当用户使用电子邮件/密码成功验证时,我需要重定向到另一个页面(组件),否则,在div上显示警告消息,指出电子邮件或密码不正确。
这是我的代码:
constructor (props) {
super(props);
this.state = {
// name: "",
cnx_mail: '',
cnx_pwd: '',
joinByEmail: '',
items: [],
token : '',
redirectToReferrer:false,
errors: {},
formErrors: {cnx_mail: '', cnx_pwd: ''},
emailValid: false,
passwordValid: false,
formValid: false
}
this.handleUserInput = this.handleUserInput.bind(this);
this.handleSubmit = this.handleSubmit.bind(this);
}
handleSubmit = (event) => {
event.preventDefault();
fetch(`${API}/api/connexion`, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify ({
email: this.state.cnx_mail,
password: this.state.cnx_pwd,
})
})
.then(res => res.json())
.then(json => {
console.log(json);
localStorage.setItem('toktok', json.result);
console.log(json[0].role);
//i have to verify email/password bedore redirection
window.location.href="/accounts";
});
}
这是我在render()中的表单:
<form className="demoForm" onSubmit={this.handleSubmit} noValidate encType="application/x-www-form-urlencoded">
<div className="alreadysubscribed-input">
<div className={`alreadysubscribed-field group-input ${this.errorClass(this.state.formErrors.cnx_mail)}`}>
<input type="email" required className="form-control fatb-input input-form" name="cnx_mail"
value={this.state.cnx_mail}
id="cnx_mail"
onChange={this.handleUserInput} error={errors.cnx_mail} />
<label className="fatb-label" htmlFor="cnx_mail">Email</label>
<div className="fatb-bar"></div>
</div>
<div className={`alreadysubscribed-field group-input ${this.errorClass(this.state.formErrors.cnx_pwd)}`}>
<input type="password" required className="form-control fatb-input input-form" name="cnx_pwd"
value={this.state.cnx_pwd}
id="cnx_pwd"
onChange={this.handleUserInput} error={errors.cnx_pwd} />
<label className="fatb-label" htmlFor="cnx_pwd">Mot de passe</label>
<div className="fatb-bar"></div>
</div>
</div>
<FormErrors formErrors={this.state.formErrors} />
<div className="btn-cnx">
{/* <span className="mas">Se connecter</span> */}
<button className="fatb-btn bubbly-button btn-anim3 w100p" type="submit" name="cnx_btn" disabled={!this.state.formValid}>se connecter</button>
</div>
</form>
我需要验证角色是否==“ admin”,然后重定向到/ accounts,否则例如在div中显示警告消息。
这是我的数据的结构:
{
"success": true,
"message": "SUCCESS",
"result": [
{
"dateCreation": "2019-10-09T21:54:18.491Z",
"resetpasswordtoken": null,
"resetpasswordexpires": null,
"role": "admin",
"enable": true,
"_id": "5d9e67772682971c1fc3711c",
"email": "[email protected]",
"password": "$2b$10$HqEMSkaWBZ..BFvSpxliUu/02vWodvxYoFZMaYUU5ZsBeqeZB4jLu",
"tickets": [],
"gains": [],
"__v": 0,
"nom": "ACHEMLAL",
"prenom": "MERYEM",
"tel": "+33619562721"
},
{
"dateCreation": "2019-10-09T21:54:18.491Z",
"resetpasswordtoken": null,
"resetpasswordexpires": null,
"role": "admin",
"enable": true,
"_id": "5d9e677e2682971c1fc3711d",
"email": "[email protected]",
"password": "$2b$10$Bg4nOrNMzc.b/JBNKNiRP.BiMd/.h4CHKiy0nvV/uim0d3VwHl9iq",
"tickets": [],
"gains": [],
"__v": 0
},
........
对于重定向页面,您可以编写代码window.location.href
,如下所述。
componentDidMount() {
const token = localStorage.getItem('toktok');
fetch(`${API}/api/accounts`,{
headers :{
'authorization': `Bearer ${token}`,
}
})
.then(results => {
return results.json();
})
.then(data => {
this.setState({ items: data.result });
window.location.href="/nextpageurl";
})
.catch(err => {
console.log("error : ",err);
});
}
您将不得不使用一个库来满足您的路由需求。一些流行的是反应路由器,到达路由器etc。从哲学上进行反应,既没有考虑使用哪个路由器,也没有附带它。
假设:您正在使用react-router
然后。
.then(data => {
this.setState({ items: data.result });
this.props.history.push('/nextpage');
})
尝试使用history.push
像这样:this.props.history.push('/ RedirectTargetComponent');
