RestSharp

RestSharp是一个轻量的，不依赖任何第三方的模拟Http的组件或者类库。RestSharp具体以下特性；支持net4.0++，支持HTTP的GET, POST, PUT, HEAD, OPTIONS, DELETE等操作，支持oAuth 1, oAuth 2, Basic, NTLM and Parameter-based Authenticators等授权验证等。截止当前目前是github最高stars的http类库。

使用介绍

NuGet包

请求类型

• Method.Get
• Method.Post
• Method.Put
• Method.Delete
• Method.Patch
• Method.Head
• Method.Options
• Method.Merge
• Method.Copy
• Method.Search

Http标头

AddObject

var obj = new {
    status = 1,
    priority = "high",
    ids = new [] { "123", "456" }
};
request.AddObject(obj);

//或者 AddParameter(key, value);
request.AddParameter("status", 1);
request.AddParameter("priority", "high");
request.AddParameter("ids", "123,456");

AddUrlSegment

var request = new RestRequest("health/{entity}/status").AddUrlSegment("entity", "s2");
//请求地址会转换为 health/s2/status

AddStringBody

如果您有预序列化的有效负载（如 JSON 字符串），则可以使用它将其添加为正文参数。需要指定内容类型，以便远程终结点知道如何处理请求正文

var json = "{ data: { foo: \"bar\" } }";
request.AddStringBody(json, ContentType.Json);

JsonBody

• 指示 RestClient 在发出请求时将对象参数序列化为 JSON
• 将内容类型设置为application/json
• 将请求正文的内部数据类型设置为DataType.Json

不要将 JSON 字符串或某种实例发送到

var param = new MyClass { IntData = 1, StringData = "test123" };
request.AddJsonBody(param);

简单例子

        private async Task<RestResponse> RestSharpTest(string requestUrl,Method apiMethod)
        {
            var client = new RestClient(requestUrl);
            client.AcceptedContentTypes = new[] { "application/json", "text/json", "text/x-json", "text/javascript", "text/plain", "*/*" };
            var request = new RestRequest();
            switch (apiMethod)
            {
                case RequestTypeEnum.Get:
                    request = new RestRequest("", Method.Get);
                    break;

                case RequestTypeEnum.Post:
                    request = new RestRequest("", Method.Post);
                    break;

                case RequestTypeEnum.Put:
                    request = new RestRequest("", Method.Put);
                    break;

                case RequestTypeEnum.Patch:
                    request = new RestRequest("", Method.Patch);
                    break;

                case RequestTypeEnum.Delete:
                    request = new RestRequest("", Method.Delete);
                    break;

                default:
                    break;
            }
            request.AddHeader("Content-Type", "application/json");
            var response = await client.ExecuteAsync(request);
            return response;
        }
