QNetworkReply::RemoteHostClosedError

Question

但是，当我提交我的问题时，“调试控制台”说

QNetworkReply::RemoteHostClosedError

(我捕获了错误)。

我不知道为什么，请帮帮我！

Code on Github

void MainWindow::on_pushButton_2_clicked()
{
    QString id = ui->ID_Send->text();
    QJsonObject JJ;
    QJsonDocument jd;
    JJ["title"] = ui->Title->text();
    JJ["body"] = ui->Comment->toPlainText();
    QHttpMultiPart *part = new QHttpMultiPart(QHttpMultiPart::FormDataType);
    QHttpPart info;
    info.setHeader(QNetworkRequest::ContentTypeHeader, QVariant("text/json"));
    jd.setObject(JJ);
    info.setBody(jd.toJson());
    part->append(info);

    QNetworkRequest request;
    qDebug()<<"https://api.github.com/repos/MoyuSteve/Comment/issues?client_id="+
              client_id+"&client_secret="+client_secret;
    request.setUrl(QUrl("https://api.github.com/repos/MoyuSteve/Comment/issues?client_id="+
                        client_id+"&client_secret="+client_secret));
    QNetworkReply* reply = manager->post(request,part);
    QObject::connect(reply, &QNetworkReply::finished, [reply, this] () {
        if (reply->error() == QNetworkReply::NoError) {
            ui->status->setText("ok");
        } else {
            ui->status->setText("failed");
            qDebug()<<reply->error();
        }
        reply->deleteLater();
    });
}

您可以以in this answer或here为例。

与您的代码相比，它将标头设置为"application/json"。

并且它使用QNetworkAccessManager来发送网络请求和接收回复。

QUrl url("https://api.github.com/repos/" + owner +"/" + project + "/tags");
qInfo() << url.toString();
QNetworkRequest request(url);
request.setHeader(QNetworkRequest::ContentTypeHeader, "application/json");
QNetworkAccessManager nam;
QNetworkReply * reply = nam.get(request);
