救救我!我有一个Restful API链接,我使用Postman工具调用成功,但是当我在Eclipse上编译一个Restful客户端时,它失败了。我尝试关闭代理服务器,但未成功。

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:

  

线程“ main”中的com.sun.jersey.api.client.ClientHandlerException异常:

哦,我解决了,只需添加:

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