我尝试在 Alfresco Enterprise 4.1.5 的 javascript 控制台中使用带有 json 字符串或 json 对象作为参数的jsonUtils.toObject方法，并得到以下错误。

参考：

http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Freferences%2Fapi-ws-obj-jsonUtils.html

toObject(jsonString) 接受 JSON 字符串并将其转换为原生 JavaScript 对象。

toObject(jsonObject) 获取 JSON 对象并将其转换为原生 JavaScript 对象。

测试 1

var jsonString = '{"test": "test"}';
logger.log( jsonUtils.toObject(jsonString) );

错误：

您不能在 JSON 字符串中使用单引号，必须使用双引号。因此，您在上面的测试 1中的代码应该可以在您在控制台之外运行的 Web 脚本中运行。

var jsonString = '{"test": "test"}';
logger.log( jsonUtils.toObject(jsonString) );

当在控制台中运行相同的代码时，您仍然会抛出异常，即

10080062 TypeError：找不到对象的默认值。（b7b11bfd779a718cabdce9ea9162012f.js#5）

这看起来特定于JavaScript 控制台，所以请在那里提出问题。

哦，显然你可以在此期间继续使用eval()。如果您从 Alfresco 来源或您控制的来源获取数据，那么这是相对安全的。
