【英文标题】：Converting the javascript object to json object [duplicate]

【问题描述】：

我正在创建一个 logMessage 对象。

logMessage = function (msg, severity, vendorId, userName, actionPerformed, priority, traceId, dataSent) 
    this.message = msg;
    this.severity = severity;
    this.vendorId = vendorId;
    this.userName = userName;
    this.actionPerformed = actionPerformed;
    this.priority = priority;
    this.traceId = traceId;
    this.dataSent = dataSent;
;

var msg = new logMessage(err, "High", "none", qry.username, "Error on login call: /req/login", "high", "", qry);
Utility.writeToLoggly(msg);

err ,qry 是 json 对象；如何将 msg 对象转换为 json 对象？ 我将msg 对象发送到loggly 以进行日志管理。如果我能将格式正确的 json 对象发送到 loggly，那就太好了。

【问题讨论】：

JSON.stringify(msg)

注意：按照约定，JS“类”以大写字母开头。

附注谷歌搜索“javascript json 输出”很容易产生几个带有正确答案的页面。

顺便说一句：没有 JSON object 这样的东西。 JSON 是一个字符串。

【参考方案1】：

logMessage = function (msg, severity, vendorId, userName, actionPerformed, priority, traceId, dataSent) 
    this.message = msg;
    this.severity = severity;
    this.vendorId = vendorId;
    this.userName = userName;
    this.actionPerformed = actionPerformed;
    this.priority = priority;
    this.traceId = traceId;
    this.dataSent = dataSent;
;

var msg = new logMessage(err, "High", "none", qry.username, "Error on login call: /req/login", "high", "", qry);
Utility.writeToLoggly(JSON.stringify(msg));

【参考方案2】：

您可以使用 JSON.stringify() 函数，因此只需添加到您的代码中：

Utility.writeToLoggly(JSON.stringify(msg));
