I have some JSONP in my application, & I want to set timeout for them. How can I set it?
it maybe something like this, if it is possible :)
Ext.util.JSONP.request({
url: mhid.dashboard.hbf.controller+'/get_dashboard'
,method: 'POST'
,timeout : 50000 // TIMEOUT
,callbackKey: 'jsonp_callback'
,params:{
'site' : site
,'fleet' : fleet
,'sn' : sn
,'format' : 'json'
}
,callback: function(response, opts) {
var obj = response;
tpl.overwrite('content', obj);
loadMask.hide();
}
,failure: function(response, opts) {
alert('Failure');
}
});
Thanks in advance
I don't think it is possible using JSONP - you should take a look at the Ext.Ajax class. Also, POST is not possible using JSONP (refer to the Sencha forum
You will need to implement your own timeout and execute the failure callback:
var failureCallback = function() {
// MUST remove the current request,
// or it will not dispatch any subsequent new JSONP request
// unless you refresh your page
delete Ext.util.JSONP.current;
alert('Failure');
};
Ext.util.JSONP.request({..}); // as usual
var failureTimeoutId = setTimeout(function() {
failureCallback();
}, 30000);
discard the timeout if your request is success
discard current request if the request has timed out

I'm using Http from #angular/http to send GET requests, but the server is not receiving the request. The generated urls are correct because when I log them and open them in browser (I've tried all of Chrome, Firefox and Safari), the server does receive these requests.
This is how I am doing this:
let logButtonUrl = this.urlGenerator.generateTiramisuUrlTemp(this.servletPath,
argMap);
console.log("logButtonUrl:"+logButtonUrl);
return this.http.get(logButtonUrl).map(this.writeSuccess);
Function writeSuccess:
private writeSuccess(res: Response) {
let body = res.json();
let rows_affected = body.data[0].rowsAffected;
if (rows_affected == "1") {
return true;
} else {
return false;
}
}
I got no error message in browser console, so it's probably not because of the CORS issue discussed here:
http://blog.ionic.io/handling-cors-issues-in-ionic/
I also tried using a proxy. I added this in ionic.config.json:
{
"path": "/backendTemp",
proxyUrl": "http://128.237.217.70:8080" /*the ip address of the target server*/
}
And replace the ip address in my generated urls with "/backendTemp". Still not working.
Any suggestions/thoughts on this? Thanks a lot!
Use the $http (https://docs.angularjs.org/api/ng/service/$http):
.controller('RequestCtrl', function ($http) {
$http({
method: 'GET',
url: 'http://128.237.217.70:8080/backendTemp'
}).then(function successCallback(response) {
// this callback will be called asynchronously
// when the response is available
}, function errorCallback(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
I'm parsing remote data in to my app and uses it through arguments. One of the data types is a url adresse i want to open in the url. I have an idea that I have to open it with the openURL function but I can't seem to get it to work. Anyone have a working example?
You have to utilize in-built HttpClient
var url = "http://www.you_remote_url.com";
var client = Ti.Network.createHTTPClient({
// function called when the response data is available
onload : function(e) {
Ti.API.info("Received text: " + this.responseText);
alert('success');
},
// function called when an error occurs, including a timeout
onerror : function(e) {
Ti.API.debug(e.error);
alert('error');
},
timeout : 5000 // in milliseconds
});
// Prepare the connection.
client.open("GET", url);
// Send the request.
client.send();
My question is very similar to this one which describes how to serve a local file using Iron Router. I need to do the same, but instead of reading the file synchronously from disk, I need to get the file from S3 which is an asynchronous call.
The problem appears to be the fact that the action method has returned before the asynchronous s3.getObject completes giving me the following error.
Error: Can't render headers after they are sent to the client.
I'm assuming that Iron Router is generating the response for me when it realizes that I haven't handled the response in my action method, but I'm stumped about how to tell it to wait for my asynchronous call to finish.
Here is my code.
Router.map(function () {
this.route('resumeDownload', {
where: 'server',
path: '/resume/:_id',
action: function () {
var response = this.response;
var candidate = Candidates.findOne(this.params._id);
if (!candidate || !candidate.resumeS3Key) {
// this works fine because the method hasn't returned yet.
response.writeHead(404);
return response.end();
}
var s3 = new AWS.S3();
s3.getObject({Bucket: 'myBucket', Key: candidate.resumeS3Key}, function (err, data) {
if (err) {
// this will cause the error to be displayed
response.writeHead(500);
return response.end();
}
// this will also cause the error to be displayed
response.writeHead(200, {'Content-Type': data.ContentType});
response.end(data.Body);
});
}
});
});
I was able to solve this one myself. I needed to use a future in my action method.
Here is the working code.
Router.map(function () {
this.route('resumeDownload', {
where: 'server',
path: '/resume/:_id',
action: function () {
var response = this.response,
candidate = Candidates.findOne(this.params._id);
if (!candidate || !candidate.resumeS3Key) {
response.writeHead(404);
return response.end();
}
var Future = Npm.require('fibers/future'),
s3 = new AWS.S3(),
futureGetObject = Future.wrap(s3.getObject.bind(s3)),
data = futureGetObject({Bucket: 'myBucket', Key: candidate.resumeS3Key}).wait();
response.writeHead(200, {'Content-Type': data.ContentType});
response.end(data.Body);
}
});
});
I have this very simple code to read the response from a server endpoint after a post request. Actually I'm saving a data to a database and wait for a response before going to next step
casper.open('http://example.com/ajax.php, {
method: 'POST',
data: {
'title': '<title>',
'unique_id': '<unique_id>'
}
});
on ajax.php file I'm trying to echo the POST request in a simple way.
this will let me know easily if I'm getting the right response from the server.
echo json_encode($_POST);
I tried these snippets but I'm unable to get the response.
casper.on('page.resource.received', function(resp){
this.echo(JSON.stringify(resp, null, 4));
});
casper.on('http.status.200', function(resp){
this.echo(JSON.stringify(resp, null, 4));
});
casper.on('resource.received', function(resp) {
this.echo(JSON.stringify(resp, null, 4));
});
I've been facing the same problem POSTing a query to ElasticSearch and I could not retrieve the results.
As far as I can understand if you want to retrieve the data echoed by your script the solution could be this:
this.echo(this.page.content);
or
this.echo(this.page.plainText);
in your function.
For example (my case with ElasticSearch):
/*
* SOME VAR DEFINITIONS HERE
*/
casper.start();
casper.then( function() {
// the next var is very specific to ElasticSearch
var elasticQuery = JSON.stringify (
{
'size' : 20,
'query' : {
'filtered' : {
'filter' : { 'term' : { 'locked' : false } }
}
},
'sort': { 'lastScrapeTime': { 'order': 'asc' } }
}
);
var elasticRequest = {
method: 'POST',
data: elasticQuery
}
this.thenOpen( <<YOUR URL>>, elasticRequest, function (response) {
// dump response header
require('utils').dump(response);
// echo response body
this.echo(this.page.content);
// echo response body with no tags added (useful for JSON)
this.echo(this.page.plainText);
});
}
);
casper.run();
As Roberto points out. You can use this.page.content to show the response. But you need to add the function(response) in your script. For example:
casper.open('http://example.com/ajax.php', {
method: 'POST',
data: {
'title': '<title>',
'unique_id': '<unique_id>'
}
}, function(response){
if(response.status == 200){
require('utils').dump(this.page.content);
}
});
If you want to unit test a REST API, CasperJS is not necessarily the right tool.
CasperJS allows to observe a web browser which is running a web page.
So a more typical approach would be to use CasperJS to load a page that would call your REST API and you would assert the page behavior is correct (assuming the page would make something observable according the AJAX call response).
Does anyone have an example of an API response being passed back from a http.request() made to a 3rd party back to my clientSever and written out to a clients browser?
I keep getting stuck in what I'm sure is simple logic. I'm using express from reading the docs it doesn't seem to supply an abstraction for this.
Thanks
Note that the answer here is a little out of date-- You'll get a deprecated warning. The 2013 equivalent might be:
app.get('/log/goal', function(req, res){
var options = {
host : 'www.example.com',
path : '/api/action/param1/value1/param2/value2',
port : 80,
method : 'GET'
}
var request = http.request(options, function(response){
var body = ""
response.on('data', function(data) {
body += data;
});
response.on('end', function() {
res.send(JSON.parse(body));
});
});
request.on('error', function(e) {
console.log('Problem with request: ' + e.message);
});
request.end();
});
I would also recommend the request module if you're going to be writing a lot of these. It'll save you a lot of keystrokes in the long run!
Here is a quick example of accessing an external API in an express get function:
app.get('/log/goal', function(req, res){
//Setup your client
var client = http.createClient(80, 'http://[put the base url to the api here]');
//Setup the request by passing the parameters in the URL (REST API)
var request = client.request('GET', '/api/action/param1/value1/param2/value2', {"host":"[put base url here again]"});
request.addListener("response", function(response) { //Add listener to watch for the response
var body = "";
response.addListener("data", function(data) { //Add listener for the actual data
body += data; //Append all data coming from api to the body variable
});
response.addListener("end", function() { //When the response ends, do what you will with the data
var response = JSON.parse(body); //In this example, I am parsing a JSON response
});
});
request.end();
res.send(response); //Print the response to the screen
});
Hope that helps!
This example looks pretty similar to what you are trying to achieve (pure Node.js, no express):
