i want to send data from android application to local server (PHP) but it doesn't work
this is my code (it is work with remote server ):
String path ="http://localhost/sd.php";
HttpClient client = new DefaultHttpClient();
HttpConnectionParams.setConnectionTimeout(client.getParams(), 100000);
HttpResponse response;
JSONObject json = new JSONObject();
try {
HttpPost post = new HttpPost(path);
json.put("im", 999);
json.put("cTime", 12);
Log.i("jason Object", json.toString());
post.setHeader("json", json.toString());
StringEntity se = new StringEntity(json.toString());
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE,"application/json"));
post.setEntity(se);
response = client.execute(post);
} catch (Exception e) {
Object n=e.getStackTrace();
Toast.makeText( getApplicationContext(),n.toString(),Toast.LENGTH_SHORT).show();
}
i thing the wrong in the address http://localhost/sd.php
pleas help me to find a solution to this problem
You need the IP address of the server. Localhost from the app is the phone.

Both my laptop and my Android device is connected to the same WiFi. and I am trying to send data from my phone to the PHP webservice. But I can't get it work. What is the problem?
IP of my laptop: 192.168.0.10
IP of my phone: 192.168.0.9
I am listening from port80: ie:
HttpPost httppost = new HttpPost("http://192.168.0.10:80");
Following are the code of my PHP file:
<?php
$get = json_encode($_POST["req"]);
// Get data from object
$name = $get->req; // Get name you send
$age = $get->req; // Get age of user
?>
and below are my android code. Which part i'm doing wrongly? Please help!
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.0.10:80");
try {
JSONObject jsonobj = new JSONObject();
jsonobj.put("name", "Jensen");
jsonobj.put("age", "22");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("req", jsonobj.toString()));
Log.e("mainToPost", "mainToPost" + nameValuePairs.toString());
// Use UrlEncodedFormEntity to send in proper format which we need
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
HttpResponse response = httpclient.execute(httppost);
Another thing, I have tried sending the data over too. I will need to press a button then the data will be passed. After I press the button, this is what I got (I'm connecting my phone through ADB):
I'm trying to retrieve data from mysql database located on a remote server through php into android. This worked fine while running in localhost. But when it is in remote server, I receive HTML codes instead of JSON response from server. I tried pasting the url (http://ksos.0fees.us/pgm_list.php?day=1&hall=A) in browser which resulted in correct JSON output. The HTML response is shown below.
<html><body>
<script type="text/javascript" src="/aes.js" ></script>
<script>function toNumbers(d)
{var e=[];
d.replace(/(..)/g,function(d){e.push(parseInt(d,16))});
return e
}
function toHex()
{for(var d=[],d=1==arguments.length&&arguments[0].constructor==Array?arguments[0]:arguments,e="",f=0;f<d.length;f++)
e+=(16>d[f]?"0":"")+d[f].toString(16);
return e.toLowerCase()
}
var a=toNumbers("f655ba9d09a112d4968c63579db590b4"),b=toNumbers("98344c2eee86c3994890592585b49f80"),c=toNumbers("5cb1c0309e553acda177d912f21ac485");

Following is my request to server for getting response
public String makeServiceCall(String url, int method, List<NameValuePair> params){
try{
DefaultHttpClient httpclient = new DefaultHttpClient();
HttpEntity httpentity = null;
HttpResponse httpresponse = null;
if (method == POST) {
HttpPost httppost = new HttpPost(url);
httppost.setHeader("User-Agent", ua);
httppost.setHeader("Accept", "application/json");
if(params!=null){
httppost.setEntity(new UrlEncodedFormEntity(params));
}
httpresponse = httpclient.execute(httppost);
} else if(method == GET){
if(params!=null){
String paramString = URLEncodedUtils.format(params, "utf-8");
url += "?" + paramString;
}
HttpGet httpget = new HttpGet(url);
// HttpPost httppost = new HttpPost(url);
httpget.setHeader("User-Agent", ua);
httpget.setHeader("Accept", "application/json");
httpresponse = httpclient.execute(httpget);
}
httpentity = httpresponse.getEntity();
is = httpentity.getContent();
}catch(UnsupportedEncodingException e){
e.printStackTrace();
}catch (ClientProtocolException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"UTF-8"),8);
// 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();
response = sb.toString();
}catch(Exception e){
Log.e("Buffer Error", "Error : "+e.toString());
}
return response;
}
I've tried by setting and not setting setHeader for user agent.
The php part looks as follows:
$q=mysql_query("SELECT ...........");
if(!empty($q)){
while($row=mysql_fetch_assoc($q))
$pgmlist[]=$row;
$response["pgmlist"] = $pgmlist;
echo json_encode($response);
}
else{
$response["success"] = 0;
$response["message"] = "No record found";
echo json_encode($response);
}
Atlast found solution...
The issue was not with the android or php part. It was the problem with the server. The hosting site which I used, sends cookies to client side which is not handled inside android but is automatically handled by browsers. I used to another hosting site where cookies are not involved and got the needed json output.
I spent a long time to understand and solve the problem.
Firstly, we need to understand that 0fess hosting has anti bot technique which blocks the calls from (none-browser) clients. The main idea of this technique is using a javascript script that checks if the request is coming from a normal web browser then the script encrypts the IP and sets a cookie with key __test and value of the encrypted IP.
To solve such a problem we need to run a webview inside our application and request any page from the our 0fees site. then we can intercept the response and get the cookie. after that, we can use this cookie as a request header in our http rest requests.
This is a sample code
WebView browser=new WebView(getContext());
browser.getSettings().setJavaScriptEnabled(true);
browser.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url){
final String cookies = CookieManager.getInstance().getCookie(url);
Log.d("any", "All the cookies by me in a string:" + cookies);
HttpPost httppost = new HttpPost("http://ksos.0fees.us/pgm_list.php");
httppost.setHeader("Accept", "application/json");
httppost.setHeader("Cookie", cookies);
//continue your request paramters
}
}
);
browser.loadUrl("http://ksos.0fees.us/");
Hi i am quite new in Android client php server. I follow some tutorial for post and response variable by JSON but this reponse error. Value of type java.lang.String cannot be converted to JSONObject.
The JSON post is success but the response is error.
Android code:
HttpConnectionParams.setConnectionTimeout(httpParameters, 15000);
HttpConnectionParams.setSoTimeout(httpParameters, 15000);
HttpClient httpclient = new DefaultHttpClient(httpParameters);
HttpPost httppost = new HttpPost("http://192.168.1.1/databastest/login.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
String result = EntityUtils.toString(entity);
// Create a JSON object from the request response
JSONObject jsonObject = new JSONObject(result);
//Retrieve the data from the JSON object
resultLoging = jsonObject.getString("ResultArray");
}catch (Exception e){
Log.e("ClientServerDemo", "Error:", e);
exception = e;
}
return true;
}
#Override
protected void onPostExecute(Boolean valid){
//Update the UI
Toast.makeText(mContext, resultLoging, Toast.LENGTH_LONG).show();
if(exception != null){
Log.i("Error",exception.getMessage());
Toast.makeText(mContext, exception.getMessage(), Toast.LENGTH_LONG).show();
}
}
php code
mysqli_query($con,"INSERT INTO usersacc
(phone, password) VALUES('$pho', '$pass')");
#Build the result array (Assign keys to the values)
$result_data = array(
'ResultArray' => 'success',
);
#Output the JSON data
echo json_encode($result_data);
The insert is successful but the result not done.
Replace this your code with this may work.Get the response from server as Object not as String.
Object result = EntityUtils.toString(entity);
JSONObject jsonObject = new JSONObject(result.toString());
resultLoging = jsonObject.getString("ResultArray");
I am sending JSONObject to the server using below code. But I am unable to receive it in server side using PHP . Can anyone please guide me how to receive it.
public void sendStatus(JSONObject object) {
HttpParams myParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(myParams, 10000);
HttpConnectionParams.setSoTimeout(myParams, 10000);
HttpClient httpclient = new DefaultHttpClient(myParams);
String jsonString = object.toString();
try {
HttpPost httppost = new HttpPost(url);
httppost.setHeader("Content-type", "application/json");
StringEntity se = new StringEntity(jsonString);
se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
httppost.setEntity(se);
HttpResponse response = httpclient.execute(httppost);
String temp = EntityUtils.toString(response.getEntity());
} catch (ClientProtocolException e) {
} catch (IOException e) {
}
}
I have already done it using name value pair using following code
$datastring = trim($headers['name']);
But as in the above code I am only getting the JSONObject but not any tag. So please anyone can help me or provide me any useful link then I will be grateful.
My JSONObject format is as belos=w
{
"user_id": "123456",
"Objects": [
{
"name": "AAA"
},
{
"name": "BBB"
},
{
"name": "CCC"
},
{
"name": "DDD"
}
]
}
To send the JSON as string from the Android device you can send it as a POST param:
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("json_string", jsonString));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
or if you want to send it as a header:
httppost.addHeader("json_string", jsonString)
However, a header has a maximum length so I'd recommend sending it as POST params
In order to work with a JSON object in PHP, you must decode it first into a associative array doing the following
$jsonAsArray = json_decode($jsonAsString, true)
Afterward, you'll be able to access JSON properties like:
$jsonAsArray['user_id'] // 123456
$jsonAsArray['Objects'][1]['name'] // BBB
Seems Android app sends the JSON Object without problems but when i receive i get a :
"Notice: undefined index"
The Code that sends the Object is here :
public void sendJson( String name1, String name2 ) throws JSONException {
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://example.com/JSON_FOLDER/JSON2/parseData.php");
HttpResponse response;
JSONObject json = new JSONObject();
try {
json.put("name1", name1);
json.put("name2", name2);
StringEntity se = new StringEntity(json.toString());
se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
httppost.getParams().setParameter("json", json); // new code
//Execute HTTP POST request
httppost.setEntity(se);
response = httpclient.execute(httppost);
if( response != null ) {
str = inputStreamToString(response.getEntity().getContent()).toString();
Log.i("DATA", "Data send== " + str );
}
} catch ( ClientProtocolException e ) {
e.printStackTrace();
} catch ( IOException e ) {
e.printStackTrace();
}
}
On the Server side :
$json = $_POST['name1'];
$decoded = json_decode($json, TRUE);
and i got the undefined index notice.
Edit - revising my answer:
It appears you are sending a single parameter called json that contains 'name1' and 'name2' as the data.
Something like this should work: On the PHP side you need to decode the JSON first:
$json = json_decode($_POST['json']);
then you can access name1 and name2:
$name1 = $json['name1'];
$name2 = $json['name2'];
If you still get errors, I suggest printing out the $_POST and $_GET objects and see how your data is being sent. Then you will know how to access it.
Update:
the result you're getting array(0) { } means PHP did not get any parameters (GET or POST) from your request. You might try a different android example like this one:
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://example.com/JSON_FOLDER/JSON2/parseData.php");
post.setHeader("Content-type", "application/json");
post.setHeader("Accept", "application/json");
JSONObject json = new JSONObject();
json.put("name1", name1);
json.put("name2", name2);
post.setEntity(new StringEntity(json.toString(), "UTF-8"));
HttpResponse response = client.execute(post);
if( response != null ) {
str = inputStreamToString(response.getEntity().getContent()).toString();
Log.i("DATA", "Data send== " + str );
}
