Question

我正在使用QNetworkReply向我的路由器接口发出简单的GET请求。基本上如果帖子数据为空，我发出GET，否则我会发出一个POST。让我们坚持GET

...
connect(nam,
        SIGNAL(finished(QNetworkReply*)),
        this,
        SLOT(finished(QNetworkReply*)));
...

void HttppostWindow::finished(QNetworkReply *reply)
{
    if(reply->error() == QNetworkReply::NoError)
    {
        ui->textEdit_result->setText(QObject::tr(reply->readAll()));
    }
    else
    {
        ui->textEdit_result->setPlainText(reply->errorString());
    }
}

现在

我在ui中给出答案。现在本地界面要求登录和pw。问题是使用GET命令检索的文本是如果用户输入了错误的密码，接口将显示的文本（autentication failed，请再试一次等等）。此外，使用代码nam-＆gt; head（request）我应该能够检索标头，但replyAll的内容是空的。

有什么想法吗？

Answer 1

在nam->head(request)之后，您不需要使用reply->readAll()。而不是这个，你应该使用如下方法：

QByteArray  rawHeader(const QByteArray &headerName) const;
QList<QByteArray> rawHeaderList() const;
const QList<RawHeaderPair> &rawHeaderPairs() const;

使用此方法，您可以查看head请求的内容。

此外，您的示例代码也有内存泄漏。您应该删除reply->deleteLater()广告位内的回复finished。

QNetworkReply行为在本地站点上进行身份验证
