在Winform,Silvelight,WPF等程序中访问Asp.net MVC web api

Asp.net mvc 4中出现的web api是用来实现REST.

关于什么是REST,可以看这里http://zh.wikipedia.org/zh/REST

 

通过ajax等访问 web api非常方便,但是如何在Winform, Silverlight等访问web api呢?

通过搜索,发现了已经有人做过这个东西了,就是RestSharp.

 RestSharp不只是访问web api, 访问其他平台的Rest API也是一样。

看看介绍的使用,无论是post数据,文件,格式化返回数据,异步请求都非常方便:

 

var client = new RestClient("http://example.com");
// client.Authenticator = new HttpBasicAuthenticator(username, password);

var request = new RestRequest("resource/{id}", Method.POST);
request.AddParameter("name", "value"); // adds to POST or URL querystring based on Method
request.AddUrlSegment("id", 123); // replaces matching token in request.Resource

// add parameters for all properties on an object
request.AddObject(object);

// or just whitelisted properties
request.AddObject(object, "PersonId", "Name", ...);

// easily add HTTP Headers
request.AddHeader("header", "value");

// add files to upload (works with compatible verbs)
request.AddFile(path);

// execute the request
RestResponse response = client.Execute(request);
var content = response.Content; // raw content as string

// or automatically deserialize result
// return content type is sniffed but can be explicitly set via RestClient.AddHandler();
RestResponse<Person> response2 = client.Execute<Person>(request);
var name = response2.Data.Name;

// or download and save file to disk
client.DownloadData(request).SaveAs(path);

// easy async support
client.ExecuteAsync(request, response => {
    Console.WriteLine(response.Content);
});

// async with deserialization
var asyncHandle = client.ExecuteAsync<Person>(request, response => {
    Console.WriteLine(response.Data.Name);
});

// abort the request on demand
asyncHandle.Abort();
