java访问url
我在浏览器访问
http://lab.3haku.net/f/do?phone=15855022871&pwd=liu15855022871&to=15855022871&u=utf8&msg=game over
手机能收到 game over
但是我copy来的程序只能接受到game为什么呀?怎么改。。。
代码如下;import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.net.URLConnection;
public class Fetion {
public static void main(String[] args) {
String urlStr = "http://lab.3haku.net/f/do?phone=15855022871&pwd=liu15855022871&to=15855022871&u=utf8&msg=game over";
URL url;
try {
url = new URL(urlStr);
URLConnection URLconnection = url.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection)URLconnection;
int responseCode = httpConnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
System.err.println("成功");
InputStream urlStream = httpConnection.getInputStream();
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlStream));
String sCurrentLine = "";
String sTotalString = "";
while ((sCurrentLine = bufferedReader.readLine()) != null) {
sTotalString += sCurrentLine;
}
System.err.println( sTotalString);
}
}catch (Exception e) {
// TODO Auto-generated catch blockeb
e.printStackTrace();
}
}
}
[解决办法]
参数中有空格的原因
传参前用java.net.URLEncoder.encode对参数进行编码或是把空格替换成%20
[解决办法]
楼上答案很对！
String urlStr = "http://lab.3haku.net/f/do?phone=15855022871&pwd=liu15855022871&to=15855022871&u=utf8&msg=game over";
