【问题描述】:
我使用 React Redux 并创建了一个登录函数,但我需要在成功登录后获取回调返回并将用户重定向到页面。
我尝试将函数作为参数传递但不工作。
dispatch 操作后如何获得回报?
Login fun
export const login = (request,cb) => {
return dispatch => {
let url = "/api/user/login";
axios({
method: "post",
url: url,
data: request,
config: { headers: { "Content-Type": "multipart/form-data" } }
})
.then(response => {
let authState = {
isLoggedIn: true,
user: response.data
};
cb();
window.localStorage["authState"] = JSON.stringify(authState);
return dispatch({
type: "USER_LOGIN_FULFILLED",
payload: { userAuthData: response.data }
});
})
.catch(err => {
return dispatch({
type: "USER_LOGIN_REJECTED",
payload: err
});
});
};
};
提交
handleLogin(e) {
this.setState({ showLoader: true });
e.preventDefault();
const request = new Object();
if (this.validator.allValid()) {
request.email = this.state.email;
request.password = this.state.password;
this.props.login(request, () => {
//get callbach here
this.props.history.push('/my-space/my_views');
})
this.setState({ showLoader: false });
} else {
this.setState({ showLoader: false });
this.validator.showMessages();
this.forceUpdate();
}
}
const mapStateToProps = state => {
return {
authState: state
};
};
const mapDispatchToProps = dispatch => {
return {
login: request => dispatch(login(request))
};
};
export default connect(mapStateToProps, mapDispatchToProps)(LoginForm);
