从 Eclipse 调用 Rest API 时连接超时

Question

帮帮我！我有一个 restful API link，我使用 Postman 工具调用成功，但是当我在 eclipse 上编写一个 Restful 客户端时，它失败了。我尝试关闭代理，但没有成功。

public class JersyGetClient {

    public static void main(String[] args) {
        String url = "https://abc.custhelp.com/services/rest/connect/v1.4/accounts";
        String name = "thai.hoangan";
        String password = "123456a@";
        String authString = name + ":" + password;
        String authStringEnc = new BASE64Encoder().encode(authString.getBytes());
        System.out.println("Base64 encoded auth string: " + authStringEnc);
        Client restClient = Client.create();
        WebResource webResource = restClient.resource(url);
        ClientResponse resp = webResource.accept("application/json")
                .header("Authorization", "Basic " + authStringEnc)
                .header("OSvC-CREST-Application-Context", "asd")
                .get(ClientResponse.class);
        if (resp.getStatus() != 200) {
            System.err.println("Unable to connect to the server");
        }
        String output = resp.getEntity(String.class);
        System.out.println("response: " + output);
    }
}

输出：

哦，我解决了，补充一下：

    System.setProperty("https.proxyHost", "proxytest.vcb");
    System.setProperty("https.proxyPort", "8080");
