nginx interface reverse proxy configuration introduction

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(&#39;os&#39;).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  ===  &#39;IPv4&#39;  &&  alias.address  !==  &#39;127.0.0.1&#39;  &&  !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(&#39;os&#39;).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  ===  &#39;IPv4&#39;  &&  alias.address  !==  &#39;127.0.0.1&#39;  &&  !alias.internal) {                       
                    return  alias.address;                 
                }            
            }      
        }  
    }
    var cwd = process.cwd().replace(/\\/g, &#39;/&#39;) + &#39;/app&#39;;
    var protocol = /https|443/.test(config.ip) ? &#39;https&#39; : &#39;http&#39;;
    var servers = [{
        browserIp: &#39;localhost&#39;,
        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};

            root        ${item.root};

        }

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
