Django/Vue 应用程序中静态资产的 404 错误

Question

我试图关注 this article 将 Django/Vue 应用程序部署到 heroku。概述的步骤是：

• 运行 npm build 以创建包含已构建文件的 /dist 目录
• 到 settings.py 的 TEMPLATES = [...] 部分，添加 'DIRS':[os.path.join(BASE_DIR, 'dist')],
• 添加STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'dist/static')],（也在settings.py中）
• 编辑 django urls.py 文件以包含以下行：url(r'^$', TemplateView.as_view(template_name='index.html')),

此时我已经完成了所有这些事情，这是我清理过的 settings.py 文件：

"""

我查看了一些看似相关的问题（有些问题比其他问题更相关），但尝试这两个答案中的具体解决方案并没有解决问题： Error 404 static files in django 2.0

感谢任何帮助，如果有帮助，repo 是here.

Answer 1

正如我在github 的实现中看到的那样，您需要像这样在项目中定义资产目录（从代码中复制粘贴）：

module.exports = {
    outputDir: 'dist',
    assetsDir: 'static',
    // baseUrl: IS_PRODUCTION
    // ? 'http://cdn123.com'
    // : '/',
    // For Production, replace set baseUrl to CDN
    // And set the CDN origin to `yourdomain.com/static`
    // Whitenoise will serve once to CDN which will then cache
    // and distribute
    devServer: {
      proxy: {
        '/api*': {
          // Forward frontend dev server request for /api to django dev server
          target: 'http://localhost:8000/',
        }
      }
    }
}

基本上这里发生的情况是，您的静态文件在根路径/ 中提供服务，但静态文件应在路径/static 中提供（即：<your server>/static/js/abc.js）
