我试图运行一个LaravelV8.14(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)都会在我的本地计算机上使用WAMP获取CORS策略错误。
运行npm run dev,一切都会被编译,并开始侦听http://localhost:3000/。当我试图访问我的homepage.but时,控制台或命令提示符上没有错误,api请求得到CORS策略错误。我尝试过baseURL和nuxtJS代理,但是错误始终保持不变,我知道您不能同时使用这两个

No 'Access-Control-Allow-Origin' header is present on the requested resource.所有API请求都在路由文件夹的laravel api.php中。
我被困在这里面已经5天了,而且大多数时候我都在用代理来改变东西,希望它能起作用,time.even做了一个全新的nuxtJS安装(删除了node_modules和package.json.lock),但是没有任何进展。
任何帮助都将不胜感激。

问题是我的wamp apache配置,我将解释我采取的步骤,以找出是什么导致CORS错误,以及我如何修复它。
在一个新的窗口上安装了所有东西之后,我仍然面临着这个问题,但在一个活动服务器上的不是,所以我认为它一定是我正在运行的web服务器,而这是我在WAMP上的apache配置中issue.The错误的部分:
DocumentRoot "${INSTALL_DIR}/www/laravel/"
<Directory "${INSTALL_DIR}/www/laravel/">我在httpd-vhosts.conf.After和httpd.conf中都将上面的内容更改为(添加了laravel的公用文件夹):
DocumentRoot "${INSTALL_DIR}/www/laravel/public"
<Directory "${INSTALL_DIR}/www/laravel/public">在我发布的问题中,一切都开始与相同的配置一起工作,CORS策略错误消失了。
我还测试了另一种方法,您可以删除代理,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, */*',
}
},如果CLIENT_URL是一个.env laravel文件变量,在我的例子中它的值是http://localhost,那么任何与代理相关的内容都应该被注释,因为不能同时使用代理和baseURL。
了解有关nuxt axios模块这里的更多信息
请记住,在您的LoadModule headers_module modules/mod_headers.so中,您的httpd.conf中也必须有未注释的headers_module。
谢谢你一路来的帮助

您可以检查是否有像die(...)、dd(..)或exit这样的异常响应。这些方法也可能触发cors错误。
