发送CSP标头以允许从Mapbox加载脚本。示例如下：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
});
});
