我正在尝试从 Java 9 测试新的 HttpClient。出于测试目的，我正在使用https://jsonplaceholder.typicode.com提供的 api 。但是，我收到握手异常并且不知道原因。
我正在运行的代码：
private final String TEST_URI = "https://jsonplaceholder.typicode.com/posts";
@Test
public void shouldReturnStatusOKWhenSendGetRequest() throws IOException, InterruptedException, URISyntaxException {
HttpRequest request = HttpRequest.newBuilder()
.uri(new URI(TEST_URI))
.GET()
.build();
HttpResponse<String> response = HttpClient.newHttpClient()
.send(request, HttpResponse.BodyHandler.asString());
assertThat(response.statusCode(), equalTo(HttpURLConnection.HTTP_OK));
}
我收到一个例外：
