调用gitlab api问题

Question

调用gitlab api上传文件至仓库中，下面的代码不知道哪里有问题，不能实现需求。有没有朋友帮忙看看是哪里的问题，或者重新写一下

QString Url = "http://************/";
    QString privateToken = "*************************";
    int projectId = 15011;
    QString filePath = "1.xlsx";
    QString branch = "main";
    QString commitMessage = "Update file";
    QString content = "New content of the file";


    QString apiUrl = Url + "api/v4/projects/" + QString::number(projectId) +
        "/repository/files/" + filePath;

    QJsonObject params;
    params["branch"] = branch;
    params["id"] = 150;
    params["file_path"] = "1.xlsx";
    params["commit_message"] = commitMessage;
    params["content"] = content;

    QByteArray jsonData = QJsonDocument(params).toJson();

    CURL* curl = curl_easy_init();
    if (curl) {
        struct curl_slist* headers = nullptr;
        headers = curl_slist_append(headers, ("PRIVATE-TOKEN: " + privateToken).toUtf8().constData());

        curl_easy_setopt(curl, CURLOPT_URL, apiUrl.toUtf8().constData());
        curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
        curl_easy_setopt(curl, CURLOPT_POSTFIELDS, jsonData.constData());

        CURLcode res = curl_easy_perform(curl);
        if (res != CURLE_OK) {
            qDebug() << "Error: " + QString(curl_easy_strerror(res));
        }
        qDebug() << "File updated successfully.";
        curl_slist_free_all(headers);
        curl_easy_cleanup(curl);
        
    }
    qDebug() << "Failed to initialize libcurl.";

请求接口还有其他信息可以获取的吧，只能拿到code吗，看看能不能拿到msg等提示信息。
