基础 url 不会根据 link 改变

Question

我有一个硬编码的 JSON 数据，在应用程序执行时显示，我使用 JSON-schema-faker 获取一些 mockApi 数据并在我设置查询参数 useMockApi 时显示它真实的我希望 link 根据环境进行更改，但是当我将 useMockApi 设置为 true 时，它会给我这个错误

import { getUsers, deleteUser } from "./api/userApi.js";



getUsers().then(result => {
    let userBody = "";

    result.forEach(user => {
        userBody += `<tr>       
        <td><a href="#" id="${user.id}"  class="del">Delete </a></td>
        <td>${user.id}</td>
        <td>${user.firstName}</td>
        <td>${user.lastName}</td>
        <td>${user.email}</td>
        </tr>`
    });
    global.document.getElementById('users').innerHTML = userBody;

    const deleteLinks = document.querySelectorAll('.del');

    Array.from(deleteLinks, link => {
        link.onclick = (event) => {
            const element = event.currentTarget;
            event.preventDefault();

            deleteUser(element.id) //eslint-disable-line no-console
            const row = element.parentNode.parentNode;
            row.remove();
        }
    })

})

无法在 'Window' 上执行 'fetch'：无法从 http://localhost:5000users

解析 URL

这是我的代码

/* eslint-disable no-unused-vars */
import "whatwg-fetch";

import getBaseUrl from './baseUrl';

const baseurl = getBaseUrl();

export function getUsers() {
    return get('users');
}

export function deleteUser(id) {
    return del(`users/${id}`)
}

function get(url) {
    return fetch(baseurl + url).then(onSuccess, onError);
}

function del(url) {
    const request = new Request(`${baseurl}/${url}`, {
        method: 'DELETE'
    });
    return fetch(request).then(onSuccess, onError)

}

function onSuccess(response) {
    return response.json();
}

function onError(err) {
    console.log(err); //eslint-disable-line no-console
}

export default function getBaseUrl() {
    return getQueryStringParameterByName('useMockApi') ? 'http://localhost:5000' : '/';
}


function getQueryStringParameterByName(name, url) {
    if (!url) {
        url = window.location.href;
    }


    name = name.replace(/[\[\]]/g, "\$&")
    var regex = new RegExp(`[?&]${name}(=([^&#]*)|&|#|$)`),
        results = regex.exec(url);
    if (!results) return null;
    if (!results[2]) return '';

    return decodeURIComponent(results[2].replace(/\+/g, " "))
}

Answer 1

尝试在 localhost:5000

后添加正斜杠

return getQueryStringParameterByName('useMockApi') ? 'http://localhost:5000/' : '/';

基础 url 不会根据 link 改变

Base url doesn't change based on the link
