HTML contect從我的方法來讀取從頁面不同

http://www.centerplex.com.br/

我的方法

public String getHtml(String urlStr, String charset) throws Exception { 
    System.setProperty("http.proxyHost", "XXX.XX.X.XXX"); 
    System.setProperty("http.proxyPort", "XXXX"); 
    URL url = new URL(urlStr); 
    URLConnection conn = url.openConnection(); 
    InputStream is = url.openStream(); 
    InputStreamReader isr = new InputStreamReader(is, charset); 
    BufferedReader br = new BufferedReader(isr); 
    String linha = br.readLine(); 
    String html = ""; 
    while (linha != null) { 
     System.out.println("" + linha); 
     html += linha; 
     linha = br.readLine(); 
    } 

    return html; 
}

這種方法會奏效到其他頁面，但給我一個不完整的HTML。

我看到了大量的JavaScript通過該頁面，但我不知道它是否具有影響力

下面是HTML返回從這個頁面

有我的形成是其實現方法具沒有bug在你的代碼中。看起來像服務器端返回不同的內容，根據要求。嘗試通過HttpClient庫進行請求並模仿瀏覽器請求：

import java.io.IOException; 
import org.apache.commons.io.IOUtils; 
import org.apache.http.client.methods.CloseableHttpResponse; 
import org.apache.http.client.methods.HttpPost; 
import org.apache.http.impl.client.HttpClientBuilder; 

public class NewClass { 
    public static void main(String[] args) throws IOException { 
      String HOST = "www.centerplex.com.br"; 
      HttpPost post = new HttpPost("http://"+HOST+"/"); 
      post.setHeader("ProtocolVersion ", "HTTP/1.1"); 
      post.setHeader("Host",HOST); 
      post.setHeader("Connection","keep-alive"); 
      post.setHeader("Accept", "*/*"); 
      post.setHeader("User-Agent","Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.86 Safari/537.36"); 
      post.setHeader("DNT","1"); 
      post.setHeader("Accept-Encoding","gzip, deflate, sdch"); 
      post.setHeader("Accept-Language","en-GB,en-U3;q=0.8,en;q=0.6"); 
      post.setHeader("Cookie","_gat=l; _ga=GAl.2.904730494.1449539712"); 
      post.setHeader("HeaderEnd","CRLF"); 
      CloseableHttpResponse response = HttpClientBuilder.create().build().execute(post); 
      String responseText = IOUtils.toString(response.getEntity().getContent(), "UTF-8"); 
      System.out.println(responseText); 
    } 
}
