Apache HttpClient in Java, instream.toString = org.apache.http.conn.EofSensorInputStream
提问by Dominik
I am GETting a page with Apache HttpClient and I want to store the server reply's http body into a string so I can then manipulate this string and print it to the console.
我正在使用 Apache HttpClient 获取页面，并且我想将服务器回复的 http 正文存储到一个字符串中，以便我可以操作该字符串并将其打印到控制台。
Unfortunately when running this method I get this message back:
不幸的是，在运行此方法时，我收到此消息：
17:52:01,862 INFO Driver:53 - fetchPage STARTING
17:52:07,580 INFO Driver:73 - fetchPage ENDING, took 5716
org.apache.http.conn.EofSensorInputStream@5e0eb724
The fetchPage Class:
fetchPage 类：
public String fetchPage(String part){
log.info("fetchPage STARTING");
long start = System.currentTimeMillis();
String reply;
String searchurl = URL + URL_SEARCH_BASE + part + URL_SEARCH_TAIL;
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(searchurl);
HttpResponse response;
try {
response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
InputStream instream = entity.getContent();
int l;
byte[] tmp = new byte[2048];
while ((l = instream.read(tmp)) != -1) {
}
long elapsedTimeMillis = System.currentTimeMillis()-start;
log.info("fetchPage ENDING, took " + elapsedTimeMillis);
reply = instream.toString();
System.out.println(reply);
return reply;
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}

You are calling the toStringon the InputStreamafter it has already read through. You need to create your string from the byte arrays. The simpler way to get the String version of the content is to use the EntityUtils.toString(HttpEntity)
您呼叫的toString在InputStream后它已通过已经被读取。您需要从字节数组创建字符串。获取内容的 String 版本的更简单方法是使用EntityUtils.toString(HttpEntity)
The exact implementation would look like:
确切的实现如下所示：
import org.apache.http.util.EntityUtils;
public String fetchPage(String part){
log.info("fetchPage STARTING");
long start = System.currentTimeMillis();
String reply;
String searchurl = URL + URL_SEARCH_BASE + part + URL_SEARCH_TAIL;
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(searchurl);
HttpResponse response;
try {
response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null) {
return EntityUtils.toString(entity);
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
