Question

我正在尝试将数据发布到json api。这就是我的代码看起来的样子。它从服务器返回一个错误，那里的人告诉我，我发送的所有内容都是json字符串，我应该发布只有一个参数是JSON stirng的params。即。 contact_attributes应该包含如下所示的字符串：

“{\” 名称\ “：\” 雷\ “\ ”姓\“：\ ”达迪\“，\ ”passport_number \“：\” 00000020 \”，\ “unique_identifier \”：\ “7353280000000020 \”，\ “MSISDN \”： \ “27829042259 \”，\ “bank_account_number \”：空，\“bank_account_br anch_code \ “：空，\” bank_account_branch_name \ “：空，\” bank_detai ls_required \ “：虚假，\” membership_number \ “：空，\” bank_account_b ank_id \ “：空，\” bank_account_account_type_id \ “：空，\” bank_accou nt_initials \ “：空，\” bank_account_surname \ “：空，\” bank_account_p assport_number \ “：空，\” DATE_OF_BIRTH \ “：空，\” debit_day \ “：空，\” CON tract_sale_date \ “：空，\” CONTRACT_START_DATE \ “：NULL}”

我完全糊涂了，有谁知道我怎么做到这一点。

public class JsonSaleData
    {
        [DataMember]
        public string contact_attributes { get; set; }
        [DataMember]
        public string campaign_uuid = "9d119cce-25ea-46bc-b7bc-cba7e8323e91";
        [DataMember]
        public string user_credentials = "OCPdNbeltviij8C1RLcf";
        [DataMember]
        public string license_id = "1";

    }

private string PostSaleToClient(string url, JsonSaleData _SaleData)
        {


            string strResult = "";
            try
            {
                ASCIIEncoding encoding = new ASCIIEncoding();


                System.Net.HttpWebRequest httpWebRequest = (HttpWebRequest)System.Net.WebRequest.Create(url);
                httpWebRequest.Method = "POST";
                httpWebRequest.ContentType = "application/json; charset=utf-8";


                DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(JsonSaleData));
                MemoryStream ms = new MemoryStream();
                ser.WriteObject(ms, _SaleData);
                ms.Position = 0;
                String json = Encoding.UTF8.GetString(ms.ToArray());


                StreamWriter streamWriter = new StreamWriter(httpWebRequest.GetRequestStream());
                streamWriter.Write(json);
                streamWriter.Flush();
                streamWriter.Close();

                System.Net.HttpWebResponse httpWebResp = (HttpWebResponse)httpWebRequest.GetResponse();
                using (var streamReader = new StreamReader(httpWebResp.GetResponseStream()))
                {
                     strResult = streamReader.ReadToEnd();
                }

                return strResult;

            }
            catch (Exception ex)
            {
                string e = ex.Message;
            }

           return strResult;


        }

尝试使用以下函数处理JSON sring。

private string ConvertToJSON(objType obj)
  {

string sJSON = "{";

try {
    AppendToJSON(ref sJSON, "obj1Name", obj.obj1);
    AppendToJSON(ref sJSON, "obj2Name", obj.obj2);
    AppendToJSON(ref sJSON, "obj3Name", obj.obj3);
    AppendToJSON(ref sJSON, "obj4Name", obj.obj4);

    return sJSON.Substring(0, sJSON.Length - 1) + "}";

} catch (Exception ex) {
    return "";
}
 }
private void AppendToJSON(ref string byValJSON, string Name, string Value)
  {
byValJSON = byValJSON + "\"" + Name + "\":\"" + Value + "\",";
   }

将字符串发布到服务器。

using System.Web;

public class AttributesHandler : IHttpHandler
{

public void ProcessRequest(System.Web.HttpContext context)
   {
string JSON = null;
string timeOut = null;

timeOut = System.Web.HttpContext.Current.Server.ScriptTimeout;
try {
    System.Web.HttpContext.Current.Server.ScriptTimeout = 600;
    System.Web.HttpContext.Current.Response.ContentType = "text/javascript";
    System.Web.HttpContext.Current.Response.ContentEncoding = System.Text.Encoding.UTF8;
    JSON = ConvertToJSON(obj);
    System.Web.HttpContext.Current.Response.Write(JSON);

    System.Web.HttpContext.Current.Server.ScriptTimeout = timeOut;

} catch (Exception ex) {
}

   }
   }

使用DotNet代码调用：

string Url = "";
Url = "http://xxxxxxxxxxxxxx/AttributesHandler.ashx?cd=xx";
object @out = null;
try {
Net.WebClient webclient = new Net.WebClient();
webclient.UseDefaultCredentials = true;
@out = System.Text.Encoding.ASCII.GetString((webclient.DownloadData(Url)));
} catch (Exception ex) {
//out = ex.InnerException.ToString
}

这里他们只会将响应变为字符串。

使用Javascript Ajax。

$.ajax({
    type: "GET", timeout: 60000, cache: false, dataType: "jsonp", url: "http://xxxxxxxxxxxxxx/AttributesHandler.ashx?cd=xx"         
    success: function (response) {
        objAttributes = response.Attributes; //in object formate
                if (objCardAttributes != null) {
         //can process the objects
               }
                 __doPostBack('upToolkit',);
          },
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        var sReturn = "Please close the browser and relaunch ";
        if (textStatus != null) { sReturn += " Details: (" + textStatus + ")"; }
        if (errorThrown != null) { sReturn += " Description: (" + errorThrown.Description + ")"; }
       __doPostBack('upToolkit', sReturn);
    }
});

你的json和你的POCO不匹配......没有必要发布多个参数来向服务器发送数据..但是你的json在这种情况下没有翻译成POCO就是问题

“{\”name \“：\”Leigh \“，\”surname \“：\”Duddy \“，\”passport_number \“：\”00000020 \“，\”unique_identifier \“：\”7353280000000020 \“，\”msisdn \“：\”27829042259 \“，\”bank_account_number \“：null，\”bank_account_br anch_code \“：null，\”bank_account_branch_name \“：null，\”bank_detai ls_required \“：false，\ “membership_number”：null，\“bank_account_b ank_id \”：null，\“bank_account_account_type_id \”：null，\“bank_accou nt_initials \”：null，\“bank_account_surname \”：null，\“bank_account_p assport_number \”：null， \“date_of_birth \”：null，\“debit_day \”：null，\“con tract_sale_date \”：null，\“contract_start_date \”：null}“

转到www.json2csharp.com看你的json是不可解析的......

确保你的json是对的..

然后使用此站点创建csharp类并反序列化到该特定对象

发布多个参数一个JSON字符串
