如何在java中获取httpPut的响应代码

Question

我正在使用httpPut到java，我想在执行命令后获取响应代码。它给了我什么是＆＃34;响应体＆＃34;是：

HTTP/1.1 200 OK [Cache-Control: no-cache, no-store, must-revalidate, Pragma: no-cache, Expires: Thu, 01 Jan 1970 00:00:00 GMT, Content-Type: application/json, Transfer-Encoding: chunked, Server: Jetty(8.1.8.v20121106)]

但我只想要200！不是整件事。有帮助吗？ 这是我的代码：

String url = "http://localhost:80/api/clients/";
    String clientID = "1234";

    httpclient = new DefaultHttpClient();
    HttpPut putRequest = new HttpPut(url + clientID);
    putRequest.setHeader("Content-Type", "application/x-www-form-urlencoded");
    putRequest.setHeader("Charset", "UTF-8");

    System.out.println(putRequest);
    // Add your data
    putRequest.setEntity(new StringEntity(clientID, "UTF-8"));
    HttpResponse responseBody = httpclient.execute(putRequest);

Answer 1

HTTPResonse有一个名为getStatusLine()的方法，它返回StatusLine对象。

StatusLine有一个方法getStatusCode()

所以，你需要写的只是

HttpResponse responseBody = httpclient.execute(putRequest);
int resultCode = responseBody.getStatusLine().getStatusCode();//200 in your case

Answer 2

responseBody.getStatusLine().getStatusCode()应该为您提供请求的响应代码。
