通过Web客户端post方法C＃传递两个JSON对象

我需要在C＃中使用Web客户端方法将下面的对象作为post方法的参数传递。

{ "company": { "id": "e63dfcab345260b2591f585126ede56627db4ef2" }, "requestor": { "id": "", "email": "[e-mail] ", "firstName": "Test", "lastName": "Requestor", "role": "employerAdmin", "phone": "(415)1112222", "title": "HR Manager" } } 

我这样转换了

 company[id]=e63dfcab345260b2591f585126ede56627db4ef2&requestor[id]=&requestor[email]=[e-mail]+&requestor[firstName]=Test&requestor[lastName]=Requestor&requestor[role]=employerAdmin&requestor[phone]=(415)1112222&requestor[title]=HR+Manager 

但我得到无效的参数错误。 请帮我。 提前致谢。

我的整个代码如下：

  using (var Requestor = new System.Net.WebClient()) { string url = "https://stormaas-pre.inflection.com:8443/v1/Requestor?"; string parameters = "company[id]='757563a3-67df-4a6e-9ef9-d89d57d41e0d'&requestor[id]=''&requestor[email]='[e-mail]'&requestor[firstName]='Test'&requestor[lastName]='Requestor'&requestor[role]='employerAdmin'&requestor[phone]='(415)1112222'&requestor[title]='HRManager'"; Requestor.Headers.Add("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; .NET CLR 1.0.3705;)"); Requestor.Credentials = new System.Net.NetworkCredential("xyz:xyz!", ""); Requestor.Encoding = System.Text.Encoding.UTF8; Requestor.Headers[HttpRequestHeader.ContentType] = "application/json"; Requestor.Headers[HttpRequestHeader.Accept] = "text/xml"; string res = Requestor.UploadString(url, "POST", parameters); } 

Answer 1

您可以为Requestor，Company创建POCO类，如下所示，并使用JSON.net为您进行转换。

 public class Company { public string Id { get; set; } // Other properties } public class Requestor { public string Id { get; set; } public string Email { get; set; } public string FirstName { get; set; } public string LastName { get; set; } // Other properties } public class Container { public Company Company { get; set; } public Requestor Requestor { get; set; } } var requestor = new Container(); requestor.Company = new Company { Id = "sampleid" }; requestor.Requestor = new Requestor { FirstName = "test", LastName = "testname" }; JsonSerializerSettings settings = new JsonSerializerSettings(); settings.ContractResolver = new CamelCasePropertyNamesContractResolver(); var data = JsonConvert.SerializeObject(requestor, settings); WebClient client = new WebClient(); client.Headers.Add(HttpRequestHeader.ContentType, "application/json"); // Code for the credentials etc client.UploadString(@"your url", data); 

希望这可以帮助。 为此，您需要引用JSON.net。 由于您将.net 4.5与Web API一起使用，因此您应该已经拥有该引用。

您会收到无效的参数错误，因为url中不允许使用方括号。 如果要使用RFC 1738中未包含的字符，则必须使用HttpUtility.UrlEncode("String") （msdn reference ）
