以下是我的代码。它返回空数组,如:Array ( ) 请检查下面的代码,让我知道要做出哪些更改。我正在创建一个JSON数组,并希望将其发布到网址。
String checkin = edit_message.getText().toString();
HttpClient httpclient = new DefaultHttpClient();
String httppostURL = "http:// ...";
HttpPost httppost = new HttpPost(httppostURL);
Log.v(TAG, "postURL: " + httppost);
JSONObject data1 = new JSONObject();
data1.put("merchant_id", "02");
data1.put("merchant_location_id", "03");
data1.put("user_id", "04");
data1.put("merchant_kiosk_id", "04");
data1.put("subscriber_phone", checkin);
JSONArray jsonArray = new JSONArray();
jsonArray.put(data1);
JSONObject data= new JSONObject();
data.put("data",jsonArray);
httppost.setHeader(HTTP.CONTENT_TYPE,"application/x-www-form-urlencoded;charset=UTF-8");
//httppost.setEntity(new UrlEncodedFormEntity(data , "UTF-8"));
StringEntity se= new StringEntity(data.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE,"application/json"));
httppost.setEntity(se);
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
if (resEntity != null) {
String responseStr = EntityUtils.toString(resEntity).trim();
Log.v(TAG, "Response: " + responseStr);
Log.i("TAG",""+response.getStatusLine().getStatusCode());
Toast.makeText(CheckinActivity.this, responseStr, Toast.LENGTH_LONG).show();
//you can add an if statement here and do other actions based on the response
}
edit_message.setText("");
//Toast.makeText(getBaseContext(),"Sent",Toast.LENGTH_SHORT).show();
Toast.makeText(CheckinActivity.this, "Data: " +data,Toast.LENGTH_LONG).show();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Throwable t) {
Toast.makeText(CheckinActivity.this, "Request failed: " + t.toString(),
Toast.LENGTH_LONG).show();
}
}
}
更新:
而不是
JSONObject data= new JSONObject();
data.put("data",jsonArray);
我用过:
List <NameValuePair> nvps = new ArrayList <NameValuePair>();
nvps.add(new BasicNameValuePair("data", data1.toString()));
httppost.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8));
更新2
我有像这样的json响应
{"msg":Successfully logged in,"status":1}
如果status = 1,我想做一些活动&amp;如果status = 0,我想做其他事情。怎么做到这一点?在哪里放置代码?提前致谢。

答案 1 :(得分:0)
使用JSON类进行解析,例如 您可以使用以下代码进行解析。
JSONObject mainObject = new JSONObject(responseStr);
int status = mainObject.getInt("status");
if(status==1){
//do something
}else{
//do something else
}
....
这是你想要的吗?请更新问题标题以获得您的确切需求。
