在WCF中使用REST时，如何去掉URL中的.svc后缀

以Windows 7里面的IIS7.5为例。

假设我们的service method样子为

 

<WebGet(UriTemplate:="{parameter}")> _
        <OperationContract()> _
        Function ServiceMethod(ByVal parameter As String) As Boolean

 

我们希望将一个这样的url

http://localhost/SomeService/ServiceMethod.svc/Parameter

使用

 

 

http://localhost/SomeService/ServiceProvider/Parameter

来访问

 

首先从这里安装一个URLRewrite。

 安装后打开IIS，从Features View里面可以看到URL Rewrite设置图标。

 

 双击进入设置，选择Add Rule(s)...然后选择Blank Rule

进行如下设置

 

Fill out the form with the following data (we will describe the patterns in detail in a moment):

1. Name:                       RemoveSvcExtension (or any name you want)
2. Requested URL:         Matches the pattern
3. Using:                       Regular Expressions
4. Pattern:                    ^([0-9a-zA-Z\-]+)/([0-9a-zA-Z\-\.\/\(\)]+)
5. Ignore Case:             Checked
6. Action Type:              Rewrite
7. Rewrite URL:             {R:1}.svc/{R:2}
8. Append QueryString   Checked

 

 

 稍微解释一下Regex Pattern的含义。

 

• The "^" indicates the beginning of the line or string
• The parenthesis "()" allow you to define a numbered capture group, meaning that you can reference everything inside the parens later by index.  In our example, we have 2 numbered capture groups 1 and 2.  You refer back to these later with the syntax: {R:1} and {R:2}
• The pattern [0-9a-zA-Z\-]+ indicates any character in 0-9, lowercase a-z, uppercase A-Z or "-", one or more repetitions.
• The / is a straight match to a slash "/".  In other words, the first named capture group will capture 0-9,a-z, A-Z and "-" prior to the first "/" and you will be able to reference them with {R:1}
• Then we have another named capture group
• The pattern [0-9a-zA-Z\-\.\/\(\)] matches any character in 0-9, lowercase a-z, uppercase A-Z or "-", ".", "/", "(", ")", one or more repetitions.
