我正在import java.util.Scanner;
public class Lab1Main {
public static void main(String[] args)
{
System.out.println("BMI Calculator");
// Start Scanner
Scanner input = new Scanner(System.in);
// Declare variables
String u_name;
Double u_age, u_feet, u_inches, u_weight;
// Create new HealthProfile
HealthProfile client = new HealthProfile();
// Start do-while
do {
// Enter name
System.out.print("Enter name or X to quit: ");
u_name = input.nextLine();
// Enter age
System.out.print("Enter your age: ");
u_age = Double.parseDouble(input.nextLine());
// Enter height (feet)
System.out.print("Enter your height(feet): ");
u_feet = Double.parseDouble(input.nextLine());
// Enter height (inches)
System.out.print("Enter your height(inches): ");
u_inches = Double.parseDouble(input.nextLine());
// Enter weight
System.out.print("Enter your weight: ");
u_weight = Double.parseDouble(input.nextLine());
// Set variables from HealthProfile
client.setName(u_name);
client.setAge(u_age);
client.setFeet(u_feet);
client.setInches(u_inches);
client.setWeight(u_weight);
// Display results
System.out.println("********** HEATLH PROFILE FOR " + client.getName() + " **********");
System.out.println("Age: " + client.getAge());
System.out.println("Weight: " + client.getWeight());
System.out.println("Height (in inches): " + client.getHeight());
System.out.println("Your BMI is : " + client.getBMI());
System.out.println("You are considered: " + client.getCategory());
System.out.println("Your max heart rate is: " + client.getMaxHR());
} while (u_name != "X");
System.out.println();
}// end main
}// end class
使用Ionic2 验证 Cordova中的用户。
我可以构建应用并在Firebase（iOS Simulator）上运行它。但是，只要我尝试使用Xcode使用以下代码登录用户：
ionic-native ("ionic-native": "2.2.11",) GooglePlus我收到以下错误：
2017-03-06 07：55：06.433 theWhoZoo [10489：868996] *** WebKit丢弃 一个未被捕获的例外 web视图：decidePolicyForNavigationAction：请求：帧：decisionListener： 代表： - [__ NSArrayM objectForKeyedSubscript：]：无法识别的选择器发送到实例 0x6100002471a0
更多信息：
我可以使用 loginGoogleCordova(): void {
GooglePlus.login(['public_profile', 'email']).then(googleData => {
let provider = firebase.auth.GoogleAuthProvider.credential(googleData.authResponse.accessToken);
firebase.auth().signInWithCredential(provider).then((data) => {
this.signIn(data);
});
}, error => {
this.loading.dismiss();
console.error('loginGoogle: ' + error);
this.doAlert('loginGoogle: ' + error.message);
});
}
在浏览器中成功验证用户。
AngularFire2任何帮助表示感谢。
