Asp.net mvc 在.NETMVC3中使用RESTWeb服务
我正在开发一个.NET4MVC3应用程序。我试图遵循领域驱动的设计范式。现在，我的应用程序分为两部分，一部分是域，另一部分是用于web的MVC代码。我希望得到一些帮助，以确定在这个结构中应该在何处使用RESTful web服务 这个特定的项目使用RESTfulWeb服务来检索和持久化数据。在我的域中，我有两个实体“Customer”和“User”，它们与同名的web服务配对。e、 g.URL/客户和URL/用户。每个web服务接受一些参数，然后以XML格式返回适当的数据列表。我需要以（POST、GET、PUT和DELETE）的形式实现基本的CRUD功能。鉴于此，我有两个主要问题 1.）我应该创建什么类型的对象来使用这些web服务？我的直觉是创建一个定义CRUD操作的ICCustomerService接口，然后以使用HTTPWebConnection（或扩展它？）的类的形式创建该接口的实现。有没有更好的方法来使用RESTful web服务？这种类型的类应该是静态的吗 2.）此服务代码应该放在哪里？同样，我的直觉告诉我，除了代码中的域和WebUI部分之外，我还需要第三个服务部分，其中包含这些web服务客户端的接口和实现，但是由于web服务返回的是我域中的客户和用户实体的XML表示，这些服务不会真正从域中解耦 提前感谢,， 格雷格 编辑 在从事各种项目一段时间后，我发现了一种在MVC中处理RESTWeb服务的好方法 首先，我创建表示我将使用的各种web服务的实体。每个实体使用XML属性将属性与XML元素匹配。下面是一个简单的例子，假设一个web服务返回关于人们及其衬衫的信息（这很愚蠢，但我能马上想出最好的方法） 假设我从web服务获取一个Person对象。这里是XMLAsp.net mvc 在.NETMVC3中使用RESTWeb服务,asp.net-mvc,rest,.net-4.0,dns,domain-driven-design,Asp.net Mvc,Rest,.net 4.0,Dns,Domain Driven Design,我正在开发一个.NET4MVC3应用程序。我试图遵循领域驱动的设计范式。现在，我的应用程序分为两部分，一部分是域，另一部分是用于web的MVC代码。我希望得到一些帮助，以确定在这个结构中应该在何处使用RESTful web服务 这个特定的项目使用RESTfulWeb服务来检索和持久化数据。在我的域中，我有两个实体“Customer”和“User”，它们与同名的web服务配对。e、 g.URL/客户和URL/用户。每个web服务接受一些参数，然后以XML格式返回适当的数据列表。我需要以（POST、
