原理： https://jwt.io/

API

jwt.sign(body[, secret])

Get the token

parameters:

• body {Object} The data to be encrypted
• [secret] {String} The operation secret, default: 'zfx'

Success will return:

• res {Object} response info, including
  • status {token} token

example:

// Sign with default algorithm HMAC SHA256
const token = jwt.sign({
  username: 'zfx',
  role: 'admin'  // get from database by captcha and password
}, 'zfx');
console.log(token)

jwt.verify(body[, secret])

verify the token

parameters:

• body {Object} The body gets from token
• [secret] {String} The operation secret, default: 'zfx'

Success will return:

• res {Boolean} pass or not

const pass = jwt.verify({
  username: 'zfx',
  role: 'admin', 
  signature: 'xxx'
}, 'zfx');
console.log(pass)

以koa为框架做测试

run server

node ./test/app

get token with method post(put data in body)

post http://localhost:3000/v1/api/geToken

getUserInfo(put token in header)

get http://localhost:3000/v1/api/getUserInfo
