Please help me. I did many and various way including changing flash firmware many versions but still it cannot request data from my website to display on Arduino LCD. I also try a few coding with wifiesp and without still it cannot read my Json file.
void loop() {
String payload = "";
bool parse_json = false;
char web_host[] = "putraelection.000webhostapp.com";
if (client.connect(web_host, 80)) {
Serial.println("CONNECT HOST");
String url = "/reqdatacalon.php";
client.print("GET " + url + "HTTP/1.0\r\n" +
"Host: " + web_host + "\r\n" +
//"Accept: application/json\r\n" +
//"Content-Type: text/html\r\n" +
"Connection: Keep-Alive\r\n" +
"\r\n");
while (client.connected() || client.available()) {
if (client.available()) {
//char c = client.read();
String b = client.readString();
Serial.println(b);
/*if (c == '{') {
parse_json = true;
}
if (parse_json) {
payload += c;
}*/
}
}
client.stop();
}
Serial.print("data");
Serial.println(payload);
payload.trim();
if (payload != "") {
DeserializationError error = deserializeJson(doc, payload);
if (error) {
Serial.println("ERROR JSON");
} else {
String can1 = doc["CANDIDATE 1"];
Serial.println ("calon 1:" +can1);
}
} else {
Serial.println("data kosong");
}
delay(5000);
}
I have a JSON looking like this:
{
"foo": {
"bar": {
"type": "someType",
"id": "ga241ghs"
},
"tags": [
{
"#tagId": "123",
"tagAttributes": {
"attr1": "AAA",
"attr2": "111"
}
},
{
"#tagId": "456",
"tagAttributes": {
"attr1": "BBB",
"attr2": "222"
}
}
]
},
"text": "My text"
}
Actually it's not split to multiple lines (just did it to give a better overview), so it's looking like this:
{"foo":{"bar":{"type":"someType","id":"ga241ghs"},"tags":[{"#tagId":"123","tagAttributes":{"attr1":404,"attr2":416}},{"#tagId":"456","tagAttributes":{"attr1":1096,"attr2":1103}}]},"text":"My text"}
I want to insert this JSON with Logstash to an Elasticsearch index. However, I want to insert a flattened JSON with the fields in the array combined like this:
"foo.bar.tags.tagId": ["123", "456"]
"foo.tags.tagAttributs.attr1": ["AAA", "BBB"]
"foo.tags.tagAttributs.attr2": ["111", "222"]
In total, the data inserted to Elasticsearch should look like this:
"foo.bar.type": "someType"
"foo.bar.id": "ga241ghs"
"foo.tags.tagId": ["123", "456"]
"foo.tags.tagAttributs.attr1": ["AAA", "BBB"]
"foo.tags.tagAttributs.attr2": ["111", "222"]
"foo.text": "My text"
This is my current Logstash .conf; I am able to split the "tags" array, but now I am getting 2 entries as a result.
How can I now join all tagIds to one field, attr1 values of the array to one field, and all attr2 values to another?
input {
file {
codec => json
path => ["/path/to/my/data/*.json"]
mode => "read"
file_completed_action => "log"
file_completed_log_path => ["/path/to/my/logfile"]
sincedb_path => "/dev/null"
}
}
filter {
split {
field => "[foo][tags]"
}
}
output {
stdout { codec => rubydebug }
}
Thanks a lot!
Nice example for my JSON iterator IIFE - no need for complex algos, just pick DepthFirst, sligthly modified path (new "raw" version) and that is it.
In case you like this JS answer, mind ticking accept flag under voting buttons.
In case you want different language, have also C# parser with similar iterators on same GitHub.
var src = {"foo":{"bar":{"type":"someType","id":"ga241ghs"},"tags":[{"#tagId":"123","tagAttributes":{"attr1":"AAA","attr2":"111"}},{"#tagId":"456","tagAttributes":{"attr1":"BBB","attr2":"222"}}],"text":"My text"}};
//console.log(JSON.stringify(src, null, 2));
function traverse(it) {
var dest = {};
var i=0;
do {
if (it.Current().HasStringValue()) {
var pathKey = it.Path(true).join('.');
var check = dest[pathKey];
if (check) {
if (!(check instanceof Array)) dest[pathKey] = [check];
dest[pathKey].push(it.Value());
} else {
dest[pathKey] = it.Value();
}
}
//console.log(it.Level + '\t' + it.Path(1).join('.') + '\t' + it.KeyDots(), (it.Value() instanceof Object) ? "-" : it.Value());
} while (it.DepthFirst());
console.log(JSON.stringify(dest, null, 2));
return dest;
}

Your short JSON version was different, now using this one, which looks like your required results (attrs changed and text moved from root under foo):
{
"foo": {
"bar": {
"type": "someType",
"id": "ga241ghs"
},
"tags": [
{
"#tagId": "123",
"tagAttributes": {
"attr1": "AAA",
"attr2": "111"
}
},
{
"#tagId": "456",
"tagAttributes": {
"attr1": "BBB",
"attr2": "222"
}
}
],
"text": "My text"
}
}
Figured it out how to do it with a Ruby filter directly in Logstash - for all searching for this in future, here is one example on how to do it for #tagId:
filter {
ruby { code => '
i = 0
tagId_array = Array.new
while i < event.get( "[foo][tags]" ).length do
tagId_array = tagId_array.push(event.get( "[foo][tags][" + i.to_s + "][#tagId]" ))
i += 1
end
event.set( "foo.tags.tagId", tagId_array )
'
}
}
We need to print Arabic text using Bluetooth Printer in windows phone 8 silver light app. Printing is working fine for English When we are trying to print Arabic text it is not printing as expected? Sample code is given Below:
Public async void PrintTest(string text)

if (isConnected)
{
try
{
if (_socket != null)
{
DataWriter writer = new DataWriter(_socket.OutputStream);
writer.WriteString(text);
writer.WriteBytes(Cmd_ESC_JN); // byte[] Cmd_ESC_JN = new byte[] { 27, 74, 230 };
writer.StoreAsync();
}
}
catch { }
}
}
public async Task<bool> RefreshPairedDevicesList()
{
try
{
PeerFinder.AlternateIdentities["Bluetooth:Paired"] = "";
var peers = await PeerFinder.FindAllPeersAsync();
if (peers == null && peers.Count == 0)

How to dynamically (in code behind) select few items in Windows Phone Toolkit's LongListMultiSelector. The property SelectedItems has no setter.
My code:
private async void GetGenres()
{
var genres = await App.MusClient.GetGenresAsync();
var preferencedGenresIdsList = App.GetFromIsoStorage<List<string>>(App.GENRES_IDS_KEY_STRING);
GenresListBox.ItemsSource = genres;
foreach (var item in GenresListBox.ItemsSource)
{
if (preferencedGenresIdsList.Contains(((Genre)item).Id))
{
LongListMultiSelectorItem container = GenresListBox.ContainerFromItem(item) as LongListMultiSelectorItem;
if (container != null)
{
container.IsSelected = true;
}
}
}
if (genres.Result == null || genres.Count == 0)
{
MessageBox.Show("No results available");
}
}
I found solution
private async void GetGenres()
{
var genres = await App.MusClient.GetGenresAsync();
var preferencedGenresIdsList = App.GetFromIsoStorage<List<string>>(App.GENRES_IDS_KEY_STRING);
GenresListBox.ItemsSource = genres;
foreach (var item in GenresListBox.ItemsSource)
{
if (preferencedGenresIdsList.Contains(((Genre)item).Id))
{
GenresListBox.ScrollTo(item);
LongListMultiSelectorItem container = GenresListBox.ContainerFromItem(item) as LongListMultiSelectorItem;
if (container != null)
{
container.IsSelected = true;
}
}
}
GenresListBox.ScrollTo(GenresListBox.ItemsSource[0]);
if (genres.Result == null || genres.Count == 0)
{
MessageBox.Show("No results available");
}
}
Reason it didn't work is because item is not created on UI yet.
GenresListBox.ScrollTo(item); - forces UI to create element!
I'm new to Windows phone 8 development. I'm trying to navigate from my AzureFunctions class to another page but I always get this error
Object reference not set to an instance of an object.
I have googled but still can't find any solution. Do you guys have any idea how to achieve this?
My RegisterPage (where I called InsertData method in AzureFunctions class)
private void signUp_button_Click(object sender, RoutedEventArgs e)
{
if (email_validation && password_validation && confirmPassword_validation == true)
{
new AzureFunctions().InsertData(new UserInfo_Table_Azure()
{
Email = regisEmail_textBox.Text,
Password = regisPassword_textBox.Password,
DOB = (DateTime)DOB_picker.Value,
UserCancerInfo = (Boolean)userCancerInfo_checkBox.IsChecked,
FamilyCancerInfo = (Boolean)userFamilyCancerInfo_checkBox.IsChecked
});
}
else
{
String errorMsg = "";
if (email_validation == false)
{
errorMsg += "Your email is not valid\r\n";
regisEmail_textBox.BorderBrush = new SolidColorBrush(Colors.Red);
}
if (password_validation == false)
{
errorMsg += "Your password can't be empty\r\n";
regisPassword_textBox.BorderBrush = new SolidColorBrush(Colors.Red);
}
if (confirmPassword_validation == false)
{
errorMsg += "Your Confirm password and password aren't matched";
comfirmPassword_textBox.BorderBrush = new SolidColorBrush(Colors.Red);
}
MessageBox.Show(errorMsg);
}
}
My AzureFunctions Class
public async void InsertData(object data)
{
try
{
SystemFunctions.SetProgressIndicatorProperties(true);
SystemTray.ProgressIndicator.Text = "Registering...";
//Check type of data
if (IsUserInfo_Data(data))
{
//Insert data into UserInfo_Table
await azure_userInfo_table.InsertAsync((UserInfo_Table_Azure)data);
Debug.WriteLine("Success inserting data to azure");
SystemFunctions.SetProgressIndicatorProperties(false);
MessageBoxResult result = MessageBox.Show(AppResources.RegisterSuccessfully, AppResources.Congratulation, MessageBoxButton.OK);
if (result == MessageBoxResult.OK)
{
try
{
new RegisterPage().NavigationService.Navigate(new Uri("/MainPage.xaml", UriKind.Relative));
}
catch (NullReferenceException e)
{
Debug.WriteLine(e.Message);
}
}
}
else if (IsPoop_Data(data))
{
//Insert data into Poop_Table
await azure_poop_table.InsertAsync((Poop_Table_Azure)data);
Debug.WriteLine("Success");
}
}
catch (MobileServiceInvalidOperationException e)
{
SystemFunctions.SetProgressIndicatorProperties(false);
Debug.WriteLine("Failed: " + e.Message);
}
}
Not really a good idea to do navigation from a non-Page, but this should work
App.RootFrame.Navigate(...)
