给定一个 Uri 和一个 UriTemplate，如何获取模板参数值？

发布于 2024-12-06 09:46:31 字数 659 浏览 0 评论 0原文

如果我可以访问 Uri 及其所基于的 UriTemplate，那么发现已替换模板中参数的值的最简洁方法是什么？

例如，如果我知道：

        var uriTemplate = new UriTemplate("/product-catalogue/categories/{categoryName}/products/{product-name}");
        var uri = new Uri("/product-catalogue/categories/foo/products/bar");

是否有一种内置方法可以让我发现categoryName =“foo”和productName =“bar”？

我希望找到这样的方法：

        var parameterValues = uriTemplate.GetParameterValues(uri);

其中parameterValues将是：

         { { "categoryName", "foo" }, { "productName", "bar" }}

显然，我可以编写自己的方法，但我想知道框架中是否有我可以使用的东西。

谢谢桑迪

原文

If I have access to both a Uri and the UriTemplate on which is is based, what is the neatest way to discover the values that have replaced the parameters in the template?

For example, if I know:

        var uriTemplate = new UriTemplate("/product-catalogue/categories/{categoryName}/products/{product-name}");
        var uri = new Uri("/product-catalogue/categories/foo/products/bar");

is there a built-in way for me to discover that categoryName = "foo" and productName = "bar"?

I was hoping to find a method like:

        var parameterValues = uriTemplate.GetParameterValues(uri);

where parameterValues would be:

         { { "categoryName", "foo" }, { "productName", "bar" }}

Clearly, I could write my own, but I was wondering if there was something in framework I could use.

Thanks

您可以在 上调用 Match 方法uriTemplate 实例并使用返回的 UriTemplateMatch 实例访问参数值：

var uriTemplate = new UriTemplate("/product-catalogue/categories/{categoryName}/products/{product-name}"); 
var uri = new Uri("http://www.localhost/product-catalogue/categories/foo/products/bar"); 
var baseUri = new Uri("http://www.localhost");

var match = uriTemplate.Match(baseUri, uri);

foreach (string variableName in match.BoundVariables.Keys)
{
    Console.WriteLine("{0}: {1}", variableName, match.BoundVariables[variableName]);
}

输出

CATEGORYNAME: foo
PRODUCT-NAME: bar

You can call the Match method on the uriTemplate instance and use the returned UriTemplateMatch instance to access the parameter values:

var uriTemplate = new UriTemplate("/product-catalogue/categories/{categoryName}/products/{product-name}"); 
var uri = new Uri("http://www.localhost/product-catalogue/categories/foo/products/bar"); 
var baseUri = new Uri("http://www.localhost");

var match = uriTemplate.Match(baseUri, uri);

foreach (string variableName in match.BoundVariables.Keys)
{
    Console.WriteLine("{0}: {1}", variableName, match.BoundVariables[variableName]);
}

outputs
