1.传递匿名对象JSON格式  public string Pay(string apisecret, string apikey, string token) { try { string url = "https://******//test"; var client = new RestClient(url); var request = new RestRequest(Method.POST); var tran = new { merchant_ref = "Astonishing-Sale", transaction_type = "purchase" }; //生成随机数 RandomNumberGenerator rng = RNGCryptoServiceProvider.Create(); byte[] random = new Byte[8]; rng.GetBytes(random); string NONCE = Math.Abs(BitConverter.ToInt64(random, 0)).ToString(); //生成时间戳 string TIMESTAMP = ((long)(DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc)).TotalMilliseconds).ToString(); //获取JSON字符内容 string paybody = string.Empty; if (tran.transaction_type != null) { paybody = SimpleJson.SerializeObject(tran); } string auth = GetAuth(apisecret, apikey, token, paybody, NONCE, TIMESTAMP); request.AddHeader("Content-Type", "application/json"); request.AddHeader("apikey", apikey); request.AddHeader("token", token); request.AddHeader("Authorization", auth); request.AddHeader("nonce", NONCE); request.AddHeader("timestamp", TIMESTAMP); request.AddJsonBody(tran);//自动转换为JSON IRestResponse response = client.Execute(request); var content = response.Content; return content; } catch (Exception e) {return string.Empty; } } 2.multipart/form-data上传文件 根据Restsharp源码可以发现如果使用了AddFile了会自动添加multipart/form-data参数 string server = "http://*****//Upload"; string picurl = "C:\\Users\\Administrator\\Desktop\\555.png"; string testparams = "testpicupload"; RestClient restClient = new RestClient(server); //restClient.Encoding = Encoding.GetEncoding("GBK");//设置编码格式 RestRequest restRequest = new RestRequest("/images"); restRequest.RequestFormat = DataFormat.Json; restRequest.Method = Method.POST; //restRequest.AddHeader("Authorization", "Authorization");//当需要设置认证Token等情况时使用默认不需要 //restRequest.AddHeader("Content-Type", "multipart/form-data");//如果使用了AddFile会自动添加否则请手动设置 restRequest.AddParameter("test", testparams); // restRequest.AddFile("pic", picurl);//压缩格式 restRequest.AddFile("pic", picurl, contentType: "application/x-img"); //非压缩格式 如果此处不设置为contentType 则默认压缩格式 var response = restClient.Execute(restRequest); var info= response.Content; 3.直接传递不带参数的RequestBody：有的时候接口并不包含参数名而是直接以body流的方式传输的这时候使用上面添加参数的方式就无效了，如果发送呢，RestSharp里保留了AddBody和 ParameterType.RequestBody来实现
根据AddBody源码发现实际转换最终使用的都是 AddParameter(contentType, serialized, ParameterType.RequestBody) 这个方法 public IRestRequest AddBody(object obj, string xmlNamespace) { string serialized; string contentType; switch (this.RequestFormat) { case DataFormat.Json: serialized = this.JsonSerializer.Serialize(obj); contentType = this.JsonSerializer.ContentType; break; case DataFormat.Xml: this.XmlSerializer.Namespace = xmlNamespace; serialized = this.XmlSerializer.Serialize(obj); contentType = this.XmlSerializer.ContentType; break; default: serialized = ""; contentType = ""; break; } // passing the content type as the parameter name because there can only be // one parameter with ParameterType.RequestBody so name isn't used otherwise // it's a hack, but it works :) return this.AddParameter(contentType, serialized, ParameterType.RequestBody); } /// <summary> /// Adds a parameter to the request. There are four types of parameters: /// - GetOrPost: Either a QueryString value or encoded form value based on method /// - HttpHeader: Adds the name/value pair to the HTTP request's Headers collection /// - UrlSegment: Inserted into URL if there is a matching url token e.g. {AccountId} /// - RequestBody: Used by AddBody() (not recommended to use directly) /// </summary> /// <param name="name">Name of the parameter</param> /// <param name="value">Value of the parameter</param> /// <param name="type">The type of parameter to add</param> /// <returns>This request</returns> public IRestRequest AddParameter(string name, object value, ParameterType type) { return this.AddParameter(new Parameter { Name = name, Value = value, Type = type }); } 4..二进制数据：(如下方式发送的格式和直接使用二进制写入是相同的) string server = "http://******/Upload";
RestClient restClient = new RestClient(server);
restClient.Encoding = Encoding.GetEncoding("GBK");//设置编码格式
RestRequest restRequest = new RestRequest(Method.POST);
restRequest.Method = Method.POST;
var bb = new byte[] { 0x30, 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x12, 0x40, 0x42 };
restRequest.AddParameter("application/pdf", bb, ParameterType.RequestBody);
var response = restClient.Execute(restRequest);
string s = response.Content;
