这篇文章主要介绍了springboot vue 跨域问题的解决,小编觉得挺不错的,现在分享给大家,也给大家做个参考。一起跟随小编过来看看吧
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 axiosaxios.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
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持CodeAE代码之家。
