How I can pass for the textEdit something like:

Nome: Rodrigo
E-mail: ...

Nome: Diego
E-mail: ...

and not like in the img?
I've looked in some places for an example but nothing helped me.

My code:

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QtNetwork/QNetworkAccessManager>
#include <QtNetwork/QNetworkReply>
#include <QtNetwork/QNetworkRequest>
#include <QUrl>
#include <QUrlQuery>
#include <QMessageBox>
#include <QObject>
#include <QJsonDocument>
#include <QJsonObject>
#include <QJsonArray>
#include <QEvent>
#include <QDebug>
#include <QList>
#include <QString>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);


    QEventLoop eventLoop;
        QNetworkAccessManager manager;
        QObject::connect(&manager, SIGNAL(finished(QNetworkReply*)), &eventLoop, SLOT(quit()));
        QNetworkRequest req( QUrl( QString("http://localhost:3000/api/v1/contacts") ) );
        req.setRawHeader("X-User-Email", "rore@hotmail.com");
        req.setRawHeader("X-User-Token", "iHik3GFTy9xNrJotdsCb");

        QNetworkReply *reply = manager.get(req);
        eventLoop.exec();

        QString response = (QString)reply->readAll();

        //qDebug() << "Custom coordinate type:" << response;

        if (reply->error() == QNetworkReply::NoError) {
                QJsonDocument jsonResponse = QJsonDocument::fromJson(response.toUtf8());
                QJsonObject jsonObj = jsonResponse.object();
                QByteArray jsonString = jsonResponse.toJson(QJsonDocument::Indented);
               // qDebug() << "Custom coordinate type:" << jsonString;
                ui->textEdit->setText(jsonString);

                delete reply;
            }
        else {
           QMessageBox::critical(this, "ERROR:", reply->errorString());
            delete reply;
        }

   
}

MainWindow::~MainWindow()
{
    delete ui;
}

Hi,

Do you mean something like described here ?

RodrigoFBM

Hi. I think so. But in my Json I don't have something like

[
  **"properties":**
    {
        "created_at": "2018-01-08T22:10:32.235Z",
        "description": null,
        "email": "",
        "id": 1,
        "name": "Rodrigo",
        "phone": null,
        "updated_at": "2018-01-08T22:10:32.235Z",
        "user_id": 1
    },
    {
        "created_at": "2018-01-08T22:11:09.573Z",
        "description": null,
        "email": "",
        "id": 2,
        "name": "Diego",
        "phone": null,
        "updated_at": "2018-01-08T22:11:09.573Z",
        "user_id": 1
    }
]

for pass in jsonObject index like: .

QJsonArray jsonArray = jsonObject["properties"].toArray();

How I fix that?

SGaist

You have an array of dict. So extract that directly rather than an object.

RodrigoFBM

                QStringList names;
                QJsonDocument jsonResponse = QJsonDocument::fromJson(response.toUtf8());
                QJsonObject jsonObj = jsonResponse.object();
                QByteArray jsonArray = jsonResponse.toJson(QJsonDocument::Indented);

                foreach (const QJsonValue &value, jsonArray) {
                    QJsonObject obj = value.toObject();
                    names.append(obj["name"].toString());

                }
                 qDebug() <<names[0];

I tried it, but on debug console return just " ". What I did wrong?

SGaist

Why are you create a QByteArray ? You need a QJsonArray, see QJsonDocument::array.

RodrigoFBM

Yeah! It wroks! Thanks!

So...

        QEventLoop eventLoop;
        QNetworkAccessManager manager;
        QObject::connect(&manager, SIGNAL(finished(QNetworkReply*)), &eventLoop, SLOT(quit()));
        QNetworkRequest req( QUrl( QString("http://localhost:3000/api/v1/contacts") ) );
        req.setRawHeader("X-User-Email", "rodrigo_fbm@hotmail.com");
        req.setRawHeader("X-User-Token", "iHik3GFTy9xNrJotdsCb");

Is the most appropriate way to connect? If not, what is?

SGaist

Why the event loop ?

You can do the processing once your reply is finished.

RodrigoFBM

I looked up some examples on Google, and they were like that. I looked for something more current, but it did not work. In this case, what should I do?

SGaist

What did not work ?
