android中的httpclient使用

用php搭建了个简单的服务器端，然后在android中使用httpclient来调用．

String httpurl="http://192.168.1.100/http/httptest.php?para=hello"; HttpGet httpGet=new HttpGet(httpurl); HttpParams httpParameters = new BasicHttpParams();// Set the timeout in milliseconds until a connection is established. HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);// Set the default socket timeout (SO_TIMEOUT) // in milliseconds which is the timeout for waiting for data. HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket); HttpClient httpclient = new DefaultHttpClient(httpParameters); try{ HttpResponse httpResponse=httpclient.execute(httpGet); if (httpResponse.getStatusLine().getStatusCode()==HttpStatus.SC_OK){ String strResult=EntityUtils.toString(httpResponse.getEntity()); txtHello.setText(strResult); mWebView.loadUrl(httpurl); } else{ txtHello.setText("no response"); } }catch(IOException e){ e.printStackTrace(); }

刚开始发现在执行httpclient.execute的时候就没有了响应，程序没有继续执行，也没有报告错误，后来一查，需要加入相应的权限才可以：

<uses-permission android:name="android.permission.INTERNET" />

这样就可以正确的返回信息了．

接下来的问题是返回的信息中有中文，在android中显示为乱码，估计是服务器端的问题，于是在php中加入了编码：

header("Content-Type: text/html;charset=utf-8");

可以正常显示了．
