Question

我想将数据发送到http://irsherkat.ssaa.ir/Design/SearchCompanyPublicInfo.aspx，其值为＃8xt1677542，用于#txtNationalCode输入。当我使用Fiddler向http://irsherkat.ssaa.ir/hndlr/GeneralHandler.ashx?Id=33发送请求时（已发布数据已发送到），请使用此请求标头：

Content-Type: application/x-www-form-urlencoded

和此请求正文：

Request={'ClassTypeName':'TRM.hndlr.Classes.CompanyPublicInfoController','MethodName':'SearchData','DataParamType':'TRM.hndlr.TRMTypeDefinition.CompanyPublicInfo.CompanyPublicInfoSerchParam','MainEntityType':'','DataParam':'{\'Nationalcode\':\'10861677542\',\'Registernumber\':\'\',\'UnitId\':null,\'CompanyTypeId\':\'0\'}'}

我获得了200个成功结果，但是当我想用这个C＃代码执行此操作时：

public async Task<string> Get()
    {
        var request = (HttpWebRequest)WebRequest.Create("http://irsherkat.ssaa.ir/hndlr/GeneralHandler.ashx?Id=33");

        var postData = "Request={'ClassTypeName':'TRM.hndlr.Classes.CompanyPublicInfoController','MethodName':'SearchData','DataParamType':'TRM.hndlr.TRMTypeDefinition.CompanyPublicInfo.CompanyPublicInfoSerchParam','MainEntityType':'','DataParam':'{\'Nationalcode\':\'10861677542\',\'Registernumber\':\'\',\'UnitId\':null,\'CompanyTypeId\':\'0\'}'}";
        var data = Encoding.ASCII.GetBytes(postData);

        request.Method = "POST";
        request.ContentType = "application/x-www-form-urlencoded";
        request.ContentLength = data.Length;

        using (var stream = request.GetRequestStream())
        {
            stream.Write(data, 0, data.Length);
        }

        var response = (HttpWebResponse)request.GetResponse();

        return new StreamReader(response.GetResponseStream()).ReadToEnd();
    }

它给了我这个错误：

The remote server returned an error: (500) Internal Server Error.

Answer 1

尝试从"Request="值中删除postData。

在另一个网站上输入数据并使用c＃获取回复
