如何将项目添加到JSON对象

标签： javascript arrays json node.js

我有以下 post 方法：

app.post('/sound', function (req, res) {

    var myYeArray = req.body;

    let retData = [];

    for (var i = 0; i < myYeArray['filter'].length; i++) {
        if (i > 3)
            break;

        var myEl = myYeArray['filter'][i];

        myPersSaveRevEntity.myPersSaveRevEntity(myEl, function (result) {
            console.log('GUID >>> ' + i + ' : ' + myEl['_myEntityGUID'] + ' >>> ' + JSON.stringify(result));

            Object.keys(result).forEach(function (key) {
                var row = result[key];
                // add items to retData
            });

        });
    }

    res.send(retData);
});

它得到一个具有数组JSON对象的 request ；数据库行列表。

我遍历JSON数组，并将每个组成JSON对象成功保存在远程数据库中。

我要失败的地方是我想创建一个JSON数组，并在持久性之后添加ach项，并将结果数组发送到 response 中。

方法myPersSaveRevEntity.myPersSaveRevEntity(myEl, function (result)返回最后一个持久表行：

GUID >>> 4 : 104 >>> [{"REMOTE_ENTITY_GUID":854,"LOCAL_ENTITY_GUID":101,"ENTITY_OWNER_GUID":119,"ENTITY_CONTAINER_GUID":100,"ENTITY_SITE_GUID":-1,"ENTITY_ACCESS_PERMISSION":0,"ENTITY_TYPE":"my_object","ENTITY_SUB_TYPE":"my_comment","COLUMN_NAME_CREATED_DATE":"Sat Aug 11 05:40:39 2018\n","COLUMN_NAME_UPDATED_DATE":"Sat Aug 11 05:40:39 2018\n"}]

我该如何完成？

谢谢大家。
