Parsing JSON from server using EXTjs4 - extjs4

i am getting problem in parsing JSON which starts as [{....}] this while i am able to parse JSON of format {"Ex"[{........}] }
and please resolve my problem
Ext.data.JsonP.request({
type:'jsonp',
url: ' x/y/z ',
method:'POST',
callbackkey:'callback',
params:{
format:'json'
},
callback:function (response, value, request) {
var localdata = JSON.stringify(value);
localStorage.setItem('ProjectDetailsJS', localdata);
var retrievedObject = localStorage.getItem('ProjectDetails');
console.log("List are"+localdata);
alert('Success')
},
failure:function (response, request) {
alert('failure')
},
error:function(){
alert('error')
}
});

Would suggest you read the documentation about JSONP. It requires the resulting data to be wrapped in a function. There are examples here: http://docs.sencha.com/ext-js/4-0/#!/api/Ext.data.proxy.JsonP

Rally API create ConversationPost

with the following code I'm trying to create new conversation post for Capability. But it says
Cannot parse input stream due to I/O error as JSON document: Parse error: expected '{' but saw '￿' [ chars read = >>>￿<<< ]
function createPost(objId, post) {
objId = "313878829904";
post = "<p>MindMap:Hello from GAS.</p>"
var url = "https://rally1.rallydev.com/slm/webservice/v2.0/conversationpost/create";
var payload = {
"ConversationPost": {
"Artifact": "/portfolioitem/capability/" + objId,
"Text": post
}
}
var method = "POST";
var options = optionsPost_(method, payload);
var response = UrlFetchApp.fetch(url, optionsPost_(method, options));
var content = JSON.parse(response.getContentText());
content.CreateResult.Errors.forEach(error => Logger.log(error));
}
function optionsPost_(method, payload) {
var rallyApiKey = "";
if (rallyApiKey != "") {
PropertiesService.getScriptProperties().setProperty("RallyApiKey", rallyApiKey);
} else {
rallyApiKey = PropertiesService.getScriptProperties().getProperty("RallyApiKey");
}
if (rallyApiKey == null) return null;
return {
headers: { "ZSESSIONID": rallyApiKey },
payload: payload,
method: method
};
}
I can't spot any problem.
Could you please help?
Thank you!

I thought that from your error message, the payload might be required to be sent as JSON data. If my guessing is correct, how about the following modification?
Modified script:
From:
return {
headers: { "ZSESSIONID": rallyApiKey },
payload: payload,
method: method
};
To:
return {
headers: { "ZSESSIONID": rallyApiKey },
payload: JSON.stringify(payload),
method: method,
contentType: "application/json"
};
Note:
In this modification, it supposes that the values of payload and rallyApiKey are valid values for using the API. Please be careful this.
When above modification was not the dierct solution of your issue, can you provide the official document of API you want to use? By this, I would like to confirm it.
Reference:
fetch(url, params) of Class UrlFetchApp
Thanks for the fast response.
With the following
var payload = {"ConversationPost":{"Artifact": "/portfolioitem/capability/"+objId,"Text": post}};
var method = "POST";
var options = optionsPost_(method, payload);
and
var options={
headers: { "ZSESSIONID": rallyApiKey },
payload: payload,
method: method,
contentType:"application/json"
};
It gives me
Cannot parse input stream due to I/O error as JSON document: Parse error: expected '{' but saw 'h' [ chars read = >>>h<<< ]
If I change it to
var options={
headers: { "ZSESSIONID": rallyApiKey },
payload: JSON.stringify(payload),
method: method,
contentType:"application/json"
};
It gives me
Cannot parse input stream due to I/O error as JSON document: Parse error: expected '}' but saw ',' [ chars read = >>>{"headers":{"ZSESSIONID":"_ycHaCSd2QZSf8kbkQ0R1yhjohUvSzUYas0caApHt2A"},<<< ]
Only documentation I use is this:
https://rally1.rallydev.com/slm/doc/webservice/objectModel.sp#ConversationPost
I can't find any difference but this actually started working.
I believe the problem was caused by combination of mistakes. I removed one problem but perhaps add another one.
Here is a code which works.
function createPost(objId, post) {
objId = '313878829908';
post = "<p>MindMap:Hello from GAS.</p>"
var url = "https://rally1.rallydev.com/slm/webservice/v2.0/conversationpost/create";
var payload = {'ConversationPost':{'Artifact': '/portfolioitem/capability/'+objId,'Text': post}};
var method = 'POST';
//var options = optionsPost_(method, payload);
var response = UrlFetchApp.fetch(url, optionsPost_(method, payload));
var content = JSON.parse(response.getContentText());
content.CreateResult.Errors.forEach(error => Logger.log(error));
}
function optionsPost_(method, payload) {
var rallyApiKey = "";
if (rallyApiKey != "") {
PropertiesService.getScriptProperties().setProperty("RallyApiKey", rallyApiKey);
} else {
rallyApiKey = PropertiesService.getScriptProperties().getProperty("RallyApiKey");
}
if (rallyApiKey == null) return null;
var options={
'headers': {'ZSESSIONID': rallyApiKey },
'payload': JSON.stringify(payload),
'method': method,
'contentType':'application/json'
};
return options;
}
Thanks Tanaike for your help. I really appreciate it.

how to download a pdf file from an url in angular 5

I currently spend one day in this issue,still failed to download a file from an url in angular 5
leadGenSubmit() {
return this.http.get('http://kmmc.in/wp-content/uploads/2014/01/lesson2.pdf',
{responseType:ResponseContentType.Blob}).subscribe((data)=>{
console.log(data);
var blob = new Blob([data], {type: 'application/pdf'});
console.log(blob);
saveAs(blob, "testData.pdf");
},
err=>{
console.log(err);
}
)
}
when I run above code it shows following error
ERROR TypeError: req.responseType.toLowerCase is not a function
at Observable.eval [as _subscribe] (http.js:2187)
at Observable._trySubscribe (Observable.js:172)
how can I solve this issue.Can any one post the correct code to download a pdf file from an url in angular 5?
I think you should define header and responseType like this:
let headers = new HttpHeaders();
headers = headers.set('Accept', 'application/pdf');
return this.http.get(url, { headers: headers, responseType: 'blob' });
Here is my simple solution to open a PDF based on an ID in Angular :
In my service, I created this method :
public findById(id?: string): Observable<Blob> {
return this.httpClient.get(`${this.basePath}/document/${id}`, {responseType: 'blob'});
}
Then in my component, I can do use this method (behind a button or whatever):
showDocument(documentId: string): void {
this.yourSuperService.findById(documentId)
.subscribe((blob: Blob): void => {
const file = new Blob([blob], {type: 'application/pdf'});
const fileURL = URL.createObjectURL(file);
window.open(fileURL, '_blank', 'width=1000, height=800');
});
}
Try this
let headers = new HttpHeaders();
headers = headers.set('Accept', 'application/pdf');
return this.http.get(url, { headers: headers, responseType: 'blob' as 'json' });

How to get the response after a POST request in CasperJS

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).

Getting no records when making Ajax request

I am trying to make a request to a server but im getting no records. When i run the code I am getting no error messages so I assume my code is working but when the callback function is executed on store load I just get a blank message.
var proxy = Ext.data.proxy.Ajax.create({
type:'ajax',
url:loginHostUri,
method:'POST',
headers:{
'Accept':'application/x-www-form-urlencoded'
},
extraParams:{
grant_type:'password',
username:username,
password:psswd,
client_id: consumerKey,
client_secret: consumerSecret
},
reader:{
type:'json',
root:''
}
});
var store = Ext.getStore('instance');
store.setProxy(proxy);
store.load({
callback:function(records,operation,success){
Ext.Msg.alert('INFO',records,Ext.emptyFn);
},
scope:this
});
The message is just blank but I know the Json response looks like this:
{
"":{
"id":"2332123",
"issued_at":"090342",
" instance_url":"instance",
"signature":"sig",
"access_token":"access"
}
}
define a fields or a model for the store
store.setFields({name: 'id', name: 'issued_id' ...});(put this before store.load())
Try that and console.log(records) under callback and reply back what you get...

Consuming an OData request in Sencha Touch with JSONP

I'm working on a Sencha Touch app and I want to use OData so I have been playing around with the netflix Odata service. When I send my request with JSONP in Sencha I can see the request come back when I trace it, however my callback function is never getting called. Can anyone help? Here is my code.
var blah = function () {
Ext.util.JSONP.request({
url: 'http://odata.netflix.com/catalog/Titles()',
callbackKey: 'callback',
params: {
$format: 'json',
$top: '10',
$filter: "startswith(Name,'C')",
$select: "ShortName"
},
callback: function (result) {
alert('asdf');
var data = result;
if (data) {
alert('data');
} else {
alert('There was an error during retrieving data.');
}
}
});
}
var button = new Ext.Button({
text: 'Ajax',
listeners: {
'tap': blah
}
});
Thanks in advance
If you're getting a syntax error on the server response quotes, this is a known issue described here for which there is an available update.
The server is returning XML, not JSON data.
