无法进行C＃Restful身份验证（API Key / Secrete正确）

Question

我想将经过身份验证的JS（下面）的REST请求转换为C＃代码 - 使用RestSharp lib（如图所示）我似乎没有正确构建签名。请帮忙..

休息响应通过＆＃34;无效的API密钥＆＃34; （确认密钥/密钥正确无误）保持响应

// sample code using the crypto lib to build the RESTFUL request
const crypto = require('crypto')
const request = require('request')

const apiKey = 'test'
const apiSecret = 'test'
const url = 'version/auth/abc'
const nonce = Date.now().toString()
const body = {}
const rBody = JSON.stringify(body)

// try build the RESTFUL signature here using crypto lib and use sha384

// Not quite sure what's the update does here though.
let signature = `/api/${url}${nonce}${rBody}`
signature = crypto
  .createHmac('sha384', apiSecret)
  **.update(signature)**
  .digest('hex')

// all code above is fine. And this is the sample code only, and trying to do something same in C# and have tried the following. I believe is the way create the "signature" issue.

我已经在下面编写了C＃代码，但是没有工作，请指出，我猜这个签名建筑是不正确的。

// sample code using the crypto lib to build the RESTFUL request
const crypto = require('crypto')
const request = require('request')

const apiKey = 'test'
const apiSecret = 'test'
const url = 'version/auth/abc'
const nonce = Date.now().toString()
const body = {}
const rBody = JSON.stringify(body)

// try build the RESTFUL signature here using crypto lib and use sha384

// Not quite sure what's the update does here though.
let signature = `/api/${url}${nonce}${rBody}`
signature = crypto
  .createHmac('sha384', apiSecret)
  **.update(signature)**
  .digest('hex')

// all code above is fine. And this is the sample code only, and trying to do something same in C# and have tried the following. I believe is the way create the "signature" issue.

希望这很清楚。提前谢谢。
