PHP 中的 SOAP 错误:OperationFormatter 遇到无效的消息正文

SOAP Error in PHP: OperationFormatter encountered an invalid Message body

原问题:

我正在尝试从 SOAP API wsdl link 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?

Error Message: OperationFormatter encountered an invalid Message body. Expected to find node type 'Element' with name 'GetLocalRates' and namespace 'http://tempuri.org/'. Found node type 'Element' with name 'soapenv:Envelope' and namespace 'http://www.w3.org/2003/05/soap-envelope'

固定:下面使用而不是 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,
                                               'Username' => $uname),
                  'payincurcode' => $ccode,
                  'transferType' => $ttype
              );

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

预先感谢您用缺失的数据更新了您的问题。此示例是本机 php 示例,展示了如何以面向对象的方式使用 soap 函数和类型。

1.类型和 classes

如您在类型数组中所见,有几种类型声明为 struct。如果你喜欢这么说,structs 可以被称为 PHP classes。因此,让我们从每个结构中创建一个 php class。

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 class 是类型数组中所有结构的示例。因此,将所有结构记为 classes。稍后您会发现好处。

2。 Soap 客户端和 classmap 选项

现在,由于我们已将 web 服务的使用类型声明为 classes,我们可以启动 soap 客户端。使用正确的选项启动 soap 客户端很重要。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,选项数组中有一个 classmap 键。 classmap 将类型路由到特定的 php classes。在此示例中,我们仅使用我们之前定义的两个示例类型 classes。 soap 客户端现在可以自动创建网络服务需要的 xml 字符串。

3。全部放在一起

现在,我们已经拥有了正确的 soap 请求所需的一切,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);

结论

乍一看,这种方法可能看起来工作量更大。但是,对于 web 服务声明的每个结构,将类型与函数和编程 classes 分开是有意义的。 webservice函数的调用会更简单,因为我们只传递一个对象作为参数。不再有奇怪的数组构造。一切都在原位,可以重复使用。
