1、spring boot跨域配置有两种方法
在后端使用spring boot。spring boot跨域非常简单,只需书写以下代码即可。

@configuration public class customcorsconfiguration { private corsconfiguration buildconfig() { corsconfiguration corsconfiguration = new corsconfiguration(); corsconfiguration.addallowedorigin( "*" ); corsconfiguration.addallowedheader( "*" ); corsconfiguration.addallowedmethod( "*" ); corsconfiguration.setallowcredentials( true ); return corsconfiguration; } @bean public corsfilter corsfilter() { urlbasedcorsconfigurationsource source = new urlbasedcorsconfigurationsource(); source.registercorsconfiguration( "/**" , buildconfig()); return new corsfilter(source); } } |
2.nginx跨域配置
spring boot应用用nginx反向代理。而前端跨域请求的需求不减。
nginx跨域也比较简单,只需添加以下配置即可。

location / { proxy_pass http: //localhost:8080; if ($request_method = 'options' ) { add_header 'access-control-allow-origin' '*' ; add_header 'access-control-allow-methods' 'get, post, options' ; add_header 'access-control-allow-headers' 'dnt,x-customheader,keep-alive,user-agent,x-requested-with,if-modified-since,cache-control,content-type,content-range,range,token' ; add_header 'access-control-max-age' 1728000 ; add_header 'content-type' 'text/plain; charset=utf-8' ; add_header 'content-length' 0 ; return 204 ; } if ($request_method = 'post' ) { add_header 'access-control-allow-origin' '*' ; add_header 'access-control-allow-methods' 'get, post, options' ; add_header 'access-control-allow-headers' 'dnt,x-customheader,keep-alive,user-agent,x-requested-with,if-modified-since,cache-control,content-type,content-range,range,token' ; add_header 'access-control-expose-headers' 'dnt,x-customheader,keep-alive,user-agent,x-requested-with,if-modified-since,cache-control,content-type,content-range,range,token' ; } if ($request_method = 'get' ) { add_header 'access-control-allow-origin' '*' ; add_header 'access-control-allow-methods' 'get, post, options' ; add_header 'access-control-allow-headers' 'dnt,x-customheader,keep-alive,user-agent,x-requested-with,if-modified-since,cache-control,content-type,content-range,range,token' ; add_header 'access-control-expose-headers' 'dnt,x-customheader,keep-alive,user-agent,x-requested-with,if-modified-since,cache-control,content-type,content-range,range,token' ; } } |
其中:add_header 'access-control-expose-headers' 务必加上你请求时所带的header。
例如本例中的“token”,其实是前端传给后端过来的。如果记不得也没有关系,浏览器的调试器会有详细说明。
三、浏览器设置跨域
chrome、firefox本身是可以通过配置支持跨域请求的。
chrome跨域:参考文档:chrome跨域
四、前端vue设置跨域
先设置 axios

axios.defaults.withcredentials = true ; axios.defaults.headers.common[ 'x-requested-with' ] = 'xmlhttprequest' ; //证明是ajax 请求 psot 请求加入 headers: { 'content-type' : 'application/x-www-form-urlencoded; charset=utf-8' , } |
设置config 文件下面的index.js 然后就可以再其它页面访问了
