您不能在 Promise 中传递“this”，您需要将“this”添加到变量中。

示例：

var app = new Vue({
       el: '#app',
       data: {
         message: 'Nawfal Kharbouch',
         experiences:[]
       },
       methods:{
        var self = this;
        getExperiences:function(){
            axios.get('http://localhost:8080/getexperiences').then(response=>{
                self.experiences=response.data;
                console.log(self.experiences);
            }).catch(function(error){
                console.log('erros : ',error);
            })  
        }
       },
        mounted:function(){
        this.getExperiences();
        console.log(this.experiences);
         }
    })
