What this article shares with you is PHP combined with Android client implementation query interactive example, the Java side is mainly implemented in three steps: first perform http request. Network request related operations, In the second step, use the execute method to send an HTTP GET request and return the HttpResponse object. In the third step, use the getEntity method to return the result. Friends in need can refer to

PHP server side:

function getids()
{
  $this->output->set_header(&#39;Content-Type: application/json; charset=utf-8&#39;);
  $jsonstr = &#39;&#39;;
  $pname = $pcallid = $pworkid = &#39;&#39;;
 
  if (isset($_GET[&#39;name&#39;])) {
    $pname = $_GET[&#39;name&#39;];
  }
 
  if (isset($_GET[&#39;callid&#39;])) {
    $pcallid = $_GET[&#39;callid&#39;];
  }
 
  if (isset($_GET[&#39;workid&#39;])) {
    $pworkid = $_GET[&#39;workid&#39;];
  }
 
  $this->load->model(&#39;wireid_model&#39;);
 
  $this->wireid_model->insertonly($pname, $pcallid);
 
  if ($pname == &#39;&#39; && $pcallid == &#39;&#39; && $pworkid == &#39;&#39;) {
    die();
  } else {
    $sqlstr = &#39;select * from twireid where 1=1 &#39;;
    if ($pname != &#39;&#39;) {
      $sqlstr = $sqlstr . " and GNAME=&#39;{$pname}&#39; ";
    } else
      if ($pcallid != &#39;&#39;) {
        $sqlstr = $sqlstr . " and GOLDCALLID=&#39;{$pcallid}&#39; ";
      } else
        if ($pworkid != &#39;&#39;) {
          $sqlstr = $sqlstr . " and GCARDID=&#39;{$pworkid}&#39; ";
        }
    $getdata = $this->wireid_model->getsql($sqlstr);
    // JSON_FORCE_OBJECT 防止出现 []
    $jsonstr = json_encode($getdata->result_array(), JSON_FORCE_OBJECT);
    echo $jsonstr;
  }
}

　Java Android side:

doAskTask = new Runnable() {
    @Override
    public void run() {
      // TODO
      // 在这里进行 http request.网络请求相关操作
      ggname = etname.getText().toString();
      ggworkid = etworkid.getText().toString();
      ggcallid = etcallid.getText().toString();
 
      String baseurl = ConfidDatas.askbaseurl;
      String askstr = "name=" + ggname + "&callid=" + ggcallid
          + "&workid=" + ggworkid;
      String result = null;
 
      HttpGet httpGet = new HttpGet(baseurl + askstr);
      // 第二步，使用execute方法发送HTTP GET请求，并返回HttpResponse对象
      HttpResponse httpResponse = null;
 
      try {
        httpResponse = new DefaultHttpClient().execute(httpGet);
      } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
      }
 
      Message msg = new Message();
      Bundle data = new Bundle();
 
      if (httpResponse.getStatusLine().getStatusCode() == 200) {
        // 第三步，使用getEntity方法活得返回结果
        try {
          result = EntityUtils.toString(httpResponse.getEntity());
          data.putString("value", result);
          data.putString("result", "isok");
          msg.setData(data);
          handler.sendMessage(msg);
        } catch (ParseException e) {
          // e.printStackTrace();
        } catch (IOException e) {
          // e.printStackTrace();
        }
      } else { // 错误
        data.putString("value", "");
        data.putString("result", "iserr");
        msg.setData(data);
        handler.sendMessage(msg);
      }
    }
  };
