来自 API 的登录请求

如何做React Native app一旦用户登录，那么它应该自动登录？一旦登录应用程序，它应该每次都能自动登录。

export default class LoginForm extends Component {
  state = {
    email: "",password: "",login: false,};
  uri = Info.BaseUri + Info.LoginEndPoint;
  # login request from API #
  login = () => {
    fetch(this.uri,{
      method: "POST",headers: {
        Accept: "application/json","Content-Type": "application/json",},body: JSON.stringify({
        identifier: this.state.email,password: this.state.password,}),})
      .then((response) => response.json())
      .then((data) => {
        if (data.user.email == this.state.email) {
          saveUser(data.jwt,data.user);
          this.props.navigation.navigate("Home");
        }
      })
      .catch(() => {
        alert("Email adresi veya parola hatalı!");
      });
  };
