GDAX API 与 R：无效签名

Question

我拼命想让 GDAX API 与 R 一起工作。但是我总是收到消息 "invalid" signature.

当我使用 public API 时，无需签名，我可以毫无问题地使用 APi。

这是我的代码

library(httr)
library(jsonlite)
library(digest)
library(RCurl)

api.key <- "My API Key"
secret <- "MY API secret"
passphrase <- "my passphrase"

url <- "https://api.gdax.com"

timestamp <- format(as.numeric(Sys.time()), digits=13)
method <- "GET"
requestPath <- paste0(url,"/accounts")

dec.key <- base64Decode(secret , mode = "raw")

message <- paste0(timestamp,toupper(method),requestPath)

signature <- base64Encode( hmac(key = dec.key, object = message, algo = 
"sha256" , raw=T))

content( GET(requestPath,
         add_headers(
           "CB-ACCESS-KEY" = api.key, 
           "CB-ACCESS-SIGN" = signature,
           "CB-ACCESS-TIMESTAMP" = timestamp,
           "CB-ACCESS-PASSPHRASE" = passphrase,
           "Content-Type"="application/json")) )

这是关于如何构建签名的说明（来自 GDAX）

有人知道我做错了什么吗？谁能帮忙？谢谢

下面，我还 post vebose() 输出。因为这可能会有所帮助。

我还尝试了不同的 API 密钥/签名/密码（意思是我删除了 API 密钥并生成了一个新密钥。然后再次尝试）

非常感谢任何帮助。

您必须使用 as requestPath 将消息编码为 GDAX API 描述中的路径。在这种情况下：

requestPath <- "/accounts"
fullPath <- paste0(url, requestPath)

请记住使用完整路径作为 API 的 URL 端点。

content(GET(fullPath,
     add_headers(
       "CB-ACCESS-KEY" = api.key, 
       "CB-ACCESS-SIGN" = signature,
       "CB-ACCESS-TIMESTAMP" = timestamp,
       "CB-ACCESS-PASSPHRASE" = passphrase,
       "Content-Type"="application/json")))
