data = JSON.parse(body); //body is the json response dat = data["list"];
我从这里得到的名单，但我怎么parsing这个？ JSON.stringify（dat）也不起作用。
你需要像这样使用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础对象原型的库，则可能还需要hasOwnProperty检查，如下所示：
for (var id in data["list"]){ if (data["list"].hasOwnProperty(id)){ console.log(id + " has given_url " +data["list"][id]["given_url"]); } }
