HttpClient 获取状态码 [英] HttpClient get status code

问题描述

使用 Apache HttpClient 4.1.3 并尝试从 HttpGet 获取状态代码:

Using Apache HttpClient 4.1.3 and trying to get the status code from an HttpGet:

HttpClient client = new DefaultHttpClient();
HttpGet response = new HttpGet("http://www.example.com");
ResponseHandler<String> handler = new BasicResponseHandler();
String body = client.execute(response, handler);

如何从 body 中提取状态代码(202、404 等)? 或者，如果在 4.1.3 中有另一种方法可以做到这一点，是什么?

How do I extract the status code (202, 404, etc.) from the body? Or, if there's another way to do this in 4.1.3, what is it?

此外，我认为完美/良好的 HTTP 响应是 HttpStatus.SC_ACCEPTED，但也希望对此进行确认.提前致谢！

Also, I assume a perfect/good HTTP response is an HttpStatus.SC_ACCEPTED but would like confirmation on that as well. Thanks in advance!

推荐答案

尝试:

HttpResponse httpResp = client.execute(response);
int code = httpResp.getStatusLine().getStatusCode();

HttpStatus 应该是 200 ( HttpStatus.SC_OK )

The HttpStatus should be 200 ( HttpStatus.SC_OK )

(这个问题我读得太快了！)

(I've read too fast the problem!)

尝试:

GetMethod getMethod = new GetMethod("http://www.example.com");
int res = client.executeMethod(getMethod);

这应该可以解决问题！
