使用PHP的soap扩展, 进行wdsl操作
本文是一个使用php soap访问webservice的例子. wsdl文件请见http://www.webxml.com.cn/这个网站. 里面有很多好用的服务器. 大部分可以免费使用, 有一部分要收费. 以中文简繁转换为例. 简繁转换的wsdl文件地址为:http://webservice.webxml.com.cn/WebServices
本文是一个使用php soap访问webservice的例子.
wsdl文件请见http://www.webxml.com.cn/ 这个网站. 里面有很多好用的服务器.
大部分可以免费使用, 有一部分要收费.
以中文简繁转换为例.
简繁转换的wsdl文件地址为: http://webservice.webxml.com.cn/WebServices/TraditionalSimplifiedWebService.asmx?wsdl
下面是PHP代码, 其中有说明.
<?php $wsdl = 'http://webservice.webxml.com.cn/WebServices/TraditionalSimplifiedWebService.asmx?wsdl'; // 以wsdl方式, 实例化类. $soap = new SoapClient( $wsdl ); var_dump ( $soap->__getFunctions() ); // 这是此接口可以提供哪些服务, 就是函数定义, 有参数, 有返回值 var_dump( $soap->__getTypes() ); // 这是此接口使用的数据类型.
以下为上面例子的返回值:
函数声明
<strong>array</strong> <em>(size=4)</em> 0 <span>=></span> <small>string</small> <span>'toSimplifiedChineseResponse toSimplifiedChinese(toSimplifiedChinese $parameters)'</span> <em>(length=80)</em> 1 <span>=></span> <small>string</small> <span>'toTraditionalChineseResponse toTraditionalChinese(toTraditionalChinese $parameters)'</span> <em>(length=83)</em> 2 <span>=></span> <small>string</small> <span>'toSimplifiedChineseResponse toSimplifiedChinese(toSimplifiedChinese $parameters)'</span> <em>(length=80)</em> 3 <span>=></span> <small>string</small> <span>'toTraditionalChineseResponse toTraditionalChinese(toTraditionalChinese $parameters)'</span> <em>(length=83)</em>
类型定义
<strong>array</strong> <em>(size=4)</em> 0 <span>=></span> <small>string</small> <span>'struct toSimplifiedChinese { string sText; }'</span> <em>(length=45)</em> 1 <span>=></span> <small>string</small> <span>'struct toSimplifiedChineseResponse { string toSimplifiedChineseResult; }'</span> <em>(length=73)</em> 2 <span>=></span> <small>string</small> <span>'struct toTraditionalChinese { string sText; }'</span> <em>(length=46)</em> 3 <span>=></span> <small>string</small> <span>'struct toTraditionalChineseResponse { string toTraditionalChineseResult; }'</span> <em>(length=75)</em>
从这个输出中, 可以看到,
<span>toTraditionalChineseResponse toTraditionalChinese(toTraditionalChinese $parameters)</span>
这是简体转换为繁体的函数.
参数 toTraditionalChinese
结构为:
<span>struct toTraditionalChinese { string sText; }</span>
对应 于PHP, 就是一个数组, 以sText为键, 值为字符串,
例如: array( 'sText' => '要转成繁体的汉字' )
此函数的返回值为:
<span>struct toTraditionalChineseResponse { string toTraditionalChineseResult; }</span>
这对于PHP就是, 一个stdClass, 有一个叫做toTraditionalChineseResult的属性
下面是一个有完整返回值的PHP代码, 其中包含发送的xml信息和接收的xml信息.
<?php // wsdl地址 $wsdl = 'http://webservice.webxml.com.cn/WebServices/TraditionalSimplifiedWebService.asmx?wsdl'; // 实例化, trace表示要记录发送接收的xml数据 $soap = new SoapClient( $wsdl, array( 'trace' => true) ); // 直接调用这个函数, 因为在此对象中, 所有的函数都是以双下划线开头, 所以不会有冲突. $rs = $soap->toTraditionalChinese( array( 'sText' => '我要转成繁体哦, 龙' )); // 显示转换以后的值, stdClass对象. var_dump( $rs ); // 显示转换的内容, 字符串 echo $rs->toTraditionalChineseResult; echo '<hr>以下为收发信息'; // 发送HTTP头 var_dump( $soap->__getLastRequestHeaders() ); // 发送的HTTP_BODY var_dump( $soap->__getLastRequest() ); // 接收的HTTP头 var_dump( $soap->__getLastResponseHeaders() ); // 接收的HTTP_BODY var_dump( $soap->__getLastResponse() );
以下是上面这个例子的返回值:
object(stdClass)[2]
public 'toTraditionalChineseResult' => string '我要轉成繁體哦, 龍' (length=26)
我要轉成繁體哦, 龍
以下为收发信息

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,

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.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
