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

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

//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

#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

 # ssl_certificate cert.pem;
 # ssl_certificate_key cert.key;

 # ssl_session_cache shared:SSL:1m;

 # ssl_ciphers HIGH:!aNULL:!MD5;
