跨域请求错误(CORS error)是指在前后端分离项目中,由于跨域请求失败而引发的错误。跨域请求是指在浏览器中,通过JavaScript代码向不同域名或端口发送请求。解决CORS错误的方法有多种。一种方法是通过配置类重写addCorsMappings方法来设置允许跨域请求的路径、域名、方法、header属性和跨域时间等参数。另一种方法是在controller中添加@CrossOrigin注解来允许跨域请求。还可以使用nginx来解决跨域请求问题。具体的解决方法可以根据项目的需求和实际情况选择。\[1\]\[2\]\[3\]

CORS error
CORS error指的是跨域资源共享错误。当在前后端分离的项目中进行跨域请求时,有可能会出现CORS error。解决CORS error的方法有以下几种:
1. 配置类重写addCorsMappings方法:可以创建一个配置类,重写addCorsMappings方法,并在该方法中设置允许跨域请求的路径、域名、方法、header属性以及跨域时间等参数来解决CORS error。
2. Controller添加@CrossOrigin注解:可以在Controller类或方法上添加@CrossOrigin注解,来允许指定的域名进行跨域请求,从而解决CORS error。
3. 使用nginx解决跨域请求:可以通过配置nginx服务器来解决CORS error。在nginx的配置文件中添加相关配置,允许指定的域名进行跨域请求。
需要注意的是,具体选择哪种解决方法,取决于项目的具体情况和需求。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

cors error php
CORS (Cross-Origin Resource Sharing) error occurs when a web page running on one domain tries to access resources from another domain. This error typically occurs when making AJAX requests from a web page hosted on one domain to a PHP script hosted on another domain.
To resolve the CORS error in PHP, you can add the following code to your PHP script:
```
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS");
header("Access-Control-Allow-Headers: Content-Type, Authorization, X-Requested-With");
```
This code adds the necessary CORS headers to the response, allowing the web page to access the resources from the PHP script. Additionally, you can also configure your web server to allow CORS by adding the necessary headers to the response using the .htaccess file.
