使用 PHP/MYSQL Web 服务 (WSDL) 的 ASP.NET/C# 客户端

Question

我正在尝试访问网络服务（以下两个文件）。客户端将 ASP.NET/C# 用于其 Web 体系结构。我可以添加 Web 引用，但不知何故我无法为 wsdl 文件生成代理类。目的是使用 server.php 文件中的函数，以便我可以使用 xmlstring 在 ASP.NET 网站上显示数据。任何帮助将不胜感激。非常感谢

server.php 文件。该文件有一个 php 函数，它从 mysql 数据库中提取数据，该函数将数据作为 XML 字符串返回。

<?php
//WEB SERVICE FUNCTION TO EXTRACT DATA FROM CLIENT B INTO XML FORMAT
function getXML()
{
//CONNECT TO THE DATABASE SERVER
$dbserverIP = "xxxxxxx";
$dbusername = "xxxxxxx";
$dbpassword = "xxxxxxx";
$dbconnection = mysql_connect($dbserverIP,$dbusername,$dbpassword)  
or die ("The connection to the database server failed.");

//CONNECT TO THE DATABASE
$dbname = "xxxxxxxx";
$dbselectok = mysql_select_db($dbname,$dbconnection)
or die ("The connection to the database failed.");

//QUERY THE DATABASE
$sqlquery = "SELECT * FROM videogames";
$sqlresult = mysql_query($sqlquery,$dbconnection)
or die ("Error in executing the SQL statement");

//CREATE XML STRING
$xmlstring = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n";
$xmlstring.= "<videogames>";

while ($row = mysql_fetch_array($sqlresult))
{
    $xmlstring .= "\t<game>\r\n";
        $xmlstring .= "\t\t<gametitle>" .$row["gametitle"]. "</gametitle>\r\n";
        $xmlstring .= "\t\t<genre>" .$row["genre"]. "</genre>\r\n";
        $xmlstring .= "\t\t<year>" .$row["year"]. "</year>\r\n";
        $xmlstring .= "\t\t<platform>" .$row["platform"]. "</platform>\r\n";
        $xmlstring .= "\t\t<agerating>" .$row["agerating"]. "</agerating>\r\n";
        $xmlstring .= "\t\t<price>" .$row["price"]. "</price>\r\n";
    $xmlstring .= "\t</game>\r\n";
}

$xmlstring.= "</videogames>";

//WRITE XML STRING TO EXTERNAL FILE
$filename = "videogames.xml";
$fileaccessmode = "w";
$fptr = fopen($filename,$fileaccessmode);
fwrite($fptr,$xmlstring);
fclose($fptr);

//FREE UP MEMORY
mysql_free_result($sqlresult);
mysql_close($dbconnection);

return $xmlstring;

}

//CODE TO DISABLE THE WSDLE CACHE
ini_set("soap.wsdl_cache_enabled","0");

//DEFINE SOAP SERVER INSTANCE AND RELATED WSDL FILE
//THE service.wsdl FILE IS IN THE SAME FOLDER AS THIS server.php FILE
$server = new SoapServer("service.wsdl");

//ADD FUNCTION TO THE SERVER INSTANCE
$server->addFunction("getXML");

//ACTIVATE THE SOAP HANDLER
$server->handle();

?>

这是链接到 server.php 文件的 WSDL 文件。

<?xml version ='1.0' encoding ='UTF-8' ?>

php web service to dot net

Answer 2

你需要修复你的 wsdl：

<operation name="getXML">
    <soap:operation soapAction="urn:MyWebService#getXML"/>
   <input>
     <soap:body use="literal"/>
   </input>
   <output>
     <soap:body use="literal"/>
   </output>
</operation>

</binding>

Answer 3

在过去，我很难让 .Net 使用 rpc/literal 格式的 wsdl 创建的 Web 服务。尝试将您的 WSDL 转换为文档/文字格式，您应该会有更多的运气。
