QtWebKit QWebPage::acceptNavigationRequest and POST data - post

is it possible to access POST data at this (QWebPage::acceptNavigationRequest) moment? I wish to peek at request's POST data there because I locked navigation and I don't have the opportunity at NetworkAccessManager::createRequest because that it not reached.
Thanks!

Are you the one creating the request? If you're making the request, you should be able to see the POST data. If it's a webpage that you didn't create making the request, you should use another tool like Wireshark to look at the data sent to the server.

yes it is possible simply overwrite the QNetworkAccessManager::createRequest
Member to:
QNetworkReply * networkaccessman::createRequest ( Operation op, const QNetworkRequest & req, QIODevice * outgoingData )
{if(outgoingData){
qDebug()<<"%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%";
qDebug()<<outgoingData->peek(1000000);
}
return QNetworkAccessManager::createRequest ( op, req, outgoingData );
}

Access session value in gatling checks

I use gatling to send data to an ActiveMQ. The payload is generated in a separate method. The response should also be validated. However, how can I access the session data within the checks
check(bodyString.is()) or simpleCheck(...)? I have also thought about storing the current payload in a separate global variable, but I don't know if this is the right approach. My code's setup looks like this at the moment:
val scn = scenario("Example ActiveMQ Scenario")
.exec(jms("Test").requestReply
.queue(...)
.textMessage{ session => val message = createPayload(); session.set("payload", payload); message}
.check(simpleCheck{message => customCheck(message, ?????? )})) //access stored payload value, alternative: check(bodystring.is(?????)
def customCheck(m: Message, string: String) = {
// check logic goes here
}
Disclaimer: providing example in Java as you don't seem to be a Scala developper, so Java would be a better fit for you (supported since Gatling 3.7).
The way you want to do things can't possibly work.
.textMessage(session -> {
String message = createPayload();
session.set("payload", payload);
return message;
}
)
As explained in the documentation, Session is immutable, so in a function that's supposed to return the payload, you can't also return a new Session.
What you would have to do it first store the payload in the session, then fetch it:
.exec(session -> session.set("payload", createPayload()))
...
.textMessage("#{payload}")
Regarding writing your check, simpleCheck doesn't have access to the Session. You have to use check(bodyString.is()) and pass a function to is, again as explained in the documentation.

How to retrieve Medium stories for a user from the API?

I'm trying to integrate Medium blogging into an app by showing some cards with posts images and links to the original Medium publication.
From Medium API docs I can see how to retrieve publications and create posts, but it doesn't mention retrieving posts. Is retrieving posts/stories for a user currently possible using the Medium's API?
The API is write-only and is not intended to retrieve posts (Medium staff told me)
You can simply use the RSS feed as such:
https://medium.com/feed/#your_profile
You can simply get the RSS feed via GET, then if you need it in JSON format just use a NPM module like rss-to-json and you're good to go.
Edit:
It is possible to make a request to the following URL and you will get the response. Unfortunately, the response is in RSS format which would require some parsing to JSON if needed.
https://medium.com/feed/#yourhandle
⚠️ The following approach is not applicable anymore as it is behind Cloudflare's DDoS protection.
If you planning to get it from the Client-side using JavaScript or jQuery or Angular, etc. then you need to build an API gateway or web service that serves your feed. In the case of PHP, RoR, or any server-side that should not be the case.
You can get it directly in JSON format as given beneath:
https://medium.com/#yourhandle/latest?format=json
In my case, I made a simple web service in the express app and host it over Heroku. React App hits the API exposed over Heroku and gets the data.
const MEDIUM_URL = "https://medium.com/#yourhandle/latest?format=json";
router.get("/posts", (req, res, next) => {
request.get(MEDIUM_URL, (err, apiRes, body) => {
if (!err && apiRes.statusCode === 200) {
let i = body.indexOf("{");
const data = body.substr(i);
res.send(data);
} else {
res.sendStatus(500).json(err);
}
});
});
Nowadays this URL:
https://medium.com/#username/latest?format=json
sits behind Cloudflare's DDoS protection service so instead of consistently being served your feed in JSON format, you will usually receive instead an HTML which is suppose to render a website to complete a reCAPTCHA and leaving you with no data from an API request.
And the following:
https://medium.com/feed/#username
has a limit of the latest 10 posts.
I'd suggest this free Cloudflare Worker that I made for this purpose. It works as a facade so you don't have to worry about neither how the posts are obtained from source, reCAPTCHAs or pagination.
Full article about it.
Live example. To fetch the following items add the query param ?next= with the value of the JSON field next which the API provides.
const MdFetch = async (name) => {
const res = await fetch(
`https://api.rss2json.com/v1/api.json?rss_url=https://medium.com/feed/${name}`
);
return await res.json();
};
const data = await MdFetch('#chawki726');
To get your posts as JSON objects
you can replace your user name instead of #USERNAME.
https://api.rss2json.com/v1/api.json?rss_url=https://medium.com/feed/#USERNAME
With that REST method you would do this: GET https://api.medium.com/v1/users/{{userId}}/publications and this would return the title, image, and the item's URL.
Further details: https://github.com/Medium/medium-api-docs#32-publications .
You can also add "?format=json" to the end of any URL on Medium and get useful data back.
Use this url, this url will give json format of posts
Replace studytact with your feed name
https://api.rss2json.com/v1/api.json?rss_url=https://medium.com/feed/studytact
I have built a basic function using AWS Lambda and AWS API Gateway if anyone is interested. A detailed explanation is found on this blog post here and the repository for the the Lambda function built with Node.js is found here on Github. Hopefully someone here finds it useful.
(Updating the JS Fiddle and the Clay function that explains it as we updated the function syntax to be cleaner)
I wrapped the Github package #mark-fasel was mentioning below into a Clay microservice that enables you to do exactly this:
Simplified Return Format: https://www.clay.run/services/nicoslepicos/medium-get-user-posts-new/code
I put together a little fiddle, since a user was asking how to use the endpoint in HTML to get the titles for their last 3 posts:
https://jsfiddle.net/h405m3ma/3/
You can call the API as:
curl -i -H "Content-Type: application/json" -X POST -d '{"username":"nicolaerusan"}' https://clay.run/services/nicoslepicos/medium-get-users-posts-simple
You can also use it easily in your node code using the clay-client npm package and just write:
Clay.run('nicoslepicos/medium-get-user-posts-new', {"profile":"profileValue"})
.then((result) => {
// Do what you want with returned result
console.log(result);
})
.catch((error) => {
console.log(error);
});
Hope that's helpful!
Check this One you will get all info about your own post........
mediumController.getBlogs = (req, res) => {
parser('https://medium.com/feed/#profileName', function (err, rss) {
if (err) {
console.log(err);
}
var stories = [];
for (var i = rss.length - 1; i >= 0; i--) {
var new_story = {};
new_story.title = rss[i].title;
new_story.description = rss[i].description;
new_story.date = rss[i].date;
new_story.link = rss[i].link;
new_story.author = rss[i].author;
new_story.comments = rss[i].comments;
stories.push(new_story);
}
console.log('stories:');
console.dir(stories);
res.json(200, {
Data: stories
})
});
}
I have created a custom REST API to retrieve the stats of a given post on Medium, all you need is to send a GET request to my custom API and you will retrieve the stats as a Json abject as follows:
Request :
curl https://endpoint/api/stats?story_url=THE_URL_OF_THE_MEDIUM_STORY
Response:
{
"claps": 78,
"comments": 1
}
The API responds within a reasonable response time (< 2 sec), you can find more about it in the following Medium article.

ios swift 2.1 - unable to send Patch request with body

I'm trying to write a http rest client for my webservice and i need to send some PATCH requestes with data in the body.
I'm using the JUST library for sending requests ( https://github.com/JustHTTP/Just )
My express application just doesn't see the request.
Here's some code (i'm testing in playground, and everything went fine with other kind of requests like put, post...)
headers = ["accept":"application/json","content-type":"application/json","authorization":"key"] //key is ok
var data = ["id":3, "quantity":6]
var r = Just.patch("http://api.marketcloud.it/v0/carts/1233", headers:headers, data:data) //1233 is a cart Id
print(r)
print(r.json)
The method Just.patch returns an HTTPResult Object.
this says 'OPTIONS http://api.marketcloud.it/v0/carts/13234 200'
Also this object should contain a json, but it's 'nil'.
On the server-side, my express applications doesn't receive the request (it just logs an 'OPTION', but nothing else).
Could this be a playground-related problem? Or a just-related one?
Thanks for any suggestion
I managed to contact the library's author via twitter and he fixed the bug and answered me in less than 24h!
Here's the new release of the library.

FacebookRealtimeUpdateController Override Post and return 'OK'

Using Mvc.Facebook.Realtime the FacebookRealtimeUpdateController provides a process for handling user events (HandleUpdateAsync) , but not for page events.
Microsoft.AspNet.Mvc.Facebook.Realtime Namespace
I have managed to process page events by overriding the 'POST'
Public Overrides Function Post() As Task(Of Net.Http.HttpResponseMessage)
Dim content = Request.Content
Dim jsonContent As String = content.ReadAsStringAsync().Result
Dim ConvertedJson As RealTimeEvent = JsonConvert.DeserializeObject(Of RealTimeEvent)(jsonContent)
' Do something with the page events
Return MyBase.Post
End Function
However Facebook resends all events immediately , which I believe is because I am not returning a '200 OK' back to Facebook. (See quote)
First you'll need to prepare the page that will act as your callback URL. This URL will need to be accessible by Facebook servers, and be able to receive both the POST data that is sent when an update happens, but also accept GET requests in order to verify subscriptions.
This URL should always return a 200 OK HTTP response when invoked by Facebook.
I wiresharked my server and I do not see a 200 OK HTTP response, so I believe this something to do with the way I am overloading the post.
Can I somehow return an OK response from my overridden function or maybe it would be better to drop the whole Microsoft.AspNet.Mvc.Facebook.Realtime solution and just handle the Subscription GETs and Posts from facebook myself?
Update: I turned off "only my own code' and I can see an exception occurring in the AspNet.MVC.Facebook.dll.
So new question, How do I isolate this exception?
For others looking.
The issue was actually the HandleUpdateAsync function which must be overridden. This is fired after the 'Post'
If you don't return a valid task the exception is thrown inside AspNet.MVC.Facebook.dll and Facebook is never given a 200 OK.
I was using This blog on how to use the FacebookRealtimeUpdateController but in that version the 'HandleUpdateAsync' does not return a task and the processing is done in the function.
So by creating a task that does nothing , everything appears to be working fine.
Public Overrides Function HandleUpdateAsync(notification As ChangeNotification) As Task
Dim newtask As New Task(New System.Action(Sub()
Dim x As String = ""
End Sub))
Return newtask
End Function
Edit: But it creates a massive memory leak which cannot be cleared even with recycling..
So the real solution is to just create your own controller and forget the FacebookRealtimeUpdateController completely.
Very easy to do and saves allot of hassle!

HTTPClient GetAsync post object

We currently have a generic MVC method that GET's data from ASP.NET Web API
public static T Get<T>(string apiURI, object p)
{
using (HttpClient client = new HttpClient())
{
client.BaseAddress = new Uri(Config.API_BaseSite);
HttpResponseMessage response = client.GetAsync(apiURI).Result;
// Check that response was successful or throw exception
if (response.IsSuccessStatusCode == false)
{
string responseBody = response.Content.ReadAsStringAsync().Result;
throw new HttpException((int)response.StatusCode, responseBody);
}
T res = response.Content.ReadAsAsync<T>().Result;
return (T)res;
}
}
Our question is:- obviously, we can not send 'p' as you would with a post,
client.PostAsync(apiURI, new StringContent(p.ToString(), Encoding.UTF8, "application/json")
but how we go about sending this object / JSON with a get.
We have seen sending it as part of the URL, however, is there an alternative?
GET sends the values with the query string (end of url), in regards to "but how we go about sending this object / JSON with a get. We have seen sending it as part of the URL, however, is there an alternative?".
The alternative is POST or PUT.
PUT is best used when the user creates the key/url. You can look at examples such as cnn.com - where the URL's are just short versions of the article title. You want to PUT a page at that URL.
Example:
http://newday.blogs.cnn.com/2014/03/19/five-things-to-know-for-your-new-day-wednesday-march-19-2014/?hpt=hp_t2
has the url of "five-things-to-know-for-your-new-day-wednesday-march-19-2014", which was generated from the article title of "Five Things to Know for Your New Day – Wednesday, March 19, 2014"
In general, you should follow these guidelines:
Use GET when you want to fetch data from the server. Think of search engines. You can see your search query in the query string. You can also book mark it. It doesn't change anything on the server at all.
Use POST when you want to create a resource.
Use PUT when you want to create resources, but it also overwrites them. If you PUT an object twice, the servers state is only changed once. The opposite is true for POST
Use DELETE when you want to delete stuff
Neither POST nor PUT use the query string. GET does
