Question

我正在尝试使用Vert.x Web客户端3.5.0（和Java 8）通过HTTPS发送GET请求。

Vertx vertx = Vertx.vertx();
WebClientOptions clientOptions = new WebClientOptions();
WebClient webClient = WebClient.create(vertx, clientOptions);
Handler<AsyncResult<HttpResponse<Buffer>>> testHandler = asyncResult -> {
    System.out.println("async = " + asyncResult);
    System.out.println("async result = " + asyncResult.result());
    System.out.println("async failed = " + asyncResult.failed());
    System.out.println("async succeeded = " + asyncResult.succeeded());
    System.out.println("async cause = " + asyncResult.cause());
};
webClient.get(443, "oauth.vk.com", "/access_token").
    addQueryParam("client_id", appId).
    addQueryParam("client_secret", secureKey).
    addQueryParam("v", apiVersion)
    addQueryParam("grant_type", "client_credentials").
    ssl(true).
    send(testHandler);

它适用于我的本地计算机（Windows 10），但在Ubuntu（17.04 x64）服务器上失败。 asyncResult.failed()是true。但asyncResult.cause()为null。

我使用cURL进行了测试，效果很好;看起来像Vert.x和OpenSSL交互的问题。

这是我Maven的POM文件的摘录：

<dependency>
    <groupId>io.vertx</groupId>
    <artifactId>vertx-core</artifactId>
    <version>3.5.0</version>
</dependency>
<dependency>
    <groupId>io.vertx</groupId>
    <artifactId>vertx-web-client</artifactId>
    <version>3.5.0</version>
</dependency>

试试这个：

Vertx.vertx().createHttpClient().get(new RequestOptions().setSsl(true).setHost("oauth.vk.com").setPort(443).setURI("/access_token"), 
            res -> {
                System.out.println("result: " + res.statusCode() + " " + res.statusMessage());
                res.bodyHandler(body -> {
                    System.out.println("result body: " + body.toString());
                });
            }).end();

Vert.x WebClient - 基于HTTPS的GET请求在Ubuntu服务器上因null原因而失败
