i have issue with post request. Server gets me response message ok, but doesn't recognize json what i send as post body. I have tried almost everything. Php attribute $_POST is always empty.
Thank for your answers.
Json has structure :
{
"data": {
"email": "something#something.com",
"password": "tralala"
}
}
Android code :
public static Pair<Integer, String> signUpByEmailPost(String username, String passwd) {
try {
URL url = new URL(SERVER_URL + "create/createUser.php");
HttpURLConnection urlConn = (HttpURLConnection) url.openConnection();
urlConn.setRequestMethod("POST");
urlConn.setRequestProperty("Content-Type", "application/json");
urlConn.setDoOutput(true);
urlConn.setDoInput(true);
urlConn.setUseCaches(false);
urlConn.connect();
JSONObject json = createJsonCredentials(username, passwd);
String dataString = json.toString();
Log.i(TAG, dataString);
OutputStreamWriter out = new OutputStreamWriter(urlConn.getOutputStream());
out.write(dataString);
out.flush();
int httpResult = resolveHttpResponseCode(urlConn);
if(httpResult > 0) {
return new Pair<>(httpResult, null);
}
String receivedDataString = getStringContentFromConnection(urlConn);
return new Pair<>(0, receivedDataString);
} catch (Exception e) {
e.printStackTrace();
}
return new Pair<>(3, null);
}
private static JSONObject createJsonCredentials(String username, String password) {
try {
JSONObject jsonInner = new JSONObject();
jsonInner.put("email", "something#something.com");
jsonInner.put("password", "tralala");
JSONObject jsonOuter = new JSONObject();
jsonOuter.put("data", jsonInner);
return jsonOuter;
} catch(JSONException ex) {
ex.printStackTrace();
}
return null;
}
Server response :
{
success: false,
errors: {
email: "blank_email",
password: "blank_password"
}
}
Server side :
<?php
$data["post"] = $_POST;
$email = $_POST["data"]["email"];
$password = $_POST["data"]["password"];
if(empty($email)) {
$errors['email'] = 'blank_email';
}
if(empty($password)) {
$errors['password'] = 'blank_password';
}
echo json_encode($data);
?>
Hi here you are returning null value from your method. Try this code. It will work.
private static JSONObject createJsonCredentials(String username, String password) {
JSONObject jsonOuter = new JSONObject();
try {
JSONObject jsonInner = new JSONObject();
jsonInner.put("email", "something#something.com");
jsonInner.put("password", "tralala");
jsonOuter.put("data", jsonInner);
} catch(JSONException ex) {
ex.printStackTrace();
}
return jsonOuter;
}

bufferedReader.close();
return stringBuilder.toString();
}
finally{
urlConnection.disconnect();
}
}

return null;
}

response = "THERE WAS AN ERROR";
}
// progressBar.setVisibility(View.GONE);
Log.i("INFO", response);
// responseView.setText(response);

}
JSON parsing
private void jsonParsing(String response){
try {
JSONObject jObj = new JSONObject(response);
String result = jObj.getString("result");
if (result.equals("success")) {

}
} catch (JSONException e) {
// JSON error
e.printStackTrace();

And use this task as simple by using this

I am trying to get all the species result from the first url but sadly, my for loop can only retrieve one species from my first url and I don't know what's the correct logic here. Hope you can help me. I know the problem is my for loop but I don't know how to construct it correctly. Sorry. Newbie here.
search_species = txtSearchMap.getText().toString();
String url =
"http://192.168.1.9/android_login_api/search_species_map.php?species_name="
+ search_species;
pDialog.setMessage("Loading data...");
pDialog.show();
StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
#Override
public void onResponse(String s) {
try {
JSONObject jsonObject = new JSONObject(s);
JSONArray array = jsonObject.getJSONArray("tem");
for(int i = 0; i<array.length(); i++) {
JSONObject o = array.getJSONObject(i);
species_id = o.getString("localname");
common = o.getString("name");
scientific = o.getString("scientificname");
local = o.getString("localname");
ArrayList<HashMap<String, String>> location = null;
String url = "http://192.168.1.9/android_login_api/search_location_map.php?speciesid=" + species_id;
try {
JSONArray data = new JSONArray(getHttpGet(url));
location = new ArrayList<HashMap<String, String>>();
HashMap<String, String> map;
for(i = 0; i < data.length(); i++){
JSONObject c = data.getJSONObject(i);
map = new HashMap<String, String>();
map.put("locationid", c.getString("locationid"));
map.put("brgy", c.getString("brgy"));
map.put("town", c.getString("town"));
map.put("latitude", c.getString("latitude"));
map.put("longitude", c.getString("longitude"));
map.put("speciesid", local);
map.put("flowercolor", c.getString("flowercolor"));
location.add(map);
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_LONG).show();
}
This is my getHttpGet:
public static String getHttpGet(String url) {
StringBuilder str = new StringBuilder();
HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) { // Download OK
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new
InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
str.append(line);
}
} else {
Log.e("Log", "Failed to download result..");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return str.toString();
}
and this is the PHP file:
<?php
include 'dbconfig.php';
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$species_name = $_GET['species_name'];
$sql = "SELECT * from tbl_species WHERE CONCAT_WS(name, localname,
scientificname, familyname, flowercolor, leafshape) LIKE '%$species_name%'";
$result = $conn->query($sql);
if ($result->num_rows >0) {
$arr['aaData'] = array();
// output data of each row
while($row[] = $result->fetch_assoc()) {
$tem = $row;
$json = json_encode(array('tem' => $tem));
}
} else {
echo "0 results";
}
echo $json;
$conn->close();
?>
Specifically, my for loop can only get the first species, after getting that, the for loop stops to get the others. I don't know what's wrong and what I should change. I'm creating a project that can search a species by name, by color, by shape etc.
Just a guess but maybe because you use the same int in both for loops
for(int i = 0; i<array.length(); i++)
for(i = 0; i < data.length(); i++){
You have a NetworkOnMainThreadException and your app crashes when you handle the second url.
You could have told us of the crash.
You should execute all network/internet code in a thread or asynctask.
You must have 2 variables to save the values in PHP file.and use array_push for save all values in an array
search_species = txtSearchMap.getText().toString();
String url =
"http://192.168.1.9/android_login_api/search_species_map.php?type=first&species_name="
+ search_species;
.
.
.
local = o.getString("localname");
ArrayList<HashMap<String, String>> location = null;
String url = "http://192.168.1.9/android_login_api/search_location_map.php?type=tow&speciesid=" + species_id;
try {.....
and in PHP file
$type = $_GET['type'];
$response1 = array();
$response2 = array();
.
.
.
while($row[] = $result->fetch_assoc()) {
if (type ==="fist"){
array_push($response2,array('locationid' => $row['locationid'],'brgy'=>$row['brgy'],'town'=>$row['town'],'latitude'=>$row['latitude'],'flowercolor'=>$row['flowercolor']));
}elseif (type ==="tow"){
array_push($response2,array('locationid' => $row['locationid'],'brgy'=>$row['brgy'],'town'=>$row['town'],'latitude'=>$row['latitude'],'flowercolor'=>$row['flowercolor']));
}
}////end while
if (type ==="fist"){
echo $response1;
}elseif(type1 ==="tow"){
echo $response2;

I try to get information from this link
and I don't get it !
This is my code:
String s = getJSONFile();
String myDataArray[] = {};
try{
JSONObject reportJSON = new JSONObject();
JSONArray dateJSON = reportJSON.getJSONArray("terrestrial_date");
myDataArray = new String[dateJSON.length()];
for (int i = 0; i <dateJSON.length(); i++){
JSONObject jsonObject = dateJSON.getJSONObject(i);
myDataArray[i] = jsonObject.getString("terrestrial_date");
}
}catch (JSONException e){
e.printStackTrace();
}
ArrayAdapter<String> stringAdapter = new ArrayAdapter<String>(getApplicationContext(), R.layout.row, myDataArray);
if (mListView != null){
mListView.setAdapter(stringAdapter);
}
}
this is the getJSONFile method:
public String getJSONFile() {
String json = null;
try {
InputStream is = getResources().openRawResource(R.raw.weather_json);
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
return json;
}
Thanks for help :)
You should use GSON librari and for the Model of this code http://www.jsonschema2pojo.org/
This is so easy.
terrstial_date is a String of report. try this,
String date=jsonObject.getString("terestial_date");
also your json parsing structere is not correct accroding to your json
{
"report": {
"terrestrial_date": "2017-10-13",
"sol": 1844,
"ls": 73.0,
"min_temp": -81.0,
"min_temp_fahrenheit": -113.8,
"max_temp": -28.0,
"max_temp_fahrenheit": -18.4,
"pressure": 869.0,
"pressure_string": "Higher",
"abs_humidity": null,
"wind_speed": null,
"wind_direction": "--",
"atmo_opacity": "Sunny",
"season": "Month 3",
"sunrise": "2017-10-13T10:59:00Z",
"sunset": "2017-10-13T22:43:00Z"
}
}
This is how you can get response from OkHttp
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url("http://marsweather.ingenology.com/v1/latest/?format=json")
.get()
.build();
try {
Response response = client.newCall(request).execute();
String json = response.body().string();
JSONObject jsonObject = new JSONObject(json);
JSONObject reportJson = jsonObject.getJSONObject("report"); // your report object.
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
Put your Json file in your assets folder with .json extension and use this method to get JsonString from it
public String loadJSONFromAsset(String fileName) {
String json = null;
try {
InputStream is = getAssets().open(fileName);
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
json = new String(buffer, "UTF-8");
} catch (IOException ex) {
ex.printStackTrace();
return null;
}
return json;
}
And get the String using this function like this
String jsonString = MyApplication.loadJSONFromAsset(this,"yourJsonFileName.json");
and Parse like that
try{
JSONObject responce = new JSONObject(jsonString);
JSONArray report= responce.getJSONObject("report");
String terrestrial_date = report.getString("terrestrial_date");
}catch (JSONException e){
e.printStackTrace();
}
this is my code after all the change:
public void find_weather() {
String url = "http://marsweather.ingenology.com/v1/latest/?format=json";
JsonObjectRequest jor = new JsonObjectRequest(Request.Method.GET, url, null, new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONObject main_object = response.getJSONObject("results");
JSONArray array = response.getJSONArray("");
JSONObject object = array.getJSONObject(0);
String date = object.getString("date");
String tempMin = String.valueOf(main_object.getDouble("min_temp"));
String tempMax = String.valueOf(main_object.getDouble("max_temp"));
String atmo_opacity = object.getString("atmo_opacity");
mMaxTemp.setText("max_temp");
mMinTemp.setText("min_temp");
mAtmoOpacity.setText("atmo_opacity");
Calendar calendar = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("EEEE-MM-dd");
String formatted_data = sdf.format(calendar.getTime());
mDate.setText(formatted_data);
double temp_max_int = Double.parseDouble(tempMax);
double temp_min_int = Double.parseDouble(tempMin);
mMaxTemp.setText(String.valueOf(i));
mMinTemp.setText(String.valueOf(i));
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
});
RequestQueue queue = Volley.newRequestQueue(this);
queue.add(jor);
You are doing in wrong way
1.report is a JsonObject inside your response means you have your report inside another JsonObject. First you have to parse your response to get report data
2.terrestrial_date is a string data so you have to use report.getJsonString("terrestrial_date") you are using reportJSON.getJSONArray("terrestrial_date"); which is used for Array data
For, more information get a look here How to parse JSON in Android
Try this,
String s = getJSONFile();
String terrestrial_date = "";
try{
JSONObject responce = new JSONObject(s);
JSONObject report= responce.getJSONObject("report");
terrestrial_date = report.getString("terrestrial_date");
}catch (JSONException e){
e.printStackTrace();
}
EDIT
Try, Volley for fetching JSON data
First you need to add dependency of volley in build.gradle file-:
dependencies {
compile 'com.android.volley:volley:1.0.0'
}
Then use following code to fetch or parse your JSON data
// Tag used to cancel the request
String url = "http://marsweather.ingenology.com/v1/latest/?format=json";
StringRequest strReq = new StringRequest(Request.Method.GET,
url, new Response.Listener<String>() {
#Override
public void onResponse(String response) {
Log.d(TAG, response.toString());
String terrestrial_date = "";
try{
JSONObject responce = new JSONObject(response);
JSONObject report= responce.getJSONObject("report");
terrestrial_date = report.getString("terrestrial_date");
}catch (JSONException e){
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
Log.d(TAG, "Error: " + error.getMessage());
}
});
// Adding request to request queue
Volley.newRequestQueue(this).add(strReq);

you can use volley for handle http request
In android studio -put this line in your build.gradle
dependencies{
compile 'com.mcxiaoke.volley:library-aar:1.0.0'
}
Use this method (post) call this method
public void postData(){

new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {

sir this code perfectly show me all data from this server but i want some specific data like i want to show data related to the person who is logged in so for that i have to pass the user name to PHP script so dont have idea to POST any thing to web on the basis of which i can filter data
Here is an example:
JSONObject obj = new JSONObject();
obj.put("username", "YourUser");
HttpUrlConnectionJson.sendHTTPData("http://" + serverAddress + "/api/SomeUserMethod", obj);
HttpUrlConnectionJson class
public class HttpUrlConnectionJson {
private static final String TAG = "HttpUrlConnectionJson";
public static String sendHTTPData(String urlpath, JSONObject json) {
HttpURLConnection connection = null;
try {
URL url=new URL(urlpath);
connection = (HttpURLConnection) url.openConnection();
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Content-Type", "application/json");
connection.setRequestProperty("Accept", "application/json");
OutputStreamWriter streamWriter = new OutputStreamWriter(connection.getOutputStream());
streamWriter.write(json.toString());
streamWriter.flush();
StringBuilder stringBuilder = new StringBuilder();
if (connection.getResponseCode() == HttpURLConnection.HTTP_OK){
InputStreamReader streamReader = new InputStreamReader(connection.getInputStream());
BufferedReader bufferedReader = new BufferedReader(streamReader);
String response = null;
while ((response = bufferedReader.readLine()) != null) {
stringBuilder.append(response + "\n");
}
bufferedReader.close();
Log.d(TAG, stringBuilder.toString());
return stringBuilder.toString();
} else {
Log.e(TAG, connection.getResponseMessage());
return null;
}
} catch (Exception exception){
Log.e(TAG, exception.toString());
return null;
} finally {
if (connection != null){
connection.disconnect();
}
}
}
}
I hope this help
