PHPでのコアクラスの拡張について（例SOAPクライアント）

Question

私はPHPで開発中ですが、PHPのコアクラスから拡張する必要はありません。

私はSoap WebサービスプロバイダにSOA​​Pサービスを書いているとの問題があります。そのため、PHP-CLIENTクラスでは多くの検証エラーが発生します。いずれにせよ、彼らのSOAPは "機能する"ものであり、そうではありません。

私がやりたかったのは、このクラスから拡張し、targetNamespaceがその場所と異なる名前を持つなど、検証を変更することでした。私はこれをしてはならないことを知っていますが、私はゼロからSOAPクラスを作成したくありません。

このクラス（SoapClient）から拡張しようとしていたときに、メソッドにコードが全くないことに気がつきましたが、その理由を見つけることができませんでした。私は、これらのメソッドが "C"環境下で動作するか、すでに高速化されているので、多分考えていました。これが当てはまらない場合は、このクラスのコードを見て、私のニーズに合わせて変更することが大好きです。

提案、ヒントまたは説明を歓迎します。私はSoapClientコードを添付しています。

class SoapClient { 

/** 
* (PHP 5 &gt;= 5.0.1)<br/> 
* SoapClient constructor 
* @link http://php.net/manual/en/soapclient.soapclient.php 
* @param mixed $wsdl <p> 
* URI of the WSDL file or <b>NULL</b> if working in 
* non-WSDL mode. 
* </p> 
* <p> 
* During development, WSDL caching may be disabled by the 
* use of the soap.wsdl_cache_ttl <i>php.ini</i> setting 
* otherwise changes made to the WSDL file will have no effect until 
* soap.wsdl_cache_ttl is expired. 
* </p> 
* @param array $options [optional] <p> 
* An array of options. If working in WSDL mode, this parameter is optional. 
* If working in non-WSDL mode, the location and 
* uri options must be set, where location 
* is the URL of the SOAP server to send the request to, and uri 
* is the target namespace of the SOAP service. 
* </p> 
* <p> 
* The style and use options only work in 
* non-WSDL mode. In WSDL mode, they come from the WSDL file. 
* </p> 
* <p> 
* The soap_version option should be one of either 
* <b>SOAP_1_1</b> or <b>SOAP_1_2</b> to 
* select SOAP 1.1 or 1.2, respectively. If omitted, 1.1 is used. 
* </p> 
* <p> 
* For HTTP authentication, the login and 
* password options can be used to supply credentials. 
* For making an HTTP connection through 
* a proxy server, the options proxy_host, 
* proxy_port, proxy_login 
* and proxy_password are also available. 
* For HTTPS client certificate authentication use 
* local_cert and passphrase options. An 
* authentication may be supplied in the authentication 
* option. The authentication method may be either 
* <b>SOAP_AUTHENTICATION_BASIC</b> (default) or 
* <b>SOAP_AUTHENTICATION_DIGEST</b>. 
* </p> 
* <p> 
* The compression option allows to use compression 
* of HTTP SOAP requests and responses. 
* </p> 
* <p> 
* The encoding option defines internal character 
* encoding. This option does not change the encoding of SOAP requests (it is 
* always utf-8), but converts strings into it. 
* </p> 
* <p> 
* The trace option enables tracing of request so faults 
* can be backtraced. This defaults to <b>FALSE</b> 
* </p> 
* <p> 
* The classmap option can be used to map some WSDL 
* types to PHP classes. This option must be an array with WSDL types 
* as keys and names of PHP classes as values. 
* </p> 
* <p> 
* Setting the boolean trace option enables use of the 
* methods 
* SoapClient->__getLastRequest, 
* SoapClient->__getLastRequestHeaders, 
* SoapClient->__getLastResponse and 
* SoapClient->__getLastResponseHeaders. 
* </p> 
* <p> 
* The exceptions option is a boolean value defining whether 
* soap errors throw exceptions of type 
* SoapFault. 
* </p> 
* <p> 
* The connection_timeout option defines a timeout in seconds 
* for the connection to the SOAP service. This option does not define a timeout 
* for services with slow responses. To limit the time to wait for calls to finish the 
* default_socket_timeout setting 
* is available. 
* </p> 
* <p> 
* The typemap option is an array of type mappings. 
* Type mapping is an array with keys type_name, 
* type_ns (namespace URI), from_xml 
* (callback accepting one string parameter) and to_xml 
* (callback accepting one object parameter). 
* </p> 
* <p> 
* The cache_wsdl option is one of 
* <b>WSDL_CACHE_NONE</b>, 
* <b>WSDL_CACHE_DISK</b>, 
* <b>WSDL_CACHE_MEMORY</b> or 
* <b>WSDL_CACHE_BOTH</b>. 
* </p> 
* <p> 
* The user_agent option specifies string to use in 
* User-Agent header. 
* </p> 
* <p> 
* The stream_context option is a resource 
* for context. 
* </p> 
* <p> 
* The features option is a bitmask of 
* <b>SOAP_SINGLE_ELEMENT_ARRAYS</b>, 
* <b>SOAP_USE_XSI_ARRAY_TYPE</b>, 
* <b>SOAP_WAIT_ONE_WAY_CALLS</b>. 
* </p> 
* <p> 
* The keep_alive option is a boolean value defining whether 
* to send the Connection: Keep-Alive header or 
* Connection: close. 
* </p> 
* <p> 
* The ssl_method option is one of 
* <b>SOAP_SSL_METHOD_TLS</b>, 
* <b>SOAP_SSL_METHOD_SSLv2</b>, 
* <b>SOAP_SSL_METHOD_SSLv3</b> or 
* <b>SOAP_SSL_METHOD_SSLv23</b>.

Answer 1

最終的には、解決策は全くありませんでした。

SOAPクラスを問題の多いサービスに接続する場合は、WSDL構造をダウンロードして必要なものに合わせて修正してください。

私はこの解決策が気に入らないのは、APIサプライヤが何かを変更した場合、それについて知る知識がないからです。

次のコードでは、SOAP呼び出しが固定XMLに対して呼び出され、サービスについて質問することができます。

$urlXML = "FIXEDXML.xml"; 
    $cliente = new SoapClient($urlXML, array(
     "trace" => true, 
     'soap_version' => SOAP_1_1, 
     'cache_wsdl' => WSDL_CACHE_NONE 
    )); 

    var_dump($cliente); 

    echo "<h1> FUNCIONES DISPONIBLES </h1>"; 
    echo '<pre>'; 
    $functiones = $cliente->__getFunctions(); 
    var_dump($functiones); 
    echo '</pre>'; 
} catch (Exception $exc) { 
    var_dump($exc); 
    echo $exc->getTraceAsString(); 
} 

これは誰かにとって役に立ちそうです。私はそれを機能させるために長い時間をかけていました。

Answer 2

あなたが任意のPHPクラスで行うようにするだけの操作を行います。

class mySoapClient extends SoapClient { 
    //override parent function 
    public function nativeFunction() { 
      //...some logic ... 
    } 
} 

ポイントは、あなたがあなたが望むほど簡単になりますかどうかを知る必要があるということです。サードパーティのライブラリを使用する方が簡単な場合もあります。コードにアクセスしてコードを変更する方法がわかります。
