我的代码：
OkHttpClient client = new OkHttpClient();
HttpUrl httpUrl = HttpUrl.parse(url).newBuilder().addQueryParameter("t", Base64.encodeBase64String(value.getBytes())).build();
Request request = new Request.Builder().url(httpUrl).get().build();
try (Response response = client.newCall(request).execute()) {
System.out.println(response.body().string());
} catch (Exception e) {
System.out.println(e.toString());
}
在Java 8 + apache-tomcat-9.0.14 + okhttp 3.13.1上使用此代码

我尝试在上下文关闭中使用强制关闭（来自官方javadoc），但仍收到警告。
