详解VueJs前后端分离跨域问题

使用vue-cli搭建的vue项目

可以使用在项目内设置代理（proxyTable）的方式来解决跨域问题

设置配置项的目录在config下的index.js，主要通过配置proxyTable项，设置代理指向你的后台地址

rush:plain;"> dev: { env: require('./dev.env'),port: 8085,autoOpenbrowser: true,assetssubdirectory: 'static',assetsPublicPath: '/',proxyTable: { '/agent': { target: 'http://127.0.0.1:7105/',changeOrigin: true,pathRewrite: { '^/agent': '' } } },// CSS Sourcemaps off by default because relative paths are "buggy" // with this option,according to the css-Loader README // (https://github.com/webpack/css-loader#sourcemaps) // In our experience,they generally work as expected,// just be aware of this issue when enabling this option. cssSourceMap: false }

前端使用vue-resource来发起请求时

rush:js;"> //在main.js中设置公用的地址 Vue.prototype.rootUrl = '/agent/';

//在具体page中发起请求的方式
that.$http.post(this.rootUrl + 'login',parms).then(function (response) {
// 响应成功回调
console.log(response);
},function (response) {
// 响应错误回调
});

其他方式搭建的前端项目，通过使用Nginx启动前端服务同时配置代理

下列是我的Nginx配置文件，不管是通过什么方式搭建的前端项目，构建成功后都会输出一个dist文件，我们只需要将Nginx服务目录指向你的dist文件下你项目的入口文件即可

我的文件目录是 root D:\openplatform\portal\webapp\dist; 更改此条配置到你的目录 我入口文件名称是index.html 使用的是vue-cli打包的项目，参考vue-cli npm run build的dist目录，指向那个目录下

rush:bash;"> #user nobody; worker_processes 4;

error_log logs/error.log;

error_log logs/error.log notice;

error_log logs/error.log info;

pid logs/Nginx.pid;

events {
worker_connections 1024;
}

http {
include mime.types;
default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" "$status" $body_bytes_sent "$http_referer" "$http_user_agent" "$http_x_forwarded_for" "$gzip_ratio" $request_time $bytes_sent $request_length';

log_format main '[$time_iso8601] [$remote_addr] [$request] [$http_user_agent] [$cookie_customerID_cookie_flag] [$args]';

access_log logs/access.log main;

sendfile on;

tcp_nopush on;

keepalive_timeout 0;

keepalive_timeout 65;

gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 3;
gzip_proxied any;
gzip_types *;

server {
listen 80;
root D:\openplatform\portal\webapp\dist;
index index.html;

location / {
   try_files $uri $uri/ @router;
   index index.html;
  }

location @router {
rewrite ^.*$ /index.html last;
}
location ^~/agent/ {
proxy_pass http://127.0.0.1:7105/;
proxy_redirect http://127.0.0.1:7105/ /;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_connect_timeout 600s;
proxy_read_timeout 600s;
proxy_send_timeout 600s;
}
}

another virtual host using mix of IP-,name-,and port-based configuration

server {

listen 8000;

listen somename:8080;

server_name somename alias another.alias;

location / {

root html;

index index.html index.htm;

}

}

HTTPS server

server {

listen 443 ssl;

server_name localhost;

ssl_certificate cert.pem;

ssl_certificate_key cert.key;

ssl_session_cache shared:SSL:1m;

ssl_session_timeout 5m;

ssl_ciphers HIGH:!aNULL:!MD5;

ssl_prefer_server_ciphers on;

location / {

root html;

index index.html index.htm;

}

}

}
