php模拟asp中的XmlHttpRequest实现http请求的代码_PHP
类名 :HttpRequest($url="",$method="GET",$useSocket=0)
//$url为请求的地址;默认请求方法为GET;$useSocket默认为0,使用fsockopen方法,如果设置为1则使用socket_create方法
方法:
open($ip="",$port=-1) //打开同服务器的连接,默认不用设置这两个参数(一个同事在linux用的时候,请求的不是hostname解析的IP,因此加了这两个参数,以连接真实的服务器IP)
setTimeout($timeout=0) //设置获取数据的超时时间,必须在send方法调用之前设置才有效,单位秒,默认值0为不限制
setRequestHeader($key,$value="") //设置请求头,必须在send方法调用之前设置才有效
removeRequestHeader($key,$value="") //移除指定键值的请求头,必须在send方法调用之前调用才有效
send($data="") //发送数据$data到服务器
getResponseBody() //获取服务器返回的文本
getAllResponseHeaders() //获取服务器响应的所有头信息
getResponseHeader($key) //获取服务器响应的某个头信息,例如Server,Set_Cookie等
属性:
$url //要请求的url
$method //请求方法(POST/GET)
$port //请求的端口
$hostname //请求的主机名
$uri //url的文件部分
$protocol //请求协议(http)(包括本属性的以上5个属性均由程序自动通过url分析)
$excption //异常信息
$_headers=array() //请求头array("key"=>"value")
$_senddata //发送到服务器的数据
$status //返回的状态码
$statusText //状态信息
$HttpProtocolVersion //服务器的HTTP协议版本
注意:
Host头由程序自动设置,当用POST方法请求时,Content-Length和Content-Type已被自动设置。
支持gzip压缩的页面

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,

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.

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.

Article discusses late static binding (LSB) in PHP, introduced in PHP 5.3, allowing runtime resolution of static method calls for more flexible inheritance.Main issue: LSB vs. traditional polymorphism; LSB's practical applications and potential perfo
