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

C# 调用Java的WebService的3种方式

 

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:

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

C# 调用Java的WebService的3种方式

 

 

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,

C# 调用Java的WebService的3种方式

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 { setget; }

 

 

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

 

C# 调用Java的WebService的3种方式

 

 

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

 

C# 调用Java的WebService的3种方式

 

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 Files\Microsoft Visual Studio 12.0\WS.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:   C# 调用Java的WebService的3种方式     默认生成的SOAP版本为1.1,可以

G:\Program Files\Microsoft 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。
