Qt post request

[SGaist]

Hi,

Do you mean QNetworkAccessManager::post ?

[Raii]

yes we are doing a joint project with my friend, he wants 2 strings from me, I have to post them
I need to put 2 string in (class)model and send them

[SGaist]

Please describe your exact setup.

Because you could send these two strings as JSON data in one request, or split that in two.

I got it but I have a question for you
Why should I use QByteArray for post in Qt? Can't I use a direct class object instead?
QNetworkReply * post(const QNetworkRequest &request, QIODevice *data)
QNetworkReply * post(const QNetworkRequest &request, const QByteArray &data)
QNetworkReply * post(const QNetworkRequest &request, QHttpMultiPart *multiPart)

@Raii
You want to post a class object across the network? It doesn't make sense. You can post e.g. a QByteArray, you could think about serializing the object to bytes (e.g. see QDataStream) and deserialize at the other end, but not sure what you're trying to achieve.

@Raii said in Qt post request:

Because network layer sends bytes over network, it does not know anything about your classes (but you can serialise/deserialise your classes as @JonB mentioned).
But nothing stops you from converting your string into byte array:
https://doc.qt.io/qt-5/qstring.html#toLatin1
https://doc.qt.io/qt-5/qstring.html#toLocal8Bit
https://doc.qt.io/qt-5/qstring.html#toUtf8
Which method to use depends on the encoding of your string and what encoding you want to use to send the data.

@JonB

I can send it in c # windows form code example

class sendEmailAll
{


public String title { get; set; }
public String message { get; set; }

    public void sendMessage(sendEmailAll message) //send to class object 
    {
        using (var client = new HttpClient())
        {
            client.BaseAddress = new Uri("http://192.168.1.33:8081");
            client.DefaultRequestHeaders.Accept.Clear();
            HttpResponseMessage response = client.PostAsJsonAsync("/email/sendAll", message).Result; 
            
          // message is class object

        }
    }
}

@Raii
And your point is what? You are using PostAsJsonAsync. I think someone earlier said you can convert to JSON, which is what this is doing. @SGaist wrote

@JonB @SGaist
i need these two
i will pull the get as json and throw it into the model
I will also send a post, sometimes a parameter and sometimes a direct model

[SGaist]

Then write the methods that will marshal and unmarshal your classes to/from text. You can write QDataStream operators.
