C# 调用Java的WebService的3种方式

C# 调用WebService的3种方式 :直接调用、根据wsdl生成webservice的.cs文件及生成dll调用、动态调用

 

 关于soapheader调用，可以参考

C#调用Java的WebService添加SOAPHeader验证

1.问题描述

调用的Java的webservice

string Invoke(string func, string reqXml)

　使用C#直接调用一直报错。

webservice提供方有说明如下：

1 2 3 4 5 6 7 8 9 10 11 12 13

身份验证采用对SOAP身份认证(用户名/密码验证/序列号)的方式部署，设定用户名和密码由系统配置，所有文本内容编码选择UTF-8编码规范 <?xml version='1.0' encoding='utf-8'?> <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Header> <vc:Authentication xmlns: vc ="http://ant.com"> <vc:Username>[系统配置] </vc:Username> <vc:Password>[系统配置]</vc:Password> <vc:SerialNo>[系统配置]</vc:SerialNo > </vc:Authentication> </soapenv:Header> <soapenv:Body> </soapenv:Body> </soapenv:Envelope>

相信就是soapenv:Header这里的问题了，C# 没soapenv:Header这些东西的

网上查了好多类似下面的

https://www.cnblogs.com/o2ds/p/4093413.html

C#访问Java的WebService添加SOAPHeader验证的问题

都没有用

后来尝试sopui及xmlspy创建soap，直接发送xml，终于试出来了，然后C#使用http post调用webservice，成功了。

2.问题解决1

C#拼接的需要http post的soap字符串如下

</SOAP-ENV:Header> 照搬给的文档里的字符串

<SOAP-ENV:Body> 为调用函数，string Invoke(string func, string reqXml) 函数名Invoke，两个参数，自行理解吧

注意：里面的
换行标志都要保留，不然都是报错

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

string soap = "<?xml version="1.0" encoding="utf-8"?> " +                "<SOAP-ENV:Envelope " +                "xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" " +                "xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" " +                "xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" " +                "xmlns:xsd="http://www.w3.org/2001/XMLSchema"> " +                "<SOAP-ENV:Header> " +                    "<vc:Authentication " +                        "xmlns:vc="http://ant.com"> " +                        "<vc:Username>xx</vc:Username> " +                        "<vc:Password>xxx</vc:Password> " +                        "<vc:SerialNo>xxxx</vc:SerialNo> " +                    "</vc:Authentication> " +                "</SOAP-ENV:Header> " +                "<SOAP-ENV:Body> " +                    "<m:Invoke " +                        "xmlns:m="http://tempuri.org/"> " +                        "<m:func>" + jkid + "</m:func> " +                        "<m:reqXml>" + HttpUtility.HtmlEncode(xml) + "</m:reqXml> " +                    "</m:Invoke> " +                "</SOAP-ENV:Body> " +                "</SOAP-ENV:Envelope>";

　　然后发送，随便找个http post的代码就行了

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28

public static string GetSOAPReSource(string url, string datastr)        {            try            {                //request                Uri uri = new Uri(url);                WebRequest webRequest = WebRequest.Create(uri);                webRequest.ContentType = "text/xml; charset=utf-8";                  webRequest.Method = "POST";                using (Stream requestStream = webRequest.GetRequestStream())                {                    byte[] paramBytes = Encoding.UTF8.GetBytes(datastr.ToString());                    requestStream.Write(paramBytes, 0, paramBytes.Length);                }                //response                WebResponse webResponse = webRequest.GetResponse();                using (StreamReader myStreamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8))                {                    string result = "";                    return result = myStreamReader.ReadToEnd();                }            }            catch (Exception ex)            {                throw ex;            }        }

　　

3.问题解决2

发现还是报错，http 500错误，和之前不一样，但依然不对

研究webservice的wsdl发现了问题

调用时加上

1	<strong>webRequest.Headers.Add("SOAPAction", "http://tempuri.org/IAjsjService/Invoke");<br><br></strong>终于成功了

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29

public static string GetSOAPReSource(string url, string datastr)        {            try            {                //request                Uri uri = new Uri(url);                WebRequest webRequest = WebRequest.Create(uri);                webRequest.ContentType = "text/xml; charset=utf-8";                webRequest.Headers.Add("SOAPAction", "http://tempuri.org/IAjsjService/Invoke");                  webRequest.Method = "POST";                using (Stream requestStream = webRequest.GetRequestStream())                {                    byte[] paramBytes = Encoding.UTF8.GetBytes(datastr.ToString());                    requestStream.Write(paramBytes, 0, paramBytes.Length);                }                //response                WebResponse webResponse = webRequest.GetResponse();                using (StreamReader myStreamReader = new StreamReader(webResponse.GetResponseStream(), Encoding.UTF8))                {                    string result = "";                    return result = myStreamReader.ReadToEnd();                }            }            catch (Exception ex)            {                throw ex;            }        }

　　

其他调用webservice的方式：

上一篇链接如上，更像是 Net下采用GET/POST/SOAP方式动态调用WebService的简易灵活方法(C#) 来处理xml，解决复杂的认证

又遇到一家

身份验证采用对SOAP身份认证(用户名/密码验证/序列号)的方式部署，设定用户名和密码由系统配置，所有文本内容编码选择UTF-8编码规范
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
<soapenv:Header>
<vc:Authentication xmlns: vc ="http://ant.com">
<vc:Username>[系统配置] </vc:Username>
<vc:Password>[系统配置]</vc:Password>
<vc:SerialNo>[系统配置]</vc:SerialNo >
</vc:Authentication>
</soapenv:Header>
<soapenv:Body>
</soapenv:Body>
</soapenv:Envelope> 

wsdl的xml如下

<?xml version="1.0" encoding="utf-8"?><wsdl:definitions name="AjsjService" targetNamespace="http://tempuri.org/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soap12="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:tns="http://tempuri.org/" xmlns:wsa="http://schemas.xmlsoap.org/ws/2004/08/addressing" xmlns:wsx="http://schemas.xmlsoap.org/ws/2004/09/mex" xmlns:wsap="http://schemas.xmlsoap.org/ws/2004/08/addressing/policy" xmlns:wsaw="http://www.w3.org/2006/05/addressing/wsdl" xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract" xmlns:wsp="http://schemas.xmlsoap.org/ws/2004/09/policy" xmlns:wsa10="http://www.w3.org/2005/08/addressing" xmlns:wsam="http://www.w3.org/2007/05/addressing/metadata"><wsdl:types><xsd:schema targetNamespace="http://tempuri.org/Imports"><xsd:import schemaLocation="vehcheck0.xml" namespace="http://tempuri.org/"/><xsd:import schemaLocation="vehcheck1.xml" namespace="http://schemas.microsoft.com/2003/10/Serialization/"/></xsd:schema></wsdl:types><wsdl:message name="IAjsjService_Invoke_InputMessage"><wsdl:part name="parameters" element="tns:Invoke"/></wsdl:message><wsdl:message name="IAjsjService_Invoke_OutputMessage"><wsdl:part name="parameters" element="tns:InvokeResponse"/></wsdl:message><wsdl:message name="IAjsjService_TrffpnCall_InputMessage"><wsdl:part name="parameters" element="tns:TrffpnCall"/></wsdl:message><wsdl:message name="IAjsjService_TrffpnCall_OutputMessage"><wsdl:part name="parameters" element="tns:TrffpnCallResponse"/></wsdl:message><wsdl:portType name="IAjsjService"><wsdl:operation name="Invoke"><wsdl:input wsaw:Action="http://tempuri.org/IAjsjService/Invoke" message="tns:IAjsjService_Invoke_InputMessage"/><wsdl:output wsaw:Action="http://tempuri.org/IAjsjService/InvokeResponse" message="tns:IAjsjService_Invoke_OutputMessage"/></wsdl:operation><wsdl:operation name="TrffpnCall"><wsdl:input wsaw:Action="http://tempuri.org/IAjsjService/TrffpnCall" message="tns:IAjsjService_TrffpnCall_InputMessage"/><wsdl:output wsaw:Action="http://tempuri.org/IAjsjService/TrffpnCallResponse" message="tns:IAjsjService_TrffpnCall_OutputMessage"/></wsdl:operation></wsdl:portType><wsdl:binding name="BasicHttpBinding_IAjsjService" type="tns:IAjsjService"><soap:binding transport="http://schemas.xmlsoap.org/soap/http"/><wsdl:operation name="Invoke"><soap:operation soapAction="http://tempuri.org/IAjsjService/Invoke" style="document"/><wsdl:input><soap:body use="literal"/></wsdl:input><wsdl:output><soap:body use="literal"/></wsdl:output></wsdl:operation><wsdl:operation name="TrffpnCall"><soap:operation soapAction="http://tempuri.org/IAjsjService/TrffpnCall" style="document"/><wsdl:input><soap:body use="literal"/></wsdl:input><wsdl:output><soap:body use="literal"/></wsdl:output></wsdl:operation></wsdl:binding><wsdl:service name="AjsjService"><wsdl:port name="BasicHttpBinding_IAjsjService" binding="tns:BasicHttpBinding_IAjsjService"><soap:address location="http://ip:8000/v"/></wsdl:port></wsdl:service></wsdl:definitions>

使用添加服务引用加到项目里

不要用高级那里的添加web引用添加，不然后面没法做

    [System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
    [System.ServiceModel.ServiceContractAttribute(ConfigurationName="V.IAjsjService")]
    public interface IAjsjService {
        
        [System.ServiceModel.OperationContractAttribute(Action="http://tempuri.org/IAjsjService/Invoke", ReplyAction="http://tempuri.org/IAjsjService/InvokeResponse")]

    public partial class AjsjServiceClient : System.ServiceModel.ClientBase<v.IAjsjService>, v.IAjsjService {
        
        public AjsjServiceClient() {
        }
        
        public AjsjServiceClient(string endpointConfigurationName) : 
                base(endpointConfigurationName) {
        }
        
        public AjsjServiceClient(string endpointConfigurationName, string remoteAddress) : 
                base(endpointConfigurationName, remoteAddress) {
        }
        
        public AjsjServiceClient(string endpointConfigurationName, System.ServiceModel.EndpointAddress remoteAddress) : 
                base(endpointConfigurationName, remoteAddress) {
        }
        
        public AjsjServiceClient(System.ServiceModel.Channels.Binding binding, System.ServiceModel.EndpointAddress remoteAddress) : 
                base(binding, remoteAddress) {
        }
        
        public string Invoke(string func, string reqXml) {
            return base.Channel.Invoke(func, reqXml);
        }
    }
}

调用方法：

定义soapheader

public class MySoapHeader
    {
        string username;//用户名
        string password;//密码
        string serialNo;//序列号

        public MySoapHeader()
        { }

        public MySoapHeader(string u, string p, string s)
        {
            Username = u;
            Password = p;
            SerialNo = s;
        }

        public string Username
        {
            get { return username; }
            set { username = value; }
        }

        public string Password
        {
            get { return password; }
            set { password = value; }
        }
        public string SerialNo
        {
            get { return serialNo; }
            set { serialNo = value; }
        }

    }

调用

MySoapHeader myHeader = new MySoapHeader(m_user, m_pw, m_serial);

            ServiceReference.AjsjServiceClient client = new ServiceReference.AjsjServiceClient("BasicHttpBinding_IAjsjService", m_serverUrl);
            using (OperationContextScope scope = new OperationContextScope(client.InnerChannel))
            {
               
               MessageHeader header = MessageHeader.CreateHeader("Authentication", "http://ant.com", myHeader);
                OperationContext.Current.OutgoingMessageHeaders.Add(header);
                client.Invoke(func, strXml);
               

1.直接调用

已知webservice路径，则可以直接 添加服务引用--高级--添加web引用 直接输入webservice URL。这个比较常见也很简单

即有完整的webservice文件目录如下图所示，

也可以在本地IIS根据webservice文件目录新发布一个webservice，然后程序动态调用，修改Url

1	public new string Url { set; get; }

2.根据wsdl文件生成webservice 的.cs文件 及 生成dll C#调用  

有时没有这么多文件，只有wsdl文件

wsdl文件可以有别人提供或者根据webservice地址获取：

http://localhost:8888/WS.asmx?wsdl

Visual Studio 2013－>Visual Studio Tools－>VS2013 开发人员命令提示

命令行输入

wsdl E:WS.wsdl /out:WS.cs

 

E:WS.wsdl  是wsdl文件存储路径，也可以是http://localhost:8888/WS.asmx?wsdl

 

不报错的话，看路径下 Program FilesMicrosoft Visual Studio 12.0WS.cs已经自动生成

 

.cs文件看函数声明，结构体等都非常方便

 

然后命令行执行

csc /t:library WS.cs

 

同样的路径下，生成了WS.dll，拷贝出去放到项目文件夹下，C# winform程序也可以添加引用了。

 

生成的文件默认在这里：

 

 

 

默认生成的SOAP版本为1.1，可以

G:Program FilesMicrosoft Visual Studio 12.0>wsdl E:e.wsdl /protocol:SOAP12 /out:e.cs

来指定1.2

 

 

3.C# 动态调用WebService  

在C#程序中，若要调用WebService,一般是采用"添加Web引用"的方式来实现的。但如果此WebService的URL是在程序运行过程中才能获得的，那怎么办呢？那就必须是"动态"调用这个WebService了。

 

举个使用它的例子：

 object[] args = new object[1];  
 args.SetValue("cyy_JS", 0);             
DataTable dt = WebServiceHelper.InvokeWebService("http://192.168.0.10/DBMS_CYY/DBMS_Service.asmx", "GetUserTreeListData", args) as DataTable;  

 

恩~有点麻烦，这意味着每次我都要把想调用的函数的参数组织成一个object[]才行，且每次调用InvokeWebService都是在内存中创建动态程序集，效率极低。则次种方法绝对没有直接用“实例名.方法名(参数列表)”来的舒服。

 

我把它放到一个叫WebServiceHelper.cs的类里面了。
