如何在Android中發佈數據？

Question

我找到了this使用http的PostData主題。但它不起作用。

怎麼了？

我還要求在manifestAndroid.permission.INTERNET。

public void postData() { 
    HttpClient httpclient = new DefaultHttpClient(); 
    HttpPost httppost = new HttpPost("http:/mysite.com/postTest.php"); 
    try { 
     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1); 
     nameValuePairs.add(new BasicNameValuePair("pw", "12456")); 
     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 
     // Execute HTTP Post Request 
     HttpResponse response = httpclient.execute(httppost); 
     tv.setText(response.toString()); 
    } catch (ClientProtocolException e) { 
     // 
    } catch (IOException e) { 
     // 
    } 
}

我的應用程序將使用此消息被終止： Unfortunately PostDataProject has stopped.

Answer 1

試試這個：

HttpResponse response = httpclient.execute(httppost); 
HttpEntity entity = responce.getEntity(); 
// convert stream to String 
BufferedReader buf = new BufferedReader(new InputStreamReader(entity.getContent())); 
StringBuilder sb1 = new StringBuilder(); 
String line = null; 
while ((line = buf.readLine()) != null) { 
sb1.append(line); 
} 
tv.setText(sb1.toString()); 

和u可以照片直接設置爲TextView的，如果數據僅供textvew或小：

tv.setText(EntityUtils.toString(response.getEntity())); 

，並使用此：

HttpPost httppost = new HttpPost("http://mysite.com/postTest.php"); 

代替

HttpPost httppost = new HttpPost("http:/mysite.com/postTest.php");

試圖讓響應與EntityUtilshttp://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/util/EntityUtils.html

tv.setText(EntityUtils.toString(response.getEntity()));
