asp.net – 如何在WCF中使用SOAP :: Lite？

发布时间：2020-12-16 09:47:58 所属栏目：asp.Net 来源：网络整理
导读：我只是想开始使用WCF.听起来它应该是超级简单的,但使用像SOAP :: Lite这样的简单API,我无法使任何工作. googlesphere中有很多过时的例子,我尝试了很多这些例子都无济于事.所以现在我试图将问题分解到最低水平.我创建了由Visual Web Developer 2008 Express模
我只是想开始使用WCF.听起来它应该是超级简单的,但使用像SOAP :: Lite这样的简单API,我无法使任何工作. googlesphere中有很多过时的例子,我尝试了很多这些例子都无济于事.所以现在我试图将问题分解到最低水平.我创建了由Visual Web Developer 2008 Express模板生成的WCF应用程序.这是它的服务合同： 

[ServiceContract]
public interface IService1
{

    [OperationContract]
    string GetData(int value);

    [OperationContract]
    CompositeType GetDataUsingDataContract(CompositeType composite);

    // TODO: Add your service operations here
}


// Use a data contract as illustrated in the sample below to add composite types to service operations.
[DataContract]
public class CompositeType
{
    bool boolValue = true;
    string stringValue = "Hello ";

    [DataMember]
    public bool BoolValue
    {
        get { return boolValue; }
        set { boolValue = value; }
    }

    [DataMember]
    public string StringValue
    {
        get { return stringValue; }
        set { stringValue = value; }
    }
}

我在调试模式下启动它并试图联系.使用调试URL http：// localhost：59315 / Service1.svc使用浏览器这样做会给我一个页面说明：

You have created a service.

To test this service,you will need to create a client and use it to
call the service. You can do this using the svcutil.exe tool from the
command line with the following syntax:

svcutil.exe http://localhost:59315/Service1.svc?wsdl

所以,然后我浏览了那个wsdl并得到了这个：

<wsdl:definitions name="Service1" targetNamespace="http://tempuri.org/">

没有什么太疯狂了(除了SOAP本身)…无论如何,现在我尝试一个简单的SOAP :: Lite应用程序：

#!/cygdrive/C/Perl64/bin/perl.exe -w

use strict;
use warnings;

use Data::Dumper;
use SOAP::Lite +trace => [ transport => sub {
    my ($in) = @_;
    if ( ref($in) eq "HTTP::Request") {
        print( "REQUESTn" . $in->content() . "nEND REQUESTn" );
    } 
    elsif ( ref($in) eq "HTTP::Response") {
        print( "RESPONSEn" . $in->content() . "nEND RESPONSEn" );
    }
} ];


my $server = 'http://localhost:59315/Service1.svc';
my $url = "$server?wsdl";
my $xmlns = 'http://schemas.datacontract.org/2004/07/RossDominosService';

# Setup Network Connection
my $service = SOAP::Lite
    ->ns( $url )
    ->proxy( $server )
    ->on_fault( sub {
        my ($soap,$res) = @_;
        die ref $res ? $res->faultstring() : $soap->transport()->status(),"n";
    } );
;

print( Dumper( $service ) );

eval {
    print( "making requestn" );
    my $response = $service->GetData( 
        SOAP::Data->new( name => 'value',value => 5 ) 
    );
    print( "got response:n$responsen" );
};
if ( $@ ) {
    print( "failed:n**************************n$@n*****************************n" );
}

调试中的哪个是发出此SOAP请求：

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:namesp1="http://localhost:59315/Service1.svc?wsdl" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <namesp1:GetData>
      <value xsi:type="xsd:int">5</value>
    </namesp1:GetData>
  </soap:Body>
</soap:Envelope>

但回应是：

failed:
**************************
415 Unsupported Media Type

*****************************

到底是怎么回事？这就是“Hello,World！” SOAP应用程序,我无法弄明白.

———————– UPDATE ————————– —–

我发现我需要将绑定从其默认的wsHttpBinding更改为：

<endpoint address="" binding="basicHttpBinding" 
              contract="RossDominosService.IService1">

现在它似乎连接,但我收到这个新错误：

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
  <s:Body>
    <s:Fault>
      <faultcode xmlns:a="http://schemas.microsoft.com/ws/2005/05/addressing/none">a:ActionNotSupported</faultcode>
      <faultstring xml:lang="en-US">The message with Action 'http://tempuri.org/GetData' cannot be processed at the receiver,due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver.  Check that sender and receiver have the same contract and the same binding (including security requirements,e.g. Message,Transport,None).</faultstring>
    </s:Fault>
  </s:Body>
</s:Envelope>

这似乎不应该这么难……

———————– UPDATE ————————– —–

得到它了！经过一些修修补补,以及soapUI的一些帮助,我发现需要修改动作,以便：

<namespace>/<serviceContract>/<method>

在这种情况下：

http://tempuri.org/IService1/GetData

使用SOAP :: Lite时,默认的SOAPAction是

<namespace>#<method>

所以你必须这样修改你的soap对象：

$soap->on_action( sub { sprintf( '%sIService1/%s',@_ ) } );

我会写下面的答案,所以我们可以关闭这个问题……

解决方法

这就是我使用perl SOAP :: Lite客户端启动和运行WCF Web服务的方法.请注意,我使用Visual Web Developer Express 2008和perl 5.14与SOAP :: Lite 0.715.

>打开Visual Web Developer
>文件 – >新项目…

> Visual C# – >卷筒纸
> WCF服务应用程序
>名称：WcfService1
>地点：
>解决方案：新解决方案
>解决方案名称：

>打开Web.config

>更改< compilation debug =“false”> to< compilation debug =“true”>
> change< endpoint address =“”binding =“wsHttpBinding”contract =“WcfService1.IService1”> to< endpoint address =“”binding =“basicHttpBinding”contract =“WcfService1.IService1”>

>打开Service1.svc.cs

>按f5(开始调试)

现在应该弹出一个浏览器窗口打开到您的服务页面.记下网址中的端口,您将需要它为客户端.然后创建此脚本：

#!/cygdrive/C/Perl64/bin/perl.exe -w

use strict;
use warnings;

use Data::Dumper;
use SOAP::Lite +trace => [ transport => sub {
    my ($in) = @_;
    if ( ref($in) eq "HTTP::Request") {
        print( "**** REQUEST ****n" . $in->content() . "n**** END REQUEST ****n" );
    } 
    elsif ( ref($in) eq "HTTP::Response") {
        print( "**** RESPONSE ****n" . $in->content() . "n**** END RESPONSE ****n" );
    }
} ];

my $port = 63181;
my $server = "http://localhost:$port/Service1.svc";
my $namespace = 'http://tempuri.org/';

# Setup Network Connection
my $service = SOAP::Lite
    ->ns( $namespace,'my' )
    ->proxy( $server )
    ->on_action( sub { 
        my $action = sprintf( '%sIService1/%s',@_ );
        print( "action: '$action'n" ); 
        return $action;
    } );

print( Dumper( $service ) );

eval {
    print( "making requestn" );
    my $response = $service->GetData( 
        SOAP::Data->new( prefix => 'my',name => 'value',value => 5 ) 
    );
    print( "got response:n$responsen" );
};
if ( $@ ) {
    print( "failed:n**************************n$@n*****************************n" );
}

您需要更改端口号以匹配您的端口号.另外,我留下了一堆调试代码,这样你就可以看到发生了什么.

我希望这有助于其他人.
