Besically, I post my username and password to a site, say http://example.org/signup.asp. Then I get cookies from it, which I wanna save it in qnam_, an object of QNetworkAccessManager.
Problem 1
The first issue is, after saving the cookies in reply_'s corresponding url, say say http://example.org/signup.asp, I just cannot retrieve it back via http://example.org/ or http://example.org/something_else.
auto cookies = qvariant_cast<QList<QNetworkCookie>>(reply_->header
(QNetworkRequest::SetCookieHeader));
auto cookieJar = new QNetworkCookieJar(&qnam_);
// qDebug() outputs "http://example.org/sign.asp"
qDebug() << reply_->request().url();
// assert won't fire, which means "one or more cookies are set for url"
assert(cookieJar->setCookiesFromUrl(cookies, reply_->request().url()));
qnam_.setCookieJar(cookieJar);
// qDebug() outputs nothing, but "()", why???
qDebug() << qnam_.cookieJar()->cookiesForUrl(QUrl("http://example.org"));
Problem 2
The second one is even I set cookies in the "root hostname", say http://example.org/, I still cannot retrieve it via the same url.
assert(cookieJar->setCookiesFromUrl(cookies, QUrl("http://example.org")));
qnam_.setCookieJar(cookieJar);
// Still get nothing from it.
qDebug() << qnam_.cookieJar()->cookiesForUrl(QUrl("http://example.org"));
Note that I've checked the QT HTTP Post issue when server requires cookies and How do I save cookies with Qt?, which doesn't work out I think.
Any ideas? Thanks!
I got this working using the following solution:
in the function callback for QNetworkReply::finished I add a cookie
QNetworkCookie cookie("mycookie", mycookiedata.toUtf8());
QList<QNetworkCookie> cookies;
cookies.append(cookie);
mCookieJar.setCookiesFromUrl(cookies, reply->url());

Using AngleSharp v 0.9.9, I'm loading a page with OpenAsync which sets a bunch of cookies, something like:
var configuration = Configuration.Default.WithHttpClientRequester().WithCookies();
var currentContext = BrowsingContext.New(configuration);
// ....
var doc = context.OpenAsync(url, token);
This works fine and I can see the cookies have been set. For example, I can do this:
var cookieProvider = currentContext.Configuration.Services.OfType<ICookieProvider>().First() as MemoryCookieProvider;
And examine it in the debugger and see the cookies in there (for domain=.share.state.nm.us)
Then I need to submit a post:
var request = new DocumentRequest(postUrl);
request.Method = HttpMethod.Post;
request.Headers["Content-Type"] = "application/x-www-form-urlencoded";
request.Headers["User-Agent"] = userAgent;
//...
Which eventually gets submitted:
var download = loader.DownloadAsync(request);
And I can see (using Fiddler) that it's submitting the cookies from the cookieProvider.
However, I need to add a cookie (and possible change the value in another) and no matter what I try, it doesn't seem to include it. For example, I do this:
cookieProvider.Container.Add(new System.Net.Cookie()
{
Domain = ".share.state.nm.us",
Name = "psback",
Value = "somevalue",
Path = "/"
});
And again I can examine the cookieProvider in the debugger and see the cookie I set. But when I actually submit the request and look in fiddler, the new cookie isn't included.
This seems like it should be really simple, what is the correct way to set a new cookie and have it included in subsequent requests?
I think there are two potential ways to solve this.
either use document.Cookie for setting a new cookie (would require an active document that already is at the desired domain) or
Use a Filter for getting / manipulating the request before its send. This let's you really just change the used cookie container before actually submitting.
The Filter is set in the DefaultLoader configuration. See https://github.com/AngleSharp/AngleSharp/blob/master/src/AngleSharp/ConfigurationExtensions.cs#L152.
I want read value from cookie using Java code.
Example:
I have store value in cookie . like email=abc#xyz.com
When I am trying to fetch email value from cookie using below code I am only get "abc". But I want full value "abc#xyz.com"
I am using below code
Cookie[] cookies = renderRequest.getCookies();
for (int i = 0; i < cookies.length; i++) {
Cookie cookie = cookies[i];
System.out.print("Name : " + cookie.getName( ) + ", ");
System.out.println("Value: " + cookie.getValue( ));
}
I'm not sure if the RenderRequest gives you the same cookies as the HttpServletRequest: After all, it's a portlet-request. If you have set the value yourself, and you're not getting the same value back, you probably made a mistake encoding the value when you set it.
Also, as you're obviously in a render request handler, that might be the request of someone who is logged in anyway, and there's no need to set a specific cookie: You can just get the value for the currently signed in user (unless you're looking for somebody else's mail address - however that gets stored in the cookie)
I debug my API using Xdebug and PHPStorm's debugging features. For this to work, the client needs a cookie named XDEBUG_SESSION.
When using Postman, I used to use a Chrome extension to add this cookie, and Postman's cookie interception feature to get this to work in Postman (since it's a sandboxed app).
However, I cannot create cookies in Paw. So, as a workaround, I modified the API response cookie to have the key as XDEBUG_SESSION and value as PHPSTORM, and debugging worked fine. However, this is not ideal as I would also like to set the expiry date to something far in the future (which I can't in Paw).
So, my questions are:
Is there a way to add custom cookies in Paw?
If not, is there a way to to edit the expiry date for an existing cookie (considering that name, value, domain and path are editable)?
Are there any other alternatives to achieve my objective?
I just managed to achieve this exact thing to debug my APIs with Paw (2.1.1).
You just have to Add a Header with the name Cookie and a value of Cookies picked from the dropdown that will appear. You then have to insert a Cookie named XDEBUG_SESSION with a value of PHPSTORM inside the Cookies value of the header just created.
To be more clear, you can see it in the screenshot below:
I messed around with it to see if I could create an extension. I wasn't able to, and the below does not work but thought I'd share in case anyone knows the missing pieces.
First off, there is no extension category (generator, dynamic value, importer) that this functionality falls into. I tried to make use of the dynamic value category but was unsuccessful:
CookieInjector = function(key, value) {
this.key = "XDEBUG_SESSION";
this.value = "PHPSTORM";
this.evaluate = function () {
var f = function (x,y) {
document.cookie=this.key+"="+this.value;
return true;
}
return f(this.key, this.value);
}
// Title function: takes no params, should return the string to display as
// the Dynamic Value title
this.title = function() {
return "Cookie"
}
// Text function: takes no params, should return the string to display as
// the Dynamic Value text
this.text = function() {
return this.key+"="+this.value;
}
}
// Extension Identifier (as a reverse domain name)
CookieInjector.identifier = "com.luckymarmot.PawExtensions.CookieInjector";
// Extension Name
CookieInjector.title = "Inject Cookie Into Cookie Jar";
// Dynamic Value Inputs
CookieInjector.inputs = [
DynamicValueInput("key", "Key", "String"),
DynamicValueInput("value", "Value", "String")
]
// Register this new Extension
registerDynamicValueClass(CookieInjector);
The main thing stopping this from working is I'm not sure how the request is built in PAW and not sure how to attach the cookie. I've looked through the documentation here: https://luckymarmot.com/paw/doc/Extensions/Reference/Reference, and can't find what I need.
i need to get web sites html status codes
today i just do simple get request to the domain , and then i get the status code as part of the response , but also the site index.html content .
pNetworkManager = new QNetworkAccessManager(this);
reply = pNetworkManager->get(request);
QVariant vStatusCodeV = reply->attribute(QNetworkRequest::HttpStatusCodeAttribute);
QVariant redirectionTarget = reply->attribute(QNetworkRequest::RedirectionTargetAttribute);
data=reply->readAll();
this last function i like to avoid if it can be avoided ,
is there any way to get only the domain status code ?
Maybe you can send a HEAD request instead of a GET request?
This is not a Qt / client specific solution, but is the approach recommended by the HTTP protocol when you don't need the content, but just want to get the headers that a request would normally produce, for example in order to validate that the page exists.
I suppose this could be done with QNetworkAccessManager using the head() method
I agree with #shevron's answer, but if the site you're communicating with isn't "clever" enough to implement the HEAD request, you can still avoid the readAll() call.
QByteArray line = reply->readLine(); //< eg "HTTP/1.0 200 OK"
QList<QByteArray> chunks = line.split(' ');
QString statusCode = chunks[1];
That should avoid the memory overhead of readAll().
I use the following code to perform sub-request in HMVC structure:
A request to "page1" will make a sub-request to "page2" by the following code:
$request = Request::factory('/page2')
->method(Request::POST)
->post($postData)
->execute();
The execution in "page2" will add / change the value of a cookies item by
setcookie('new_var', $newValue);
Now I need to capture the new value of the cookie "new_var" in "Page1". So how can I do that?
PS: Due to some limitations, I have to set the 'new_var' in cookie, so putting it to session is not an answer.
==========update =============
As suggested by zerkms, I did something like this:
$response = Request::factory('/page2')
->method(Request::POST)
->post($postData);
//before
error_log(print_r($response->cookie(), TRUE));
$response->execute();
//after
error_log(print_r($response->cookie(), TRUE));
the result of the "before" and "after" log entries are both empty array. :(
In kohana you'd better used Response::cookie() method.
In this case you can use this method for both retrieving and setting cookies (even in the same request)
