我想要返回twitter用户的followers_count。当我向api发出get请求时，我返回的是JSON：
编辑：响应有多个部分我希望从开头提取数据的部分如下：

如何仅提取followers_count键值对。因为这是我需要的唯一部分。我可能会选择其他人，但这是主要部分。 我尝试过这样的事情：
console.log(response.body['followers_count']);
但那不起作用。

简短回答是：
var responseObject = JSON.parse(response);
console.log(responseObject[0].followers_count)
请注意，您在上面粘贴的字符串作为响应不是有效的JSON，但我认为它是复制/粘贴中的错误。您可以使用online json validator对其进行测试。

response[0].followers_count;这会有用。
