利用PHP SOAP扩展实现简单Web Services,soapservices

WebServices能干什么?

WebServices 可以将应用程序转换为网络应用程序。

通过使用 WebServices,您的应用程序可以向全世界发布信息,或提供某项功能。

 

好了,关于WebServices网上资料很多,就不过多介绍了,直接进入主题。

PHP有两个扩展类库可以实现WebServices,一个是NuSoap,一个是php官方自带的Soap扩展,在使用上大致都差不多,就拿官方自带的Soap扩展来说吧。

在Soap编写WebServices中主要用到了SoapClient,SoapServer,SoapFault三个类。

SoapClient:用户访问的类,也就是客户端,使用WebServices的类

SoapServer:提供WebServices类,服务端

SoapFault:异常处理类

 

作为示例,写个超级简单的的WebServices来感受下吧,直接代码说话

 

1、Myself.class.php  --业务逻辑类,功能实现类

<span>1</span> <?<span>php
</span><span>2</span>     <span>//</span><span>业务逻辑类</span>
<span>3</span>     <span>class</span><span> Myself{
</span><span>4</span>         <span>public</span> <span>function</span><span> info(){
</span><span>5</span>             <span>return</span> "新浪微博:Balla_兔子,求关注啦~"<span>;
</span><span>6</span> <span>        }
</span><span>7</span> <span>    }
</span><span>8</span> ?>
Copy after login

很简单,无需多余解释,返回一个字符串。

2、soapServer.php  --服务端类,提供服务

<span> 1</span> <?<span>php
</span><span> 2</span>     <span>//</span><span>服务端</span>
<span> 3</span>     <span>require_once</span>('Myself.class.php'<span>);
</span><span> 4</span>     <span>$parameter</span>=<span>array</span><span>(
</span><span> 5</span>         'uri'=>'http://localhost/',
<span> 6</span>         'location'=>'http://localhost/soap/soapServer.php'
<span> 7</span> <span>        );
</span><span> 8</span>     <span>$soapServer</span>=<span>new</span> SoapServer(<span>null</span>,<span>$parameter</span><span>);
</span><span> 9</span>     <span>$soapServer</span>->setClass('Myself'<span>);
</span><span>10</span>     <span>$soapServer</span>-><span>handle();
</span><span>11</span> ?>
Copy after login

SoapServer有两种操作模式:

上面举例的是non-WSDL模式,在实例化SoapServer类时,一个参数是放WSDL文件,在non-WSDL模式里,可以为空,把配置参数以数组的形式写在第二个参数

如果用的是WSDL模式,可以直接用WSDL文件让服务器读取配置参数,此时可以省略第二个数组参数

配置参数有许多,上面为简单举例只列出2个,具体大家可以在网上查查

uri  --命名空间

location  --服务地址

1、WSDL模式  在WSDL模式中,构造器可以使用WSDL文件名作为参数,并从WSDL中提取服务所使用的信息。

2、non-WSDL模式  在non-WSDL模式中,使用参数来传递要使用的信息,用来管理服务的行为。

在SoapServer类的众多方法中,有三个方法比较重要。它们是SoapServer::setClass()、SoapServer::addFunction()、SoapServer::handle()。

特别注意,在handle方法之前之后均不能输出任何参数,否则会出错。

3、soapClient.php  --客户端类,使用服务

<span> 1</span> <?<span>php
</span><span> 2</span>     <span>//</span><span>客户端</span>
<span> 3</span>     <span>$parameter</span>=<span>array</span><span>(
</span><span> 4</span>         'uri'=>'http://localhost/',
<span> 5</span>         'location'=>'http://localhost/soap/soapServer.php'
<span> 6</span> <span>        );
</span><span> 7</span>     <span>try</span><span>{
</span><span> 8</span>         <span>$soapClient</span>=<span>new</span> SoapClient(<span>null</span>,<span>$parameter</span><span>);
</span><span> 9</span>         <span>echo</span> <span>$soapClient</span>-><span>info();
</span><span>10</span> 
<span>11</span>     }<span>catch</span>(<span>Exception</span> <span>$e</span><span>){
</span><span>12</span>         <span>echo</span> <span>$e</span>-><span>getMessage();
</span><span>13</span> <span>    }
</span><span>14</span> 
<span>15</span> ?>
Copy after login

SoapClient类可以作为给定WebServices的客户端。
它有两种操作形式:(和SoapServer的两种模式差不多)
1、WSDL 模式

2、Non-WSDL 模式

 

以上就是利用PHP SOAP扩展实现的简单WebServices,我们访问soapClient.php试试看

轻松搞定~

 

附:

现在大多的WebServices接口的返回值是JSON或XML,我们可以在内部自己定义赋值。

常用函数 file_get_contents、json_encode、json_decode等

这里有篇关于json操作时该注意的事项:http://www.cnblogs.com/lichenwei/p/3888586.html

把文件用二进制读取,然后把他作为xml的实体传递就好了 查看原帖>>

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. 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,
