我有一个从离子应用程序中的api端点获取数据的服务。这是从服务器获取数据的功能。
getDriverInfo(username)
{
return this.http.get(this.base_url + 'user/' + username, {
headers: new HttpHeaders().set('Authorization', 'Bearer ' + this.access_token)
});
}
我有一个获取数据响应的页面。
handleResponse(data) {
this.db.getDriverInfo(data.username).subscribe(
resp => {
this.driverData = resp;
this.driverId = this.driverData.driver.id;
this.driverUserid = this.driverData.id;
console.log(this.driverData);
}
);
this.token.handle(data.access_token);
this.navCtrl.setRoot(HomePage, {
driverData: this.driverData,
driverId: this.driverId,
driverUserId: this.driverUserId
});
}
toDash()
{
let loading = this.loadCtrl.create({
content:'Logging In...'
});
loading.present();
this.auth.login(this.form).subscribe(
data => {
this.handleResponse(data);
loading.dismiss();
},
error => {
this.handleError(error);
loading.dismiss();
}
);
}
console.log()this.driverData给了我数据。
在我的首页中,我尝试将数据保存在像这样的变量中
constructor(public navCtrl: NavController, public platform: Platform,
public geo: Geolocation, public loadingCtrl: LoadingController,
public driverProvider: DriverProvider, public alertCtrl: AlertController,
public navParams: NavParams, public modalCtrl: ModalController, public db: DbProvider
) {
this.driverDetails = this.navParams.get('driver_data');
this.driverUserId = this.navParams.get('driver_user_id');
this.driverDBId = this.navParams.get('driver_id');
this.isOnline = this.navParams.get('isOnline');
console.log(this.driverDetails);
}
但是console.log给了我未定义的信息。我如何有效地传递数据?
答案 0 :(得分:1)
在HomePage
中更改以下内容:
this.driverDetails = this.navParams.get('driver_data');
对此:
this.driverDetails = this.navParams.get('driverData');
将数据发送到第二页时,您使用的是属性driverData
,因此,要接收此属性,您需要将其完全添加到get()
要获取所有数据,可以在构造函数中执行以下操作:
this.allData = this.navParams.data;
console.log(this.allData);
