如何使用NodeJS coinbase pro api从主体密钥获取价格？我正在尝试使用api命令

从body键获取价格

getProductTicker

以下是我到目前为止的内容，但是我不知道如何解析正文键的价格。

   const CoinbasePro = require('coinbase-pro');
   const publicClient = new CoinbasePro.PublicClient();

        publicClient.getProductTicker('ETH-USD', function(err, obj) {
        console.log('ETH-USD it worked');

        console.log('Start of Entries\n');
        console.log(Object.entries(obj));
        console.log('End of Entries \n');
        console.log('Start of keys\n');
        console.log(Object.keys(obj));
        console.log('End of keys \n');

}）;

下面是输出。我正在尝试从主体键获取价格。

  _ended: true,
  _callbackCalled: true
}
],
[ 'toJSON', [Function: responseToJSON] ],
[ 'caseless', Caseless { dict: [Object] } ],
[

您需要解析主体，因为主体将以字符串形式出现。我不确定toJson方法是否也可以使用，但值得尝试。试试这个。

const CoinbasePro = require("coinbase-pro");
const publicClient = new CoinbasePro.PublicClient();

publicClient.getProductTicker("ETH-USD", function(err, obj) {
  const parsedBody = JSON.parse(obj.body);
  const price = parsedBody.price;
});
