获取所有名称
json
答案 1 :(得分:0)
您可以使用public class Main extends Application {
@Override
public void start(Stage primaryStage) {
try {
//BorderPane root = new BorderPane();
Parent root =
FXMLLoader.load(getClass().getResource("/fxml/Contrlpanel.FXML"));
Scene scene = new Scene(root,487,406);
scene.getStylesheets().add(getClass().getResource("/fxml/application.css").toExternalForm());
primaryStage.setScene(scene);
primaryStage.show();
} catch(Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) {
launch(args);
}}
或json
模块。
例如:
ast
或
import json
value = """[{"Id":2,"Name":"Sony","WarehouseName":"Bangalore"},{"Id":3,"Name":"JBL","WarehouseName":"Nanjangud"},{"Id":4,"Name":"Skull Candy 2","WarehouseName":"Mysore"},{"Id":5,"Name":"Skull Candy 3","WarehouseName":"Mysore"}]"""
print( json.loads(value) )
输出:
import ast
value = """[{"Id":2,"Name":"Sony","WarehouseName":"Bangalore"},{"Id":3,"Name":"JBL","WarehouseName":"Nanjangud"},{"Id":4,"Name":"Skull Candy 2","WarehouseName":"Mysore"},{"Id":5,"Name":"Skull Candy 3","WarehouseName":"Mysore"}]"""
print( ast.literal_eval(value) )
print( map(lambda x: x["Name"], ast.literal_eval(value)) )
