Laravel 下使用 Guzzle 编写多线程爬虫实战
说明
Guzzle库是一套强大的 PHP HTTP 请求套件。
本文重点演示如何使用 Guzzle 发起多线程请求。
参考
- Github 官方用户接口文档
- Guzzle 并发请求文档
- Laravel LTS 5.1 - Artisan 文档
创建命令
1. 运行命令行创建命令

2. 注册命令
编辑 app/Console/Kernel.php,在 $commands 数组中增加:
1 |

3. 测试下命令
修改 app/Console/Commands/MultithreadingRequest.php文件,在 handle方法中增加:
1 |
|
输出:
1 |

直接贴代码
一份可运行的代码胜过千言万语呀。
下面代码是 app/Console/Commands/MultithreadingRequest.php里的内容:
1 |
|
运行结果:
1 |

注意请求是同时发送过去的,因为 concurrency并发设置了 7,所以 7 个请求同时发送,只不过接收到返回的时间点不一样。
完。

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.
