WSDL PHP函数返回null,而其他函数返回预期结果

前端之家收集整理的这篇文章主要介绍了WSDL PHP函数返回null,而其他函数返回预期结果前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
概要

在这里,我将列出我为解决这个问题而采取的所有步骤,作为其他人的参考.

1.
PHP,愚蠢的,’侦听’功能的输入消息,以定义它应该使用什么功能.因此,即使使用相同的类型或元素,也可以给每个函数一个不同的输入消息.你可能会认为这对你来说很有帮助,但可以这样做:

<xsi:complexType name="UserCredentials">
<xsi:attribute name="customerID" type="xsi:int"/>
</xsi:complexType>

<xsi:element name="UserCredentials" type="types:UserCredentials"/>
<xsi:element name="UserCredentials1" type="types:UserCredentials"/>

<wsdl:message name="getCustomerCredentials">
 <wsdl:part name="body" element="types:UserCredentials"/>
</wsdl:message>
<wsdl:message name="getCustomerCredentials1">
<wsdl:part name="body" element="types:UserCredentials1"/>
</wsdl:message>

接下来,Visual Studio正在呜咽,我花了几天时间才明​​白这个愚蠢的愚蠢的简单的事情,只是告诉你刚刚设置对象属性的程序:

UserCredentials.customerID = User.CustomerID;
 UserCredentials.customerIDSpecified = true;

就是这样我不敢相信自己.我花了1.5个星期,解决方案是两个步骤,请给这个回答下面一些投票的人.

更新

我的输入对象不是开始解析成XML.

//固定:

你必须告诉程序该属性是这样设置的:

UserCredentials.customerID = User.CustomerID;
UserCredentials.customerIDSpecified = true;

Fiddler显示

输入

<s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">
<s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<UserCredentials2 xmlns="http://5.157.80.21/servicehandler/wsdl_service.wsdl"/>   
</s:Body>
</s:Envelope>

产量

<?xml version="1.0" encoding="UTF-8"?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="types">
<SOAP-ENV:Body>
<ns1:PersoonArray/>
</SOAP-ENV:Body>
</SOAP-ENV:E‌​nvelope>

这段代码有什么问题吗?

public static List<Klant> GetAllPersonen()
    {
        List<Klant> list = new List<Klant>();

        WeGotchaService.Persoon[] servicePersonen = dpc.getAllPersoonData(UserCredentials);

        foreach (WeGotchaService.Persoon p in servicePersonen)
        {
            Klant k = new Klant(p);
            list.Add(k);
        }

        return list;
    }

更新到以下评论

<xsi:complexType name="UserCredentials">
        <xsi:attribute name="customerID" type="xsi:int"/>       
    </xsi:complexType>
        <xsi:element name="UserCredentials" type="tns:UserCredentials" />
        <xsi:element name="UserCredentials2" type="tns:UserCredentials"/>

 <wsdl:message name="getCustomerCredentials">
    <wsdl:part name="body" element="ns:UserCredentials"/>
</wsdl:message>
<wsdl:message name="getCustomerCredentials2">
    <wsdl:part name="body" element="ns:UserCredentials2"/>
</wsdl:message>

    <wsdl:operation name="getAllLessenData">
        <wsdl:input message="ns:getCustomerCredentials"/>
        <wsdl:output message="ns2:LessenList"/>
    </wsdl:operation>
    <wsdl:operation name="getAllPersoonData">
        <wsdl:input message="ns:getCustomerCredentials2"/>
        <wsdl:output message="ns3:PersoonList"/>
    </wsdl:operation>

这似乎起作用,除了它现在在VS10中返回一个count = 0数组

另一个更新

评论中有人发布了一个linkPHP错误报告.第二个评论者声称,他通过将所有的消息删除放在其他文件中,并将它们包含在这个主要的WSDL文档中,围绕着这个同样的问题.我试过这个,但是没有起作用,没有改变.

更新:

所以我改变了绑定方法中定义的函数的顺序,并且找出以下结果:只有在绑定区域中定义的第一个函数才有效,所以在这种情况下,只有我的getAllLessenData有效,因为我把它放在所有其他方面.有人看到错误吗?

<wsdl:binding name="DataBinding" type="tns:DataPort">
    <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
    <wsdl:operation name="getAllLessenData">

        <wsdl:input>
            <soap:body use="literal"/>
        </wsdl:input>
        <wsdl:output>
            <soap:body use="literal"/>

            <soap:body use="literal"/>
        </wsdl:output>
    </wsdl:operation>
</wsdl:binding>

更新结束

我对WSLD有一点问题(再次)

我的getAllLessenData(和其他函数)都返回NULL,而一个函数(getAllPersoonData)返回预期的.

我的数据库中有行,直接从我的servicehandler.PHP调用getAllLessenData(1)返回预期的结果.然而,在我的test.PHP中,它只返回NULL,getLastResponse返回getAllPersoonData(1)的结果.

对于我来说,这两个功能的防守看起来都一样,我复制粘贴了大部分.我尝试改变命名空间等google.但它没有奏效.有任何想法吗?

如果您需要更多信息,请回复.

编辑1:这也可能与getAllPersoonData和getAllLessenData具有相同的输入签名的事实有关,这意味着对于文档文字风格的Web服务,端点将无法区分您实际使用哪种请求制造.尝试传递两个不同的元素名称.

编辑2:此外,给这些消息不同的签名将允许您将getPersoonID放在类型定义中,以便您只有一个消息部分.现在,如果你看到Customer.wsdl你有:

<wsdl:message name="getPersoonIDCustomerID">
    <wsdl:part name="body" element="ns:UserCredentials"/>
    <wsdl:part name="getPersoonID" type="xs:int"/>
</wsdl:message>

您不应该在文档文字消息中有多个部分.

编辑3:如果您不想为每个功能定义一个新元素,那么您将必须切换到RPC文字,该文本将请求包装在wsdl:操作名称中.如果这将修复除.NET以外的所有内容,那么您可以尝试我的SO帖子哄骗.NET阅读RPC文字Web服务.
