Question

我使用http找到了PostData的this主题。但它不起作用。

怎么了？

我还要求Android.permission.INTERNET中的manifest。

    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) {
        //
    }
}

修改

我的申请将以此消息终止： Unfortunately PostDataProject has stopped.

Answer 1

试试这个：

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());

如果数据仅用于textview或小型，则可以直接设置为textview：

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

并使用此：

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

而不是

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

Answer 2

尝试通过EntityUtils http://hc.apache.org/httpcomponents-core-ga/httpcore/apidocs/org/apache/http/util/EntityUtils.html

获得回复

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

如何在Android中发布数据？
