What is web service? I won’t go into details. You can refer to the encyclopedia descriptionweb service Baidu Encyclopedia.

Soap is a protocol and a technical specification used by web service implementation.

There are two ways to implement the interface of web service, one is the way that needs to generate wsdl documents, and the other is the way that does not need to generate wsdl documents.

Before actual operation, first check whether your environment supports soap, then modify the php.ini configuration file and set the "soap.wsdl_cache_enabled" item to 0.

No need to generate wsdl document

This method is simpler than the method that needs to generate wsdl document, but some methods are not supported, such as Get the __getFunctions() of the operation method. Whether it is suitable depends on your choice.

server side ts1.php

'sampleA')); $ss->setClass('testA'); $ss->handle();

In the server side ts1.php file, create a class, then create SoapServer and make settings, uri is used to ensure consistency sex.

client side tc1.php

'http://10.0.0.232:1075/soap/ts1.php', 'uri'=>'sampleA' )); echo $client->sayHi('Taylor,Swift'); echo "
"; echo $client->add(1,2);

On the client side, use the SoapClient object to make a request. Location specifies the specific address of the request. The value of uri is the same as that set on the server side. Consistent, used to ensure consistency.

Enter http://10.0.0.232:1075/soap/tc1.php in the browser to access. You can see the output as shown below:

This method does not need to generate a wsdl document and is easy to implement. However, because there is no wsdl document, the client cannot obtain the relevant operation methods. With the method of generating a wsdl document, the client can independently generate a wsdl document based on a request address. Get all interfaces exposed by the server.

How to generate wsdl document

The wsdl document is an xml document, which can usually be generated using the public class library SoapDiscovery. I can share it with Baidu Netdisk if needed. Download SoapDiscovery.class.php directly.

server-side ts2.php

getWSDL(); file_put_contents(WSDL_FILE, $str); } $ss = new SoapServer(WSDL_FILE); $ss->setClass('testD'); $ss->handle(); class testD{ public function sayHello($world){ return 'hello,'.$world; } public function add($a, $b){ return $a+$b; } }

The server-side ts2.php first checks whether the required wsdl file exists. If it does not exist, create it, and then create the SoapServer object. And set it up, because you are using a wsdl document, so you can directly write the address of the wsdl document when using new SoapServer.

client side tc2.php

__getFunctions()); echo "
"; echo $client->sayHello('Avril Lavigne'); echo "
"; echo $client->add(9,8);

In the tc2.php file on the client side, when creating the SoapClient object, directly fill in the address of the requested wsdl document. This document is generated by ts2.php.

Now, the server-side ts2.php and the client-side tc2.php have been written, so now we need to request ts2.php. Why request it?

Because we need to create the wsdl file through ts2.php first. Of course, we only need to do this for the first time. After the wsdl document is created, there is no need to do it again.

(If ts2.php is modified later, you still need to delete the old wsdl document, and then request ts2.php again to generate a new wsdl document.)

1. Request ts2.php is used to generate wsdl document http://10.0.0.232:1075/soap/ts2.php.

2. Request tc2.php to view the return result:

3. Through the browser, directly access the address of the wsdl document, and you can see the wsdl document. Specific content:

php soap also supports various other operations, such as authentication, header settings, etc. If necessary, you can refer to the official documentation for these functions.
