webservicephp soap and Nusoap server-to-client communication

PHP SOAP Server

It is easy to build SOAP servers with PHP and SOAP. Basically, you just write out the functions you want to expose to your Web service, and then use soap to register them. Another two steps will be required to complete the creation of the PHP soap server. First you also create an instance of the SOAP object in your PHP code, and then use the HTTP POST method to pass the raw data to soap for processing

SOAP is being integrated in php5, and the use of soap is relatively straightforward, with the most commonly used classes being soapserver and SoapClient, where soapserver is used to create the WebService server, The class soapclient is used to call WebService, which is the client. Since soap is integrated from PHP5, only the SOAP component can be opened in php.ini.

Take windows as an example:

1	extension=php_soap.dll

Soap instance:

1, first create the server side, because the integrated PHP5 does not need to introduce any SOAP support files, directly created, such as the access address set to http://127.0.0.1/test.php.

01 02 03 04 05 06 07 08 09 10 11

classtest{ functiondemo(){ return'hello word'; } } //开始创建webservice //null可传入ip，第二个参数类似于授权标识，调用时会用到 $webService= newSoapServer(null,array('uri'=>'test.php')); //设置需要提供的类，setClass不难理解吧？ $webService->setClass('test'); $webService->handle();

At this point, the SOAP service-side creation is complete.

2, call the SOAP service just created, similarly, because the integrated PHP5 does not need to introduce any SOAP support files, directly call.

1 2 3 4 5 6 7

$client= newSoapClient(null,array( "location"=> 'http://127.0.0.1/test.php', "uri"=> 'test.php', //请求标识，服务器和客户端必须对应 )); //至此，便可调用类里面的方法了 $demo= $client->demo(); var_dump($demo);

However, for Nusoap, the flexibility is stronger than soap, their operation process is basically consistent, but the processing process has a little deviation, the use of Nusoap is relatively simple, the most commonly used classes are soap_server and nusoap_client, where SOAP_ The server is used to create the WebService service side, and class nusoap_client is used to invoke WebService, which is the client. The definitions of these two classes are all in lib/nusoap.php, so we need to reference the file when we create or invoke the WebService interface program.

Nusoap is a WebService programming tool for creating or invoking webservice in a PHP environment. It is an open source software, developed by Nusphere Corporation (http://dietrich.ganx4.com/nusoap/), a series of PHP classes written entirely in PHP that send and receive SOAP messages over HTTP. One advantage of Nusoap is that there is no need for extended library support, which allows Nusoap to be used in all PHP environments and is not affected by server security settings.

Available nusoap Download: nusoap-0.9.5

Examples of Nusoap:

1, the first thing to do is still to create a service side, just said there is a little deviation, on the server to create this, first introduced Nusoap support class library

01 02 03 04 05 06 07 08 09 10 11

//引入nusoap支持类库 require_once('lib/nusoap.php'); $soap= newsoap_server(); $soap->configureWSDL('test'); //这里要说明一下register这个函数，第一个参数是需要调用的方法，第二个参数是传入的数据，第三个参数是传出的数据。 $soap->register('GetTestStr', array("name"=> "xsd:string"),// 参数，默认为 "xsd:string" array("return"=> "xsd:string") ); $HTTP_RAW_POST_DATA= isset($HTTP_RAW_POST_DATA) ?$HTTP_RAW_POST_DATA: ''; $soap->service($HTTP_RAW_POST_DATA);

At this point, the NUSOAP server has been created, assuming the address is http://127.0.0.1/test.php.

2, call Nusoap. Before this I encapsulated a bit here, the file is class.nuSoapApi.php, the code is as follows.

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21st 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90

From here, call the execution process:

//定义webservice的请求url define('SERVICEDTS_WEBSERVER_URL','http://127.0.0.1/test.php?wsdl'); //引入刚刚封装的类 require_once('lib/class.nuSoapApi.php'); //调用nusoap扩展类 $client= newNusoapApi(SERVICEDTS_WEBSERVER_URL,true); $client->setSoapDefenCoding('utf-8'); $client->setDeCodeUtf8(false); $client->setXmlEnCoding('utf-8'); $paras= array('name'=> 'hkshadow'); $client->setArrParam($paras); $result= $client->getRequestData('GetTestStr'); if(! $err= $client->getError ()) { echo" 返回结果： ", $result; } else{ echo" 调用出错： ", $err; } //输出Hello, { hkshadow } !

Explanation:

Wsdl
WSDL is an XML language used to describe a Web service. It is a machine-readable format that provides all the information necessary to access a service to a Web service client. Nusoap specializes in providing a class for parsing WDSL files and extracting information from them. The SoapClient object uses a WSDL class to alleviate the difficulty of the developer invoking the service. With the help of the WSDL information to create the message, the programmer simply needs to know the name and parameters of the operation to invoke it.

Using WSDL with NUSOAP provides the following advantages:
All service meta-files, such as namespaces (namespaces), endpoint URLs, parameter names (parameter names), etc., can be obtained directly from the WSDL file, allowing the client to dynamically adapt to server-side changes. Because it is readily available from the server, this data no longer requires hard coding in user scripts.
It allows us to use the Soap_proxy class. This class derives from the SoapClient class and adds a method that corresponds to the operations detailed in the WDSL file. These methods can now be called directly by the user through it.
The SoapClient class contains a GetProxy () method that returns an object of a Soap_proxy class. The Soap_proxy class derives from the SoapClient class, adding a method that corresponds to the operation defined in the WSDL document, and allows the user to invoke a endpoint remote method. This applies only to cases where the SoapClient object is initialized with the Wdsl file. The advantage is that it is easy for users to use, and the disadvantage is that the creation of objects in performance –php is time-consuming – and is not serviced for utilitarian purposes (and this functionality serves no utilitarian purpose).

//调用nusoap扩展类 $client= newNusoapApi(SERVICEDTS_WEBSERVER_URL,true); $client->setSoapDefenCoding('utf-8'); $client->setDeCodeUtf8(false); $client->setXmlEnCoding('utf-8'); $paras= array('name'=> 'hkshadow'); $client->setArrParam($paras); // $result = $client->getRequestData('GetTestStr'); //生成proxy类 $proxy= $client->getProxy(); //调用远程函数 $sq= $proxy->GetTestStr('Bruce Lee'); if(!$err=$proxy->getError()) { print_r($sq); } else{ print"ERROR: $err"; } print'REQUEST:＜xmp＞'.$p->request.'＜/xmp＞'; print'RESPONSE:＜xmp＞'.str_replace('><',">\n<", $p->response).'＜/xmp＞';

Run the service-side url,http://127.0.0.1/test.php that you just created, and follow the results below.

Click the method name. This allows us to provide a visual document to the service by using Nusoap by adding a few lines of code to the service. But that's not all we can do.

We add some WSDL calls in the service by using NUSOAP we can generate WSDL for the service and some other documentation. In contrast, there are few things we can do in the client, at least in our simple example. The client shown below is no different from the client without WSDL, the only difference being that parsing soapclent class is done by providing the URL to the WSDL, not the previous service endpoint.

Nusoap call WebService when the encoding can be set, garbled solution is as follows:

1 2 3 4

$client= newnusoap_client("http://127.0.0.1/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 the call will report an error similar to the following:
XML error parsing SOAP payload on line x (row number): Reserved XML Name

If the PHP5 built-in soap is turned on, Nusoap's SoapClient class and PHP5 's built-in soap class are in conflict (I don't have a situation like this, 2 are open at the same time):
Solution Solutions
1. Modify php.ini does not load PHP5 built-in SOAP extensions (Windows is Php_soap.dll).
2. There is also a renaming of the SoapClient class for Nusoap.

At this point, whether it is php5 built-in soap or nusoap extension class, and for WebService is a solution, from the above examples are visible, nusoap appear more flexible, and for the simple webserice communication, PHP5 built-in soap is faster, regardless of which one you choose.
