node.js - Axios 只为程序中的一个函数返回 HTML 而不是 JSON

问题描述

我正在使用跟踪学生的 MEVN 堆栈构建一个小型 CRUD 应用程序。响应以 HTML 格式而不是 JSON 格式输出：

蒙哥模型

var StudentSchema = new mongoose.Schema({
  first: String,
  last: String,
  teacher: String,
  classroom: String,
  major: String,
  minor: String,
  updated_date: { type: Date, default: Date.now },
});

高速路由器

router.get('/', function(req, res, next) {
  Book.find(function (err, products) {
    if (err) return next(err);
    res.json(products);
  });
});

学生名单组件

created () {
    axios.get(`/student`)
    .then(response => {
      console.log(response.data);
      this.students = response.data
    })
    .catch(e => {
      this.errors.push(e)
    })
  },

每次我调用“学生”路由来获取所有学生的列表时，我都会reponse.data以 HTML 而不是 JSON 的形式返回。

返回的数据 (HTML)

<title>mevn-stack</title>
<script type=text/javascript src=/static/js/manifest.d39e40457f281fdf3544.js></script>
<script type=text/javascript src=/static/js/vendor.a0442dcc64c824d931ee.js></script>
<script type=text/javascript src=/static/js/app.b0051853730faf43e49b.js></script>

控制台错误

s.foreach 不是函数

更新

这是@JoelHager 推荐的对学生列表组件中的响应进行字符串化的输出

{
  "data": "<!DOCTYPE html><html><head><meta charset=utf-8><meta name=viewport content=\"width=device-width,initial-scale=1\"><title>mevn-stack</title><link href=/static/css/app.ae61a91c1a891593d309fd6551053eab.css rel=stylesheet></head><body><div id=app></div><script type=text/javascript src=/static/js/manifest.a9cf3b120af2eaf30b2a.js></script><script type=text/javascript src=/static/js/vendor.7f820bcda7e516bfce3e.js></script><script type=text/javascript src=/static/js/app.a88ae44d36b2723e3a14.js></script></body></html>",

}
