VUEJS data.map不是一个函数

我正在使用VueJS并收到一条我之前没有过的错误消息。事件var是一个数组,所以它应该可以工作吗?

在我的HTML文件中,我包括:

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.1.10/vue.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue-resource/1.2.0/vue-resource.js"></script>

当我记录response.data的输出时,我看到一个数组:

未捕获(承诺)TypeError:response.data.map不是函数       在Vue 3美元。 (main.js:17)

var app = new Vue({
    el: '#app',
    data: {
        responders: [],
        incidents: []
    },

    mounted: function () {
        this.getIncidents();
    },

    methods: {
        getIncidents: function() {
            console.log('getIncidents');
            var app = this;
            this.$http.get('/api/v1/incidents').then(function(response) {
                // set data on vm
                var incidentsReceived = response.data.map(function (incident) {
                    return incident
                });
                Vue.set(app, 'incidents', incidentsReceived);
            });
        }
})

您无法映射响应。尝试将响应数据设置为您的数据,

this.$http.get('/api/v1/incidents').then((response) => {
                // set data in your data object
                this.incidents = response.data
                // Now you can map over the incidents and return 
                return this.incidents.map(incident => return)
            });
