JS - 对象到数组到 Google 表格 batchUpdate

Question

我已经为此努力了几天，似乎正在取得进展，但我无法找出错误。目标：从本地服务器查询，将结果存储到一个数组，该数组可以发送到 google 工作表 batchUpdate 的 "values" 属性。

我对整个异步的事情感到厌烦，但我想我现在已经掌握了 Promises 并且它有点工作......

到目前为止，我的代码如下所示：

function begin(auth) {

var theArray = [];

let getResults = (passedQuery) => {
    return new Promise((resolve, reject) => {
        client.connect();
        var sql = client.query(passedQuery);

        sql.on('row', (row, result) => {
            result.addRow(row);
        });

        sql.on('end', (result) => {
            resolve(result.rows); // Array.from(result.rows)??
            client.end();
        });

    });
}

// may not even need this...    
let convertArray = (sqlObj) => {
    return new Promise((resolve, reject) => {

        theArray = Object.keys(sqlObj).map((k) => {
            return [sqlObj[k]];
        });

        console.log(theArray);

        // sqlObj.forEach((element) => {
        //     theArray.push(element);
        // })

        // theArray = sqlObj.reduce((result, item) => {
        //     var key = Object.keys(item)[0]; // first property
        //     result[key] = item[key];
        //     return result;
        // }, []);

        // console.log(theArray);            
        resolve(theArray);

        // while (sqlObj.length) {
        //     theArray.push(sqlObj.splice(0, sqlObj.length));
        //     console.log(sqlObj.length);
        // }            
        // console.log('convertArray should be done and now includes: \n'+JSON.stringify(theArray));

        // resolve(theArray);
    });
}

let updateSheets = (myArray) => {
    return new Promise((resolve, reject) => {

        var update_range = "Sheet1!A:Z";
        var valueInputOption = "RAW";
        var sheets = google.sheets('v4');

        var options = {
            auth: auth,
            spreadsheetId: spreadsheetId,
            resource: {
                valueInputOption: valueInputOption,
                data: [
                    {
                        range: update_range,
                        majorDimension: "COLUMNS",
                        // values: [[JSON.stringify(myArray,null,' ')]] // stringify and it works...in 1 cell...
                        values: myArray // this should be values only! NO KEYS / COLUMN HEADERS
                    }
                ]
            }
        }

        sheets.spreadsheets.values.batchUpdate(options, (err, res) => {
            if (err) {
                reject(err);
            } else {
                console.log(res);
                resolve(res);
            }
        });
    });
}

getResults('SELECT item_number,item_descrip1 FROM item WHERE item_number LIKE \'23-%\' LIMIT 10')
    .then((sqlObj) => {
        console.log('Converting object to array...hopefully...');
        return convertArray(sqlObj);
    })
    .then((convertedObj) => {
        console.log('Updating sheets...');


           return updateSheets(convertedObj);
        })
        .catch((error) => {
            console.log('Something went wrong...\n%s', error);
        })
}

你可以从我的评论中看到，我一直在尝试各种方法让对象进入 [x]D 数组（基于查询返回的列数）

事实上，我的结果...

我相当确信 batchUpdate 调用无法理解数组中的 'keys'，但我尝试删除它仍然会得到类似的结果。

一位同事能够为我提供这个问题的答案。我正在为后代分享为我实现此功能的结果。

    let convertArray = (sqlObj) => {
    return new Promise((resolve, reject) => {

        var result = [];

        if (sqlObj.length > 0) {
            var order = Object.keys(sqlObj[0]).map(function (k) {
                return k;
            });
            console.log(order);
            var result = [];
            for (var i = 0; i < sqlObj.length; ++i) {
                result.push(order.map(function (k) {
                    return sqlObj[i][k];
                }));
            }
        }
        console.log(result);

        resolve(result);
    });
}
