Java调用http接口（x-www-form-urlencoded）

try {
            String postURL = "http://118.24.*.*:8080/Dar_TWS_Service.asmx/GetFromStation";
            PostMethod postMethod = null;
            postMethod = new PostMethod(postURL) ;
            postMethod.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8") ;
            //参数设置，需要注意的就是里边不能传NULL，要传空字符串
            NameValuePair[] data = {
                    new NameValuePair("_ArgStr","*")
            };

            postMethod.setRequestBody(data);

            org.apache.commons.httpclient.HttpClient httpClient = new org.apache.commons.httpclient.HttpClient();
            int response = httpClient.executeMethod(postMethod); // 执行POST方法
            String result = postMethod.getResponseBodyAsString() ;
            System.out.println(response);
            System.out.println(result);
        } catch (Exception e) {
            // logger.info("请求异常"+e.getMessage(),e);
            throw new RuntimeException(e.getMessage());
