Question

我收到以下错误。

Error: Argument "data" is not a valid Document. Input is not a plain JavaScript object.

我使用下面的代码创建文档

var docRef = this.dbManager.collection('tetst).doc(subjectId);
        var setAlan = docRef.set(EntryEntity.toJSON);

我在toJSON方法中有以下代码

public toJSON(): testEntry {
        let returnJSON = {
            "entry_id": this.entry_id,
            "subject_id": this.subject_id,
            "entry_date": this.entry_date,
            "questionnaire": this.questionnaire,
            "entry_start_timestamp": this.entry_start_timestamp,
            "entry_end_timestamp": this.entry_end_timestamp,
            "entry_complete": this.entry_complete,
            //"responses": this.responses,
            "last_answered_question" : this.last_answered_question,
            "entry_status" : this.entry_status
        }

        return returnJSON;
    }

我在上面的方法中构建了json对象。如果我打印json对象，我将得到低于内容

{entry_id：＆＃39; df2b4ad4-6a70-4304-a71f-3a63773ada61＆＃39;， subject_id：＆＃39; ABwppHHkzfY1Whp-lCHNnvEcuqvsbMKtZsg_ui9vc4jtpXSiAbh0fNsg6LxGkYq-Va3SOrwcvD-HAs7VQA＆＃39;， entry_date：＆＃39; 2018-06-15＆＃39;，问卷：1， entry_start_timestamp：＆＃39; 2018-06-15T09：38：10.266Z＆＃39;， entry_end_timestamp：＆＃39; 2018-06-15T09：38：10.266Z＆＃39;， entry_complete：false， last_answered_question：0， entry_status：＆＃39;有效＆＃39; }

如何解决上述问题？ json对象有什么问题吗？

Answer 1

您需要调用toJSON方法。当您需要传递被调用方法的返回值时，您正在将方法的引用传递给set。

更改

var setAlan = docRef.set(EntryEntity.toJSON);

到

var setAlan = docRef.set(EntryEntity.toJSON());

参数＆＃34;数据＆＃34;不是有效的文件。输入不是普通的JavaScript对象
