Android大侠进来看一下，标题是不是要长长长长长长长长长长长长长长长长啊！！！
本帖最后由 wudongfei1 于 2013-04-26 11:50:35 编辑 问题描述如下：
现在我想实现根据URL获取网页的html URL地址：http://nlp.xiaoi.com/robot/demo/wap/wap-demo.action?requestContent=why
我的实现如下
public class MainActivity extends Activity {
private Button getContent=null;
private HtmlUtil util=null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getContent=(Button) findViewById(R.id.getContent);
getContent.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
new Thread(new Runnable() {
@Override
public void run() {
util=new HtmlUtil();
String result=util.posturl("http://nlp.xiaoi.com/robot/demo/wap/wap-demo.action?requestContent=why");
System.out.println(result);
}
}).start();
}
});
}
}
public class HtmlUtil {
public String posturl(String url){
InputStream is = null;
String result = "";
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
e.printStackTrace();
return "Fail to establish http connection!"+e.toString();
}
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"utf-8"));
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
}catch(Exception e){
e.printStackTrace();
return "Fail to convert net stream!";
}
return result;
}
public InputStream streampost(String remote_addr){
URL infoUrl = null;
InputStream inStream = null;
try {
infoUrl = new URL(remote_addr);
URLConnection connection = infoUrl.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection)connection;
httpConnection.setRequestMethod("GET");
int responseCode = httpConnection.getResponseCode();
if(responseCode == HttpURLConnection.HTTP_OK){
inStream = httpConnection.getInputStream();
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return inStream;
}
//读取输入流中的数据，返回字节数组byte[]
public byte[] readInputStream(InputStream inStream) throws Exception{
//此类实现了一个输出流，其中的数据被写入一个 byte 数组
ByteArrayOutputStream outStream = new ByteArrayOutputStream();
// 字节数组
byte[] buffer = new byte[1024];
int len = 0;
//从输入流中读取一定数量的字节，并将其存储在缓冲区数组buffer 中
while ((len = inStream.read(buffer)) != -1) {
// 将指定 byte 数组中从偏移量 off 开始的 len 个字节写入此输出流
outStream.write(buffer, 0, len);
}
inStream.close();
//toByteArray()创建一个新分配的 byte 数组。
return outStream.toByteArray();
}
}
打印出来的信息如下

太诡异了 Android HTML
[解决办法]
屌丝 这都不会。。。
[解决办法]
那个URL是你的吗，访问来源或方式不同造成了返回结果不同？
[解决办法]
找到问题所在了。
你第一次打开浏览器，直接在地址栏输入“http://nlp.xiaoi.com/robot/demo/wap/wap-demo.action?requestContent=why”，返回的结果应该也是“<p class="wap_cn1"><b>我:</b>why</p> <p class="wap_cn2"></p>”。再次刷新的时候，才会有结果。
说明在cookie上面做了手脚。你参照“<script src="../../js/verify.js"></script>”这个js文件里面修改cookie的方式，在你的代码里面修改cookie。应该就行了。
