Rails，如何遍历发送到服务器的JSON对象

Question

我的应用程序将JSON对象返回到服务器，其结构如下:

contacts:[{"id":38,"full_name":"xxxxxxx","email":""},{"id":70,"full_name":"xxxxxxx","email":""},{"id":79,"full_name":"xxxx","email":""},{"id":22,"full_name":"xxxxxxx","email":""},{"id":48,"full_name":"xxxxxx","email":""},{"id":69,"full_name":"xxxxx","email":""}]

如何在控制器中，我可以循环遍历每个记录并获得记录。id、记录。full_name等。

谢谢

你的问题基本上是我如何将这个JSON字符串序列化成一个ruby对象(哈希)。你可以调用contacts=JSON.parse(json_string)，然后调用contacts[0].id，等等。
