Detailed introduction to inter-service communication RPC
This article brings you a detailed introduction to RPC communication between services. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
Microservices are now prevalent, and there are probably two ways to communicate between services: Api and Rpc.
The following two examples will let you understand the difference between Api and Rpc.
Lie Zi 1 Addition, deletion, modification and review of articles.
Api implementation:
Router::get('/article/{id}','ArticleController@get'); Router::post('/article','ArticleController@create'); Router::put('/article/{id}','ArticleController@edit'); Router::delete('/article/{id}','ArticleController@delete');
Then call the model in the controller Article
return Article::find($id)->toArray();
Rpc implementation
RpcServer::add('Article');
Yes, just one line of code
Liezi 2 calculator
If there is a calculator on machine A Counter is provided to other machines in the form of Rpc.
Calculator Counter code
class Counter { private $i = 0; public function __construct($i = 0) { $this->i = $i; } // 加法 public function add($v) { $this->i += $v; return $this; } // 减法 public function sub($v) { $this->i -= $v; return $this; } // 乘法 public function mul($v) { $this->i *= $v; return $this; } // 除法 public function p($v) { $this->i /= $v; return $this; } // 获取结果 public function get() { return $this->i; } }
Rpc implementation
RpcServer::add('Counter');
Rpc client call
$c = new ClientCounter(10); echo $c->add(3)->mul(2)->sub(10)->p(5)->get();

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Managing concurrent session access in PHP can be done by the following methods: 1. Use the database to store session data, 2. Use Redis or Memcached, 3. Implement a session locking strategy. These methods help ensure data consistency and improve concurrency performance.

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.
