Question

我正在通过防火墙使用以下代码进行REST Web服务调用：

try {
    String url="http://testcall.us:1300/abc/testapi/json/method1"; //dummy url
    Client client = Client.create();
    WebResource webResource = client.resource(url);

    ClientResponse response = webResource.accept("application/json")
        .type(MediaType.APPLICATION_JSON)
        .header("content-type", "application/json")
        .get(ClientResponse.class);                         

    System.out.println("response.getStatus" + response.getStatus());
} catch (Exception e) {
    logger.error("Error making webservice call", e);
}

该代码在我的本地Windows环境中运行良好。但是，当我从另一个linux服务器发出相同的请求时，出现以下异常：

com.sun.jersey.api.client.ClientHandlerException: java.io.EOFException: Response had end of stream after 0 bytes
at com.sun.jersey.client.urlconnection.URLConnectionClientHandler.handle(URLConnectionClientHandler.java:155)

at com.sun.jersey.api.client.WebResource.access$200(WebResource.java:74)
.......

当我从相同的网址（使用不同的方法）发出另一个POST请求时，

try {
    String url="http://testcall.us:1300/abc/testapi/json/method2"; //dummy url
    Client client = Client.create();

    WebResource webResource = client
            .resource(url);                    

    String input = "{\"Id\":" + String.valueOf(id) + ",\"Status\":" + null + "}";

    ClientResponse response = webResource.type("application/json")
            .header("Environment", "dev")
            .accept("application/json")
            .post(ClientResponse.class, input);

    if (response.getStatus() != 200 && response.getStatus() != 201) {
        logger.error("REST ws call failed. HTTP error code : " + response.getStatus());
    }

    System.out.println("Output from Server .... \n");
    String output = response.getEntity(String.class);
    System.out.println(output);

} catch (Exception e) {
    logger.error("Error submitting request", e );
}

我收到以下异常：

<Error submitting request

在我的本地环境中，该方法再次可以很好地工作。在另一个环境中正常工作时，相同的URL引发异常的原因可能是什么？据我所知，防火墙规则已被批准用于Linux环境。预先感谢您提供任何见解。

更新我刚刚发现为此URL提交的防火墙规则包含“ https”而不是“ http”。但是据我所知，防火墙并不关心它是“ http”还是“ https”。我没有访问Linux机器的权限，因此无法检查是否可以使用那里的网址获得响应：(。

更新在腻子上使用'curl'命令，我能够在Linux服务器上得到响应。这是否意味着java / weblogic配置中缺少某些内容？

REST调用抛出java.io.EOFException
