showing [object Object] 显示而不是对象属性

Question

我正在使用 Strapi 创建 Api 端点并使用 expressjs 使用这些端点。这一切都是为了教育目的。

除了在浏览器中显示对象属性外，一切正常。端点是 http://localhost:1337/restaurants 以 json 格式显示我的数据：

[{"_id":"5cf19dd4a774126e9ca7f4fd","name":"Strapi Restaurant 1","description":"Strapi restaurant is a cosy restaurant delivering one of the very fastest and nicest dining experiences in the world, combining nods to tradition with fierce modernity, warmth with daring.\n# Strapi restaurant #\n- \n- \n1. \n2. \n3.

我的快速路由使用 axios 访问 api 并且响应显示在我的 cmd 中正确记录的数据

现在我的路线代码是：

var express = require('express');
var router = express.Router();
var axios = require("axios");

/* GET home page. */
router.get('/', function(req, res, next) {
     axios.get('http://localhost:1337/restaurants')
       .then(response => ( res.render('index', { title: response.data}), console.log(response) ));
          });
    module.exports = router;

我的 PUG 文件只是试图使用变量 "title":

来显示 "reponse.data"

extends layout
block content

  //  response from the strapiapp api
  //  p  restaurant name is : #{title}
  p  Restaurant name is: #{title.name}

这是我的cmd的截图

这是典型的设置，我已经用不同的 api 做了很多次。如果我使用#{title}，我的浏览器会呈现[object Object]，如果我使用#{title.name}，它什么也不会显示。但数据已正确记录到我的 cmd。

如何在浏览器中显示对象？ title.name 和 titel.description 不工作，但数据已记录在我的 cmd express 中正确记录数据对象。

知道为什么它不显示对象属性吗？

Answer 1

正如亚历山大所说 response.data 是一个数组。所以你可以循环这个数组来显示所有数据。我以前没有用过哈巴狗，但我认为这应该有用。

ul
  each val in title
    li= val.name
