推荐答案

编码。您可以在HTTP标头中找到编码：

You have to set the correct encoding. You can find the encoding in the HTTP header:

Content-Type: text/html; charset=ISO-8859-1

这可能会在（X）HTML文档中被覆盖， a href =http://en.wikipedia.org/wiki/Character_encodings_in_HTML =nofollow> HTML字符编码

This may be overwritten in the (X)HTML document, see HTML Character encodings

我可以想象，你必须考虑许多不同的额外问题来解析网页错误免费。但是有不同的HTTP客户端库可用于Java，例如。 org.apache.httpcomponents 。代码将如下所示：

I can imagine that you have to consider many different additional issues to pars a web page error free. But there are different HTTP client libraries available for Java, e.g. org.apache.httpcomponents. The code will look like this:

DefaultHttpClient httpclient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://www.spiegel.de");

try
{
  HttpResponse response = httpclient.execute(httpGet);
  HttpEntity entity = response.getEntity();
  if (entity != null)
  {
    System.out.println(EntityUtils.toString(entity));
  }
}
catch (ClientProtocolException e) {e.printStackTrace();}
catch (IOException e) {e.printStackTrace();}

这是maven工件：

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.1.1</version>
  <type>jar</type>
  <scope>compile</scope>
</dependency>
