将数据从android发送到php时出错

Question

下面是我的应用程序的代码 sn-p 试图将数据发送到我的 php 地址。但它出现了一个错误。 Ans 当我检查我的 php 服务器时，它没有显示出来。这是下面的代码 sn-p：

 public void sendData() {
    String ip = getIpAddress();
 HttpClient httpclient = new DefaultHttpClient();
 HttpPost httppost = new HttpPost("http://mysamplephp.php?ip=" + ip + "&date=" + formattedDate + "&appname=amigosmexican"+ "&appid="+ android_id);
    try{
        List<BasicNameValuePair> deviceinfo = new ArrayList<BasicNameValuePair>(3);
         deviceinfo.add(new BasicNameValuePair("id", android_id));
         deviceinfo.add(new BasicNameValuePair("date", formattedDate));
         deviceinfo.add(new BasicNameValuePair("ip", ip));
         httppost.setEntity(new UrlEncodedFormEntity(deviceinfo));  

         HttpResponse response = httpclient.execute(httppost);

         InputStream is = response.getEntity().getContent();
         BufferedInputStream bis = new BufferedInputStream(is);
         ByteArrayBuffer baf = new ByteArrayBuffer(20);
         Log.i("postData", response.toString());
         int current = 0;

         while((current = bis.read()) != -1){
             baf.append((byte)current);
         }



    } catch (ClientProtocolException e) {

    } catch (IOException e) {
        Log.e("log_tag", "Error in http connection ",e);
         }
    }

}

错误是：

编辑： sn-p 获取外部ip：

 public String getIpAddress() {
try {
for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
    NetworkInterface intf = en.nextElement();
    for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
        InetAddress inetAddress = enumIpAddr.nextElement();
        if (!inetAddress.isLoopbackAddress()) {
            return inetAddress.getHostAddress().toString();
        }
    }
}
} catch (SocketException ex) {
Log.e("LOG", ex.toString());
}
return null;
}

当您在 List params 中传递参数时，无需将它们写在 url 中，

以这种方式尝试您的代码，

public void sendData() {
String ip = getIpAddress();
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://mysamplephp.php");
try{
    List<BasicNameValuePair> deviceinfo = new ArrayList<BasicNameValuePair>(3);
     deviceinfo.add(new BasicNameValuePair("id", android_id));
     deviceinfo.add(new BasicNameValuePair("date", formattedDate));
     deviceinfo.add(new BasicNameValuePair("ip", ip));
     httppost.setEntity(new UrlEncodedFormEntity(deviceinfo));  

     HttpResponse response = httpclient.execute(httppost);

     InputStream is = response.getEntity().getContent();
     BufferedInputStream bis = new BufferedInputStream(is);
     ByteArrayBuffer baf = new ByteArrayBuffer(20);
     Log.i("postData", response.toString());
     int current = 0;

     while((current = bis.read()) != -1){
         baf.append((byte)current);
     }



} catch (ClientProtocolException e) {

} catch (IOException e) {
    Log.e("log_tag", "Error in http connection ",e);
     }
}

试试这个，它会起作用的。更多详情请查看此演示代码
