javascript - 尝试加载 mapbox 时收到错误消息

问题描述

mapboxgl.accessToken = 'xxxxxxxx';

var map = new mapboxgl.Map({
  container: 'map', // container ID
  style: 'mapbox://styles/mapbox/streets-v11', // style URL
});
doctype html
html
  head
    block head
      meta(charset='UTF-8') 
      meta(name='viewport' content='width=device-width, initial-scale=1.0')
      link(rel='stylesheet' href='/css/style.css')
      link(rel='shortcut icon', type='/image/png' href='/ img/favicon.png')
      link(rel='stylesheet', href='https://fonts. googleapis.com/css?family=Lato:300,300i,700')
      title Natours | #{title} 


  body
      //- HEADER 
      include _header

      //- CONTENT
      block content
        h1 this is a placeholder heading

      //- FOOTER
      include _footer
      
      script(src='/javascript/mapbox.js')

拒绝加载脚本“https://api.mapbox.com/mapbox-gl-js/v2.1.1/mapbox-gl.js”，因为它违反了以下内容安全策略指令：“script-src 'self'” . 请注意，'script-src-elem' 没有明确设置，因此 'script-src' 用作后备。

解决方案

我今天碰到了这个问题。我知道你现在可能已经得到答复了。但下面仍然是你的答案：学分东林-

发送 CSP 标头以允许加载来自 mapbox 的脚本。下面的示例：

exports.getTour = catchAsync(async (req, res, next) => {
  const tour = await Tour.findOne({ slug: req.params.slug }).populate({
    path: 'reviews',
    fields: 'review rating user'
  });
  res
    .status(200)
    .set(
      'Content-Security-Policy',
      "default-src 'self' https://*.mapbox.com ;base-uri 'self';block-all-mixed-content;font-src 'self' https: data:;frame-ancestors 'self';img-src 'self' data:;object-src 'none';script-src https://cdnjs.cloudflare.com https://api.mapbox.com 'self' blob: ;script-src-attr 'none';style-src 'self' https: 'unsafe-inline';upgrade-insecure-requests;"
    )
    .render('tour', {
      title: `${tour.title} Tour`,
      tour
    });
});
