Brief Description

• Signature mechanism 和 Signature Example

Signature mechanism

Signature Key Generation Method

• Sort the request fields in the interface in ascending order based on their Ascii codes.
• Format it as key1=val1&key2=val2&key3=val3…&key=md5_secret_key.
• Encrypt the string generated in the previous step using MD5.

Signature Example

Example Request Parameters

{
  "amount": "100",
  "order_no": "ts3023423423",
  "key": "adesf235"
}

TypeScript Request Example

import * as crypto from 'crypto'

const payload = {
  amount: "100",
  order_no: "ts3023423423",
}

const secret = "adesf235" // md5秘钥

// 1. 排序（ASCII码升序）
const sortedKeys = Object.keys(payload).sort()

// 2. 拼接为 key1=val1&key2=val2... 的格式（不包含 key 字段）
const signingString = sortedKeys
  .filter(key => key !== 'key') // 去掉 key 字段
  .map(key => `${key}=${payload[key]}`)
  .join('&') + `&key=${secret}`

// 3. 进行 MD5 加密
const signature = crypto.createHash('md5').update(signingString).digest('hex')

console.log("签名前字符串:", signingString)
console.log("签名:", signature)
