Question

原始问题：

我试图从SOAP API wsdl链接获取数据。我的代码如下。但是我得到了这个错误。任何人都可以帮忙吗？

错误消息：OperationFormatter遇到无效的Message正文。预计会找到节点类型＆＃39;元素＆＃39;名字＆＃39; GetLocalRates＆＃39;和命名空间＆＃39; http://tempuri.org/＆＃39;。找到节点类型＆＃39;元素＆＃39;有名字＆＃39; soapenv：信封＆＃39;和命名空间＆＃39; http://www.w3.org/2003/05/soap-envelope＆＃39;

修正：使用下面而不是XML信封。非常感谢，@ Marcel。你是一个伟大的救世主。

$requestParams = array( 'credentials' => array('AgentCode' => $acode,
                                               'HashedPassword' => $hpass,

$response = $client->GetLocalRates( $requestParams );

Answer 1

提前感谢您使用缺失的数据更新了问题。此示例是一个本机php示例，演示如何以面向对象的方式使用soap函数和类型。

<强> 1。类型和类

正如您在types数组中看到的，有几种类型声明为 struct 。如果你愿意这样说，结构可以称为PHP类。所以让我们从每个结构中创建一个php类。

class EzCredentialStruct
{
    public $AgentCode;

    public $HashedPassword;

    public $Username;

    public function getAgentCode() : string
    {
        return $this->AgentCode;
    }

    public function setAgentCode(string $AgentCode) : EzCredentialStruct
    {
        $this->AgentCode = $AgentCode;
        return $this;
    }

    public function getHashedPassword() : string
    {
        return $this->HashedPassword;
    }

    public function setHashedPassword(string $HashedPassword) : EzCredentialStruct
    {
        $this->HashedPassword = $HashedPassword;
        return $this;
    }

    public function getUsername() : string
    {
        return $this->Username;
    }

    public function setUsername(string $Username) : EzCredentialStruct
    {
        $this->Username = $Username;
        return $this;
    }
}

class GetLocalRatesStruct
{
    public $credentials;

    public $payincurcode;

    public $transferType;

    public function getCredentials() : EzCredentialStruct
    {
        return $this->credentials;
    }

    public function setCredentials(EzCredentialStruct $credentials) : GetLocalRatesStruct
    {
        $this->credentials = $credentials;
        return $this;
    }

    public function getPayincurcode() : string
    {
        return $this->payincurcode;
    }

    public function setPayincurcode(string $payincurcode) : GetLocalRatesStruct
    {
        $this->payincurcode = $payincurcode;
        return $this;
    }

    public function getTransferType() : string
    {
        return $this->transferType;
    }

    public function setTransferType(string $transferType) : GetLocalRatesStruct
    {
        $this->transferType = $transferType;
        return $this;
    }
}

这两个类是types数组中所有结构的示例。因此，将所有结构写下来作为类。您稍后会注意到这个好处。

<强> 2。 Soap Client和classmap选项

现在，当我们将webservice的已使用类型声明为类时，我们可以启动soap客户端。使用正确的选项启动soap客户端非常重要。始终将客户端包装在try / catch块中。

try {
    $options = [
        'cache_wsdl' => WSDL_CACHE_NONE, 
        'soap_version' => SOAP_1_2,
        'trace' => true,
        'classmap' => [
            'EzCredential' => 'EzCredentialStruct',
            'GetLocalRates' => 'GetLocalRatesStruct',
        ],
    ];

    $wsdl = 'path/to/the/webservice/endpoint?wsdl';

    $client = new \SoapClient(
        $wsdl,
        $options,
    );
} catch (\SoapFault $e) {
    // error handling
}

如您所见，options数组中有一个classmap键。 classmap将类型路由到特定的php类。在这个例子中，我们只使用前面定义的两个示例类型类。 soap客户端现在可以自动创建webservice所需的xml字符串。

第3。全部放在一起

现在，正如我们所需要的所有肥皂请求一样，我们的代码应该如下所示。

$credentials = (new EzCredentialStruct())
    ->setAgentCode($agentCode)
    ->setHashedPassword($hashedPassword)
    ->setUsername($username);

$request = (new GetLocalRatesStruct())
    ->setCredentials($credentials)
    ->setPayincurcode($code)
    ->setTransferType($transferType);

$result = $client->GetLocalRates($request);

<强>结论

乍一看，这种方法可能看起来更像是工作。但是，将这些类型与webservice声明的每个结构的函数和编程类分开是有意义的。 webservice函数的调用将更容易，因为我们只传递一个对象作为参数。没有更奇怪的数组结构。一切都取而代之，可以重复使用。

PS：此代码未经过测试。不建议在生产中使用它。此代码仅作为示例。它可能包含错误。
