Web服务软件工厂（WSSF）演练之四：创建简单的客户端，测试呼叫服务
关键字:Web Services Software Factory, Simple Client, Call Service
这是本系列教程的第五部分。如果您需要阅读之前的部分可以单击这里。我们已经建立了一个Web服务，它通过散列对字符串进行一些简单的加密和解密。在开始这部分的演练之前，请在IIS中创建一个虚拟目录，指向我们在第四部分创建的Web服务的项目，这里命名为虚拟目录CryptService ，因此我可以浏览到http://localhost/CryptService/CryptService.svc和看到的服务。
创建一个新的C ＃控制台应用程序。我本人命名的应用TestCryptService 。右键单击您的项目在解决方案资源管理器，然后选择“Add Service Reference”（添加服务引用） 。在添加服务引用窗口中，将您的服务地址添加到地址栏中，本演练中我添加的是http://localhost/CryptService/CryptService.svc并单击Go（前往）按钮 。过了几分钟，你应该看看发现您服务。改变命名空间CryptService ，然后单击确定。
请注意，所有的绑定信息已添加到您的app.config文件中 。如果你查看一下这个文件，Endpoint节中，您将看binding="basicHttpBinding" indingConfiguration="Crypt" 。我提到的最后一次，您可以创建多个Endpoints（端点）使用不同的绑定方式进行绑定。
1. <?xml version="1.0" encoding="utf-8" ?>
2. <CONFIGURATION>
3. <SYSTEM.SERVICEMODEL>
4. <BINDINGS>
5. <BASICHTTPBINDING>
6. <BINDING name="Crypt" useDefaultWebProxy="true" transferMode="Buffered" textEncoding="utf-8" messageEncoding="Text" maxReceivedMessageSize="65536" maxBufferPoolSize="524288" maxBufferSize="65536" hostNameComparisonMode="StrongWildcard" bypassProxyOnLocal="false" allowCookies="false" sendTimeout="00:01:00" receiveTimeout="00:10:00" openTimeout="00:01:00" closeTimeout="00:01:00">
7. <READERQUOTAS maxNameTableCharCount="16384" maxBytesPerRead="4096" maxArrayLength="16384" maxStringContentLength="8192" maxDepth="32" />
8. <SECURITY mode="None">
9. <TRANSPORT realm="" proxyCredentialType="None" clientCredentialType="None" />
10. <MESSAGE clientCredentialType="UserName" algorithmSuite="Default" />
11. </SECURITY>
12. </BINDING>
13. </BASICHTTPBINDING>
14. </BINDINGS>
15. <CLIENT>
16. <ENDPOINT name="Crypt" contract="CryptService.CryptService" bindingConfiguration="Crypt" binding="basicHttpBinding" address="http://localhost/CryptService/CryptService.svc/basic" />
17. </CLIENT>
18. </SYSTEM.SERVICEMODEL>
19. </CONFIGURATION>
现在，打开Program.cs文件，输入以下代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using TestCryptService.CryptService;
namespace TestCryptService
{
class Program
{
static void Main(string[] args)
{
TestDesEncryption();
TestRijndaelEncryption();
TestMd5Hash();
TestSha256Hash();
}
/// <SUMMARY>
/// This method is the only one that is commented. All of the other methods function
/// in exactly the same way. The only reason they are included is for completeness,
/// so that all of our server methods are hit.
/// </SUMMARY>
static void TestDesEncryption()
{
// The CryptServiceClient is the proxy created automatically for you.
// It would be called CryptServiceClient whether you used svcutil.exe
// yourself or you added a service reference.
CryptServiceClient client = new CryptServiceClient();
EncryptionObject encryptionObject = new EncryptionObject();
encryptionObject.EncryptionAlgorithm = EncryptionAlgorithm.DES;
encryptionObject.Text = "Testing our DES Encryption";
// Call the EncryptString method and get back our encrypted value
string encryptedText = client.EncryptString(encryptionObject);
encryptionObject = new EncryptionObject();
encryptionObject.EncryptionAlgorithm = EncryptionAlgorithm.DES;
encryptionObject.Text = encryptedText;
// Call the DecryptString method and get back our plain text
string plainText = client.DecryptString(encryptionObject);
// Output the values and see what we get.
Console.WriteLine("-- DES --");
Console.WriteLine("Encrypted Text: {0}", encryptedText);
Console.WriteLine("Plain Text: {0}", plainText);
Console.WriteLine();
}
static void TestRijndaelEncryption()
{
CryptServiceClient client = new CryptServiceClient();
EncryptionObject encryptionObject = new EncryptionObject();
encryptionObject.EncryptionAlgorithm = EncryptionAlgorithm.Rijndael;
encryptionObject.Text = "Testing our Rijndael Encryption";
string encryptedText = client.EncryptString(encryptionObject);
encryptionObject = new EncryptionObject();
encryptionObject.EncryptionAlgorithm = EncryptionAlgorithm.Rijndael;
encryptionObject.Text = encryptedText;
string plainText = client.DecryptString(encryptionObject);
Console.WriteLine("-- Rijndael --");
Console.WriteLine("Encrypted Text: {0}", encryptedText);
Console.WriteLine("Plain Text: {0}", plainText);
Console.WriteLine();
}
static void TestMd5Hash()
{
CryptServiceClient client = new CryptServiceClient();
HashObject hashObject = new HashObject();
hashObject.HashType = HashType.MD5;
hashObject.StringToHash = "Some string to hash";
string md5Hash = client.HashString(hashObject);
Console.WriteLine("-- MD5 Hash --");
Console.WriteLine("Original String: {0}", hashObject.StringToHash);
Console.WriteLine("Hashed Value: {0}", md5Hash);
Console.WriteLine();
}
static void TestSha256Hash()
{
CryptServiceClient client = new CryptServiceClient();
HashObject hashObject = new HashObject();
hashObject.HashType = HashType.SHA256;
hashObject.StringToHash = "Some string to hash";
string shaHash = client.HashString(hashObject);
Console.WriteLine("-- Sha256 Hash --");
Console.WriteLine("Original String: {0}", hashObject.StringToHash);
Console.WriteLine("Hashed Value: {0}", shaHash);
Console.WriteLine();
}
}
}
当我运行此代码，看到如下的输出：
如果您已经看到了输出结果,那么恭喜你,您已经掌握了使用WSSF创建Web Service的一般过程和步骤,您已经创建了一个可以使用的Web服务软件工厂，并且可以在此基础上进一步扩展此服务的功能。如果您没有看到正确的输出结果，请仔细检查您的步骤，如果您仍遇到问题，可以在这里提出您的问题，我将尽力为您提供帮助。
以上所有代码为了演练而被写为一次性代码，所以它们应该使用一些重构和一些优化才完美。本教程是您用WSSF创建“Hello World”的一种方式，欢迎大家提出您的观点，我们一起讨论。
