如何从JSON链路数据？ [英] How to retrieve data from json link?

问题描述

我可以检索与正常的JSON链路数据，但我有一个链接，这是密码保护。

比我如何与我的Andr​​oid应用程序连接呢？

请帮帮我吗？
在code为连接到我使用正常的链接在这里。

 的ArrayList＆LT;＆的NameValuePair GT; namevaluepairs中=新的ArrayList＆LT;＆的NameValuePair GT;（）;
    nameValuePairs.add（新BasicNameValuePair（track_date，2011-08-09））;
    nameValuePairs.add（新BasicNameValuePair（tracker_user_id，+ 374））;    尝试{
        HttpClient的HttpClient的=新DefaultHttpClient（）;
        HttpPost httppost =新HttpPost（
                http://abovestress.com/app_stress/fetch_all_detail.php?task=fetchtimefromdateanduserid&）;
        httppost.setEntity（新UrlEn codedFormEntity（namevaluepairs中））;
        HTT presponse响应= httpclient.execute（httppost）;
        HttpEntity实体= response.getEntity（）;
        是= entity.getContent（）;
    }赶上（例外五）{
        Log.e（log_tag，在HTTP连接错误+ e.toString（））;
    }
    //响应转换为字符串
    尝试{
        读者的BufferedReader =新的BufferedReader（新的InputStreamReader（
                是，ISO-8859-1），8）;
        StringBuilder的SB =新的StringBuilder（）;
        串线= NULL;
        而（（行= reader.readLine（））！= NULL）{
            sb.append（行+\\ n）;
        }
        is.close（）;
        结果= sb.toString（）;
        Log.v（log_tag，追加字符串+结果）;
    }赶上（例外五）{
        Log.e（log_tag，错误转换结果+ e.toString（））;
    }    //解析JSON数据
    尝试{
        JSONArray jArray =新JSONArray（结果）;
        的for（int i = 0; I＆LT; jArray.length（）;我++）{
            JSONObject的json_data = jArray.getJSONObject（I）
            fetchsosfromID.add（json_data.getString（track_time））;
        }
        Log.v（log_tag，daily_data+ fetchsosfromID）;    }赶上（JSONException E）{
        Log.e（log_tag，错误分析数据+ e.toString（））;
    }
}
公共布尔isTimeExistSos（）{    返回false;
}
 

解决方案

尝试将此添加到您的的HttpClient ：

  //创建用户名和放大器;密码
字符串username =的uname;
字符串密码=passwd文件;
//创建连接客户端
DefaultHttpClient客户端=新DefaultHttpClient（PARAMS）;
用于连接客户端//凭证集
client.getCredentialsProvider（）
            .setCredentials（
新AuthScope（NULL，-1），新UsernamePasswordCredentials（用户名，密码））;
 

I can retrieve data from normal json link But I have one link which is password protected.

Than How can I connect this with my Android application?

please help me ? The code for connect to normal link I am using is here.

ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
    nameValuePairs.add(new BasicNameValuePair("track_date", "2011-08-09"));
    nameValuePairs.add(new BasicNameValuePair("tracker_user_id", "" + 374));

    try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost(
                "http://abovestress.com/app_stress/fetch_all_detail.php?task=fetchtimefromdateanduserid&");
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
    } catch (Exception e) {
        Log.e("log_tag", "Error in http connection " + e.toString());
    }
    // convert response to string
    try {
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                is, "iso-8859-1"), 8);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        result = sb.toString();
        Log.v("log_tag", "Append String " + result);
    } catch (Exception e) {
        Log.e("log_tag", "Error converting result " + e.toString());
    }

    // parse json data
    try {
        JSONArray jArray = new JSONArray(result);
        for (int i = 0; i < jArray.length(); i++) {
            JSONObject json_data = jArray.getJSONObject(i);
            fetchsosfromID.add(json_data.getString("track_time"));
        }
        Log.v("log_tag", "daily_data " + fetchsosfromID);

    } catch (JSONException e) {
        Log.e("log_tag", "Error parsing data " + e.toString());
    }
}
public boolean isTimeExistSos(){

    return false;
}

解决方案

try to add this to your HttpClient:

//create username & password
String username = "uname";
String password = "passwd";
// create connection client
DefaultHttpClient client = new DefaultHttpClient(params);
// set credentials for connection client
client.getCredentialsProvider()
            .setCredentials(
new AuthScope(null, -1), new UsernamePasswordCredentials(username,password));
