当我将其转换为对象并执行类似的操作时
"streamData.streams.game" 它给了我一个错误，当我查看 json 查看器时，它似乎是一个数组，因为它有一个 0，但是我不确定如何选择正确的。我非常坚持这一点，我不知道如何在流中选择任何值。
【问题讨论】：
-
你不能使用循环吗？或者如果你知道索引直接访问它
streamData.streams[0].game -
是的，流是一个数组。 JSON 字面意思是“Javascript 对象表示法”，在
"streams":之后可以看到开头的[ -
我猜前两个帖子已经解释过了。流是一个数组。您必须像 streamData.streams[i].game 一样获取它，其中 'i' 可以是数组长度之间的任何值。这是最基本的根本！一票否决！
