SoapServer::addFunction

(PHP 5, PHP 7, PHP 8)

SoapServer::addFunction添加一个或多个函数来处理 SOAP 请求

说明

public SoapServer::addFunction(array|string|int $functions): void

为远程客户端导出一个或多个函数

参数

functions

导出一个函数,将函数名作为字符串传递给这个参数。

导出多个函数,将一组函数名作为数组传递。

导出所有函数,传递特殊常量 SOAP_FUNCTIONS_ALL.

注意:

functions 接收的所有输入参数必须同时和 WSDL 文件中定义的顺序一样(它们不应该接收任何输出变量作为参数)并且返回一个或多个值。如果要返回多个值,它们必须返回一组被命名的输出参数作为数组。

返回值

没有返回值。

示例

示例 #1 SoapServer::addFunction() 示例

<?php

function echoString($inputString)
{
return
$inputString;
}

$server->addFunction("echoString");

function
echoTwoStrings($inputString1, $inputString2)
{
return array(
"outputString1" => $inputString1,
"outputString2" => $inputString2);
}
$server->addFunction(array("echoString", "echoTwoStrings"));

$server->addFunction(SOAP_FUNCTIONS_ALL);

?>

Be careful with SOAP_FUNCTIONS_ALL, as it adds ALL availiable PHP functions to your server.

This can be a potential security threat, imagine clients doing this:

echo $client->file_get_contents("c:\\my files\\my_passwords.doc");

And voila, they have the contents of your file my_passwords.doc.

You may be left wondering, as I was, how to return a complex type - consider the following WSDL snippets, for a method called Login:

<xs:element name="Login">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="1" name="username" type="xs:string" />
<xs:element minOccurs="0" maxOccurs="1" name="password" type="xs:string" />
</xs:sequence>
</xs:complexType>
</xs:element>

<xs:complexType name="UserInfo">
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="1" name="Id" type="xs:string" />
<xs:element minOccurs="0" maxOccurs="1" name="Name" type="xs:string" />
<xs:element minOccurs="0" maxOccurs="1" name="Nickname" type="xs:string" />
<xs:element minOccurs="0" maxOccurs="1" name="Email" type="xs:string" />
</xs:sequence>
</xs:complexType>

<xs:element name="LoginResponse">
<xs:complexType>
<xs:sequence>
<xs:element minOccurs="0" maxOccurs="1" name="LoginResult" type="s0:UserInfo" />
</xs:sequence>
</xs:complexType>
</xs:element>

Here's a working Login function that I've added with add SoapServer::addFunction

function Login($username, $password)
{
return array("LoginResult", array("Id"=>1, "Name"=>"Nathan", "Nickname"=>"Nathan", "Email"=>"email address") );
}

The UserInfo complextype is represented by the inner array. The outer array has just one element, "LoginResult". The LogineResponse element seems to be treated as a one-member array by PHP.

In response to comment by Nathan O'Sullivan about returning (or passing) a complex type, you can also use the stdClass() object.

Assume you define a complex type like so:

<xsd:complexType name="TestType">
<xsd:all>
<xsd:element name="A" type="xsd:string" />
<xsd:element name="B" type="xsd:int" />
<xsd:element name="C" type="xsd:boolean" />
</xsd:all>
</xsd:complexType>

To use an object in place of an array you can do:

$test = new stdClass();
$test->A = "test string";
$test->B = 45;
$test->C = false;

$result = $client->Test($test);
