javascript - 结果已声明，但其值从未在 ionic 3 上读取

Question

我有以下代码

async register(user: User){
try {
  const result = await this.afAuth.auth.createUserWithEmailAndPassword(user.email, user.password);
  this.userRegister();
}
catch {
  this.showAlert();
}

但是当我运行命令 ionic build --release --prod 时，终端会告诉我以下消息

  tslint: C:/Users/Mike/Desktop/GuiaCorretor/src/pages/register/register.ts, line: 39
      'result' is declared but its value is never read.

    try {
      const result = await this.afAuth.auth.createUserWithEmailAndPassword(user.email, user.password);
      this.userRegister();

Answer 1

我认为它是在提示您没有对结果变量做任何事情。尝试只是做await this.afAuth.auth.createUserWithEmailAndPassword(user.email, user.password); 代替。听起来像是 linter 错误而不是编译器错误

要禁用规则(来自 tslint)，您可以更新它:
