服务器不能DELETE和PUT

问题描述：前端VUE、后端JAVA，代码放在本地可以完美运行，放在服务器外网不能运行delete和put，get和post不能运行
经过摸索总结，在不改变原有RESTful的情况下，亲身实验，得到两种解决办法：
一：改前端配置和nginx（后台是经过nginx代理）

前端http配置：

1.put和delete请求改为post请求
2.put请求添加请求头：X-Http-Method-Override: PUT；
delete请求添加请求头：X-Http-Method-Override: DELETE；

nginx配置：

在server里面添加如下代码

server {...set $method $request_method;if ($http_X_HTTP_Method_Override ~* 'PUT|DELETE') {set $method $http_X_HTTP_Method_Override;}proxy_method $method;...
}

重启nginx，完毕！

二：改前端配置和后端配置（后台不经过nginx，直接访问）

前端http配置：

1.put和delete请求改为post请求
2.put请求添加请求头：X-Http-Method-Override: PUT；
delete请求添加请求头：X-Http-Method-Override: DELETE；

后端http配置：

新建一个过滤器类 ChangeHttpMethodFilter

import org.springframework.core.annotation.Order;
import org.springframework.http.HttpMethod;
import org.springframework.stereotype.Component;import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import java.io.IOException;/*** 改变请求头的过滤器** @author xu* 2024/3/28 12:08*/
@Order(1)// 执行顺序最小
@Component
public class ChangeHttpMethodFilter implements Filter {@Overridepublic void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {HttpServletRequest httpServletRequest = (HttpServletRequest) servletRequest;String method = httpServletRequest.getHeader("X-Http-Method-Override");// 如果修改和删除需要改变if(HttpMethod.DELETE.name().equals(method) || HttpMethod.PUT.name().equals(method)){HttpServletRequestWrapper requestWrapper = new HttpServletRequestWrapper(httpServletRequest) {@Overridepublic String getMethod() {return method.toUpperCase();}};filterChain.doFilter(requestWrapper, servletResponse);}else {filterChain.doFilter(servletRequest, servletResponse);}}
}
