About the simple architecture of webservice implementation in php

This article mainly introduces four simple architectural methods and examples of webservice implementation in PHP. Friends in need can refer to the following

1: PHP's own SOAP
All webservices include the server (server) and client (client).
To use PHP's own soap, you must first install and enable the extension. Let’s look at the specific code
First of all, this is the server-side implementation:

<?php   
class test   
{   
    function show()   
    {   
        return &#39;the data you request!&#39;;   
    }   
}   
function getUserInfo($name)   
{   
    return &#39;fbbin&#39;;   
}   
//实例化的参数手册上面有，这个是没有使用wsdl的，所以第一个参数为null，如果有使用wsdl，那么第一个参数就是这个wsdl文件的地址。   
$server = new SoapServer(null, array(&#39;uri&#39; =&#39;http://soap/&#39;,&#39;location&#39;=&#39;http://localhost/test/server.php&#39;));   
$server->setClass(&#39;test&#39;);   
//$server->addFunction(&#39;getUserInfo&#39;);   
$server->handle();   
?>

Then the client

$soap = new SoapClient(null, array('location'='http://localhost/test/server.php','uri' ='http://soap/'));     
echo $soap->show();   
//得到：'the data you request!'   
//echo $soap->getUserInfo('sss');

It’s that simple. At that time, it was just a very simple example. In fact, there was a lot of communication This is how the mechanism is implemented!

2: PHPRPC
First go to the official website (http ://www.phprpc.org/zh_CN/) Go to download the latest version of phprpc. After decompression, there will be relevant files. We divide the files (server and client files) as follows:
Server files:

dhparams   
dhparams.php   
phprpc_server.php   
bigint.php   
compat.php   
phprpc_date.php   
xxtea.php

Client files:

phprpc_client.php   
bigint.php   
compat.php   
phprpc_date.php   
xxtea.php

We put the server files in the server folder, then put the client files in the client folder, and then in the server folder Create a new file (server.php) as the service, and then create a new file (client.php) as the client. The respective codes are as follows:
server side:

<?php   
include_once"phprpc_server.php"; //加载phprpc文件   
$server = new PHPRPC_Server();   
$server->add(&#39;getUser&#39;);   
$server->setDebugMode(true);   
$server->start();   
function getUser( )   
{   
    return ‘the data you request!&#39;;   
}

client side:

[code]   
<?php   
include_once "phprpc_client.php";   
$client = new PHPRPC_Client(&#39;http://127.0.0.1/phpservice/phprpcserver/server.php&#39;);   
$data = $client->getUser();   
var_dump($data);   
//得到：the data you request!

After mentioning wsdl above, we will talk about how to generate it.

3: Open source NUSOAP
Go online first Download the latest version of nusoap. The latest version is 0.9.5. After decompression, you will get a lib folder. Put this file into the server and client respectively, and then create them separately on the server and client. The server.php and client.php files serve as communication files.
The server files are as follows:

<?php   
ini_set("soap.wsdl_cache_enabled", 0);//关闭缓存   
require_once("lib/nusoap.php"); //加载nusoap文件   
$server = new soap_server;   
$server->configureWSDL(&#39;nusoasp&#39;);//设定服务的名称，使用的wsdl来通信，如果不适用wsdl将会更简单，网上有很多的例子   
$server->register(&#39;getUserInfo&#39;, array(&#39;name&#39;="xsd:string", &#39;email&#39;="xsd:string"), array(&#39;return&#39;="xsd:string"));   
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : &#39;&#39;;   
$server->service( $HTTP_RAW_POST_DATA );   
function getUserInfo($name, $email)   
{   
    return ‘the data you request!&#39;;   
}

The client files are as follows:

require_once("lib/nusoap.php");   
$client = new soapclient('http://localhost/phpservice/nusoapserver/server.php?wsdl');   
$pagram = array('fbbin', 'fbbin@foxmail.com');   
$string = $client->call('getUserInfo', $pagram);   
//得到：the data you request!

Four: HessianPHP
hessian. In fact, I personally think that it is not a webservice, it can only be said to be similar. Because it does not have the characteristics of webservice. It supports many languages. We only need to study the php version of HessianPHP now. The latest version to download is v2.0.3. After decompression, you will get a src directory, which is a core folder we need to use.
We renamed the name to HessianPHP and placed them on the server and client respectively, and then created server.php and client.php files respectively.
Server side:

<?php   
include_once &#39;HessianPHP/HessianService.php&#39;;//加载核心文件   
class TestService   
{   
    public function __construct()   
    {   
  
    }   
  
    public function add($numa, $numb)   
    {   
        return $numa + $numb;   
    }   
  
    public function check()   
    {   
        return &#39;fbbiin@gmail.com&#39;;   
    }   
}   
$test = new TestService();   
$hessian = new HessianService( $test, array(&#39;displayInfo&#39; => true) );   
$hessian->handle();//注意这里不是网上的$hessian->service(),可能是版本不一样，改了吧！我也是看了源码才知道！   
?>

Client side:

<?php   
include_once &#39;HessianPHP/HessianClient.php&#39;;   
$url = "http://localhost/phpservice/hessianserver/server.php";   
$options = new HessianOptions();   
$client = new HessianClient( $url, $options );   
$num = $client->add( 3, 5 );   
echo $num;//得到：8；   
echo $client->check();//得到：fbbiin@gmail.com；

The above four methods are webservice communication methods commonly used in the web development process. The most commonly used one is nusoap. Personally, I feel that phprpc is actually pretty good. This one is basically similar to nusoap in terms of performance. However, phprpc is commercially charged. There is also hessianPHP, which seems to use Java and uses a binary method to transmit data streams. In fact, each has its own merits. For more detailed information, please go to Baidu and Google.
Let’s talk about generating the wsdl file.
The most commonly used and relatively safe method for us to communicate on webservice is to use wsdl. This kind of file can be written by oneself, but it does not seem to be possible for some experts to write it, so we need to use a tool. zend studio to generate wsdl files.
Next we will generate the WSDL file, File->New—>Other—>Web Service—>WSDL, so that we can create a new WSDL file, as shown in the figure.

Then we will modify the WSDL file. zeng studio provides us with visual operations. Of course, if If you are good at it, of course you can change the file code. In fact, there are only a few things, and it won't be too difficult if you understand it.

After completing this step, the WSDL file will be basically available, but there are two issues that need to be paid attention to:
After completing this step, The test may fail, possibly because there is no binding. This sometimes needs to be done manually. Just right-click on the binding and select Generate Binding Content (the small box in the middle of the two large boxes).
The second thing to pay attention to is the WSDL cache of php. When testing, you generally need to turn off the WSDL cache, otherwise you may be using the original WSDL file instead of the updated one. There are two ways to turn off the cache. The first is to set soap.wsdl_cache_enabled = 0 directly in php.ini; the second is to add a statement in the php file, ini_set("soap.wsdl_cache_enabled", "0");
After doing this, you can safely test and call your server program.
That’s it, OK!
