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] } ],
[
'body',
'{"trade_id":53067029,"price":"125.24","size":"0.07555643","time":"2019-12-
27T17:04:37.429725Z","bid":"125.23","ask":"125.24","volume":"55843.38198278"}'
]
]

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;
});
