Question

我的JSON响应如下：

"channels": {
            "BB0AC397-78AA-41C9-818A-A52A6BC81E9B": {

                "id": "BB0AC397-78AA-41C9-818A-A52A6BC81E9B",
                "name": "MyVABotChannel",
            },
            "94612845-7868-4B1C-8E58-7BD88869B197": {

                "id": "94612845-7868-4B1C-8E58-7BD88869B197",
                "name": "System_Bot_Test",


            }

我的要求是提取名称为MyVABotChannel的结构的id。当它们来自服务器时，id不是固定的和随机的。那么如何找到与特定名称对应的id。

Answer 1

假设javascript

此代码段假定使用＆＃34; MyVABotChannel＆＃34;

多个条目

// response = JSON
var values = Object.values(response.channels);
var botChannels = values.filter(channel => channel.name === "MyVABotChannel");

此代码段假设一个条目为＆＃34; MyVABotChannel＆＃34;

// response = JSON
var values = Object.values(response.channels);
var botChannels = values.find(channel => channel.name === "MyVABotChannel");

Answer 2

如果它在JavaScript或任何公开JSON DOM的库中，那么就像这样：

var channels = ...

var key = Object
    .getKeys( channels )
    .find( e => chanels[e].name == "MyVABotChannel" );

if( key == null ) {
    console.log("Couldn't find element.");
    return;
}

var result = channels[key].id;
console.log( result );
