Question

您如何从此JSON中获取下面显示的变量“ outputSpeech”？我认为此JSON中的警告使我无法接受。有关使用其他格式不同的其他JSON的工作示例，请参见背景。

 await getRemoteData('https://api.coinmarketcap.com/v2/listings/')
      .then((response) => {enter code here
        const data = JSON.parse(response);
        outputSpeech = `This is the name ${data[2].name} man look at that on a saturday morning.`;
      })

---------------------------
 // API LINK 

{
    "attention": "WARNING: This API is now deprecated and will be taken offline soon.  Please switch to the new CoinMarketCap API to avoid interruptions in service. (https://pro.coinmarketcap.com/migrate/)", 
    "data": [
        {
            "id": 1, 
            "name": "Bitcoin", 
            "symbol": "BTC", 
            "website_slug": "bitcoin"
        }, 
        {
            "id": 2, 
            "name": "Litecoin", 
            "symbol": "LTC", 
            "website_slug": "litecoin"
        }, 
        {
            "id": 3, 
            "name": "Namecoin", 
            "symbol": "NMC", 
            "website_slug": "namecoin"
        },  
}

这是两个工作示例，它们来自两个JSONS，格式与上面的示例不同。

-------------------------------

这是第一个工作示例。
$ {data.BTC_BCN.last}

  await getRemoteData('https://poloniex.com/public?command=returnTicker')
      .then((response) => {
        const data = JSON.parse(response);
        outputSpeech = `This is the name ${data.BTC_BCN.last} man look at that on a saturday morning.`;
      })

这是下面的API链接。

https://poloniex.com/public?command=returnTicker

{"BTC_BCN":{"id":7,"last":"0.00000017","lowestAsk":"0.00000017","highestBid":"0.00000016","percentChange":"0.00000000","baseVolume":"5.47653442","quoteVolume":"34062281.36436343","isFrozen":"0","high24hr":"0.00000017","low24hr":"0.00000016"},"BTC_BTS":{"id":14,"last":"0.00001003","lowestAsk":"0.00001005","highestBid":"0.00001002","percentChange":"0.01827411","baseVolume":"2.53412366","quoteVolume":"252139.05854697","isFrozen":"0","high24hr":"0.00001017","low24hr":"0.00000986"},


--------------------------------

这是工作示例2。

 await getRemoteData('https://api.coinmarketcap.com/v1/ticker/')
      .then((response) => {
        const data = JSON.parse(response);
        outputSpeech = `This is the name ${data[2].name} man look at that on a saturday morning.`;
      })

这是下面的API链接。

Answer 1

 await getRemoteData('https://api.coinmarketcap.com/v2/listings/')
      .then((response) => {
        const data = JSON.parse(response);
        outputSpeech = `This is the name ${data.data[2].name} man look at that on a `enter code here`saturday morning.`;
      })

像魅力一样工作！！ “ $ {data.data [2] .name}”

从解析的JSON中提取具有JSON格式的数据，像这样？
