作法:通过RStudio的新订单Binance API

本文介绍了作法:通过RStudio的新订单Binance API的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试使用RStudio通过Binance API创建新订单.

I am trying to create a new order via the Binance API using RStudio.

我找到了Binance官方API文档，并发现我应该使用

I found the Binance Official API Docs and figured out that I should use

POST /api/v3/order (HMAC SHA256).

以下脚本对我不起作用:

The following script doesn't work out for me:

url='https://api.binance.com/api/v3/account'

GET(url,
    add_headers("X-MBX-APIKEY"= *[my API key]*),
    query=list("symbol"="ETHBTC",
               "side"="BUY",
               "type"="MARKET",
               "quantity"=1,
               recvWindow=5000,
               "timestamp"=1499827319559,
               "signature"=**???**),
    verbose())

有人知道我在做什么错吗，如何使用RSTUDIO通过Binance API创建订单以及如何创建签名?

Does anyone know what I'm doing wrong and how I can create an order via the Binance API using RSTUDIO and how I can create my signature?

推荐答案

library(httr)

timestamp <-
  as.character(jsonlite::fromJSON(content(
    GET("https://api.binance.com/api/v1/time"), "text"
  ))$serverTime + 999)

query <-
  list(
    "symbol" = "VENBTC",
    "side" = "BUY",
    "type" = "MARKET",
    "quantity" = 1,
    "recvWindow" = 5000,
    "timestamp" = timestamp
  )

signature <-
  digest::hmac(
    key = "*[my secret key]*",
    object = paste(names(query), query, sep = "=", collapse = "&"),
    algo = "sha256"
  )

POST(
  url,
  add_headers("X-MBX-APIKEY" = "*[my API key]*"),
  query = c(query, signature = signature),
  verbose()
)
