【中文标题】如何在一个 GET 请求中解析来自 Coinbase API 的所有股票代码

【英文标题】：How to parse all ticker symbols from Coinbase API in one single GET request

【问题描述】：

我正在尝试在来自 Coinbase REST API 的单个 JSON 有效负载响应中获取所有代码（货币对）及其相应的买价和卖价数据。如果我对每个单独的股票代码都有 GET 请求，我将不得不避免收到 Coinbase API 文档中提到的 729 错误。

我对此 URL 有一个 GET 请求 -> https://api-public.sandbox.pro.coinbase.com/products/BTC-USD/book

它返回了我需要的 BTC-USD 数据，但实际上我对交易所列出的所有代码感兴趣，并在一次查询中获得相应的买价和卖价数据。

例如，许多其他交易所将货币代码首字母缩写词替换为“ALL”。所以我的 JSON 有效负载响应如下所示：

我尝试设置一个计时器函数来一次解析单个代码 3 秒，但这不是从 JSON 获取我需要的所有数据的最快方法。

JSON 响应应如下所示：

【问题讨论】：

不幸的是，并非每个交易所都支持一次查询多个市场的能力...

【参考方案1】：

您似乎无法在一次调用中获取所有代码 ((我还没有时间重新构建网络套接字的基础设施。Coinbase 是唯一一个不允许在一次通话中接收所有代码的交易所。我从 Bittrex、Bitmex、Kraken、Bitfinex、Binance 获得报价 - 并且没有一次性获取所有代码的问题。

祝你好运！

【参考方案2】：

来自Coinbase docs：他的 URL 将为 Coinbase 上的所有代码提供数据：

curl --request GET \
     --url https://api.exchange.coinbase.com/products \
     --header 'Accept: application/json'

如果您需要有关每个代码的更详细数据，您可以遍历响应并对每个代码名称进行单独调用。
