我试图在 Javascript 中解析这个 json，但在 Node 中失败了。

 data = JSON.parse(body); //body is the json response
 dat = data["list"];

我从这里获取列表，但我该如何解析它？ JSON.stringify(dat) 也不起作用。

Answer 1

您需要像这样使用 for in 循环:

for (var id in data["list"]){
    console.log(id + " has given_url " +data["list"][id]["given_url"]);
}

如果您正在使用修改基本对象原型(prototype)的库，您可能还需要像这样的 hasOwnProperty 检查:

for (var id in data["list"]){
    if (data["list"].hasOwnProperty(id)){
        console.log(id + " has given_url " +data["list"][id]["given_url"]);
    }
}
