问题描述

我正在探索Android的扫描SSID和RSSI，我可以做到这一点，但是现在我想将数据发送到服务器，所以我探索了我在Code

下找到的.

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://101.34.45.45/rawData");

    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
        nameValuePairs.add(new BasicNameValuePair("userId", "00-22-68-E8-EC-F1"));
        nameValuePairs.add(new BasicNameValuePair("timestamp", "2010-07-01 11:11:11"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = httpclient.execute(httppost);
        textView.setText(response.toString());

    } catch (ClientProtocolException e) {
    } catch (IOException e) {
    }

但是现在我在添加多WiFi数据时遇到问题，格式应如下

http://101.34.45.45/rawdata?data?data?data?data?data? Guest1"，" Timestamp":" 2010-07-01 08:58:23"，" WiFi":[{" ssid":" guest"，" rssi":" 40"}，{guest {guest'ssid":":"" "，" rssi":":" 80"}]}，

因此，如何为WiFi参数做，任何人都可以提供帮助，我仍在尝试一些品种，

谢谢

推荐答案

我建议您切换到JSON将数据发送到服务器. Google gson 最容易用于发送和解析JSON.

{"userId":"guest1","timestamp":"2010-07-01 08:58:23","wifi":[{"ssid":"guest","rssi":"40"},{"ssid":"guest1","rssi":"80"}]}

您应该使用具有JSON数组的JSON对象作为其项目之一. JSON数组依次包含另一个JSON对象.

如果您使用的是Google Gson，则应为此构建类层次结构.这是您应该如何做的.

Class data{

 String userId;
 String timestamp;
 Wifi wifi;
}

Class Wifi{

 String ssid;
 int rssi;
}

您可以检查在这里对于Android中解析JSON的类似问题的示例代码.

this 也可能有用.

I'm exploring to scan ssid and rssi from android and I'm able to do it, but now i have want send the data to the server, so i explore i found below code

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("http://101.34.45.45/rawData");

    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
        nameValuePairs.add(new BasicNameValuePair("userId", "00-22-68-E8-EC-F1"));
        nameValuePairs.add(new BasicNameValuePair("timestamp", "2010-07-01 11:11:11"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        HttpResponse response = httpclient.execute(httppost);
        textView.setText(response.toString());

    } catch (ClientProtocolException e) {
    } catch (IOException e) {
    }

but now i'm having problem when add multi wifi data, the format should as below

http://101.34.45.45/rawData?data={"userId":"guest1","timestamp":"2010-07-01 08:58:23","wifi":[{"ssid":"guest","rssi":"40"},{"ssid":"guest1","rssi":"80"}]},

so how can done for the wifi parameter, can anyone help, I'm still trying for few varieties,

thanks

推荐答案

I would recommend you to switch to JSON for sending data to the server. Google gson is easiest to use to send and parse JSON.

{"userId":"guest1","timestamp":"2010-07-01 08:58:23","wifi":[{"ssid":"guest","rssi":"40"},{"ssid":"guest1","rssi":"80"}]}

You should use a JSON object having a JSON array as one of its items. The JSON array in turn contains another json object.

If you are using Google GSON, you should build a class hierarchy for the same. Heres how you should do the same.

Class data{

 String userId;
 String timestamp;
 Wifi wifi;
}

Class Wifi{

 String ssid;
 int rssi;
}

You can check here for a sample code on a similar problem on parsing json in android.

This may be useful too.
