一段万能的nginx接口反向代理配置

nginx javascript

作为前端开发，每次调试接口，把代码发到测试服务器，是很费时费事的一件事情。
为了提高效率，想到了nginx反向代理来解决这一问题。

接口地址：
test.com

访问地址：
localhost

最核心的问题就是，登录时，无法写入cookie的问题，为了解决这个问题，走了不少弯路。

worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 10; server { listen 80; server_name localhost; location =/ { add_header X-Frame-Options SAMEORIGIN; root D:/workspace/; index index.html; } location ~* \.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css|swf|woff|woff2|ttf|json|svg|cur|vue|otf|eot)$ { charset utf-8; root D:/workspace/; expires 3d; } location = /socket/v2 { proxy_pass http://test.com; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host test.com; 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 30; proxy_send_timeout 30; proxy_read_timeout 60; proxy_buffer_size 256k; proxy_buffers 4 256k; } location / { proxy_pass http://test.com; proxy_set_header Cookie $http_cookie; proxy_cookie_domain test.com localhost; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host test.com; proxy_set_header X-Real-IP $remote_addr; proxy_set_header REMOTE-HOST $remote_addr; } } }

核心代码在三行代码上：
proxy_set_header Cookie $http_cookie;
proxy_cookie_domain test.com localhost;
proxy_set_header Host test.com;

具体解释我也是一知半解：
第一个是携带cookie，
第二个设置cookie 的 domain
第三个 设置真实的host

重要提示：以上3个的顺序不要颠倒，否则代理失败，我也不知道为什么。

如何在手机上调试呢？

手机上不可能直接访问localhost,可以把手机和电脑连接到同一个网段，使用电脑的ip进行访问。
但是这里只代理了localhost,并没有代理电脑的ip

所以，需要把是上面的server{...}拷贝一份，只需要把里面的localhost全部改成你的电脑ip就可以了，最终代码：

worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 10; server { listen 80; server_name localhost; location =/ { add_header X-Frame-Options SAMEORIGIN; root D:/workspace/; index index.html; } location ~* \.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css|swf|woff|woff2|ttf|json|svg|cur|vue|otf|eot)$ { charset utf-8; root D:/workspace/; expires 3d; } location = /socket/v2 { proxy_pass http://test.com; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host test.com; 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 30; proxy_send_timeout 30; proxy_read_timeout 60; proxy_buffer_size 256k; proxy_buffers 4 256k; } location / { proxy_pass http://test.com; proxy_set_header Cookie $http_cookie; proxy_cookie_domain test.com localhost; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host test.com; proxy_set_header X-Real-IP $remote_addr; proxy_set_header REMOTE-HOST $remote_addr; } } server { listen 8080; server_name xx.xx.xx.xx; location =/ { add_header X-Frame-Options SAMEORIGIN; root D:/workspace/; index index.html; } location ~* \.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css|swf|woff|woff2|ttf|json|svg|cur|vue|otf|eot)$ { charset utf-8; root D:/workspace/; expires 3d; } location = /socket/v2 { proxy_pass http://test.com; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host test.com; 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 30; proxy_send_timeout 30; proxy_read_timeout 60; proxy_buffer_size 256k; proxy_buffers 4 256k; } location / { proxy_pass http://test.com; proxy_set_header Cookie $http_cookie; proxy_cookie_domain test.com xx.xx.xx.xx; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host test.com; proxy_set_header X-Real-IP $remote_addr; proxy_set_header REMOTE-HOST $remote_addr; } } }

访问方法：

http://xx.xx.xx.xx:8080 即可

如果是打包工具生成增这个配置的话，可以用nodejs动态获取你电脑的ip

function  getIPAdress() {       var  interfaces  =  require('os').networkInterfaces();       for (var  devName  in  interfaces) {             var  iface  =  interfaces[devName];             for (var  i = 0; i < iface.length; i++) {                  var  alias  =  iface[i];                  if (alias.family  ===  'IPv4'  &&  alias.address  !==  '127.0.0.1'  &&  !alias.internal) {                        return  alias.address; }             }       }   }

所以，这里贴出来一个动态生成nginx.config的工具

function buildNginxConfig(config) { function  getIPAdress() {       var  interfaces  =  require('os').networkInterfaces();       for (var  devName  in  interfaces) {             var  iface  =  interfaces[devName];             for (var  i = 0; i < iface.length; i++) {                  var  alias  =  iface[i];                  if (alias.family  ===  'IPv4'  &&  alias.address  !==  '127.0.0.1'  &&  !alias.internal) {                        return  alias.address;                  }             }       }   } var cwd = process.cwd().replace(/\\/g, '/') + '/app'; var protocol = /https|443/.test(config.ip) ? 'https' : 'http'; var servers = [{ browserIp: 'localhost', port: 80, root: cwd, serverIp: config.ip, protocol: protocol, }, { browserIp: getIPAdress(), port: 8080, root: cwd, serverIp: config.ip, protocol: protocol, }].map(function(item) { return ` server { listen ${item.port}; server_name ${item.browserIp}; location =/ { add_header X-Frame-Options SAMEORIGIN; root ${item.root}; index index.html; } location ~* \\.(html|htm|gif|jpg|jpeg|bmp|png|ico|txt|js|css|swf|woff|woff2|ttf|json|svg|cur|vue|otf|eot)$ { charset utf-8; root ${item.root}; expires 3d; } location = /socket/v2 { proxy_pass ${item.protocol}://${item.serverIp}; proxy_redirect off; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host ${item.serverIp}; 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 30; proxy_send_timeout 30; proxy_read_timeout 60; proxy_buffer_size 256k; proxy_buffers 4 256k; } location / { proxy_pass ${item.protocol}://${item.serverIp}; proxy_set_header Cookie $http_cookie; proxy_cookie_domain ${item.serverIp} ${item.browserIp}; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host ${item.serverIp}; proxy_set_header X-Real-IP $remote_addr; proxy_set_header REMOTE-HOST $remote_addr; } }`; }).join('\n'); var str = `worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 10; ${servers} }`; return str; } exports = module.exports = buildNginxConfig;

有了这个万能反向代理，可以随心所欲的玩转任何网站接口了
