Nuxt.js 在动态路由_id.vue里使用asyncData，为什么会执行2次？

Question

async asyncData(context) {
        console.log("asyncData runing");
        let categoryListData = await axios({
            method: "POST",
            url: api.categoryList,
            headers: {
                authorization: api.authCode,
                "Content-Type": "application/x-www-form-urlencoded;charset=UTF-8"
            },
            transformRequest: [data => Qs.stringify(data)],
            data: {}
        }).then(response => {
            let data = response.data;
            return data.data.rows;
        }).catch(error => {
            console.log("error:", error);
        });
        context.store.commit('getCategoryList', categoryListData)
        return;
    },

Answer 1

其实不是刷新两边，希望一下回答可以帮你解决问题我们也遇到的这样的情况 经过分析发现其实是界面上面有发送undefined请求，比如图片没请求到 奇怪吧，打个比喻；详情界面的url为：/article/_id;正常图片src="地址" 这个时候如果地址为undefined的话。浏览器就会发送一个/article/undefined的请求，说到这里应该就明白后面的执行内容了吧。巨坑，发现这个其实就意味着页面上面任何一个地方发生undefined就会导致页面重新请求，所以兄弟们，判空加起来吧！！
