Javascript解析JSON字符串

Question

Folks，DynamoDB调用返回一个JSON对象，我想解析它，并获取密码哈希字段

jsonString = JSON.stringify(data)
console.log(jsonString)

输出：

{"Count":1,"Items":[{"token":{"S":"token"},"uid":{"S":"33c02130-66b5-11e3-bdb0-7d9889f293b5"},"password":{"S":"$2a$10$ervzJ.DWjHOXRtJSugTaWuquI2OvPLyipa4YXecc/2KdQnmhrHxr6"},"username":{"S":"foo"},"plate":{"S":"dinner"},"name":{"S":"Test Name"},"server":{"S":"bar"}}]}

我将如何解析此字符串，并检索“密码”字段？ 以下代码不起作用：

console.log(jsonString.password)
console.log(jsonString.uid)

以下内容返回undefined：

console.log(data.password);

谢谢！

这已经是一个对象了，所以你可以这样做：

var str = {"Count":1,"Items":[{"token":{"S":"token"},"uid":{"S":"33c02130-66b5-11e3-bdb0-7d9889f293b5"},"password":{"S":"$2a$10$ervzJ.DWjHOXRtJSugTaWuquI2OvPLyipa4YXecc/2KdQnmhrHxr6"},"username":{"S":"foo"},"plate":{"S":"dinner"},"name":{"S":"Test Name"},"server":{"S":"bar"}}]};

alert(str.Items[0].password.S);
