http请求postman vs angular

Question

有一个带有方法的角项目：

createUSer() {
  let params = new HttpParams()
  params.append("email","sdfsd@sdsvvvvdf.com")
  params.append("password","sdfdfd121")

  this.htpClien.get(this.baseUrsl+"createEmployee",
  {params:params}).subscribe(sub=>{
  })
}

和我的firebase函数中的函数：

exports.createEmployee = functions.https.onRequest((request, response)=>{

    if (request.method === 'GET') {

        let email = request.query.email;
        let password = request.query.password;

            admin.auth().createUser({
                email: email,
                emailVerified: false,
                password: password,
                disabled: false
            }).then(succes => {
                response.send(succes.uid)
            }).catch(er => {
                response.send(er)
            })        
    }
});

通过“postman”进行测试时，一切都按照应有的方式进行，但是当我通过Angular解决它时，我会收到电子邮件和密码的“未定义”值...我做错了什么？：S
