egg session 取值 undefined

[ChunrunHan]

controller 里面存储
// 获取验证码
async getCaptcha(){
const {ctx} = this;
var captcha = ctx.service.user.getCaptcha();
ctx.session.code = captcha.text; // session 存储
console.log('session 存储',ctx.session.code)
ctx.body = captcha.data;
}

service里面打印ctx.session.code 为 undefined，为什么？？？？？？
// 检查验证码是否正确
checkCaptcha(code){
const {ctx} = this;
code = code.toLowerCase()
console.log("sessionCode",ctx.session.code) // undefined???????
let sessCode = ctx.session.code? ctx.session.code.toLowerCase():null
console.log("sesscode",sessCode)
//验证
if(code === sessCode){
// 成功之后验证码作废
ctx.session.code = null
}
return code === sessCode;
}
