javascript - 无法正确访问 API 的响应

Question

我的 API 返回此响应:

{"__v":0,"short":"8xdn4a5k","_id":"5404db5ac27408f20440babd","branches":[{"version":1,"code":""}],"ext":"js","language":"javascript"}

这有效:

console.log(response.short);

但这会产生未定义:

console.log(response.branches.version);

怎么会这样？

Answer 1

branches response的属性(property)是一个数组:

"branches":<strong>[</strong>{"version":1,"code":""}<strong>]</strong>

因此，您必须访问 branches 的第一个元素(这是您正在寻找的对象)以获得 version属性:

response.branches[0].version
