Javascript 如何使用 API 检索数据

Question

我想连接到 API 并从中检索数据。我需要在 Hubspot CMS 上完成。

这是 API 的链接：
https://staging.tabsera.com/apiDoc/#api-landing-getCourses

我尝试使用 Codepen 示例执行此操作，但即使控制台没有显示任何错误，它也没有显示数据：

const courses = document.getElementById('courses'),
url = 'https://staging.tabsera.com/api/v1/landing/courses';

const createNode = element => {return document.createElement(element);};
const append = (parent, el) => {return parent.appendChild(el);};

fetch(url).
then(response => {return response.json();}).
then(data => {
  let courses = data.results;
  return courses.map(courses => {
    let english = createNode('<div class="english">'),
    img = createNode('img'),
    span = createNode('span');
    img.src = runner.picture.medium;
    span.innerHTML = `${courses.english.author} ${courses.name.last}`;
    append(div, img);
    append(div, span);
    append(div, div);
  });
}).
catch(error => {console.log(error);});

非常感谢任何帮助。

Answer 1

您的回复中没有results 字段，请直接尝试courses：

fetch('https://staging.tabsera.com/api/v1/landing/courses')
  .then(response => response.json())
  .then(data => console.log(data.courses))

Answer 2

我用过axios； 我得到了你需要的东西。这是一个简单的方法。

var axios = require('axios');
var qs = require("querystring");

axios("https://staging.tabsera.com/api/v1/landing/courses", {
    method: "GET"
})
    .then(response => {
        console.log("Application data");
        console.log(response.data.courses.English);
    })
    .catch(err => {
        console.log("**************Get access token error**************")
        console.log(err)
    });

Answer 3

您可以在 let courses = data.results; 行之前添加日志行 console.log(data)

在那里，您可以在浏览器的控制台窗口（如下所示）中看到数据对象包含课程属性而不是结果。 courses: Arabic: []English: [{…}]Maths: []Science: [{…}]Social: []

所以你可以将课程的阅读发送到let courses = data.courses;

Answer 4

请试一试。

const ul = document.getElementById('runners'),
url = 'https://staging.tabsera.com/api/v1/landing/courses';

const createNode = element => {return document.createElement(element);};
const append = (parent, el) => {return parent.appendChild(el);};

fetch(url).
then(response => {return response.json();}).
then(data => {
  let courses = data.courses;
  for (course in courses) {
    runners = courses[course];
    runners.map(runner => {
      let li = createNode('li'),
      span = createNode('span');
      span.innerHTML = `${runner.author}`;
      append(li, span);
      append(ul, li);
    });
  }
  
}).
catch(error => {console.log(error);});
