无法使用 Reddit API 通过仅应用程序 OAuth 检索访问令牌

Question

所以我阅读了linkhttps://github.com/reddit-archive/reddit/wiki/OAuth2下面的文档。我正在尝试为我的应用程序检索一个访问令牌，它只需要一个仅应用程序 OAuth，因为它不需要用户插入他们的凭据。我已按照上述页面上的说明进行操作，但我无法检索访问令牌，而且我总是得到：

"{\"message\": \"Unauthorized\", \"error\": 401}"

这是我的代码：

#include "reddit.h"

#include <QtNetwork>
#include <QUuid>

const QString GRANT_URL  = "https://oauth.reddit.com/grants/installed_client";
const QString ACCESS_TOKEN_URL = "https://www.reddit.com/api/v1/access_token";
const QByteArray CLIENT_IDENTIFIER = "MYID";

Reddit::Reddit(QObject *parent) : QObject(parent)
{
    mDeviceID = "DO_NOT_TRACK_THIS_DEVICE";
    mAuthHeader = "Basic " + CLIENT_IDENTIFIER.toBase64();
}

void Reddit::getAccessToken()
{
    auto netManager = new QNetworkAccessManager(this);

    QUrl requestUrl = buildAccessTokenUrl();
    QNetworkRequest netRequest(requestUrl);
    netRequest.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");
    netRequest.setRawHeader("Authorization", mAuthHeader);

    auto reply = netManager->post(netRequest, requestUrl.query(QUrl::FullyEncoded).toUtf8());
    connect(reply, &QNetworkReply::finished, this, &Reddit::accessTokenRequestFinished);
}

void Reddit::accessTokenRequestFinished()
{
    auto reply = qobject_cast<QNetworkReply*>(sender());
    qDebug() << reply->readAll();

    reply->deleteLater();
}

QUrl Reddit::buildAccessTokenUrl()
{
    QUrl url(ACCESS_TOKEN_URL);

    QUrlQuery urlQuery;
    urlQuery.addQueryItem("grant_type", GRANT_URL);
    urlQuery.addQueryItem("device_id", mDeviceID);
    url.setQuery(urlQuery);

    return url;
}

我已使用 "installed" 类型选项在 https://ssl.reddit.com/prefs/apps/ 注册了我的应用程序。

好的，所以我找到了问题。我没有阅读 'Basic' HTTP Authentication Scheme 并且忘记了我的授权 header 中的 : 我修改为：

mAuthHeader = "Basic " + (CLIENT_IDENTIFIER + ":").toBase64();
