Communication between webServicephp's soap and nusoap server and client

PHP SOAP Server

It is very easy to set up a SOAP server with PHP and Soap. Basically, you just write the functions you want to expose to your Web service, and then register them with Soap. There are also two steps required to complete the establishment of the PHP SOAP server. First, you have to create an instance of the Soap object in your PHP code, and then use the HTTP POST method to pass the original data to Soap for processing

Soap has been integrated in php5. The use of SOAP is relatively simple, and the most commonly used one is The classes are SoapServer and SoapClient, where SoapServer is used to create the Webservice server, and the SoapClient class is used to call the Webservice, which is the client. Since soap is integrated from php5, you only need to enable the soap component in php.ini.

Take Windows as an example:

Communication between webServicephps soap and nusoap server and client

extension=php_soap.dll

Soap instance:

Communication between webServicephps soap and nusoap server and client. First create a service end, since the integrated php5 does not need to introduce any soap support files, it can be created directly. For example, the access address is set to http://Communication between webServicephps soap and nusoap server and clientCommunication between webServicephps soap and nusoap server and client7.0.0.Communication between webServicephps soap and nusoap server and client/test.php.

Communication between webServicephps soap and nusoap server and client. Call the soap service you just created. Similarly, since the integrated php5 does not need to introduce any soap support files, you can just call it directly.

$demo= $client ->demo();var_dump(

$demo);

However, Nusoap is more flexible than soap. Their operation processes are basically the same, but there are slight deviations in the processing process. The use of NuSOAP is also relatively simple. The most commonly used classes are soap_server and nusoap_client, among which soap_server It is used to create the Webservice server, and the class nusoap_client is used to call the Webservice, which is the client. The definitions of these two classes are in lib/nusoap.php, so we need to reference this file when creating or calling the Webservice interface program.

NuSoap is a WebService programming tool in PHP environment, used to create or call WebService. It is an open source software, which is a series of PHP classes written entirely in PHP language that sends and receives SOAP messages through HTTP. It is developed by NuSphere Corporation (http://dietrich.ganx4.com/nusoap/). One advantage of NuSOAP is that it does not require extension library support. This feature allows NuSoap to be used in all PHP environments and is not affected by server security settings.

Provide nusoap download: nusoap-0.9.5

Nusoap instance:

Communication between webServicephps soap and nusoap server and client. The first thing to do is still to create the server. I just mentioned that there is a slight deviation, so I created this on the server. First introduce nusoap Support class library

$soap= newsoap_server();

$HTTP_RAW_POST_DATA= isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA: ''

Explanation:

WSDL
WSDL is an XML language used to describe Web Services. It is a machine-readable format that provides all the information necessary to access the service to the Web Service client. NuSOAP specifically provides a class to parse WDSL files and extract information from them. The soapclient object uses the wsdl class to make it easier for developers to call services. By creating the message with the help of WSDL information, the programmer only needs to know the name and parameters of the operation to call it.

Using WSDL through NuSOAP provides the following advantages:
All service metafiles, such as namespaces, endpoint URLs, parameter names, etc., can be obtained directly from the WSDL file, thus allowing clients Dynamically adapt to server-side changes. Because this data is always available from the server, this data no longer needs to be hard-coded in user scripts.
It allows us to use soap_proxy class. This class is derived from the soapclient class and adds methods corresponding to the operations detailed in the WDSL file. Now users can directly call these methods through it.
The soapclient class contains a getProxy() method, which returns an object of the soap_proxy class. The soap_proxy class is derived from the soapclient class, adds methods corresponding to the operations defined in the WSDL document, and allows the user to call an endpoint's remote method. This only applies if the soapclient object is initialized with a WDSL file. The advantage is ease of use for users, the disadvantage is performance – creating objects in PHP is time-consuming – and this functionality serves no utilitarian purpose.

Run the server url you just created, http://Communication between webServicephps soap and nusoap server and clientCommunication between webServicephps soap and nusoap server and client7.0.0.Communication between webServicephps soap and nusoap server and client/test.php. The results after execution are as follows.

Click on the method name. In this way, by adding a few lines of code to the service, we provide a visual document for the service using NuSOAP. But that's not all we can do.

We add some WSDL calls in the service by using NuSOAP. We can generate WSDL and some other documents for the service. In contrast, there is not much we can do in the client, at least in our simple example. The client shown below is no different from the client that does not use WSDL. The only difference is that parsing the soapclent class is done by providing the URL of the WSDL instead of the service endpoint as before.

NuSoap can set the encoding when calling WebService. The solution to garbled codes is as follows:

Communication between webServicephps soap and nusoap server and client Communication between webServicephps soap and nusoap server and client 3 4

$client = newnusoap_client("http://Communication between webServicephps soap and nusoap server and clientCommunication between webServicephps soap and nusoap server and client7.0.0.Communication between webServicephps soap and nusoap server and client/test.php?wsdl",true); $client->soap_defencoding = 'utf-8'; $client->decode_utf8 = false; $client->xml_encoding = 'utf-8';

The file code cannot have any output, otherwise an error similar to the following will be reported when calling:
XML error parsing SOAP payload on line x (line number): Reserved XML Name

If there is a conflict between nusoap's SoapClient class and php5's built-in SOAP class when turning on php5's built-in soap (I don't have such a situation here, both are open at the same time):
Solution
Communication between webServicephps soap and nusoap server and client. Modify php. ini does not load the built-in soap extension of php5 (php_soap.dll under windows).
Communication between webServicephps soap and nusoap server and client. Some people also renamed the SoapClient class of nusoap.

At this point, whether it is php5’s built-in soap or nusoap extension class, webservice is a solution. From some of the examples above, nusoap is more flexible, and for simple webserice communication, php5 The built-in soap is faster, no matter which one you choose, just choose one.

The above introduces the communication between the soap and nusoap server and client of webServicephp, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
