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 # #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; # } #}}
