Implementation process of WSDL and soap calls under PHP5

One 、 Basic concepts

SOAP（Simple Object Access Protocol ） Simple object access protocols are decentralized or Distributed A simple protocol for exchanging information in the environment of , It's based on XML The agreement , It has four parts ：SOAP encapsulation (envelop), Encapsulation definition A description of what is in the message , Who sent it , Who should accept and deal with it and how to deal with them ;SOAP Encoding rules （encoding rules）, An instance that represents the data type that the application needs to use ; SOAP RPC Express (RPC representation), Represents the protocol for remote procedure calls and replies ;SOAP binding （binding）, Exchange information using underlying protocols .

WSDL（Web Service Description Language） It's just a description XML Web Standards of service XML Format ,WSDL from Ariba、Intel、IBM And Microsoft and other developers . It defines a given... In an abstract way independent of the concrete language Web Service receiving and sending Related operations and messages . By definition , You can't put WSDL As an object interface definition language , for example ,CORBA or COM Such as application architecture will use object interface definition language . WSDL Keep the agreement neutral , But it does have bindings built in SOAP Support for , Thus the same as SOAP Established an inseparable connection . therefore , When I discuss in this article WSDL When , I'll assume you hold SOAP As your communication protocol .

SOAP and WSDL Although it is web service Two standards of , But there is no necessary connection between the two , Can be used independently . The relationship between them is similar HTTP and Html The relationship between . The former is an agreement , The latter is for a Web Server Description of .

Two 、PHP5 Configuration below

stay php The configuration file for php.ini in , find

extension=php_soap.dll

Copy

And then, you can put the ; Remove the number , And then restart web service

3、 ... and 、 Inquire about web service Methods and parameters 、 data type

The inbound interface of a provincial telecom company is http://***.******.com/services/AcceptedBusiness?wsdl We use SoapClient Of __geunctions() and __getTypes() Method to view the methods of the interface , Parameters and data types Only __getFunctions The interfaces listed in can be soap call . Create code under the root directory soap.php

<?php
header("content-type:text/html;charset=utf-8");
try {
    $client = new SoapClient("http://***.******.com/services/AcceptedBusiness?wsdl");
    print_r($client->__getFunctions());
    print_r($client->__getTypes());  
} catch (SOAPFault $e) {
    print $e;
}
?>

Copy

Run in browser ：http://localhost/soap.php after , The results are as follows

Array
(
    [0] => ArrayOf_xsd_anyType introduceAcceptedBusiness(string $c3, string $c4, string $linkman, string $linknum, string $num, string $idcard, string $remark, string $address)
    [1] => ArrayOf_xsd_anyType introduceAcceptedBusinessByAiZhuangWei(string $subname, string $linkphone, string $idcard, string $address, string $businesstype, string $marketcode, string $surveycode, string $commanager, string $commanagerphone, string $bendiwang, string $fenju, string $zhiju, string $remark)
    [2] => string introduceAcceptedBusinessByStandardInterface(string $xmlStr)
    [3] => string introduceAcceptedBusinessByCallOut(string $xmlStr)
    [4] => string introduceAcceptedBusinessByYddj(string $xmlParam)
    [5] => ArrayOf_xsd_anyType queryAcceptedBusinessByAiZhuangWei(string $surveycode, string $starttime, string $endtime)
    [6] => string queryCallOutOrderByConfig(string $xmlParam)
)
Array
(
    [0] => anyType ArrayOf_xsd_anyType[]
)

Copy

There's a way introduceAcceptedBusinessByStandardInterface(string $xmlStr), It will be the interface to be used mentioned in the development document , Parameter is xml character string

In addition, some interfaces mention SoapHeader authentication , It's about joining __setSoapHeaders Method , Details can be viewed http://php.net/manual/zh/soapclient.setsoapheaders.php

Four 、 Submit the receipt

This step is to splice according to the development documents xml character string , And then as a introduceAcceptedBusinessByStandardInterface Parameters passed in establish acceptedbusiness.php, The contents are as follows

<?php
header("content-type:text/html;charset=utf-8");
try {
    $client = new SoapClient('http://***.*******.com/services/AcceptedBusiness?wsdl');
    $xml = "
    <?xml version='1.0' encoding='UTF-8' ?>
    <PACKAGE>

    </PACKAGE>
  ";
    $return = $client->introduceAcceptedBusinessByStandardInterface($xml);
    print_r($return);
} catch (SOAPFault $e) {
    print_r('Exception:'.$e);
}
?>

Copy

After execution in the browser , return

<?xml version="1.0" encoding="UTF-8"?>
<PACKAGE>
    <STATUS>0</STATUS>
    <REASON> Order entry succeeded !</REASON>
    <ORDERSEQ>2014100905523549742</ORDERSEQ>
