我试图运行Laravel V8.14(后端(和nuxtJS 2.15(前端(应用程序，但不幸的是，每个API请求(包括SSR请求(都会在我的LOCAL计算机上使用WAMP 获取CORS策略错误
运行npm run dev，所有内容都被编译并开始侦听http://localhost:3000/。当我试图访问主页时，控制台或命令提示符上没有错误。但是api请求获取CORS策略错误。我尝试过使用nuxtJS的baseURL和proxy，但错误一直保持不变。我知道你不能同时拥有这两个

精确错误

所有API请求都在路由文件夹中的laravel-API.php中
我已经被困了5天了，大部分时间我都在用代理更换东西，希望下次能正常工作。我甚至全新安装了nuxtJS(删除了node_modules和package.json.lock(，但运气不佳。
如有任何帮助，我们将不胜感激。
您可以检查是否有任何异常响应，如die(...)、dd(..)或exit。这些方法也可能触发cors错误。
问题是我的wampapache配置，我将解释我采取的步骤，以找出导致CORS错误的原因以及我如何修复它。
在新窗口上安装完所有内容后，我仍然面临这个问题，但不是在实时服务器上，所以我认为它一定是我正在运行的web服务器，这就是问题所在。我在WAMP上的apache配置的错误部分是：
DocumentRoot "${INSTALL_DIR}/www/laravel/"
<Directory "${INSTALL_DIR}/www/laravel/">
我在httpd.conf和httpsvhosts.conf中都有。在将上述内容更改为(添加laravel的公用文件夹(后：
DocumentRoot "${INSTALL_DIR}/www/laravel/public"
<Directory "${INSTALL_DIR}/www/laravel/public">
在我发布的问题中，一切都开始使用SAME配置，CORS策略错误消失了。
我还测试了另一种方法，你可以删除代理，nuxt.config.js文件中的axios设置如下：
axios:{
baseURL : process.env.CLIENT_URL, //Cant be used with proxy
browserBaseURL: process.env.CLIENT_URL + '/api', // client url
common: {
'Content-Type': 'application/x-www-form-urlencoded',
'Accept': 'application/json, text/plain, */*',
}
},
其中CLIENT_URL是.env laravel文件变量，在我的情况下其值为http://localhost，任何与代理相关的内容都应该注释，因为不能同时使用代理和baseURL。

请记住，您也必须在httpd.conf 中取消注释LoadModule headers_module modules/mod_headers.so(也称为headers_module(
