What is Nginx proxy service? Examples of nginx forward proxy and reverse proxy
This article introduces to you what is Nginx proxy service? The examples of nginx forward proxy and reverse proxy have certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
1. Agent introduction
1. Agent
The object of the forward proxy is the client
The object of the reverse proxy proxy is the server
4. Nginx proxy module ngx_http_proxy_module
SyntaxSyntax: proxy_pass URL;
Default: —
Context: location, if in location, limit_except
Copy after login
URL support:
Syntax: proxy_pass URL; Default: — Context: location, if in location, limit_except
- http：
http: //localhost:8000/uri/
- https：
https://192.168.1.111:8000/uri/
- socket:
http://unix:/tmp/backend.socket:/uri/
1. Create the real service configuration to be accessed: vim conf.d/real_server.confserver {
# 监听8080端口
listen 8080;
location / {
# 配置访问根目录为 /vagrant/proxy
root /vagrant/proxy;
}
}Copy after login
server {
# 监听8080端口
listen 8080;
location / {
# 配置访问根目录为 /vagrant/proxy
root /vagrant/proxy;
}
}2. Create the reverse proxy configuration vim conf.d/fx_proxy.confserver {
# 监听80端口
listen 80;
server_name localhost;
location ~ /fx_proxy.html {
# 设置反向代理，将访问 /fx_proxy.html 的请求转发到 http://127.0.0.1:8080
proxy_pass http://127.0.0.1:8080;
}
}Copy after login
server {
# 监听80端口
listen 80;
server_name localhost;
location ~ /fx_proxy.html {
# 设置反向代理，将访问 /fx_proxy.html 的请求转发到 http://127.0.0.1:8080
proxy_pass http://127.0.0.1:8080;
}
}3. nginx -s reload Reload nginx configuration file
4. Create /vagrant/proxy/fx_proxy.html file
- vim /vagrant/proxy/fx_proxy.html
nbsp;html> <meta> <title>反向代理</title> <h1 id="反向代理">反向代理</h1>
5. Use ss -tln to check whether port 80 and port 8080 are all open[root~]# ss -tln
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:8080 *:*
LISTEN 0 128 *:80 *:*
LISTEN 0 128 *:22 *:*
LISTEN 0 10 127.0.0.1:25 *:*
LISTEN 0 128 :::22 :::*
Copy after login
[root~]# ss -tln State Recv-Q Send-Q Local Address:Port Peer Address:Port LISTEN 0 128 *:8080 *:* LISTEN 0 128 *:80 *:* LISTEN 0 128 *:22 *:* LISTEN 0 10 127.0.0.1:25 *:* LISTEN 0 128 :::22 :::*
6. Use curl for access testing
http://127.0.0.1/fx_proxy.html
can be accessed normally
[root~]# curl http://127.0.0.1/fx_proxy.html nbsp;html> <meta> <title>反向代理</title> <h1 id="反向代理">反向代理</h1>
http://127.0.0.1:8080/fx_proxy.html
can be accessed normally
[root~]# curl http://127.0.0.1:8080/fx_proxy.html nbsp;html> <meta> <title>反向代理</title> <h1 id="反向代理">反向代理</h1>
The IP address of the author's remote server is: 39.106.178.166, and the domain name used for testing is zx_proxy.ws65535.top
1. 在服务器创建真实要访问的服务配置：vim conf.d/real_server.conf
server {
# 监听80端口
listen 80;
# 域名为 zx_proxy.ws65535.top;
server_name zx_proxy.ws65535.top;
location / {
# $http_x_forwarded_for 可以记录客户端及所有中间代理的IP
# 判断客户端IP地址是否是 39.106.178.166，不是则返回403
if ($http_x_forwarded_for !~* "^39\.106\.178\.166") {
return 403;
}
root /usr/share/nginx/html;
index index.html;
}
}2. nginx -s reload 重新载入nginx配置文件
3. 在本地使用浏览器访问 http://zx_proxy.ws65535.top/，返回 403 Forbidden，说明访问被拒绝
4. 在服务器创建代理服务配置：vim conf.d/zx_proxy.conf
server {
# 代理服务监听的端口（注意，一定要看服务器供应商控制台的安全组是否开启了该端口）
listen 3389;
# 配置DNS，223.5.5.5是阿里云的DNS
resolver 223.5.5.5;
# 正向代理配置
location / {
proxy_pass http://$http_host$request_uri;
}
}5. nginx -s reload 重新载入nginx配置文件
6. 浏览器配置代理（以下是Windows10的代理配置方式，其他操作系统自行配置）
控制面板 -> 网络和Internet -> 代理 -> 手动设置代理
7. 设置代理后在本地使用浏览器访问 http://zx_proxy.ws65535.top/，可以正常访问

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Apr 03, 2025 am 12:04 AM
Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
