Does someone know how to get weather information in Titanium? I read that the Google Weather API is no longer available. I have tried this link but I can't figure out how to put this to work.
Does someone have a working code? I would like to get the weather on my position given by longitude and latitude.
Titanium.Geolocation.getCurrentPosition(function(e) {
if (e.error) {
return;
} else {
var lon = e.coords.longitude;
var lat = e.coords.latitude;
if (Ti.Network.networkType == Ti.Network.NETWORK_NONE) {
return;
} else {
var client = Ti.Network.createHTTPClient({
onload : function(e) {
var weather = JSON.parse(this.responseText);
getweatherIcon(weather.weather[0].icon);
setweatherText(weather.weather[0].id, weather.main.temp);
},
onerror : function(e) {
},
timeout : 150000
});
client.open("GET", "http://api.openweathermap.org/data/2.5/weather?lat=" + latitude + "&lon=" + longitude + "&appid=CreatedAppID");
client.send();
}
}
});
The "CreatedAppID" is the ID that I have created after creating an account on the provided link that is above.

I'm trying to add a backup route for a tiles with ol3. I would like to test on the errorload event if the source url starting by "http".
If "yes" : replace this tile by a custom tile.
If "no" : change the source url of this tile by another one and retry
I think i need to use something like that :
layerTile.getSource().setUrl('file:///local/{z}/{x}/{y}.jpg');
var errorTilePath='https://image.noelshack.com/fichiers/2017/14/1491403614-errortile.png';
var serverBackup='http://otile1.mqcdn.com/tiles/1.0.0/map/';
layerTile.getSource().setTileLoadFunction((function() {
var tileLoadFn = layerTile.getSource().getTileLoadFunction();
return function(tile, src) {
var image = tile.getImage();
image.onload = function() {console.log('Tile ok : ' + src); };
image.onerror = function() {
console.log('Tile error : ' + src);
console.log(tile);
if (src.substr(0,4)!='http') {
var tmp=src.split('/').reverse();
var serverBackupPath=serverBackup+tmp[2]+'/'+tmp[1]+'/'+tmp[0].split('.')[0]+'.png';
console.log("Second url : " + serverBackupPath)
src=serverBackupPath;
tile.getImage().src=src;
var image = tile.getImage();
image.onload = function() {console.log('Tile backup ok : ' + src);};
image.onerror = function() {console.log('Tile backup error : ' + src); src=errorTilePath; tile.getImage().src=src; tileLoadFn(tile, src);}
} else {
console.log('Custom tile : ');
src=errorTilePath;
tile.getImage().src=src;
}
tileLoadFn(tile, src);
};
tileLoadFn(tile, src);
};
})());
With that, I can see that the backup tile is downloaded but not visible on map.
Certainely, I misunderstood something.
Thanks in advance if somebody could help me.
Oups, without code my answer is null.
layerTile.getSource().setUrl('file:///local/{z}/{x}/{y}.jpg');
var serverBackup='https://{a-c}.tile.openstreetmap.org/';
var errorTilePath=urlBase+'css/images/error.png';
layerTile.getSource().setTileLoadFunction((function() {
return function(tile, src) {
if (UrlExists(src)) {
tile.getImage().src=src;
} else {
if (src.substr(0,4)=='file') {
var tmp=src.split('/').reverse();
src='https://'+['a', 'b', 'c'].sort(function() {return 0.5 - Math.random()})[0]+'.tile.openstreetmap.org/'+tmp[2]+'/'+tmp[1]+'/'+tmp[0].split('.')[0]+'.png';
if (UrlExists(src)) {
tile.getImage().src=src;
} else {
tile.getImage().src=errorTilePath;
}
} else {
tile.getImage().src=errorTilePath;
}
}
};
})());
function UrlExists(url){
try {
var http = new XMLHttpRequest();
http.open('HEAD', url, false);
http.send();
return http.status==200||http.status==403;
} catch(err){return false;}
}
I am trying to teach myself nodejs and expressjs, however coming from java and c++ this is proving difficult to get used to.
I made a simple and messy module that it is supposed to return a weather forecast for a given zip code.
The way this happens is by taking the user zip code and using a google api to generate the geo coordinates for that zip code. I get the coordinates from the JASON file and then provide them to the next api call, this call is done to the forecast.io api and this time the weather data for the location is also taken from a JASON file.
Coming from java and with a not so solid background on JavaScript I am having a hard time making these two functions wait for one another, in this case I need the google api call to finish first because the coordinates it will provide are needed for the second api call. Can someone take a look at this code and tell me if the strategy I used is correct/ provide a suggestion so that I can know what is done in javascript in situations like this.
here is the code:
// The required modules.
var http = require("http");
var https = require("https");
//result object
var resultSet = {
latitude :"",
longitude:"",
localInfo:"",
weather:"",
humidity:"",
pressure:"",
time:""
};
//print out error messages
function printError(error){
console.error(error.message);
}
//Forecast API required information:
//key for the forecast IO app
var forecast_IO_Key = "this is my key, not publishing for security reasons";
var forecast_IO_Web_Adress = "https://api.forecast.io/forecast/";
//Create Forecast request string function
function createForecastRequest(latitude, longitude){
var request = forecast_IO_Web_Adress + forecast_IO_Key + "/"
+ latitude +"," + longitude;
return request;
}
//Google GEO API required information:
//Create Google Geo Request
var google_GEO_Web_Adress = "https://maps.googleapis.com/maps/api/geocode/json?address=";
function createGoogleGeoMapRequest(zipCode){
var request = google_GEO_Web_Adress+zipCode + "&sensor=false";
return request;
}
function get(zipCode){
// 1- Need to request google for geo locations using a given zip
var googleRequest = https.get(createGoogleGeoMapRequest(zipCode), function(response){
//console.log(createGoogleGeoMapRequest(zipCode));
var body = "";
var status = response.statusCode;
//a- Read the data.
response.on("data", function(chunk){
body+=chunk;
});
//b- Parse the data.
response.on("end", function(){
if(status === 200){
try{
var coordinates = JSON.parse(body);
resultSet.latitude = coordinates.results[0].geometry.location.lat;
resultSet.longitude = coordinates.results[0].geometry.location.lng;
resultSet.localInfo = coordinates.results[0].address_components[0].long_name + ", " +
coordinates.results[0].address_components[1].long_name + ", " +
coordinates.results[0].address_components[2].long_name + ", " +
coordinates.results[0].address_components[3].long_name + ". ";
}catch(error){
printError(error.message);
}finally{
connectToForecastIO(resultSet.latitude,resultSet.longitude);
}
}else{
printError({message: "Error with GEO API"+http.STATUS_CODES[response.statusCode]})
}
});
});
function connectToForecastIO(latitude,longitude){
var forecastRequest = https.get(createForecastRequest(latitude,longitude),function(response){
// console.log(createForecastRequest(latitude,longitude));
var body = "";
var status = response.statusCode;
//read the data
response.on("data", function(chunk){
body+=chunk;
});
//parse the data
response.on("end", function(){
try{
var weatherReport = JSON.parse(body);
resultSet.weather = weatherReport.currently.summary;
resultSet.humidity = weatherReport.currently.humidity;
resultSet.temperature = weatherReport.currently.temperature;
resultSet.pressure = weatherReport.currently.pressure;
resultSet.time = weatherReport.currently.time;
}catch(error){
printError(error.message);
}finally{
return resultSet;
}
});
});
}
}
//define the name of the outer module.
module.exports.get = get;
is the return statement properly placed? Is my use of finally proper in here? Please notice that I come from a java background and in java is perfectly fine to use the try{} catch(){} and finally{} blocks to execute closure code, it was the only way i managed this module to work. But now that i have incorporated some Express and I try to execute this module's method from another module, all I am getting is an undefined return.
You could use the Promise API, kind of like Futures in Java, so basically what you could do is wrap both functions in promises and the you could wait for resolve to execute the next function
var googleRequest = function(zipcode) {
return new Promise(function(resolve, reject) {
var request = https.get(createGoogleGeoMapRequest(zipCode), function(response) {
if (response.statusCode !== 200) {
reject(new Error('Failed to get request status:' + response.statusCode));
}
var body = "";
//a- Read the data.
response.on("data", function(chunk) {
body+=chunk;
});
//b- Parse the data.
response.on("end", function(body) {
var coordinates = JSON.parse(body);
resultSet.latitude = coordinates.results[0].geometry.location.lat;
resultSet.longitude = coordinates.results[0].geometry.location.lng;
resultSet.localInfo = coordinates.results[0].address_components[0].long_name + ", " +
coordinates.results[0].address_components[1].long_name + ", " +
coordinates.results[0].address_components[2].long_name + ", " +
coordinates.results[0].address_components[3].long_name + ". ";
resolve(resultSet);
})
});
request.on('error', function(err) {
reject(err);
});
});
}
After that you could just do
googleRequest(90210).then(function(result) {
connectToForecastIO(result.latitude, result.longitude);
}
You can find out more about Promise's usage in the Promise API docs
You should also note that there are several libraries available that allow for promise based http requests such as fetch
I'm developing an App that gets data from ACS, the post objects.
In my app there is button and when the users click that button it get the posts data.
In every post there is also a photo_id, which allows me to get the photo url from the cloud.
But there is a problem, it has a callback function and by the time the callback occurs it is too late.
Anyway, the code below only shows the last post with a photo, the first post doesn't have a photo.
(there are only 2 post objects so far).
I believe the problem is in the callback, but I can't seem to fix it.
Hope you guys can help me out, thanks in advance!
Here is my code:
function getCarsClick() {
Cloud.Posts.query({
page: 1,
per_page: 20
}, function (e) {
if (e.success) {
var tableData = [];
for (var i = 0; i < e.posts.length; i++) {
var post = e.posts[i];
var row = Titanium.UI.createTableViewRow();
var title = Titanium.UI.createLabel({
text:post.title,
font:{fontSize:18,fontWeight:'bold'},
color:'#ef349d',
width:'auto',
textAlign:'left',
top:2,
left:40,
height:30
});
var subtitle = Titanium.UI.createLabel({
text:post.content,
font:{fontSize:12,fontWeight:'normal'},
color:'#000000',
width:'auto',
textAlign:'left',
bottom:10,
left:60,
height:32
});
row.add(title);
row.add(subtitle);
row.hasChild=true;
row.height = 80;
row.selectedBackgroundColor = '#ef349d';
Cloud.Photos.show({
photo_id: post.photo_id
}, function (e) {
if (e.success) {
var photo = e.photos[0];
var img1 = Ti.UI.createImageView({image:photo.urls.square_75,width:30,height:30,left:2, top:2});
row.add(img1);
} else {
alert('Error:\n' +
((e.error && e.message) || JSON.stringify(e)));
}
});
tableData.push(row);
}
//add table data
$.tableview1.setData(tableData);
} else {
alert('Error:\n' +
((e.error && e.message) || JSON.stringify(e)));
}
});
}
If you pass a photo into the post using the default parameter provided, the image should come back by default and not require you to make an additonal API call to get the photo.
I would also suggest if you are just starting out to use Alloy and more importantly use ListViews not TableView

We have observed that at certain times accessing the JSONStore API's hangs for long time, to make it work we have to call the function again or app has to be taken to background & bring to foreground again.
NOTE : when application faces this issue, behaviour is same until we reinstall the app or reboot the device.
There doesn't appear to be any proper scenarios for this, we have searched many articles but did not find any solution, any solutions are welcome.
We observed this issue on Android devices like S5 and S4.
Here is my code Snippet:
function getWidgets(w_id, getWidgetsSuccessCallback, getWidgetsFailureCallback) {
var query = { user_id : w_id };
var options = {};
WL.JSONStore.get(StorageCollections.widgets).find(query, options)
.then(function(arrayResults) {
var count = arrayResults.length;
Logger.debug("getWidgets: success, count: " + count);
...
getWidgetsSuccessCallback(widgets);
})
.fail(function(errorObject) {
Logger.error("getWidgets: failed, error: " + JSON.stringify(errorObject));
getWidgetsFailureCallback(errorObject);
});}
Logs when everything works fine http://pastebin.com/NVP8ycTG
Logs when accessing JSON store hangs, it will work only when app taken to background & bring back to foreground again http://pastebin.com/eYzx57qC
JSON store is initialised as below
var collections = {
// User
user: {
searchFields: {
user_id : 'string',
user_name : 'string',
first_name : 'string',
last_name : 'string',
}
}
}};
// Storage encryption
var options = {};
if (key) {
options.password = key;
options.localKeyGen = true;
}
// Open the collection
var promise = WL.JSONStore.init(collections, options)
.then(function() {
Logger.debug("initializeAppStorage: " + JSON.stringify(collections) + " completed");
initAppStorageSuccessCallback(true);
return true;
})
// Handle failure
.fail(function(errorObject) {
Logger.error("initializeAppStorage: failed, error: " + errorObject.toString());
initAppStorageFailureCallback(errorObject.toString());
return false;
});
return promise;
Thanks.
Try this one :
function getWidgets(w_id, getWidgetsSuccessCallback, getWidgetsFailureCallback) {
var query = { key : w_id };
var options = {};
WL.JSONStore.get(StorageCollections.widgets).find(query, options)
.then(function(arrayResults) {
var count = arrayResults.length;
Logger.debug("getWidgets: success, count: " + count);
...
getWidgetsSuccessCallback(widgets);
})
.fail(function(errorObject) {
Logger.error("getWidgets: failed, error: " + JSON.stringify(errorObject));
getWidgetsFailureCallback(errorObject);
});}
Ti.GeoLocation.forwardGeocoder() is not converting Non US address to lat and long values.
sample code below.
Ti.GeoLocation.forwardGeocoder('Hyderabad, India', function(e){
var lat = e.latitude;
var long = e.longitude;
});
with this code we are getting lat and long values are undefined.
The proper way to get US addresses, and everywhere else in the world (that Google can find) and display the Long/Lat on a titanium Map.
The code below uses the string variable: myAddress
var myAddress = address + ','+ city + ',' + postal + ',' + country //'Vieux Port, Montreal, Quebec, H2X3R4, Canada'
var xhrGeocode = Ti.Network.createHTTPClient();
xhrGeocode.setTimeout(120000);
xhrGeocode.onerror = function (e) {
alert('Google couldn\'t find the address... check your address');
};
xhrGeocode.onload = function (e) {
var response = JSON.parse(this.responseText);
if (response.status == 'OK' && response.results != undefined && response.results.length > 0) {
longitude = response.results[0].geometry.location.lng;
latitude = response.results[0].geometry.location.lat;
}
};
var urlMapRequest = "http://maps.google.com/maps/api/geocode/json?address=" + myAddress.replace(/ /g, '+');
urlMapRequest += "&sensor=" + (Ti.Geolocation.locationServicesEnabled == true);
xhrGeocode.open("GET", urlMapRequest);
xhrGeocode.setRequestHeader('Content-Type', 'application/json; charset=utf-8');
xhrGeocode.send();
var addrReq = Titanium.Network.createHTTPClient();
var addrUrl = "http://maps.googleapis.com/maps/api/geocode/json?sensor=true&address="+ query;
addrReq.open("GET",addrUrl);
addrReq.send(null);
addrReq.onload = function()
{
var response = JSON.parse(this.responseText);
if(response.status == "OK"){
LT.Customlat=response.results[0].geometry.location.lat;
LT.Customlon=response.results[0].geometry.location.lng;
}
you will need to roll your own solution using google REST APIs, the underlying Titanium API does not support non-us addresses
