如何向HttpClient发送发布请求

Question

有谁知道如何使用HttpClient库在Java Eclipse中使用发布请求更新页面？目前，这是我，但是当我 执行它，我得到找不到网页错误：

public void update() { 
    HttpClient httpclient = new DefaultHttpClient(); 
    HttpPost httppost = new HttpPost("http://examplepage.xml"); 
    try { 
     // Add your data 
     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2); 
     nameValuePairs.add(new BasicNameValuePair("_action", "<BasicPage><title>New Title</title></BasicPage>")); 
     nameValuePairs.add(new BasicNameValuePair("_method", "post")); 
     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
     // Execute HTTP Post Request 
     HttpResponse response = httpclient.execute(httppost); 
     HttpEntity entity = response.getEntity(); 
     String info = (""+EntityUtils.toString(entity)); 
     System.out.println(info); 
     System.out.println(response.getEntity().getContent()); 
     System.out.println(response); 
    } catch (ClientProtocolException e) { 
     // TODO Auto-generated catch block 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
    } 
}

您的代码看起来不错。检查页面URI或别名“examplepage.xml”实际上是否存在或映射。检查它是否可以接受POST请求。
