Some time ago, I had a long struggle with the issue of webservice. I wanted to write it in the thinkphp framework, but it could not be implemented. so far, I have only learned how to develop interfaces without frameworks.

To share the resource, follow these steps:

First, the files I created are:

Api. php api interface files

Api. wsdl

Cometrue. php registers the execution file of all the content of the service api class.

Creat_wsdl.php: create the method file for executing the wsdl file

Soap files that must be called by SoapDiscovery. class. php (you can query and download them online)

Step 1: create a service folder to store your api project

Step 2: Download the SoapDiscovery. class. php file and put it in your service folder.

Step 3: Create your own api File api. php under the service folder. the file content is as follows:

The code is as follows:

Class api {
// My test interface method
Public function test (){
Return "hello world ";
}
}
?>

Now, after writing our interface, we start to generate the wsdl file for this interface.

Part 4: write an execution program that generates the wsdl file. here I will create a new file creat_wsdl.php, which is also placed under the Directory of the service level. the content is as follows:

The code is as follows:

Include ("api. php ");
Include ("SoapDiscovery. class. php ");
$ Disc = new SoapDiscovery ('api ', 'service'); // api class file name, service interface Directory
$ Disc-> getWSDL ();
?>

Step 5: execute the creat_wsdl.php file

Then, an api. wsdl file is added to the service folder, as shown in:

Step 6: register all methods in the api file. in the service folder, create a new registration file named "cometrue. php". the file content is as follows:

The code is as follows:

$ Server = new SoapServer ('api. wsdl ', array ('soap _ version' => SOAP_1_2); # the Service. wsdl file is generated above.
$ Server-> setClass ("api"); // register all methods of the Service class
$ Server-> handle ();
?>

After the file is created, execute the file and register all the content in the class file. let's test this interface.

Step 7: add the called program at the bottom of the api class file api. php, and the content of the api. php file is as follows:

The code is as follows:

Class api {
// My test interface method
Public function test ($ ){
Return $;
}
}
$ Server = new SoapServer ('api. wsdl ', array ('soap _ version' => SOAP_1_2); # the Service. wsdl file is generated above.
$ Server-> setClass ("api"); // register all methods of the Service class
$ Server-> handle ();
?>

Step 7: test. create a test file named test. php at any location outside the service (as long as the file can be accessed). the file content is as follows:

The code is as follows:

$ X = new SoapClient ("http://rbac.local/service/api.php? Wsdl "); // The link here is replaced by your own access link
Echo $ x-> test ('OK ');
?>
