java - Vertx WebClient 下载文件

Question

尝试从此 url 下载文件使用 Vertx WebClient 但不起作用。我在这里遗漏了什么吗？

    // Create the web client and enable SSL/TLS with a trust store
    WebClient client = WebClient.create(vertx,
            new WebClientOptions()
                    .setSsl(false)
                    .setTrustAll(true)
                    .setDefaultPort(80)
                    .setKeepAlive(true)
                    .setDefaultHost("www.nasdaq.com"));


    client.get(80, "www.nasdaq.com", "/screening/companies-by-industry.aspx")
            .addQueryParam("exchange", "NASDAQ")
            .addQueryParam("render", "download")
            .putHeader("content-type","text/csv")
            .as(BodyCodec.string())
            .send(ar -> {
                if (ar.succeeded()) {

                    // HttpResponse<Void> response = ar.result();

                    System.out.println("Received response with status code");
                } else {
                    System.out.println("Something went wrong " + ar.cause().getMessage());
                }
            });

既然我弄清楚了，就在这里回答这个问题。

问题是网站重定向到不同的下载网址，但 Vertx WebClient future 未完成。它至少应该返回一个状态代码 302 来表明原因 - 叹息!
